Top Ten Air Conditioners in India by electricity consumption and size in 2017

By on August 10, 2017

For all the households using air conditioners, a major component of electricity bill is contributed by the air conditioners. If you are someone who is worried about high electricity bills due to air conditioners then buying energy efficient air conditioner makes much more sense to you. There are multiple types and brands of air conditioners available in the market today. Everyone wishes to be informed before making a buying decision of an air conditioner. Most sources on the Internet provide details on features and reviews. Electricity consumption hardly becomes the deciding factor. To help people make electricity consumption as deciding factor, we at Bijli Bachao have decided to put up a list of Top Ten air conditioners in India by electricity consumption and size.


Best AC brands in India

  • Hitachi
  • Daikin
  • Mitsubishi (Heavy and Electric)
  • O General
  • Blue Star

These are considered as premium brands for Air Conditioners in India. Out of these Hitachi, Daikin, Mitsubishi and General are Japanese brands while Blue Star is an Indian brand. These brands are known for their refrigeration technology and thus offer quite robust products. Hitachi, Daikin and Blue Star also offer great energy efficient models and typically rank high in our top rankings (based on BEE data). Other brands that are really good include: LG, Samsung, Voltas, Godrej, Whirlpool, Carrier, Toshiba and Panasonic. This brand value mentioned over here is based on our perception of various brands available in India. Some people may have had good experience with other brands as well, but then their market presence is too small to make a judgement.
The list of top models below does not involve this perception and is purely based on data from BEE (Bureau of Energy Efficiency) on energy efficiency (or electricity consumption). Before choosing a brand, you must also ensure that the brand is present in your city/locality and is able to provide good service for your purchased product.

Best Window AC in India

Energy efficiency standards for window air conditioners have not been improved since quite some time. The result is that window air conditioners are much less energy efficient or more electricity consuming as compared to split air conditioners. Even the BEE star ratings of window ACs is 1 level lower as compared to split ACs. So a BEE 5 star rated window AC is equal in electricity consumption to BEE 4 star rated split AC. On top of that most energy efficient options are available in 1.5 ton category rather than 1 ton or 2 ton. In fact there are hardly any 2 ton models in market. In general we recommend people to go for Split AC unless they have a constraint. Still below are the most energy efficient models:

The Basis of this ranking:

  • The basis of this ranking is the data from BEE (Bureau of Energy Efficiency) for the fixed speed and inverter technology air conditioners. BEE data contains ISEER, Annual Electricity Consumption (in units consumed for 1600 hrs of usage), cooling capacity and power consumption and this information is self reported by the manufacturers. The values are calculated under test conditions. To understand more about ISEER and BEE’s new star rating standards please check this link: link.
  • We have taken the data on annual electricity consumption and categorized it by the marketing tonnage of the air conditioner. The air conditioner with the lowest annual electricity consumption is given the highest ranking. Multiple models with the same value are given the same rank.
  • It is important to note that knowing Cooling Capacity of an air conditioner is very important because for same tonnage the cooling capacity of various models vary. The higher the cooling capacity more heat an air conditioner can remove.
  • It is also important to size an air conditioner for a room properly. An oversized air conditioner cannot remove humidity properly and undersized will keep running all the time increasing electricity consumption. So it is important to choose right cooling capacity.
  • The list below contains only the top ten ranked air conditioners. List of all BEE star rated air conditioners are available on the useful links given below.
  • We have not listed Window Air Conditioners because there are no energy efficient options available in Window Air Conditioners and it is better to go for Split Air Conditioners.
  • We regularly update this list as new models get added in the BEE list of air conditioners.
  • The data is as per BEE’s standards as applicable in 2017. As per current standards, BEE has started publishing annual electricity consumption data for air conditioners assuming usage to be 1600 hrs a year.

FAQs for Buying ACs in India

Here are some quick FAQs from people who are looking to buy ACs in India:

  • 1) What is the size of AC that I should buy for my room?

    Size of an AC is a very important aspect that one should evaluate before buying an AC. Oversized AC can significantly increase electricity consumption while undersized may not cool properly. You can use the calculator given on the bottom of this page to evaluate your needs: AC Calculator Link

  • 2) Which star rating would be good for me?

    The choice of star rating depends on the hours that you use your AC for and the electricity tariffs in your area. Typically we do not recommend going for anything less than BEE 3 star rating. However your exact need can be evaluated using the calculator given on the bottom of this page: AC Calculator Link. You can input your daily and yearly consumption values and the calculator will suggest you the right star rating based on your use. It will also provide you approximate amount of money that you will pay for electricity if you choose a particular star rated AC. This can help you evaluate the benefit of a specific star rating.

  • 3) What are Inverter ACs?

    Inverter AC is the latest energy efficient (electricity saving) technology which is available in the market. It has the potential to save 30-60% electricity depending on your choice of the model. You can read more about Inverter ACs on this link: Air Conditioners with Inverter technology can help save electricity

  • 4) I saw a BEE star rating for an Inverter AC. Is it valid?

    BEE star rating was not available for inverter technology till the year 2015. But BEE has introduced star rating for inverter ACs in 2016. It is not a mandatory rating so it is not necessary for all manufacturers to get their AC model rated, but some have started using the same as many consumers believe in star ratings. The ratings will become mandatory in 3 years.

    However, the rating standards for inverter ACs and fixed speed ACs are different. A BEE 3 star rated inverter AC will still be more efficient than a BEE 5 star rated fixed speed AC. But BEE 2 or 1 star rated inverter AC may not be as efficient as BEE 5 star rated fixed speed AC.

  • 5) I have less use of AC, is Inverter AC still be better for me?

    It all depends on your usage of AC and tariffs. If your usage is high and tariff is also high, then it will be much better to go for inverter AC. For e.g. in places like Mumbai where tariff is already Rs 11-12 per unit for last slab, even a decent nightly use for 3 summer months would be better off with an inverter AC than a regular AC. But then it depends on your usage and tariff.

  • 6) My dealer tells me to buy a 3 star AC as Inverter AC is good only if I use it for 18 hours daily throughout the year. Is it true?

    Most dealers are less equipped or trained on the technicalities and evaluation of ACs. Many a times they are not updated with latest information. Dealer training is one of the biggest challenges for energy efficiency. We would suggest that you use the calculator given on the bottom of this page to evaluate your needs: AC Calculator Link . You can see the numbers on right side of the calculator to see how much you will be paying for electricity if you go for a specific star rating.

  • 7) Is it beneficial to go for a bigger tonnage AC? Will it cool better?

    Not really. In fact bigger tonnage ACs consume much more electricity. And they overcool. So if you set temperature to 25 degrees in thermostat, it will make the room cooler than that (more on this link: Oversizing ACs). A right sized AC is far better than oversized or undersized AC.

  • 8) Can I go for a smaller sized AC from what the calculator suggests me? Will it save electricity for me?

    It is always better to right size an AC because oversizing increases electricity consumption and undersizing does not cool well. However undersizing can save electricity. Ideally sizing is done to assure that AC can cool well up to 25 degree centigrade. If you slightly undersize then it may cool only up to 27-28. And will save electricity as well. But then it cannot be equal to buying 1 ton AC when you need 1.5 ton (as that will be gross undersizing). It can be done if you buy 1 ton instead of 1.2 ton. Also sizing is done considering peak summer temperature in mind. If your usage is mostly at night (when temperature is much less) then you may consider buying an undersized AC as well.

    Another situation where you can think of undersizing is if you plan to set up an AC in your living room which is huge. For a huge space cooling requirement is much high and if you try to rightsize the AC then you would need a huge AC. In such case you can undersize the AC and setup one close to the seating area (area where cool air is required). This will make sure that the seating area remains comfortable and you do not end up putting up a huge AC that can cost you a lot on electricity bills.

  • 9) Which brand is good?

    This is the most common question we get which is most difficult to answer. We have tried to answer this on our link: Which is the best brand to buy?. A lot of it is perception based on experience. However these are the brands that you will most likely find in our recommendations: Daikin, Hitachi, Sharp, Panasonic, General, Mitsubishi, Carrier, Blue Star, LG, Voltas, Samsung, Godrej. Not that other companies are bad, but these are top most. The only brands that we do not recommend to buy are the brands that used to be retailers and now have started selling ACs under their own brand names.

  • 10) Which brand gives best service in my area?

    This is again a very common question and extremely difficult to answer. Most of our analysis is purely technical based on the specifications of various models. Service levels depends on local service stations of various brands. It varies from city to city. Even within the city the service levels may vary. The best people to provide you suggestions regarding this are your local dealers and people who have used a particular brand.

  • 11) What is EER? How can I use EER to compare ACs? How does EER of inverter AC compare to EER of other ACs?

    EER or Energy Efficiency Ratio is a representation of how well an AC uses electricity. Higher the number, better the use of electricity by an AC. By no means is it a representation of actual electricity consumption. A 1 ton AC and 1.5 ton AC can have same EER but their electricity consumption will differ. And that is because 1.5 ton AC has to do more work than 1 ton AC. Same EER just means that they are equally good at using a unit of electricity.

    However inverter technology is slightly different. Although usage of EER is not the right representation of an Inverter AC but many manufacturers do put the same for inverter ACs as well. If you want to do a right comparison then divide the EER of inverter AC by 0.8 (assuming it is just 20% more efficient than fixed speed AC .. however it can be more). So if you want to compare two ACs inverter and non inverter both of EER 3.3 then divide 3.3 by 0.8 to get comparison EER of inverter AC. Please note 20% is just pessimistic efficiency level for inverter AC. It can be more.

  • 12) Is a lower EER of inverter AC better than higher EER of fixed speed AC?

    FAQ no 11 above gives a good answer for this. In most cases even a lower EER of Inverter AC will be better than higher EER of BEE 5 star rated fixed speed AC. But still we recommend that you go for an inverter AC of EER 3.2 and above (at least).

  • 13) I want to buy copper condenser but the model specification says it is pre-coated aluminium fins. Is it really copper?

    To explain this, first let us explain types of condensers that are available in the market:

    a) PFC (Parallel Flow Condenser) or Multi Jet which is all aluminium. It is highly energy efficient but if it fails it need to be replaced. Although they come with anti corrosion coatings, but still fixing the small multi channels in case of clogging is difficult. Manufacturers specifically mention PFC or Multi Jet. PFC will look like this: PFC

    b) Coil and Fin type condenser, where coils are copper and fins are aluminium. Even in this the one with anti corrosion coating (also known as blue fin/gold fin) is better. Most brands have such type of condenser. You can ask the dealer to open the outdoor and indoor unit for you and you can check if it looks blue or not. Blue fin is the best for corrosion protection. Blue fin will look like this: blue_fin_condenser

    Now it is not that copper cannot corrode. What is important is to select a condenser that has anti corrosion coating. So ask for a condenser with copper pipes and pre coated aluminium fin. Even if it is aluminium then it should be coated with corrosion protection. When an AC spec says that it has pre-coated aluminium fins it is a coil and fin type condenser which is copper.

  • 14) I have a tight budget, should I go for a window AC?

    Window ACs have efficiency levels 1 level lower than split ACs. So a BEE 5 star rated window AC is equivalent in efficiency to BEE 4 star rated split AC. The reason for the same is that manufacturers have started reducing number of window AC models and have started solely focussing on split ACs. Most of the new technology is available only in split ACs. In fact only BEE 5 star rating is available only in 1.5 ton window ACs. 1 and 2 ton window ACs do not have BEE 5 star rated options. And even the 5 star rated 1.5 ton window ACs are equivalent to BEE 4 star rated split ACs. So our recommendation is to go for a split AC. However, if you are really tight on budget and you need 1.5 ton AC then you can go for BEE 5 star rated window AC. But if you need 1 or 2 ton AC then better go with split AC.

  • 15) Which refrigerant is environment friendly?

    R410A, R32 & R290 are the most environment friendly refrigerants in ACs. R410A is non flammable, R32 is mildly flammable and R290 is highly flammable refrigerant. If you are planning to buy an AC with refrigerant that is flammable then we would recommend you to go for a good brand as better brands do take care of safety related issues with the refrigerants. For safe choice you can go with R410A. Daikin uses R32 but it is a very reliable brand.

  • 16) Should I buy an AC online?

    Depends a lot on who is the seller. These days online websites are marketplaces which means they are not the direct sellers. One of the biggest issue with online buying is to get right warranty and support from the brand. If the seller is an authorised seller, you will get warranty as well as support. If seller is not authorised then the same becomes extremely difficult. Although portals do claim to sell original products, but it is extremely important to check seller reviews and confirm if you will get warranty on product or not.

  • 17) Do you have any specific suggestion for me based on my budget?

    Our suggestions are mostly based on energy efficiency of the model and the top brands (as listed in FAQ 9). We do not recommend any specific brand because everyone has a different experience with a brand. Also the service levels of various brands differs at various locations (as stated in FAQ 10). In fact many people who visit review websites like mouthshut get negative reviews of almost every brand. The reason for the same is that it is practically impossible for any brand to satisfy each and every consumer. The best thing that we can suggest you is to look at the list of top brands above, choose the brand that you like (or get a good feedback on from local dealers), then select the most efficient model of your tonnage requirement from this list: http://bit.ly/OpE1JR. If you do not find that model in the market, then just go for the model with highest EER in your preferred brand and suggested star rating.

  • 18) What is the electricity consumption of a specific AC?

    We have listed the power consumption of almost all ACs available in market on this link: http://bit.ly/OpE1JR. However, the number listed on this page is wattage of AC. To convert it into units per hour, you will have to divide the wattage by 1000 (so a 1450 W would convert to 1.45 units). Another point to note is that the actual consumption will not be just wattage divided by 1000. It will depend on temperature setting as well as various other factors. However, to get a ballpark number just multiple the unit per hour value that you have got in previous step by 0.8 (for fixed speed AC assuming compressor runs for 80% of the time) and 0.64 (for inverter AC assuming inverter AC to be 20% more efficient than fixed speed AC). So if an AC is rated at 1450 W, then if it is fixed speed AC then its power consumption would be (1450/1000) * 0.8 = 1.16 units per hour and if it is inverter AC then it would be (1450/1000) * 0.64 = 0.928 units per hour. Please note that these are just approximate values and power consumption of AC depends on several factors listed on this page: Things that impact electricity consumption in air conditioners

  • 19) Your calculator tells me a certain size for my room, is it correct?

    The calculation by the calculator is absolutely correct as per our knowledge. We have put in all the knowledge that we have about AC sizing in this calculator. We will provide you the same number even if you ask us personally.

  • 20) Is stabiliser required for my AC?

    If there are huge voltage fluctuations in your area then you must go for a stabiliser for your AC. It is more important if you go for a fixed speed AC. Inverter ACs can handle voltage fluctuations much better, however they have electronics that are prone to damage in case there is power surge (sudden increase of current as it happens in case of short circuits). So Inverter ACs should be protected from surges. A surge guard should be good enough for inverter ACs. If you still feel that you should put a stabiliser for inverter AC then you should go for one with surge protection feature.

  • 21) There is a significant price difference between a BEE 3 star rated AC and Inverter AC. Is Inverter AC really worth it?

    Inverter ACs save much more electricity as compared to BEE 3 star rated ACs. They can save electricity even if you use AC for 1 hour. However what is important is to analyse how much money you can save by using inverter AC as compared to how much extra do you pay for buying it. The calculator on this link: AC Calculator Link can help you figure out the yearly electricity cost difference that you will incur if you go for a BEE 3 star rated AC as compared to Inverter AC. This can help you make a decision to go for right type of AC.

  • 22) What is Bluefin/Gold Fin Technology? Is it copper?

    As we have mentioned in FAQ 13 above, Blue Fin and Gold Fin both are copper. Please refer to that FAQ to understand more about technology. You can also refer to this link: Air Conditioners: Copper Coil vs Aluminium Coil

  • 23) Which Air Filters are necessary for my use?

    The reason air filters are required in an AC is because ACs are meant to cool closed spaces. ACs do not take air from outside (unlike air cooler), they just cool the indoor air and circulate it. If the room (where AC is installed) remains closed for a long time, the quality of air deteriorates. It can result in accumulation of bacteria. Air Filters help improve the quality of air. However, it is important only if the room remains closed for a long time. It may be helpful even if you use it for 8-10 hours at night. Various brands have different kind of filters. It is more of a safety feature. Not absolutely necessary but good to have. You can choose the one that you feel you need.

  • 24) Will it be fine if I go for an Aluminium Condenser?

    It is absolutely fine if you go for an aluminium condenser if your area is not hot and humid. Biggest problem with aluminium condenser is corrosion. If the environment is not corrosive then it will not fail. And in fact Aluminium Condensers have high energy efficiency as well. Brands l like Samsung that have aluminium PFC condenser provide good enough corrosion protection for the condensers as well. In fact Samsung gives warranty on condenser too. People in many places have been using ACs with PFC condenser since quite some time and they have not failed. Their chance of failure is high only if the environment is corrosive, otherwise they can be a great choice.

  • 25) The models you have listed are not available in the stores. What do I do?

    Our data collection is based on data from BEE and models listed by brands on their website. We also try to check if the models are available in online stores. But it is possible that those models are not available in physical stores. Stores typically keep only those models that sell more (not necessarily energy efficient). You can try contacting authorised dealers of the brand and if you do not find any model with them, then the best bet is to go for the most energy efficient model that you get from your selected brands. We try updating our database every 2-3 months but it is possible that some of the models that we have collected are either very new or even discontinued ones.

  • 26) I have a shop/commercial establishment. Can you please help me buy an AC for that?

    Sizing an Air Conditioner involves taking a lot of environmental factors into consideration. A whole lot of things impact sizing as we have listed on our article Things that impact electricity consumption in air conditioners. As far as residential setups are concerned, things that are kept in a room and environment can be standardised (as we have done for the calculator) or can be assumed. But it is extremely difficult to assume or standardise a commercial setup or shop. A shop may be filled with a lot of products, or a commercial establishment can have a whole lot of people seated in it or equipments installed in it. Everything impacts electricity consumption. Thus it is very hard for us to evaluate or calculate requirement for a shop or commercial establishment. In fact the calculator that we have may not work perfectly for shop/commercial establishments. It is always better to get technical evaluation done by engineers from a reputed brand. If you want to install AC for your shop/commercial establishment, the best thing to do is to call a dealer of a brand that you want to go for and ask them to send an engineer to evaluate.

  • 27) How does Air Flow Rate (or Air Delivery) of AC impact cooling?

    Air Flow is an important aspect for cooling a room. High Air Flow can result in cooling a larger area and even faster cooling. Air Flow depends on fan speed. In general if you keep high fan speed the air circulation would be more and thus air will cool faster. Increase air circulation also results in a farther reach of cooling. So if you have a choice then of for AC with higher air flow rate.

Hi Abhishek,

I am from Jaipur and looking to buy 2T - 2 nos. & 1.5T-6 nos. inverter 5 star ac. I reside in an apartment (facing SW) with 10 floors above mine.

Have shortlisted the following for 1.5T (usage - Variable) :
Daikin - JTKM50SRV16; Hitachi - RSA518CAEA; Mitsubishi - SRK18YL-s; IFB - IACS18JCHTGC; Godrej - GSC18GIG5DGOG
Kindly advice which will give me best after sale services and any other make/model u suggest.

Pls advice make/model for 2T AC

Usage:
1st unit - 18hrs/day x 9 mths
2nd unit - 8hrs/day x 8 mths (must be Hot & Cold)

Thxs

Abhishek Jain (Mod)

But please note, Mitsubishi Heavy is a very expensive brand. They have fantastic products but are very expensive.

Abhishek Jain (Mod)

Hi,

In 2 ton category, there are very few BEE 5 star rated models in BEE database. Please note, a whole lot of models that sell as 2 ton are actually 1.8 ton. And I am talking about true 2 ton ACs. And I hope you have used the calculator on this page to get the right tonnage. If you are looking for 2 Ton then you can look at these:

Mitsubishi Electric MSY-GK24VA (Amazon link: http://amzn.to/2uPvwc6 ) ... 1.9 ton model
Hitachi RMA524CAEA ... 2 ton model.

Else you can also look at 2.2 ton models:

Mitsubishi Electric MSY-GN26VF-D1

For hot and cold, Daikin FTXS 2.2 ton is a good model. The same series has 1.8 ton as well. Daikin FTHP is BEE 4 star rated 1.8 ton model as well. For the 2nd room FTHP will also be good enough.

For 1.5 ton Daikin JTKM is the most energy efficient model and even Hitachi 18CAEA would be quite close (as per BEE data). But if we go by company claims (because the models is not rated on BEE ratings as it is not mandatory for inverter ACs), then Mitsubishi – SRK18YL-s would be the most energy efficient and highly durable model. If you have good service of Mitsubishi Heavy in your city then this would be a great model.

Hi Abhishek,

Thxs for the guidance. really appreciate.

Was looking at the review of Mitsubishi after sale service and unfortunately the number of unsatisfied customers are way way more than satisfied. A cause of concern there.

For the number of 1.5T ac's required is it a better option to go for multi split.
Wanted to go for VRF but unable to accommodate the ODU due to its size.

If multi split is good, pls provide the make/model.

Thxs

Abhishek Jain (Mod)

With VRF or Multi-split, the cost of purchase is higher but maintenance is much easier and cheaper. With multiple split ACs, the cost of purchase will be lower but maintenance will be higher and complex. On the whole, it will all depend on the usage and the deal that you get. You can find Multi Split in Daikin, Bluestar and LG. If Mitsubishi after sales service is not good then you can check on the after sales service of other brands like Daikin and Hitachi as well.

I have read BEE star & EER efficiency are well explained in detail gives us much knowledge for choosing the right ac also am interested to know which AC from 1 or 1.5 ton gives best range efficient in cooling performance

7
Abhishek Jain (Mod)

Higher the tonnage higher is the cooling capacity of the AC. 1 ton is equivalent to 12000 BTU/hr or it can remove 12000 BTUs of heat in an hour. Similarly, 1.5 ton is 18000 BTU/hr. But that does not mean that 1.5 ton is always better than 1 ton. It depends on the heat load of the room where the AC is to be fitted. If a room needs 1 ton and you put a 1.5 ton in it, then it will not be effective in removing humidity and it will also consume more electricity. So one cannot say that 1.5 ton gives the best cooling performance as compared to 1 ton. You need to right-size your AC to get the best efficient cooling performance. And that is why we have put the calculator on this page so that people can calculate the right size while buying an AC.

Hi Abhishek, im running system server machines as like atm machine in 70sq ft room which locate non direct face sun light, im confused to go with 5star r inverter 5star.kindly suggest me best split ac for my requirement which run 24*7*365 (from daikin mitshubshi r hitachi or any other specify )

9
Abhishek Jain (Mod)

For your usage a BEE 5 star rated inverter AC would be better. I think a 1-ton BEE 5-star inverter AC should be good (assuming the server machines will be packed and would be releasing heat). Going for the most efficient one would be the best. I think Mitsubishi Heavy SRK10YYL-S would be the best model. But you may also look at Daikin JTKM35 or Hitachi Kashikoi 5400i as well.

10

as i inquired in showroom they suggested mitshubshi electric inverter 410. 1.5ton wch cost 65k and non inverter 410 1.5 ton cost 50k... kindly suggest suitable match for me from above or specify any other

11
Abhishek Jain (Mod)

BEE 5 star inverter will be better for you.

Hi Abhishek,

Regarding my CARRIER SUPERIA CYCLOJET ac - I was planning to install the cylindrical Outdoor unit at my balcony. But, since the height of the ODU is quite large, it cant be placed above the window - as then it touches the ceiling surface. In that case, i was thinking of installing it in the wall at the level of the window..
But the local technicians are saying that if the ODU is placed at a height below the IDU (which will be the scenario in this case if ODU is fitted at window level) - then the AC compressor performance will be low..

>> 1. Is it true?? And if so, what will be your suggestion/..
>> 2. Moreover, I am against the idea of installing the ODU outside - as:
A. the distance between IDU & ODU will be larger in that case.. B. Since ODU is cyclojet with the top Open - it will be exposed to all the rain water & dust thru the year around. What's your take on that??

13
Abhishek Jain (Mod)

Well, it depends on how low is the ODU below the IDU. Certainly, the refrigerant has to go against gravity so some extra effort will be required. But extra will depend on the height difference. If the difference in height is not much then it will not be significantly low performance.

For your 2nd question, I do not have much feedback on the same as Cyclojet is a new product from Carrier and although technically I do not see any challenge with the design, practical issues are not known yet (as the product is new).

Dear Sir,
An ac has to be bought for a super senior citizen aged 85 + in Chembur , a suburb in North Mumbai .
Was confused at going through the Daikin website as they show ac s’ with anti corrosion treatment, different filters 0.1, 2.5pm , anti microbial , silver particle filter varieties
Would you please advise the efficiency rating , durability, cost of each replacement and if these are interchangeable across the various models of same tonnage ?
Thanks

15
Abhishek Jain (Mod)

Hello Sir,

Anti Corrosion treatment is an important aspect, but all other filters are like additional features and it truly depends whether you need them or not. They are not necessary to have. Also, I am not sure if they are interchangeable across various models or not and what will be their costs.

As for durability, all Daikin models come with copper. Some of them have anti-corrosion treatment (the models with model number ending with E like JTKP-E) but not all of them have anti-corrosion treatment. The severity of need of anti-corrosion treatment depends on how close you are to the Sea or how corrosive is the environment. I have many friends in Powai who have been using Daikin (regular models) for quite some time without any issues. But if your environment is corrosive, it will be better to go for models with anti-corrosion treatment.

Now to buy an AC, a few things are very important to decide:

1) Tonnage: Extremely important as undersized ACs do not cool the room properly and oversized consume more electricity and make environment uncomfortable by overcooling and are ineffective in removing humidity. I would strongly suggest that you use the calculator on this page to size the AC properly.

2) The efficiency rating or star rating: will depend on your usage of AC. Electricity tariffs in Mumbai are really high and thus we usually recommend going for better efficiency models in Mumbai. Unless your usage is less than 1000 hrs a year in Mumbai, I would strongly suggest you go for an inverter technology air conditioner. If it is close to 2000 hrs, then going for BEE 5 star rated inverter AC would be a must. Else between 1000-2000 hrs a year a BEE 3 star inverter AC would be good.

I would suggest that you check the right size using the calculator and let me know your usage (in hrs per year) and your budget, then I can recommend some models to you.

16

Dear Sir, Kudos to you for compiling such a great website. A suggestion - While trying to list the best ACs under various categories, please also indicate if the AC has a copper or a aluminium condenser. For many customers copper condenser makes lot of sense as it has long life and for some reason an issue crops up; it can be repaired rather than replacing it as in the case of an aluminium condenser. Please carry on the good work.

17
Abhishek Jain (Mod)

Hello Mr Prashant,

We did compile a list of copper and aluminium condenser data in association with International Copper Association of India and it is available on this link: https://www.bijlibachao.com/air-conditioners/air-conditioners-copper-coil-vs-aluminium-coil.html

However, the feedback we received was only from a few brands (not all) and even then the data was a bit confusing (mismatch between what is available in the market and what was provided by brands). And then there were missing model numbers. And in general this does not happen like an ongoing process and we get data from ICAI once in a year. And new models keep coming out. So it is a bit challenging to compile the same. But we do try from our side.

18

Hi Abhishek,

As you would have noted in one of my previous post - after discussion with my family - I went for 3 star - since the daily average consumption of my AC would be 5 - 6 hrs only..Thats why I choose 3 star of the carrier model suggested by you..
My query is: apart from being 3 star - my model: CACS18SU3J3 - does it have all the other identical properties as the Carrier superia 5 star ac that u actually suggested??
Plz confirm..

19
Abhishek Jain (Mod)

Features are the same in BEE 3 and 5 stars. Only the energy efficiency differ.

20

Moreover, in the net I am getting the some diff technical specifications - some says the model - is Copper condenser / some others say it is Aluminium..Please check & let me know which is the correct one & the URL where I will get the genuine features of the product I received..

21
Abhishek Jain (Mod)

This is the link to the details of model you received: http://www.carriermideaindia.com/superia-3-star.aspx

And this is the one I suggested: http://www.carriermideaindia.com/superia.aspx

22
Abhishek Jain (Mod)

All Carrier models are copper condenser models. Carrier does not sell Aluminium ones.

23

HI Abhishek,

I received my AC today. Model Number is CACS18SU3J3 - But on cover it is written as '18K Superia'.. Is it the same as Superia AC that you advised / it is the wrong model?? Plesae reply ASAP.

24
Abhishek Jain (Mod)

This is a wrong one. This is a BEE 3 star rated model. CACS18SU5J3 is BEE 5 star Carrier Superia. CACS18SU3J3 is BEE 3 star carrier Superia. It should be 5J3 and not 3J3. This will have more electricity consumption.

25

Hi
I need advice on buying an AC for my office. The dimensions are 17ft x 13ft x 10ft. It is located in rajasthan. It is north west facing with total exposure of about 160 sqft to sun. It has high inflow/outflow of customers. Please suggest whether to go for Mitsubishi Heavy - SRK25CSS-S6/A OR HITACHI - RAU524AVD. Or any other

26

Hi Anirudh,

Difficult to suggest anything. Based on the basic calculation of 4 people in the room the tonnage value that I think is required is 2.5 ton. But then a lot depends on the number of people in the room at any given time because every human releases heat. A 100 sq ft room may need 1-ton cooling without people, but then if you fill 20 people in the room then 1 ton will be grossly insufficient. So a lot depends on the number of people as well. I would say go for 3 ton in total so put two 1.5 ton inverter ACs in the office. And if the office will be packed with people, then you may need more.

27

Hi,
I live in Pune and plan to buy Hot and Cold AC. The room size in 180 sq.ft with ceiling ht: 10ft. The ceiling has a terrace directly above and the room is North East.

Winter usage is estimated for 2 months with 8hours / day consumption. Summer usage will be 2-3 months.

Which is the best AC brand to buy and what tonnage will be best suited for my requirement.

Thanks

28
Abhishek Jain (Mod)

I think 1.5 ton AC should be fine for your room, but if you have doubt then at best you can go for a 1.8 ton hot and cold inverter AC. Daikin FTHP50 (1.5 ton) or FTHP60 (1.8 ton) would be great choice if you want hot and cold AC.

29

hi abhishek ,i want to buy 1.5 ton inverter 3 star ac for my living room 18*12 , i am living in Dhule Maharashtra , after reading your blog i have opted for daikin fkth series but service center issue i leave it then i opted for lg Q18NPXA ,bule satar. & panasonic as LG providing 10 years compressor warranty other 2 only for 5 years whereas bule satar. & panasonic providing various air filters , does it really works such as catechin filter vitamin c filter does this increases power consumption or does it have more maintenance ?so im getting bit confused blue star also providing heat mode at a price up to 45k dose it consume too much power or is it really value for money ? or does it have more maintenance? wat abt various air filters used in other than LG
my baisc requirement is 1.5 ton inverter 3 star ac

30
Abhishek Jain (Mod)

Here are a few points to note:

1) Filters are just mechanical filters (just like a "channi" in hindi or a tea strainer) .... they do not consume any electricity, they just filter out particles. Filters require cleaning and also have limited life (some of them) and thus they need to be changed regularly (just like if you have a RO water purifier, you need to change its filters). A basic filter does not need frequent changing, only the specialized ones like Vitamin C, etc will need a change after some time to be as effective.

2) All split ACs have basic air filter for removing dust and it is required to clean them every 6 months. So basic cleaning of filter is required for every AC.

3) One should not go for Hot and Cold AC unless there is good enough (2 months or more) of heating requirement. You will be better off with non heating options.

4) LG has some models that have filters from 3M for advanced dust and pollution removal. Some models do not have it. The model you are looking at does not have that filter, but then it still has basic dust filter which is there in all Split ACs.

Filters do work and so make environment better. They need regular cleaning and maintenance (required in every AC even for basic filter). Some advanced filters may need regular change as they may become ineffective after some time.

Hi Abhishek,

Thanx for your response..

Re: the Voltage stabilizier point:
>> As i mentioned earlier - I am buying a Carrier Superia Cyclojet 1.5 Ton / 3 Star AC ..

1. What is its operating voltage range??..
And since the electricity board has clarified that no fluctuations in my locality- then
2. for the wielding - how much voltage may Up / down. Since I do not have idea about AC Stabilizer -
3. please recommend ( if really required) the voltage stabilizer that I wud need & how it will protect my AC..

>> 4.
ALSO, i HAVE LEARNT FROM SOME ONLINE SITES -THAT a Voltage Stabilizer will consume more (~5%) electricity. Is it true..

32
Abhishek Jain (Mod)

Voltage stabilizers have 2-3% electricity losses. So not 5% but about 2-3% for sure. You will have to contact Carrier to know the operating voltage range. It may also be mentioned in the user manual that you would have got. I am not aware of it. Also, I also do not have any idea on how much would be the voltage fluctuations due to welding.

33

Hi Abhishek,

#1: In both 1st & 2nd floor - my Balcony is partially closed & partially grilled - so it is not entirely a closed locked area..
Considering that Should the carrier cyclojet Outdoor unit be ideally placed inside / outside only??
My only apprehension is that if the Outdoor unit (whose top is open) is placed out - it will be continuously be exposed to sun / rain / dust - Will that not be a problem?? Keeping in mind the longevity of the AC outdoor unit performance, what will be your suggestion - inside / outside??

#2: Will the power connection setup for the AC fall under the standard installation by the service Engg . / I have to do it separately by calling an Electrician?? And in case of an electrician, any specifications to be mentioned to him??

#3: Is the wrapping up of the pipe required?? - in the shop they were saying this will not fall under the free Standard installation & required Rs. 40 / feet..

#4: I checked with Goenka CESC - the electricity provider in Kolkata. They said this area don't have much voltage fluctuation. But the neighbors were telling me - during the welding process in the nearby small factories - the voltage fluctuates a bit..Please advise if I would require a Voltage stabilizer in this case??

34
Abhishek Jain (Mod)

Here is my response:

1) As long as your balcony has good ventilation (through the grills), it should be good enough to install the outdoor unit. The outdoor unit just needs space to throw out the hot air (and ventilation will ensure that the hot air will go out and will be replaced by cool air). The area around the outdoor unit SHOULD NOT GET HOT.

2) You will just need a 15 AMP plug point to connect the AC. That is all that is required. Any electrician can do that.

3) Wrapping of the pipe is required to keep the pipes well insulated. Else it will lose heat and your AC will consume more electricity.

4) Welding process does suck a lot of power and can cause voltage fluctuations. You can go for a voltage stabilizer (make sure that you go for one with surge protection or thermal overload protection).

35

Hi, I live in Mumbai. I want to purchase an 5 star inverter ac with I intend on using say around 8 hours a day.
From reading your posts I understand that I require 1.5 ton ac,a copper condenser since corrosion is part of life near sea/lakes. At times there are power switch offs and on by MSEB, so probably need a stabilizer?
I view nearly every invertor 5 star ac all reviews are negatives. Daikin (Jtkm50)seems to break down after months of operation, Samsung acs stink a lot, Hitachi 5300i and 5400i don't have good reveiws either, same with the Godrej GIG 18 Dgog.
1) Which are the best ac brands in India (considering long lasting and good service)
2) Do I go for separate stabilizer or inbuilt? Are LG, samsung, Daikin only acs with inbuilt stabilizer?
3) Which inverter 5 star ac would you suggest (price is not a constraint) for a copper, 1.5ton, (optional eco friendly refrigerant - say R290 or R32 or any other).

36
Abhishek Jain (Mod)

Hi Calum,

Here is my response:

1) As mentioned in the post above: Hitachi, Daikin, Mitsubishi (Heavy and Electric), O General, Blue Star, and additionally Panasonic, Carrier are great brands. Service varies from location to location, so you will have to get local feedback to know about service.

2) Inverter ACs do not get damaged due to low voltage. But power surges can surely damage the PCBs. I do not think MSEB has such a bad supply. Power quality in Mumbai is one of the best in India. I personally have a supply from Tata Power (and have used Reliance in past) and I have never ever used a voltage stabilizer for any of my appliances. Inverter ACs also have long operating voltage range. LG and Samsung have a huge voltage range. All others can still work on decent ranges. A voltage stabilizer is required for non-inverter AC if you have voltage fluctuations (I have a non-inverter AC in Mumbai and I do not use any stabilizer for it).

3) These are the most efficient models on Inverter ACs with copper condenser:

DAIKIN JTKM50
HITACHI RSA518CAEA
HITACHI RSB518IAEA
BLUESTAR 5CNHW18PAFU
BLUESTAR 5CNHW18DAFU
TOSHIBA RAS-18N3KCV-IN + RAS-18N3ACV-IN
VIDEOCON VSX57
BLUESTAR 5HNHW18PAFU
BLUESTAR 5CNHW18QATU

Out of these, Hitachi and Bluestar would have the best corrosion protection.

By the way, if you are near the sea (3-4 km from the sea). Then it will be better to avoid inverter AC as the inverter ACs have a PCB in the outdoor unit as well which gets damaged due to corrosion. And it is expensive to repair it in case of damage. Go for it only if you are away from the sea/lake.

37

Thanks for your fast and kind response.

Just a few more points to clarify on

1) No doubt the models that you have mentioned for good efficiency. But just concerned about a lot of negative reviews on 5 star inverters that I have read online whereas low efficiency inverter acs and non-inverter acs have better reviews. So just wondering if there any inherent problem with 5 star inverter?

2) Now, I live near 2 water bodies (say surface area of a cricket stadium) within a kilometer of my home. So consider I go in for a Hitachi or Blue star inverter, which you mention have better corrosion protection. Would you still give a go ahead to buy a Blue star/Hitachi inverter ac?

3) I particularly liked the Blue star 5CNHW18QATU since its efficient as well as greener in terms of refrigerant, and as you said better resistance to corrosiveness. I've checked on e commerce sites, company website and even in stores with no availability. Would you have any idea of its availability anywhere (any particular stores in Mumbai that you know of?).

4) Regarding a voltage stabilizer, I not sure about power surges but MSEB does have problem of short circuits especially during monsoon. Would that be a cause of concern for the inverter ac?

38
Abhishek Jain (Mod)

Here is my response:

1) Not sure where you saw negative reviews, most 5-star inverter ACs are not available online. And if you looked at Moutshut.com, then let me tell you that it is a website that asks for ransom from brands for doing a review. If a brand pays money, their own people put positive reviews, and if a brand does not pay, then they put negative reviews (on their own). The best sites to get real reviews are e-commerce sites and also look for reviews where there is authorised purchase. There is no reason for inherent issues in 5-star inverter ACs because the technology is similar as 3-star inverter ACs (it is just about using better materials and design).

2) I would suggest that you check with your neighbours if they have frequent corrosion issues with their ACs (gas leakage, etc). If they do, then go for a model with better corrosion protection. In fact, in that case, I would say avoid inverter ACs for now because inverter ACs have PCB in outdoor unit that can get damaged due to corrosion and it is expensive to repair. In that case, I would suggest that you go for Bluestar, Hitachi or Panasonic BEE 5 star rated non-inverter AC. But if it is not corrosive, then you can go for any BEE 5 star rated inverter AC. Bluestar and Hitachi will also be great.

3) All Bluestar inverter ACs have a copper condenser with bluefin corrosion protection. All the 3 5-star series have green refrigerant (all have R410A or R32). I am not sure where it will be available in Mumbai. You will have to check with authorised Bluestar dealers.

4) Short Circuits do not usually happen due to the power supply. They happen due to faults in your setup. During monsoons, power surges (sudden rush of current) can happen due to lightning falling on the wires (usually that happens when there are overhead wires). And if that happens, it will not just damage your appliances, but can damage appliances in all your neighbourhood. Surges can damage any appliance and not just inverter AC. Also as per my understanding, most of the distribution lines in Mumbai are underground, which should not get impacted by lightning as well. Well, whatever, if you really want to go for safety, you can go for a voltage stabilizer with surge protection or thermal overload protection to protect your AC. Having one will not cause any damage.

Thanks again for your reply.

Few more clarifications required

1) I was viewing the Bluestar Q series inverter ac on the company website. They mentioned an 2 options on the same ac of a) anti corrosion blue fin copper condenser with 1 year warranty, or b) long life MCHX condenser with 5 year warranty.
I always thought that the blue fin copper condenser is more durable but they are offering only a 1 year warranty on it, whereas the MCHX offers a 5 warranty. Which option is better and why?

2) I am willing to consider buying a 5 star star ac instead of a 5 star inverter ac. Few questions related to that. What would be the average difference between a 5 star non-inverter and a 5 star inverter ac in terms of efficiency.

3) Similarly, the difference in terms of possibility of corrosion in a 5 star non-inverter vs 5 star inverter. You mentioned of a PCB in the outdoor unit of the inverter ac. So does the non inverter ac not have a PCB?

40
Abhishek Jain (Mod)

Usually, more warranty is given on something that the manufacturer believes will work well but the customers have a doubt on the durability. Warranty is less on a thing on which customers do not have much doubt on.

Both copper and aluminium (MCHX) work well. The problem mostly happens only if the environment is highly corrosive. In terms of energy efficiency, MCHX is better, but in terms of maintenance, copper has some advantages (which become more prominent in a corrosive environment). I have personally used a model with MCHX for 8 long years without issues. But for some, it gives regular leakage and breakage. And with MCHX, any damage needs a complete change of the condenser whereas copper one can be repaired. In a corrosive environment, both can get damaged (as even copper is corrosive).

A good 5-star non-inverter AC would have EER of 3.7 and a good 5-star inverter AC would have ISEER of about 5 (both EER and ISEER are comparable). That is roughly 30-40% more energy efficient. As per BEE data a typical BEE 5 star rated 1.5 ton non inverter AC would consume about 1300-1400 units a year (for 1600 hrs of usage), while a BEE 5 star inverter AC would consume about 850 units. But these are numbers in ideal situation, in real world the consumption would vary based on situation (which is where inverter AC works better as it adjusts to the situation).

There is one PCB in the indoor unit of ALL ACs. Inverter Tech ACs additionally have one in the outdoor unit. In general feedback from corrosive areas is that it is possible that the PCB gets damaged in about 3 years. And the repair cost is about 15-16K. Non inverter ACs do not have PCB in outdoor unit.

41

Hi,

You had previously advised not to go for inverter ac as the outdoor unit has a PCB that can get corroded. In realtion to this, I was viewing the Godrej NXW 1.5ton inverter ac which has the R290 refrigerent. It specifications mentions golden fin copper and the PCB comes coated also also gives 10 year warranty on compressor and 5 years on condenser

You had previously suggested Blue Star and Hitachi as the best for corrosion protection which have the blue fin copper. How dpes the Godrej one compare to Blue star and Hitachi? Also what's the difference between blue fin and gold fin coating.

Thanks again

42
Abhishek Jain (Mod)

If you get 5 years warranty on a copper condenser then it is a great deal. R290 is the greenest refrigerant in the market. Gold Fin is also good for corrosion protection. Both blue and gold fin do not let water to stay on the condenser coil thus preventing corrosion. In terms of brand value Hitachi and Bluestar are more popular. But I would say Godrej is also good. You can certainly go for Godrej NXW model as it will be highly energy efficient as well as green.

43

Please tell which model is better for a room size of 120sqft from these two models
1,Panasonic 1.2 Tons AC White CS/CU-KC15SKY5R
2,Hitachi 1.2 Ton 5 Star ZUNOH 5200f -RAU514AWD

44
Abhishek Jain (Mod)

As far as brands are concerned, both Hitachi and Panasonic are good.

45
Abhishek Jain (Mod)

120 sq ft room in different cities will have a different requirement. I cannot confirm if 1.2 ton AC would be good enough for your room or not (you can check the same using the calculator on this page). In terms of cooling, both the models are equal. In terms of power consumption, Hitachi model would be better. Hitachi model is a more sensor rich model with optimized performance based on presence of people in the room. Whereas Panasonic model has better air filters for cleaning the air. It truly depends on what you want.

46

Thanks Abhishek for prompt response. I also checked online that 5 star inverter ACs are expensive. Will the higher spend justify (in terms of savings from electricity bill over the life of AC) given the fact my usage will be for almost 8 months in a year and each day for almost 14-15 hours. I want AC with longer life and low ownership cost. Some of the must have features that I am looking for are dehumidifier, air purifier, anti rust and anti corrosion.

47
Abhishek Jain (Mod)

Hi Jignesh,

For 3600 hrs usage in a year in Mumbai, it will certainly justify high costs. You will certainly lie in highest electricity tariff slab if you have so much AC consumption in mumbai. As compared to BEE 3 star non inverter AC, you can save at least Rs 10000 per year using a BEE 5 star inverter AC. You will get a BEE 3 star non inverter AC for about 26-27K and you can get a good BEE 5 star inverter AC from Bluestar for about 38K. All that cost will be recovered in a year or two. Even if you go for a slightly expensive one for about 45K, then also you can recover it in 2-3 years. If you want anti corrosion copper model, aith air purifier (dehumidification happens in every AC), then Bluestar and Panasonic ACs would be your best bet. Bluestar 5CNHW12PAFU or 5CNHW12DAFU and Panasonic TS12SKY all have the features that you are looking for.

48

Thank you Abhishek.

Are these models of 1 ton capacity? I went through website of bluestar. Came across various models under inverter technology and got confused (Precision inverter - P & D Series, Smart Inverter P series, Inverter Split - P & Q series) what is the difference in these? Which of these would be ideal for me considering the features i am looking for? Are these all BEE 5 Star Inverters?

Also, I came across a Daikin Model having ISEER rating of over 5 costing aroung 45K. Is the higher price only because of the energy rating of over 5 as compared to 4.71 of bluestar? Are there any other feature gaps between the two. I am asking because i have to zero in the brand first before i go for the models. Which is better - daikin or bluestar?

One last thing, I read somewhere that from 01.01.2018, new emission standards will come into effect as a result of which the newer ACs will be more environment friendly. What other differences will be there in those ACs? I guess the prices will also go higher in general for ACs since newer technology will be in place because of regulation. So it would be good if one buys ACs before that to save cost. What are your thoughts on this?

49
Abhishek Jain (Mod)

Hi Jignesh,

You are looking for a dehumidifier, air purifier, anti-rust and anti-corrosion which is there in all 3 series: P, Q and D from Bluestar. P Series is the most energy efficient (highest ISEER) or least electricity consuming but has a slightly lower cooling capacity (which will not matter much in your case). Q and D series have slightly higher cooling capacity range, but slightly less energy efficiency as compared to P series. And all 3 will have everything that you want (a dehumidifier, air purifier, anti-rust and anti-corrosion). There are some other features like D series has ionizer which is good for disinfecting air, it also has a compact design. Q series has powerful airflow to cover a longer area. I think D series will also be good for you (difference in electricity consumption is not much). These all are BEE 5 star inverter ACs.

Daikin model that you are looking at has ISEER of 5.8, which is the most energy efficient in the market. They also have Daikin's proprietary air purification technology built in. But Daikin JTKM does not have corrosion protection (it has a copper condenser, but this is not an anti-corrosion series from Daikin). Daikin is a leading Japanese brand whereas Bluestar is a premium Indian brand. Both brands are good.

From 1/1/18 new energy efficiency standards will come into effect (and not emission standard). ACs do not emit anything (other than water collected as part of dehumidification). They have refrigerant which can be eco-friendly or not. Their electricity consumption can be higher or lower. The BEE 5 star inverters currently available will remain as BEE 5 star as per new efficiency standards. I do not think prices will change with that. There will be no new technology for the same.

50

Thank You so much Abhishek for all your inputs. I think I can now zero in the model that I have to buy.

One more thing about the installation part. I have seen in many customer reviews that in the cases of online purchases, the technicians have fleeced the customers by charging very high installation fees and in some cases the service is also not upto the mark.

Hence, I am planning to call the authorised company technicians to install the AC and will fix up the installation price at the time of purchase itself so as to avoid any hassle later on.

What do u suggest? which option is better? Online purchase or from vendor showrooms/company authorised dealers (especially for the installation part)

51
Abhishek Jain (Mod)

Hi Jignesh,

I personally purchased one Hitachi AC from Flipkart and my AC was installed by Hitachi technicians. And they did not charge me more for it. Everyone has mixed experience in different cities. Difficult to comment on that.

52

I live in mumbai. Looking for 1 ton 5 star inverter AC. Budget is under 30000/-. Please suggest some good brands

53
Abhishek Jain (Mod)

Hi Jignesh,

I have not seen any 1 ton 5 star inverter AC in a budget of under 30000. At around 30000 at best you can get is BEE 3 star 1 ton inverter AC.

54

Hi Abhishek,

Today ordered 2 AC from the 'Great Eastern Electronics' shop.. As per your expert advise & some Online research I went for 1.5 Ton/ 3 star Carrier Superia Cyclojet AC ( Same model For both the 1st & 2nd floor).. It costed 36K each.

Now, the purchase part is done...Some quieries re: the ac installation

1. Is voltage stabilizier reqd for this AC in both the floors??
2. I have balcony adjacent to both the rooms where I will keep my AC. So should the cyclojet outdoor unit be ideally placed in the indoor balcony to prevent rain OR at the outside?? Please advice
3. Any specifc advice re: the outdoor unit location / installation
4. Any specific things reqd by me before / during the installation process by service engg..

The installation will be made next week (around 28th Nov)

55
Abhishek Jain (Mod)

Here is my response:

1) For non inverter AC, it is better to have a voltage stabilizer (especially if there are voltage fluctuations). A lot depends on the power quality in your area. In Mumbai we have really good power supply without any fluctuations and thus we do not buy Voltage stabilizer. But if you have voltage fluctuations, then you must buy voltage stabilizer.

2) A close space is not good for an outdoor unit. It should be placed in an open space. So it should be kept outside.

3) Well the outdoor unit needs good open space where it can release heat. If there is lot of heat around the outdoor unit, it stops working well. So you should make sure that it has good air circulation so that it can release heat outside. Also while installation make sure that the gas pressure is checked, pipes are vaccumed before connection.

56

Hi Abhishek,

HAPPY DIWALI...

#1: Today, I went to the shop & enquired for 'Carrier SUPERIA ac'. The cost they are quotong is 40,800
BUt they are saying the outdoor is a Cyclojet tech Cylindrical model. I saw it & I am very confused -
because the top part is OPEN - Rain water , insects , dust may easily fall in that. Will that not be a big problem??
As per the salesman, the cyclojet will give terrific performance - bt from the first look of it - I am not confident..
Pleas advise - 'Carrier cyclojet superia' is it a good buy & i wont have any issues with the Cylindrical open outdoor unit in the long run??

#2: Voltas - 1.5 T/ 5 star - copper - their festive price is 39,500..It is just 1K less than the Carrier superia u suggested - so is it worth / should I go for the Carrier one only mentioned above @ 40,800??

#3: Another point is: Vestar 1.5T 5 star - they are quoting it at 36,000..( LOwest among its peers!!!)
But they are insisting its a new player in the market & they are not sure about its performance..
What u suggest - should I go for it as it is a 1.5 T / 5 star / copper - in the lowest price range?? Or i should not opt for it

>>>Considering the above experience at 'Great Eastern Shop', please suggest me to finalize the correct combination so that I can have the perfect buy @ DIWALI..

57
Abhishek Jain (Mod)

Rain water, dust and insects fall in any and every outdoor units. I do not see that as a big problem for cyclojet. Superia is a good unit and Carrier is a fantastic brand. Now cyclojet was launched just this year, so there is no long term feedback for the same. Although I do not see any issues with it technically, but I cannot say how it will perform in long term.

Voltas is also a good brand and if it gives you more confidence then I must say that you should go for it. One must always go with their own gut feel and if Voltas gives you comfort, then so be it.

Vestar is certainly new and has significantly low marketshare. I would say better go for Voltas.

58

Thanx for d advice..

So, for Voltas & Carrier - the ones listed down by you below in your comments:

Carrier - Superia

Voltas - 125 CYe / 125 CYu / 125LYd

>> This will be the best models right??..
What will be the approx cost estimate of these ACs currently??

59
Abhishek Jain (Mod)

These are 1 ton ACs from Voltas. As per your last message, your room is 12x12x12 which needs 1.5 ton AC. So you will have to select 1.5 ton models. Same 125 CYe would be 185 CYe and 125 CYu will be 185 CYu for 1.5 ton.

60

Thanx for the Response Abhishek. So which among the following wud u suggest as the best combination TO BE FINALIZED:

1. Voltas - 1st flr // Vestar - 2nd floor
2. Voltas - 1st flr // LG - 2nd floor
3. Voltas - 1st flr // Carrier - 2nd floor

OR any other combination that comes to your head. I am eyeing a Diwali buy in..So please suggest me the best combination for my home ASAP.

61
Abhishek Jain (Mod)

From quality and durability perspective, I would say 3rd one. But you have to choose a good model from these.

62

#1: Room size is 12*12*12 - it was a type error from me. As I saw from the AC Calculator in the site - 1.5 ton will be reqd- are u suggesting 1T / 1.5 T for 12*12 rooms??

#2: Any other brands within 40K budget that you would like to recommend - or the Voltas / Vestar is the best choice in that zone & as per my Req??

#3: Is Vestar & OGeneral the same company??

63
Abhishek Jain (Mod)

#1 I suggested 1T for a 10x10 room and not for a 12x12 room. You had mentioned 10x10 as the room size and that is why the suggestion. And in fact for 12x12x12 room on the top floor you need 1.8 tons of cooling and a 1.5 ton will not be able to cool the whole room. And 1.5 ton will be required for the room on lower floor.

#2 I gave you Voltas and Vestar because you asked for it. We usually do not recommend just brands, we look at a person's requirement and recommend energy efficient models that fit in those requirements. And those two brands were part of your requirements because you had mentioned: "I have selected Voltas and Vestar". Also we do not have location specific data to suggest if a brand is good in a city or not. We usually depend on the person for the same. You will have to gather information from local dealers and users of the brand to figure out which one is good and which one is not in your city. I can suggest you the most energy efficient (electricity saving) models in your budget. These are some models from Premium/Popular brands that are energy efficient and will fit in your budget as well:

My main criteria would be -
1. Sustained performance with minimal servicing Required
2. Energy efficiency - Bill Bachao should be an inherent feature
3. Good after sales service in my area
Please provide your valued advise ASAP.

65
Abhishek Jain (Mod)

By the way if you are in slight corrosive area (close to sea or any water body), then I would suggest that you go for Vestar models because Vestar is a brand owned by OGeneral and they mostly make all copper ACs which are good in general if the environment is corrosive. Voltas mostly has Aluminium models with only some models in Copper. Aluminium is good in general, but is not recommended in case the area is corrosive.

66

I stay in Kolkata. I wud buy 2 ACs. One is ground floor & 2nd one in the top floor..Room size is 10* 10 * 10
Duration of use: 8 months - 5-6 hrs / day - Not a heavy usage
Please advise - budget of 30 - 38K..
I have selected Voltas & Vestar - 1.5 Ton / 5 star AC..
Please suggest the best as per my Requirement.

67
Abhishek Jain (Mod)

If Bijli Bachao is your criterion, then DO NOT go for a 1.5 ton AC as both your rooms would be absolutely fine with 1 ton AC. A 1.5 ton BEE 5 star would be as good as a BEE 3 star or less because it will be oversized. You can go for Voltas BEE 5 star rated 1 ton AC. You can check these:

2) SPLIT AC - 1.0TR HITACHI WAZA 4200i INVERTER - R410A - RSG412EAEA

Can you plz. help with the link if you are aware as to which e-commerce sites sells the above models....!!

Abhishek Jain (Mod)

Because BEE 4 and 5 star rated models are a bit expensive, I usually do not find them on ecommerce platforms. However, Daikin FTKP is available online: Amazon link: http://amzn.to/2gkyY8M ... also at about the same price, you can also get this BEE 5 star rated AC from Bluestar which is also a great model: http://amzn.to/2ykvL05

70

As you said.... Data is sorted by ISEER. Hitachi RSG412EAEA is the most energy efficient.

But leaving aside ISEER..... In terms of Durability.... Performance.... Price.... After Sales Service... ROI..... Which is better and the best out of this 4.

1) HITACHI KASHIKOI 4200i INVERTER - RSE412AAEA
2) HITACHI WAZA 4200i INVERTER - RSG412EAEA

77
Abhishek Jain (Mod)

My guess is that you will need a 1 ton Inverter AC, but you can check the same using the calculator on this page. I usually do not run the calculator myself because it takes time and there are too many questions to respond to. The calculator has been created so that users can do their calculations themselves (as otherwise there will be too much back and forth to get all the details).

Now Daikin does not use R410A and it uses R32 (which is also good). But if you want good corrosion protection then you will have to go for Hitachi, Bluestar, and Panasonic. Also LG has really good ACs but they use Aluminium alloy for their condensers (they do have some copper models but then they are BEE 3 star rated). Although I think for your usage BEE 3 star rated inverter AC would be good enough, but if it fits in your budget, you can go for BEE 4 star rated AC as well.

You can look at any of these:

Thanks for your explanation Abhishek.

As you said top 3 in the list are BEE 4 star i.e. HITACHI RSG412EAEA, DAIKIN FTKP35 and DAIKIN JTKPP35..... Are this the latest models and what is the difference between DAIKIN FTKP35 and DAIKIN JTKPP35 ?

79
Abhishek Jain (Mod)

These are the latest models. FTKP35 although has been going on since some time but every year they certainly do some modifications. Like this year FTKP35 has PM2.5 filter (which was not there last year). JTKPP35 is their new Anti Pollution series which has steamer discharge technology to clean the air. From an energy efficiency point of view, they are the same.

80

Thanks for all the clarifications Abhishek.

Last but not the least.... Out of HITACHI RSG412EAEA, DAIKIN FTKP35 and DAIKIN JTKPP35..... which is the best as per my requirement ........ in terms of power saving being the most important cause in Mumbai 1 Unit is almost Rs 11 and above.... latest technology (features).... durable.... and should not have any regrets later for investing good amount in AC.

Thanks
Cyril Fernandes

81
Abhishek Jain (Mod)

The data is sorted by iseer. Hitachi RSG412EAEA is the most energy efficient.

82

Thanks Abhishek...!!

Thanks for your suggestion.... I required 1 ton AC..... Just inquisitive to know that you have not included any Voltas models in the above .... Aren't they good ? Also they have 100% copper coil.... Right ??? How is " Voltas All Star Inverter AC "..... Which is the best 1 ton model which will suite my requirement.?

83
Abhishek Jain (Mod)

Each BEE star rating is a range of ISEER and Voltas is usually at the bottom end of each (so its models usually barely qualify for a star rating). Also they only have BEE 3 and 5 star models (no 4 star). Their BEE 3 star inverter model has ISEER of 3.6 and their BEE 5 star models have ISEER of 4.6. Not all of their models are 100% copper. They have a mix of alluminium alloy and copper. I just tried to find the models that have a decent ISEER (above 3.7) and are BEE 3 or 4 star. And that is why Voltas did not come up.

I would say all the models that I have mentioned with suite your requirement. You can choose one based on your brand preference. I would say the top three in the list are BEE 4 star. Any of them would be fantastic.

84

Thanks Abhishek.

What is the difference between "HITACHI KASHIKOI 4200i INVERTER - RSE412AAEA" and "HITACHI WAZA 4200i INVERTER - RSG412EAEA" ? Is there a major difference in terms of technology or are they same ?

85
Abhishek Jain (Mod)

Kashikoi is a more sensor rich version. It has sensors that optimize performance by sensing human presence or movement. It also has stainless steel coated filter. Waza is a basic version. So in hitachi all models in a star rating have same efficiency, they only differ in features. Kashikois are sensor rich versions, Neos are the 2nd best and Wazas are the basic version. But if you are not interested in features then the basic version will have same electricity consumption.

86

Ya..... Just read through all the features on the website..... Just inquisitive to know.... Does this features for e.g. i-clean, Stainless Steel Coated Filter, Auto Filter Cleaning Indicator, Wave Blade T-Flow Fan, 4 way swing..... really work in real conditions ??

Do I really require this features ?? or as you said that Basic Waze 4200i will suffice my requirement.

87
Abhishek Jain (Mod)

In your requirement you mentioned: "good ISEER..... Power Saving..... Durable.... Blue Fin (Copper) Technology..... R410A Refrigerant" ..... which is there in basic Waze 4200i as well. Those features are not part of your requirements but additional. It depends if you need them or not.

Hello Abhishek Sir,

I am planing to buy 2 AC for my Home, Need your Suggestion.

I live in Mumbai, on the 10th floor, I have 2 rooms, 1 small bedroom (84 sq feet) and 2nd (128 sq feet).

1) Uses 8 Hours daily 8 Months
2) In my area lot of dust is ther.
3) For 2 AC my budget is 60 K.
4) Low maintenance & Good Customer service is my priority.

89
Abhishek Jain (Mod)

Hi Prashant,

Ideally a 0.75 ton AC is good for smaller room and 1 ton AC for the bigger room (assuming you are not on top floor). Your usage is high so going for inverter tech AC would be better. The 0.75 ton inverter tech ACs are few in market and they are expensive. So you can also go for 1 ton inverter AC for the 84 sq ft room (although 0.75 ton would have been better). You can get some options in 1 ton inverter AC in a budget of 30K, but then your will not get the ones with good air filters or auto clean technology (for the dust). You can check models from LG, Samsung, Whirlpool or even Mitashi and Sansui (although LG/Samsung and Whirlpool will have better service) on Flipkart: http://fkrt.it/Zw0dhTuuuN or Amazon: http://amzn.to/2wH81yS

This is quite strange because any AC consumes lesser electricity at higher temperature. So at 26 it should consume less and not more than when you set it at 24. And 7-8 units in 10 hrs for a 5 star rated inverter AC is unacceptable. Something is wrong either in AC or in the way evaluation is done.

92

Service engineer visited once again and told me at night outer temp falls and reaches to 25 if i set thermostat at 27 then ac not work efficiently this is reason of higher unit consumption so he advice me to set at 23-24 thermostat..
Plzz guide me

93
Abhishek Jain (Mod)

Hi Manish,

If outside temperature is 25 and you keep thermostat at 27 then there is no heat to remove and the compressor should not work at all. In that case the compressor should not start and your electricity consumption should be further lower. Whenever they give any such reason, ask them to give it in writing. They are all giving weird reasons.

I usually keep my own AC at 27-28 most of the time and the temperature outside goes down several times. My Panasonic inverter AC shows me compressor speed in % (120%,100%,80%,60%,40%,20% and 0%), and at all such times I have observed that my AC compressor speed is 0%.

94

The technician visited told me that any ac works perfectly below 25 ... he also adviced me to operate it between 22-24 degree

But according to u and ur site, team run air conditioner at higher thermostat is beneficial

I am confused to understand

95
Abhishek Jain (Mod)

Hi Manish,

You will have to trust someone to remove confusion. 22-24 is not the ideal temperature. I personally run my AC at 27 and it hardly consumes any electricity.

96

Then what should i do next to it...
The service engineer also provide me a cell no. of regional service head he also told me same thing they are not accepting about any fault in ac

97
Abhishek Jain (Mod)

Difficult question as unfortunately I do not have any answer for that. I can tell you how it should work technically but that is the best that I can do.

98

How i explain fault to their higher authority

99
Abhishek Jain (Mod)

Ask them to give in writing that it will consume more electricity at 27 than at 22.

100
Abhishek Jain (Mod)

Even if you star counting from 35 downwards you will take less time and effort to come to 27 than going down to 22. I am trying to explain this to you in very layman terms. But this is how it is.

101
Abhishek Jain (Mod)

You can simply say that to bring down the temperature from 35 to 27, the effort required is less because you are trying to remove less heat. Then how can be input power be more a compared to bringing down the temperature from 35 to 22. It is very logical.

102

Hii abhishek
Today technicians team come again and the service the whole machine and they have a ampere machine in which they shows me load 3.2-3.6 ampere ..
Is 3.2-3.6 load at 26.5 temp for a 5 star inverter ac is normal or not???

103
Abhishek Jain (Mod)

Hi Manish,

3.6 Amp is about 800 Watts, which is great for a 1.5 ton inverter AC. It may reduce after some time after the temperature stabilizes.

104

And i calculated these data or units exactly for 5-6 days at different temp.....
The data of unit i told u is exactly true and real

105
Abhishek Jain (Mod)

What will take more energy? lifting 5 kg weight or lifting 10 kg weight? Of course lifting 10 kg weight.

Now AC's job is to take out heat from the room and throw it out. Temperature outside is 35 and you plan to keep it at 27. The difference between the two is 35-27 = 8 degrees. But when you keep it at 22 the difference is 35-22 = 13 degrees. Heat to be taken out is less when you keep it at 27 and more when you keep it at 22.

What do you think will take more energy (or electricity) cooling by 8 degrees or cooling by 13 degrees?

106

Hii abhishek
Thanks for reply
3.6 amp is after stablizatn its not at beginning its after achieving set temp 28
3.6 amp at 28 after stabilisation room size 140sqf atmospheric temp about 33 persons in room 4 these are stat
Plzz analysis the data..and tell me is it good for 5 star inverter 1.5 ton
And plss also tell how much consumption at this rate ( in unit)

107
Abhishek Jain (Mod)

Do you really have 33 people in the room? If yes, then 1.5 ton AC would be really small for it. Each person emits body heat and that will put a lot of load on the AC. And in that case your purchase is not right. Also which city are you in?

108

I am worried because its a replaced unit means earlier i have 5cnhw18pafu but its have compressor problems then they replaced the unit but they have no D model so they rplaced D WITH P model within warranty period
I have doubt about its 5 star inverter capability means 3star invt in 5 star invt body

109
Abhishek Jain (Mod)

If your purchase is right then 5 star inverter will give 5 star performance. But if you purchase is not right then it will certainly not perform. For e.g. if you have 20 people to travel then you cannot assume that a sedan car can easily carry all the passengers just because it is a sedan and is a big car. A sedan can only take 5 people and max 6-7 if you stuff people in. But not 20 people.

110

Outer atmospheric temp is 35-36

111

Hii abhishek
No abhishek how can 33 people sit in 140 sqf 33 is outer temp peoples are only 5

112
Abhishek Jain (Mod)

Hi Manish,

3.6 Amp running current is about 800 watts. Which means it would consume 7-8 units in 10 hrs of running. My assumption is that it should have come down to about 500-600 watts in steady state for a BEE 5 star rated AC (as per Bluestar manual the 50% load wattage is about 530). Somewhere there is problem. You should also ask them to check the wattage using wattmeter. The performance is better than a non inverter AC (even that of a regular BEE 5 star non inverter), but then it needs to be slighltly better for a BEE 5 star rated inverter AC.

113

Sir, thanks for your inputs to my previous queries of 25-9-2017. The Daikin FTC 42 (s series) , 1.2 ton, 3 star's split
a c, which I had ordered will be delivered next week. Also as per your suggestion, I have already purchased the V-Guard V G 400 stabilizer. My present query is ....is a MCB / ELCB necessary / compulsory for this a c,, even after connecting the stabilizer ? Am having 3 phase connection and in our area, much fluctuations do not happen., but power trips off sometimes. If it is necessary, which brand could you suggest. Kindly advice.

114
Abhishek Jain (Mod)

It is not compulsary to put MCB or ELCB for this AC.

115

Hello Sir,

Great work you provide valuable information about Air conditioners.
Please guide me for buying 1.5 ton inverter ac with copper condenser, 3 or 4 star and also with rust protection as I live near a river.
How about diakin JTKP35SRV16E as it's the only product in diakin that provides Anti rust coating or any other product that you would recommend in Hitachi .
Thanks.

116
Abhishek Jain (Mod)

Hi Anupam,

The best corrosion protection is available in brands like Panasonic, Bluestar and Hitachi. They all have copper models with blue fin coating. You can look at any of these:

Also JTKP35 is also a good model. You can go for that as well. It is a BEE 4 star model. In the list above Hitachi RSG412EAEA and Panasonic KS12SKY are BEE 4 star.

117

Hello Abhishek,

Thanks for your prompt reply, it's really very nice that you take pain to reply everyone personally.

I am living near a river although not that big, earlier I was planning to buy inverter ac but as suggested by you to someone to go for fixed speed ac I also decided for the same.

Please help me out in choosing the best one.

I am interested in diakin ac as services of Hitachi as heard is not that good.
So please tell me about Anti corrosion 5 star diakin ac(non Inverter).

Also how about blue star ac as brand , are they equally effective to diakin or Hitachi quality, efficiency, durability wise. In blue star which 5 star non Inverter AC would you suggest.
Thanks.

118
Abhishek Jain (Mod)

Hi Anupam,

Daikin's FTF/ATF/DTF series are good, but I doubt if they have good corrosion protection. Bluestar is a premium Indian brand. It is quite good and even Panasonic is quite good. I have given you the list of 5 star non inverter ACs from these brands that are good in my previous message.

119

Thank you very much Mr Jain. Now, I am not comfortable with my choice. I would request "mydaikinstore.com" or [email protected] for a change in model. If my request is accepted, then which model of daikin should I go for, suitable for both my rooms. My usage would be 8 hrs per day for about 3 months in summer only.
The a c I ordered is having MRP Rs35,700/-, but got it for Rs 30,600/-. I could go upto Rs 33,000/- for a more suitable model on your suggestion. That is if my request for a change is accepted. Kindly suggest a more better daikin suitable for my needs, upto Rs 33,000/-
Thank you once again and would request for an early reply.

120
Abhishek Jain (Mod)

Hello Mrs Dastoor,

I doubt you can get more energy efficient AC in a budget of 33K from Daikin. I think this is the best model in your budget. You can continue with it as your usage is only for 3 months.

121

Dear Sir, I am from Secunderabad and my bedroom room size is 10ft x12feet, east facing, 1st floor, in three story building, getting sunshine from morning to approx 11.30a m, after which no direct sun full day, as other rooms are facing west, and both sides having other flats. I have booked a non-invertor Daikin FTC42(s series),1.2 ton,3 star split a c.
(a) Pl let me know if I need an voltage stabilizer (specification ?) as am not clear from company specifications, and also if I need a 5 amps or 15 amps elec connection.
(b) If needed, can I use it for the other bedroom of 12 ft x 15 ft ????, sunshine from 12.30p m to sunset.
(c)Does this a c need water connection ???
What is your opinion for this model a c.
Thanks.

122
Abhishek Jain (Mod)

Hello Mrs Dastoor,

10x12 room in your house needs 1 ton cooling and 12x15 room needs 1.5 ton cooling. Daikin FTC series is a BEE 3 star rated series. It is their least energy efficient series. A lot will depend on your usage of AC. If usage is less then choice is fine. But if usage is high then you may incur a lot in electricity bills. Also it is slight oversized for 10x12 room and undersized for 12x15 room. From an electricity consumption point of view, it will be better to use it in 12x15 room as slight undersizing is still fine. To answer your questions:

1) You certainly need a stabilizer for this AC. Choice will depend on how low your voltage goes. If the fluctuation is not much then Vugard VG400 (Amazon Link: http://amzn.to/2ksUXYz , Flipkart Link: http://fkrt.it/6BVDz!NNNN ) will also be sufficient.

2) You can certainly shift it to 12x15 room. It will be slight undersized, but still fine.

3) No AC needs water connection. ACs remove humidity from the room, so they throw out water, but they do not need water to operate.

123

Hi, I want to buy cost/energy efficient windows AC for my 12*10 room. currently i live in gurgaon . pl suggest which brand/model i have to choose. i'm planning to buy this diwali if discount will be there?

124
Abhishek Jain (Mod)

Hi Vishnu,

If you want to buy an energy efficient AC and you are worried about electricity costs, then I would suggest you not to buy Window AC. What is your budget for the AC? Is your flat on top floor?

125

I live in kanpur....room size 12.5*9.5*10.5 top floor direct heat from sun one window on east side...sunlight came through it. I think 1.5 ton will be good ????
I work from home so 8 month (summer) i will use it in day time for 9hr per day.

1- my budget 46k(+-) which 5 star ac should you advice.
2- some ac techniciens told me not to buy inverter ac as they are costly in maintenance. I dont want to waste money in maintenace of pcb board.
One nallah flows 1km away from my house.
3- please advice some power efficient ac...please mention how much unit of electricity they use in 1 hour.
4- how much 5 star hitachi window ac will consume electricity in one hour.
I want ac which require less service and breakdown.
Thanks

126
Abhishek Jain (Mod)

Hi Utkarsh,

1.5 ton would be good for you. If there is a nallah close to your house then better go for BEE 5 star rated AC. Also go for one with better corrosion protection (something like Bluestar, Hitachi or Panasonic). Please do not go for Window ACs as you will not get any energy efficient option in window ACs. You can look at these:

I have seen that drain today it is only 2 feet and have flowing water...is it good to have inverter ac because i use it for 8 to 10 hrs in day time.

What are options in 48k budget

128
Abhishek Jain (Mod)

Hi Utkarsh,

With a Nalla closeby, there is always a risk element associated as a lot depends on the quality of water in it. I would say going for BEE 5 star non inverter is safe. You can go through the list I sent you earlier.

129

Thanks abhishek

130

Abhishek, i am looking for a higher capacity ac (preferably 2-3tons) as our room size is bigger, on top of that our ceiling is a terrace which is exposed to sunlight all day long and gets heated up to tremendous extent. Which ac would you prefer? with or without inverter?

131
Abhishek Jain (Mod)

Hi Kaustubh,

Which city are you in? and what is the room size? Also what is your budget for this AC?

132

I am from Mumbai, my bedroom size is 30ft*18ft*10ft (L*B*H)
as of now i don't have any specific budget. I am open to whatever the cost is also if you can suggest a used one if at all in case there is any!

133
Abhishek Jain (Mod)

Hi Kaustubh,

You would need about 4.5 tons of cooling for your room. You will have to go for 2 ACs as one AC would not suffice. At best 1 AC will give local cooling in the area close to the AC. Points in the room farthest from the AC will not feel comfortable. An AC with high air flow rate can at best cover a larger area, but then heat from the top will not let it be comfortable farther away from the AC.

However, in terms of electricity consumption, it will be better if you go for a single AC. Because two ACs will certainly increase electricity consumption, even if both are inverter tech AC. You can check Mitsubishi Heavy Insudtries SRK25CSS-S6 (Link: http://www.iaplgroup.com/srk20css-s6_srk25css-s6.php ) .... they claim that their 2.2 ton AC can cover up to 450 sq ft. But then heat from your ceiling will also play a role and thus it will not be able to cover 450 sq ft.

If you want perfectly comfortable environment in the whole room, you can look at 2.2 ton inverter AC from Daikin. You will have to go for two of them as the room is huge.

134

Thanks Abhishek, appreciate your advice.

Dear Abhishek,

DAIKIN - FTKP50/DTKP50 - 43000

This the final price after multiple negotiation.

138
Abhishek Jain (Mod)

I hope you are not very close to the sea (about 3-4 kms from the beach).

139
Abhishek Jain (Mod)

DAIKIN – FTKP50/DTKP50 will be a better option as it is inverter AC. ASGA 18FTTA is non inverter and thus will not be as energy efficient.

140

Hi Abhsishek,
firstly thanks for all the efforts you are putting in. Need your expert advice on buying ACs -
- 2 Split AC - 1 for B/R & another drawing dinning
- bedroom has to be 1.5 tonne - usage will be high almost 15 hours in summer - what brand you suggest , budget appx 35- 38k
- drawing dining is around 15 ' X 19 ' , usage will be less here (appx 2-3 hrs daily) so should I buy single 2.0 tonne of 2 AC of 1.5 tonne will help , again what make and model you suggest ,
Also can you let me know if all split ACs come with copper tubes in box or we have to buy separately.
My flat is in Noida , nearby Delhi .

Thanks
Rahul

141
Abhishek Jain (Mod)

Hi Rahul,

As per my calculations, your drawing cum dining needs 2.5 tons of cooling in peak summers. If your usage is less then you can buy a single 2 ton AC and put it close to the seating area. It will not cool the whole room in peak summers, but will still make it quite comfortable. And the area close to the seating will be much more comfortable.

For the bedroom it will be better you go for a BEE 5 star rated AC with copper condenser and corrosion protection. In normal cases I would have recommended an inverter AC but then in Noida, corrosion problem is quite big and that is why I would suggest going for a regular BEE 5 star rated non inverter AC. You should prefer ACs from Panasonic or Bluestar as they have good corrosion protection along with good air filters. I do not have prices from Bluestar BEE 5 star ACs, but you can check these from panasonic (although bluestar has more energy efficient models):

Panasonic KC18RKY-1 (Flipkart Link: http://fkrt.it/AkSuRTuuuN )
Panasonic KC18SKY5M (Amazon Link: http://amzn.to/2gmsWEb )

Even in 2 ton you can go for either Panasonic or Bluestar.

142

Hi Abhishek,
Thanks for responding . I got another query -
- we are getting our interiors redone and want AC pipes to be covered inside wall , so that they are not visible outside.
- One of the mechanic told us that inside wall pipes may cause leakage and may cause issue in future.
So is it alright to get them done inside because overhead pipes doesn't look good aesthetically .

Thanks
Rahul

143
Abhishek Jain (Mod)

Hi Rahul,

It is not necessary that pipes with cause leakage inside the covering. However, there is always a possibility, may be due to corrosion or any other reason. And in that case you will have to open the covering to get them repaired. Try to see if you can get a covering made so that it can be easily opened in case any issue has to be detected. But in general this does not happen normally and can happen only in exceptional cases. A lot of people get the pipes covered.

144

I live in Assam receives more rainfall compared to most parts.
Is it may failure causes of Inverter ACs (PCB) by water corrosion?
Is there any way to prevent?

Is Samsung-AR18MV5HETR good or better as Samsung describe as below

[Stable performance
Keeps going in the most challenging environments with Triple Protector Plus technology. It prevents overloads, without a separate voltage stabiliser*, has an anti-corrosive coating, and can endure extreme heat.80V-450V ]

Or suggest a model for 1.5 T Inverter AC.

Thank you.

145
Abhishek Jain (Mod)

Usually rains do not cause that much of a problem. You can go for inverter AC. Samsung AR18MV5HETR is a great model. I can suggest another model only if you can specify your budget.

146

My budget around Rs.50,000 ± , if possible stablizer free like 130V - 300V.

Thank you.

147
Abhishek Jain (Mod)

Hi,

LG and Samsung are two brands that give best voltage range and voltage protection for ACs. I think that the samsung model you have chosen would be the best in your budget.

148

Hi Abhishek,
I need your advice for two bedrooms (approx 13*13 feet) and a large drawing room with size
i) one room gets very hot during summer, as a face of room is exposed to direct sunlight
ii) comparatively cooler than the first one
plan to use mostly during summers, with minimal use during other seasons
iii) drawing room is 24*15 excluding attached hallway and dining space
low maintenance is priority.
thanks

149
Abhishek Jain (Mod)

Hi Will,

To calculate the right size and to suggest you something, I need some more information. I would suggest that you use the AC sizing calculator on this page to calculate the right size for the ACs. The calculator takes in all parameters required to calculate right size. After the calculation let me know the size that it suggests along with your budget and I can suggest you some models.

150

Hi Abhishek,

I'm from New Delhi. Request your expert advice on my buying decision for a 1.5T / 5 star split ac (non-inverter). Models are Hitachi 518AVD, Daikin FTF50 & Voltas 185JY. Please feel free to advise any other model.

Do you advise to go for "heat pump" model like Voltas 18HYT?

Regards.

Sumit Banerji

151
Abhishek Jain (Mod)

Hi Sumit,

What is your budget for this AC? As for heat pump models, they are a good replacement of room heaters. But if you want to go for one, then go for one with inverter technology compressor. Non inverter Heat Pumps will not be very energy efficient and you will end up spending a lot on electricity bills.

152

Hi Abhishek,

I've picked up general recommendations (Hitachi & Daikin) that you've given on your site under cat. "1.5 ton split / 5 star" + recommendation from another site. I'm aware that your recommendations are in a different "price band". I'm not considering "inverter" option. Shall await your further comment.

Based on your advise, I'm ruling out "heat pump" option.

Best.

Hi Abhishek - I bought two units of Daikin Jtkm35 - after your valuable advise in last week. Should I get installation done from Dainkin or the dealer where I purchased? Dealer has ensuring me it wont void warranty and will handle any service issue in the warranty period. Dealer (Kalyan) is part of a moderate size electronic shops chain. Please advise and your views on it.

155
Abhishek Jain (Mod)

Better to get it installed by the brand.

156

Nowadays we see Split 1.5 Ton acs from brands like Micromax, kenstar and Hyundai available at around 22000 rupees. Your views on them sir. Thanks.

157
Abhishek Jain (Mod)

Many of them show very impressive energy efficiency numbers. But then derating is a factor which no one shows. Derating means that performance of AC degrades with time. Premium brands have low derating factor, which means the performance degradation is quite low. Whereas if the design is not so good, then derating will happen faster. I am not confident about derating factor of these brands.

158

Hi Abhishek - First up of all, Many thanks for providing such a comprehensive AC guide which provides complete information in Indian perspective.

I am planning to buy couple of AC units for bedroom, 1 ton each. Our usage would be typical as in your AC calculator. I am much conservative and hence sensitive about electricity consumption. I always prefer to invest more one time rather than higher recurring expenses for electricity consumption and maintenance. So, my choice for AC is Inverter AC, 5 Star with copper condensers. It may stretch my budget, but will provide energy efficient, durable product with low probability of repairing costs. After my research on internet and visiting dealers, my brand selection is Daikin (I would have loved to go with heavy duty O'General, but it do not provide BEE star rating in inverter models and service issues in our area, Titwala) & models choice is JTKM35SRV (5*) or ATKP35SRV (4*).

Now, one dealer is advised not to go for inverter models as it's outdoor unit equipped with a circuit board / ICs which are more prone to failure in case of power fluctuations compared to non-inverter ACs. Also repair cost of it very high around 17K. Is it a fact? please help.

Alos, most of the dealer suggested to go for non-inverter models for home usage. They would not inverter model as extra price is not justified for energy saving. I suspect, it has got commercial angle rather than hones advise for buyer. Please advise.

Thanks.

159
Abhishek Jain (Mod)

Hi Sandip,

Here are a few points:

1) Inverter ACs do have PCBs which can fail in case of power surges (not regular fluctuations but surges which are sudden high voltages). It can also fail due to corrosion if you live close to sea or water body like lake/nalla. They can be protected from surges using surge protectors (or voltage stabilizers with thermal overload protection). But corrosion is difficult to control, so if you live close to sea then I will not recommend going for inverter AC.

However, there are brands that have long voltage range of operation. For e.g LG and Samsung have models that can work between 90V and 450V. So most common fluctuations and surges cannot damage it. But still corrosion can damage it. For other brands you can put such voltage stabilizer that can handle big voltage range or a surge protector that can handle surges.

2) From an ROI perspective BEE 5 star rated inverter AC may not be viable for a regular home use (unless your usage at home itself is too high). In most general cases BEE 3 star rated is good enough. If you really care about consuming less electricity (for environment and the world) then you can certainly go for 4 or 5 star rated ACs as they certainly save more electricity (and may be in future, they may become viable with rising electricity costs).

3) Whenever you buy any appliance, you have to go for AMC and you cannot work without that. Usually AMC costs are about 10% of the product costs. So you will also find that AMCs of inverter ACs are higher just because they are bit more expensive as compared to regular ACs. However, pricing of BEE 3 star rated inverter ACs is closest to BEE 5 star rated non inverter ACs. And most (not all) BEE 3 star rated inverter ACs are slightly more efficient than BEE 5 star rated non inverter ACs and in general better to have (in terms of value for money).

4) As for the statement that 3 star has higher cooling capacity. There is no truth to that. Different models have different cooling capacities. You should look at your requirement and then find an AC that has cooling capacity close or more than that. 1 ton is equal to 3504 watts cooling capacity. So try to find an AC that gives close to 3504 watts output.

Finally in Titwala I think it is MSEDCL which supplies electricity. And MSEDCL supply is quite reliable with rare fluctuations and power cuts. In fact MSEDCL is quite close to MMR (Mumbai Metropolitan Region) in power supply. And I can tell you that I personally have inverter ACs and many of my friends have purchased inverter ACs (after talking to me). All are in Mumbai and I have not seen any of them fail (especially due to fluctuations). I have heard of cases due to corrosion but not much due to fluctuations in Mumbai. And I many of these ACs have almost given 4-5 years of service without any issue and lots of electricity savings.

160

Dear Abhishek - I deeply appreciate your detailed replay with very in depth analysis while answering my issues. Thanks a ton! It's really useful to make final buying decision. God bless you.

Abhishek Jain (Mod)

Hi Sandip,

Just one clarification (I guess my statement was a bit ambiguous) .... when I said: "In most general cases BEE 3 star rated is good enough. " I meant 3 star rated inverter AC .... and not 3 star rated non inverter AC. 3 star rated non inverter is actually the lowest in energy efficiency currently ..... but 3 star rated inverter AC is the most viable one.

Also, one of the dealer suggested that initial cooling capacity of higher star (4/5) model is not like 3 start model, is he right?

Hi Abi,

I was surfing I got AC Brand Concord Model 1.5 (Hot & Cold) R410a Copper is this is good product ? which comes near 32K is it good brand ?

I would suggest that you go for Carrier Superia. Concord does not have lot of presence and on top of that Hot and Cold may not be a wise choice.

Hi Abi,

Carrier 1.5 Ton Inverter (4 Star) Split AC - White

Hi Venkatesh,

I would suggest that you first properly calculate the right size of AC for your room because oversized non inverter ACs are not really good from electricity consumption point of view. A 120 sq ft room may not need a 1.5 ton AC. There is a calculator on this page that can help you calculate the right size.

Between Superia and Ester, I think Superia is a better range from Carrier. If you are planning for inverter AC then 1.5 ton may work fine because it can reduce its tonnage based on your room's requirement. In 35K if you can get Carrier Super Inverter AC then that would be the best. Otherwise LG BEE 3 star rated models are good on that budget.

Am confused between Carrier 1.5T superior inverter A.C. and Hitachi 1.5T 5400i RSa 518CAEA. Advise wrt cost implications as difference in rates in local market about 12000 pĺus service. I have Hitachi window but service is pathetic as handled by 3rd party. Is carrier handling their own service ?

Hi Nishant,

For home usage it is not necessary to buy the most energy efficient AC unless the usage is really high (about 2500 hrs a year and above). Carrier is a great brand and you can certainly go for Carrier Superia Inverter AC. In fact Service should be a very important criterion while selection an AC and if Hitachi is bad in your area then do not go for it.

Thanks Abhi. U have been very kind and helpful.
Just that I have another contender with Daikin JTKM50SRV16. Hitachi RSA518CAEA 2nd choice and Carrier is my 3rd choice.
1) What would you choose if budget is no constraints?
2) Daikin model says voltage range 130-265. So can this be used without voltage stabiliser ?
Daikin costing 1500rs less than Hitachi at about 47.5k wherein Carrier @ 45k.
Total running duration 10hrs a day 8 months a year.
Running cost of carrier is high I think.

Please if u can compare running costs of all three models.

Also if you can provide any updates on service quality of all three company in Ghaziabad Delhi NCR region.

Hi Nishant,

Here is my response:

1) I would choose Daikin JTKM50 if budget is not a constraint as it is the most efficient model and Daikin is a good brand.

2) Daikin model can be run without voltage stabilizer.

3) Operating costs cannot be compared without knowing the electricity costs in your city/on your bill.

4) We do not have data on service quality of various brands in different cities.

Hey Abhishek
Thanks for the help.
I have another query.

1) I have 5kv microtek main line stabilizer installed for full house.
My Home Meter is 3kv.
I generally have 3 fans along with 3 Led bulbs about 15watts, 49inch led tv 120watt and Hitachi Refrigerator 510litre 3 door.
Fridge running 24hrs; lights 6hrs and Fans in summer for 24hrs atleast 2 fans.
Now can I run 1x1.5tonne A.C. on the same 5kv mains Stabilizer along with daily run of IFB 2200 front load washing machine running daily once a day may coincide with A.C. running time.
In winter instead of A.C. geyser will be running.

Or should I install separate stabilizer for A.C.

2) There is a nullah(Drain stream) about 500m from my house. How will it affect my AC. The A.C. technician has advised some kind of spray on condenser and lines to protect them from early corrosion.

172

Hi Nishant,

Here is my response:

1) If you go for an inverter AC then 5 kV inverter should be able to run it along with a front loading washing machine. However, it will not work along with a geyser.

2) Having a drain is quite risky for an inverter tech AC. It has PCB in the outdoor unit which is expensive and prone to corrosion. Has your technician recommended spray for PCB? Because along with condenser, in case of inverter tech AC, PCB is also at risk. And replacing a PCB is expensive.

How would you say
Hitachi 1 Ton Inverter 6.1 ISEER (5 Star) Split AC - White (RSB/CSB/ESB-512AAEA, Copper Condenser)
Is ?
would it be better than godrej 1 ton(5 Star) inverter 5.8 iseer
because Hitachi has Copper condenser and Godrej has Aluminium Condenser ?

174
Abhishek Jain (Mod)

Hitachi is a better brand, so yes, I would recommend Hitachi RSB512IAEA.
