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

By on May 24, 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 Air Conditioners (AC) brand 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 Ten Energy Efficient Window Air Conditioners 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.

Please suggest the best split ac option for Mumbai climate to choose between the three inverter ac brands in 1.5 ton & 1 ton. Daikin /Carrier/Hitachi with the samilar star ratings. (Price of these brands are almost similar 5 star for 1.5T are around 42-44,000/- & for 1T around 33-35000/-), Also my ac usage in summer are 7-8 hours in the night & may be 2-3 hours in the day time. Other seasons only 6-7 hours in the night. No ac usage during the rainy season and in winters. Hope inverter AC would be justified for my usage. Also you may suggest any alternative good product comparable to the aforesaid brands with similar features and around the same price.

Abhishek Jain (Mod)

In Mumbai the last slab (which is over monthly usage of 500 units) is Rs 11 per unit. Even the next slab is Rs 9 per unit. Your usage of AC is 11 hrs per day in summer (4 months) so that totals up to 1200-1300 hrs and additionally in other months, so total would go upto 1600 hrs or more. In such case I would strongly recommend going for Inverter Tech AC (not the BEE 5 star one but BEE 3 star one would be good enough). Also I doubt that you can get BEE 5 star rated inverter ACs from the brands you have mentioned in prices that you have mentioned. At best you can get BEE 5 star rated non inverter AC in that price range. Even the better BEE 3 star rated models may barely fit into that budget.

But here is the comparison of energy efficiency of these 3 brands in different star rating buckets:

In BEE 5 star rated inverter AC you will find that Daikin and Hitachi would have the most energy efficient models. No other brand is same as them in BEE 5 star. Next best would be Blue Star.

In BEE 4 star rated inverter AC you will not find Hitachi (somehow they only make 3 and 5 star which is typical market norm). Carrier and Daikin both have good BEE 4 star rated inverter ACs. Decently good in energy efficiency.

In BEE 3 star rated inverter AC again you will find Hitachi at top. They have the most efficient BEE 3 star rated inverter AC. Daikin surprisingly does not have a great BEE 3 star rated model. Carrier again surprisingly does not have a BEE 3 star rated inverter AC.

So I think the best bet for you is to go for Hitachi BEE 3 star rated inverter AC. I think Hitachi RSH318EAEA (Amazon Link: http://amzn.to/2oDyR7E ) would be the best for you. In 1 ton your can look at Hitachi RSG312EAEA.

Dear Sir, which is the best ac for commercial use? Various shopkeeper says that inverter ac is not good for shop etc, because door of shop open frequently. They says non inverter is best for shops etc commercial use. Can you suggest me the best ac for commercial use.

4
Abhishek Jain (Mod)

Opening of the door frequently will increase the load on the AC. If you go for a bigger inverter AC (for e.g. your shop needs 1.5 ton and you go for 2 ton) then it would be perfectly fine. But if your shop needs 1.5 ton and you go for 1.5 ton and the door opens frequently, then it would not be good.

Hello Sir,
How do you rate these two models of bluestar 3cnhw18tafu and 5cnhw18pafu.is 3cnhw18tafu updated version of 3cnhw18cafu? . For tafu EER is more and annual power consumption is less than cafu.But the power consumption of 3cnhw18tafu is 1870 and cafu is 1760 so will tafu consume more electricity?.i heard many complaints that bluestar ac make very loud noise.what can i do to shade my outdoor unit other than covering with plants.

6
Abhishek Jain (Mod)

Hi Harsh,

In inverter ACs there is a range of cooling capacity and there is range of power. For 3cnhw18tafu the range of cooling capacity is 5190 (1204-5242) and power consumption is 1870 (303-1895). For 3cnhw18cafu it is 5135 (800-6500) cooling capacity and 1769 (330-2200) power consumption. Now 1 ton is 3504 Watts of cooling capacity. So TAFU can range between 0.34 ton to 1.5 ton. CAFU can range between 0.23 ton to 1.85 ton. The nominal capacity of CAFU is lower and that is why its power consumption is lower.

Now CAFU has a better cooling capacity range, but if you look at its lowest capacity and power consumption then for 800 Watts of cooling it consumes 330 Watts. But TAFU gives 1204 Watts of cooling by using 303 Watts. And that is why TAFU is more energy efficient and it shows up on its ISEER numbers. CAFU has better cooling capacity so it will cool faster. But TAFU will be more energy efficient.

5cnhw18pafu is a BEE 5 star rated model, so it certainly the best from Blue Star. I have personally not heard complaints about their noise. So I cannot comment on that.

Hi Abhishek, I am Kowshik from Hyderabad. I would like to buy 1 Ton AC for my 10*10 room which is in first floor. Could you please suggest me which AC's will offer the best after sales support in Hyderabad so that I can decide the brand to buy accordingly. Thanks in advance.

8
Abhishek Jain (Mod)

Hi Kowshik,

We do not have local information on which brands will be good in Hyderabad. So I am sorry, it would be difficult for me to provide the information. Also I cannot suggest anything without knowing the budget that you have. In general Best 1 ton ACs are:

1) Daikin JTKM35
2) Hitachi Kashikoi 5400i
3) Blue Star 5CNHW12PAFU (Amazon Link: http://amzn.to/2rf5VaG )

9

Hello sir ,
I visited showroom for price survey of Hitachi kashikoi 5400i series but those price are very high. Please suggest some others trusted brands with series and also about Blue star energy efficient series or model number. Is 1ton inverter 5star AC sufficient for 10/12' length & hight 10ft ground floor south facing room. What type of customer service of Blue star AC in south kolkata.

10
Abhishek Jain (Mod)

1 ton inverter AC should be fine for your room. You can look at Blue Star 5CNHW12PAFU (Amazon Link: http://amzn.to/2onV5KU )..... It will be difficult for me to tell about their service in south kolkata. You will have to get this information from local people and dealers in your locality.

11

as per the calculations above the requirement is 3.7 ton,, what would you suggest

12
Abhishek Jain (Mod)

You will have to go for two numbers of 2 ton AC for the room to cool the whole room. If you want local cooling (close to the area of seating) then you can go for a single 2 ton AC as well. But that will not cool the whole room.

13

Hi I am from Kolkata. i wanna know one thing. I have used bijlibachao's ac tonnage calculator for calculation. According to my room size it has given 1.5 ton when i checked two point of direct sunlight and west wall sunlight while without checking of direct sunlight point it has given 1 ton. So, my question is here that if i would use ac only for night hours (11PM to 7AM), then 1 ton is sufficient for that? Or 1.5 ton must be required as room gets direct sunlight, even if i would use ac only for night hours.

14
Abhishek Jain (Mod)

Hi Surojit,

The calculator also gives exact tonnage requirement. It says something link: "1.5 Ton (For cooling requirement of 1.3 Ton)" ... which means your room's cooling requirement is 1.3 ton, but as typical marketing tonnages are 1,1.5,2, etc, that is why it says 1.5 ton. So just check the actual requirement as well.

Now the cooling requirement is less during night for sure. And most likely 1 ton should be sufficient for your use. However, please note that because the ceiling is directly facing the heat outside, the room will be hotter as compared to having a room on top of this room. But still I think 1 ton should be fine if your usage is only at night.

15

Hi, Abhisekh
We have communication here today. But not getting in the page Now. Expecting your valuable response of my last query on model suggestion.

16
Abhishek Jain (Mod)

Copying it again, also this message goes to your email as well. You can track old communication on emails. Here was my reply:

Hi Sanket,

I am not recommending to buy online. You can very well purchase offline. I give online links because 1) There are lot of user reviews on the online platforms that can help someone decide. 2) Just to make it easy to find them on online stores to get idea on price as well.

If you want good air filters then you should go for Blue Star or Panasonic or LG. You can look at these models:

Sir, I want to buy an AC for my 10/12 size bed room hight 10 ft home, I planned for go with Hitachi but when I visit in showroom, salesman show their wattage chart and describe that "Carrier" is best now and Carrier brings in market inverter 4 stars 1.5ton technology but Hitachi not. Please tell me is Carrier company is best than Hitachi. Please Suggest me the which one best.

18
Abhishek Jain (Mod)

Hello Mr Surajit,

There are many models from Hitachi that would be better in terms of electricity consumption than Carrier 4 star 1.5 ton inverter AC. Hitachi has Kashikoi 5400 series, 5300 series , 5200 series which will be far better than Carrier 4 star inverter AC. If electricity consumption is your parameter then Carrier does not rank high for sure. Hitachi, Daikin, Blue Star, Godrej have some of the most energy efficient ACs.

In terms of durability, I would not say Carrier would be better than Hitachi. I would say they are quite similar.

For features, you will have to compare models because some models have better features than other.

And finally as far as service is concerned, you will have to gather local feedback. Because some brands are good at some places some are not. We have heard some bad stories about Hitachi from some places. But not so much for Carrier. But for that local feedback (in your city) is always better.

Abhishek Jain (Mod)

Hi Debashis,

You need a 1.5 ton inverter AC for your room. What is the budget that you have for this AC? If you just want the most efficient then these are two models from Hitachi and Blue Star that are the most efficient:

Hitachi Kashikoi 5400i
Blue Star 5CNHW18PAFU (Amazon Link: http://amzn.to/2qsd2e7 )

23

I use ac for 4 to 5 hours a day.
I need a 1.5ton ac
Want to get the best performing machine which yields me lesser power bills and also a machine that lasts long without rising any issues all the time.
I heard that inverter machines rises issues....I don't know if it is right or not.
So, I'm little bit confused between 5star rated ac and inverter class machines.
Please suggest me between them. As the price difference between those models are almost 10000rs.
I want to know whether Spending 10000 is rational for getting inverter or else I have to go with 5star...?
By the way I'm writing this question keeping Mitsubishi Electric in my mind.
If any other brand is better please tell me as I'm spending almost 60k almost.

24
Abhishek Jain (Mod)

Hi Nandan,

For 4-5 hrs of usage you will not be able to recover 10K. Mitsubishi Electric is a great brand. You may also look at Mitsubishi Heavy Industries or O General.

25

Dear Abhishek,
I need 04 A/cs, Split Type. 03 A/C of 1.5 TR. For 1.5 TR i have narrowed to "Hitachi RSA518CAEA" or "O-General - ASGA18FETA" or "OGENERAL ASGA18FUTA". Which is better and why. One thing i would like to mention that in my area there is frequent power failure and then change over to generator (sometimes 3-4 times a day). Will it effect life/damage to of invertor AC?
Please advise which one i should select.

secondly i have a drawing room with 10 feet width and 20 feet length which is open towards dining area(8 feet by 8 feet). Will 2.5 tons A/C be good enough? Should it be invertor type or fixed type. Please advise? Thanks in advance

Abhishek Jain (Mod)

Hi Ranjan,

Right tonnage depends on city, room's location (if it gets direct sunlight on walls/ceiling or not), size of the room and number of people in the room, etc. Usually we assume 4 people in a room to do some calculations. But other parameters are required to be known to calculate the right size. A city like mumbai needs less cooling because temperatures do not go too high. But a city like Delhi needs more cooling because it is too hot in summers. Similarly a room on top floor getting direct sunlight on the roof will need more cooling as compared to a room on lower floors. So I would suggest that you use the calculator on this page to calculate the right tonnage. Also if the room is open then you will have to take total area of both the rooms (so 10x20 + 8x8 = 264 sq ft).

Also choice of inverter and fixed depends on annual usage of the AC. If the usage is high inverter would be beneficial, else fixed would be good. Again the calculator on this page can help you calculate the expected electricity costs based on your usage.

Power surges can damage PCBs in inverter AC. Surge happens when the voltage increases sharply and suddenly. You can use a surge protector or a voltage stabilizer with surge protection feature to save your inverter AC.

Among the models you have listed, Hitachi RSA518CAEA has really high energy efficiency (or electricity saving). Brand wise both General and Hitachi are premium. Hitachi model has lot of advanced sensors for performance optimization as well. So that is the best AC among the 3.

27
R.Bhattacharyya

Best and economical ac to buy

28

Hi,
I am a bit confused after reading the aforesaid article and the query resolutions comments below. In the article the best AC for India are proposed to be Hitachi, Daikin, O General, Mitsubishi & Blue star (brands like Carrier, Panasonic etc. are not mentioned at all in the league, however in the below comments, it's being said that Panasonic & Carrier are one the best premium ACs with one of the best performance in line with Hitachi. If that would be the case then why were they not mentioned in the article????. Also would like to know keeping the price factor aside aren't the Korean ACs LG & Samsung not up to the standard to their Japanese competitors??? Would appreciate a clearer picture on comparatives enabling us to make an informed judgment in selecting the best AC

29
Abhishek Jain (Mod)

I guess you are looking for a black or white answer, but the world is grey. Saying something is best or premium is more of a perception of an individual. And perception is more subjective than objective. Now it is not that all the brands are same of if I say Hitachi, Daikin, General, etc as premium then no one else can add anything. The thing is based on my perception Hitachi, Daikin, General, Mitsubishi, Blue Star are the best. If I have to choose between a similar model of Mitsubishi and Carrier, then I would choose Mitsubishi. But Carrier is better than LG or Samsung for sure. But then one has to look at models and not brands.

If you are buying a car, you cannot compare a Hyundai i10 with Honda City. They are two different models and different segments. But if I have to compare Hyundai Verna and Honda City, then I would prefer Honda City. But then if I have to choose between Hyundai Verna and Honda Brio, then I would prefer Hyundai Verna. You cannot compare brands to make a judgement, you have to compare models that come in your budget, looking at their specifications.

And technology wise I would say Japanese are better than Koreans. But koreans are not too bad. Hyundai is a Korean car company, makes great cars. But then people prefer Honda a Japanese brand.

Bottomline, it is all perception. Carrier is not bad at all and I perceive it as a better brand than LG. But not better than Mitsubishi. But then I cannot box them into premium and non premium just like that easily. However, if someone gets confused if Carrier is good or not, it definitely is very good. Same for Panasonic. It is a fantastic brand. If in my budget I get a better model from Panasonic as compared to a Hitachi, I will surely go for Panasonic.

Hello sir,
I want to Purchase a 1 ton inverter Ac for my room size 8*10*10. Can u suggest me ( LG jsq 12apxd, LG jsq 12 ptxd , Voltas 123v my and bluestar 3cnhw12tafu which one is best in term of cooling & others functions.

33
Abhishek Jain (Mod)

Hi Nitin,

I think Blue Star 3CNHW12TAFU would be the best among all you have mentioned.

34

Abhishek ji,
I am from Delhi, further Details are as submitted below :
Enter Length of Room (in ft):25
Enter Breadth of Room (in ft):16
Enter Height of Room (in ft):9

Check this if the ceiling of the room gets direct sunlight from top during the day - YES

Check this if West, South or South West walls of the room get direct sunlight during the day - YES

There is a Glass window of 5' × 5' & a Door of 7' × 5' on southwest Wall Dimensions are 25' × 9'.

Enter Daily Usage in Hours: 6-8 Hrs (DayTime)
Enter Number of Months in a Year you will use the AC: 7-8
Outputs: Size of Air Conditioner that you need: 4.2 Ton (For cooling requirement of 4.2 Ton)
The above is Copied & Pasted (This Site only)
I further would like to add, this Entire Structure (Walls & RoofTop) is a PortaCabin made up of 3" Thermocol Insulation Sandwiched Inbetween 2 GI Sheets of 0.5 mm Thickness with High SRI 122 Paint (Cool Roof Coating) on Exterior from (Indian Insulation& Engineering) 1 of the 5-6 options suggested by this very site with Galse Ceiling as well.
Also, based on inputs I donot wish to go in for Inverter ACs instead would go for 4 / 5 * ACs as per your suggestion.
My Questions are :
1. Split or Window (have Space for any of the 2) ?
2. How many Units and There Division in terms of Tonnage ?
3. Also, does the direction of Unit Installed has an effect on its performance ?
Kindly suggest Models from O'General, Mitsubishi or Daikin.

Thanking you in advance for the time and effort you put in.

35
Abhishek Jain (Mod)

If you have solid insulation put up, I think you can go for 3-3.5 tons of cooling as well. I would not suggest inverter AC just because the space is too big and it is quite likely that heat load may go up. Here is my answer to your questions:

1) You will get better options in split AC. However, if you are looking for 4* AC then you can get similar options (options with similar energy efficiency) in window AC as well.

2) You may go for two 1.5 ton AC or two 1.7-1.8 ton AC. I think 1.5 ton ACs would be better.

3) Units should be installed in such a way that the outdoor units do not face direct sun throughout the day. It will be better that way.

If you are thinking of Mitsubishi, then two of Mitsubishi Heavy SRK 20 CSS-S6 (link: http://www.iaplgroup.com/srk20css-s6_srk25css-s6.php ) would be more than enough for your room and it will cool really well. Otherwise you can also look at these:

Hello Sir,
Previously as per my requirement & query; you have suggested me Daikin FTHP50SRV16 . But after ordering the same unit; it seems that DAIKIN is unable to complete the order at present. Saying that there is not much electricity consumption wise difference between inverter & non inverter model.
At this moment kindly guide me to select an 1.50 Ton Hot & Cold Split Invereter AC as an alternative.
Thanxs.

37
Abhishek Jain (Mod)

Hi,

You can also look at Blue Star 5HNHW18PAFU. It is also a good hot and cold AC. Electricity consumption wise there is a lot of difference between inverter and non inverter models. Which non inverter model are they saying consumes same as inverter model?

38

Hello Sir,
They are saying @ DAIKIN's FTYN50JXV16 ( Non Inverter model with Refrigerant R-410) instead of FTHP50SRV16 (as per my order with Refrigerant R-32)) & recently it's learned from DAIKIN's corporate office that they have not produced the model. so they are unable to fulfill my order till Jun17.

By the way FTYK50 has EER/ISEER of 3.21/3.54 (cooling/heating) whereas that of FTHP is 4.17/4.17. There is a huge difference in electricity consumption of the two. You can check their specs on these links:

FTHP: http://www.daikinindia.com/products-services/split/wall-mounted-type-r-32-fthp-series-cooling-heating-1
FTYN: http://www.daikinindia.com/products-services/split/wall-mounted-type-r-410a-ftyn-series-heat-pump-0

FTYN if rated on BEE star rating would be equivalent to BEE 3 star non inverter AC whereas FTHP is equivalent to BEE 4 star rated inverter AC. And BEE 5 star rated non inverter AC would be equivalent or less as compared to BEE 3 star rated inverter AC. So there is a huge difference.

For hot and cold any of these models would be good: 5HNHW18PAFU (5 star) or Daikin FTHP50SRV16 (4 star) or Blue Star HNHW18CBFU (3 star) or Carrier Superia 365 inverter 1.5 ton

Hello sir,
I'm looking for the comparison which was previously available showing Company Name, Model, Star Ratings, Annual electricity consumption. In which we can sort according to Company Name, Model No. & all factors for comparison.

We changed it because the software that we were using to display it was slowing down the website significantly. We do not have it now.

Hi Abhishek,

I was planning to buy an AC but confused between inverter & normal ACs. I had almost finalized inverter AC when I came to know that Inverter AC has the problem with PCB circuits. If there is a breakdown of PCB, it is nonrepairable in most of the inverter models of all brands and it can cost 12-15k for replacement of same. is it true? what are the chances of the breakdown of PCB.

Please share your view on this

43
Abhishek Jain (Mod)

Hi Sanket,

PCB usually get damaged due to two reasons: 1) Power Surges 2) Corrosion. As for power surges, there is protection available. You can either use a surge protector or voltage stabilizer with thermal overload protection. Or to go for an AC that can handle big voltage range (Samsung and LG have models that can work between 90V and 450V). But then preventing any metal from corrosion is difficult. I have not seen any brand that provides corrosion protection for PCB. One can spray protective coating for the PCB, but then again it will not last long if the corrosion levels are high. So usually we do not recommend people to go for inverter AC is the corrosion levels are high.

Corrosion levels are high if you live close to a water body (Sea, River, Lake, Nalla) or close to a chemical factory. If the environment is not corrosive, you can go for inverter AC.

44

Thanks, Abhishek. I am from Ahmedabad and there is no problem of corrosion at all. I will check if the power surge is there or not. We are getting electricity from Torrent power so I don't think that would be an issue either.

So now what will be the better choice in inverter AC from below mentioned blue star models. Please suggest other models in 40K budget.
Blue Star - 3CNHW18CAF, 3CNHW18TAFU, 3CNHW18NAFU

45
Abhishek Jain (Mod)

Hi Sanket,

Torrent Power should provide quite stable and good power quality. So I do not think there should be any problem with inverter AC. In a budget of 40K, I think LG has really efficient models. I would suggest that you look at these:

LG JS-Q18SUXD (Amazon Link: http://amzn.to/2oMG2Le )

LG JS-Q18AUXA (Amazon Link: http://amzn.to/2oMjWqB )

Voltas 183V EY (Flipkart Link: http://fkrt.it/4zTJATuuuN )

Blue Star 3CNHW18NAFU

Daikin FTKH50 (Flipkart Link: http://fkrt.it/PsYIxTuuuN )

Any of these would be good. 3CNHW18TAFU is also very good, but I think it would go slightly beyond 40K.

46

Hello sir,
I want to run a 1.0 ton inverter Ac on my existing 2 Kva luminous cruze model with double battery it is possible or not if not possible then suggests me how much inverter should be required to run this load

47
Abhishek Jain (Mod)

Hi Nitin,

2kVA inverter can easily run a 1 ton inverter AC.

48
Siddharth Mehta

Hey Abhishek,
I need your opinion, I need to buy smart ac, inverter type for my drawing room, 25th floor, north facing, no direct sunlight, but AMPLE NATURAL LIGHT, it has rectangular shape of 26 sq feet, but has additional 65 sqft, in Lobby/passageway. It has two large bay windows of glass area of 49x2 = 98sqft. Although utilization is less than 4 hours a day for 7 months, but i would still like to go green, thats why inclined to buy Inverter type. I have had Hitachi Inverter 1.5 & 1.2T in bedrooms, but remote controllers are shabby, ACs work OK, not super brilliant, but yes quite efficient. I am getting different results on different website for TOnnage calculations. I am inclined towards buying Diakin FTKP Series - 2.2T. Thanks!

49
Abhishek Jain (Mod)

Hi Siddharth,

Did you try using the calculator on this site? What did it suggest you? You will have to sum up the total area (including the lobby) to calculate the right size. Let me know the tonnage that the calculator suggests and also your budget and I can suggest you some models.

50
Siddharth Mehta

Thanks for the early reply Abhishek. Calc says 3Tonn, to be very honest it looks unreal. I can spend up to 60k if the need be. My personal choice is always to invest in a Robust product, which Performs with least maintenance and is green in terms of energy (added options like wifi connectivity to remotely operate will be added pleasure). I wont be changing my acs for years, hence i want to invest one time. I have Hitachi Kashkoi500i Auto Clean Inverter Acs in all three bedrooms, energy expenses should be least.
I was inclined towards buying Diakin this time, and i was assuming 2.2Ton, 4 Star, Inverter Ac should be good. I was hoping to share pics with you, so that you could have idea of room/bay windows (glass.. 49sqft, with ample light).

51
Abhishek Jain (Mod)

Hi Siddharth,

The area is really big and thus the calculator is suggesting 3 Ton. Also your city's temperature may be high during peak summers. In general the tonnage is calculated by evaluating the heat load based on room's size, city and room's location (direct sunlight on walls/roof add to heat load). Also a city like Delhi has higher heat load as compared to a city like Mumbai. So a 2 ton AC may be fine for a 300 sq ft space in Mumbai but may fall short for a similar space in Delhi. So it depends.

I would suggest that you look at Mitsubishi Heavy Industries ACs, the hybrid non inverter ACs. Usually if the space is big, undersizing inverter AC does not help because inverter ACs are least efficient at peak capacity. So a 2.2 ton AC if it runs at 2.4 ton, then its efficiency is lowest at 2.4 ton. And thus desired power consumption is not achieved. I would suggest that you look at Mitsubishi Heavy Industries SRK 25 CSS-S6 (check this link: http://www.iaplgroup.com/srk20css-s6_srk25css-s6.php ). MHI models have long air flow models, that help cover larger area. The energy efficiency is also really good for their ACs.

52

Hii Abhishek,
As prescribed in your blog..My requirement for AC is 1.5 ton in Faridabad(Delhi),
Please suggest AC, whether I should go for inverter or non inverter AC, my usage will be 8 hrs in night and 2 hrs in day...
I have picked Daikin DTF 1.5 ton non inverter, Daikin HTKN50 INVERTER AC 5 STAR, and Daikin FTKH 3 star inverter AC from premium brands, and from middle and lower range Carrier 1.5 ton 4 Star inverter AC 18k Superia, Sansui 3Star inverter AC.
Also my requirement includes Corrosive protection...
Please guide from above or any other model fulfilling my requirement.
Also please explain ROI on the models.

Hoping your earliest reply as I am eager to buy AC

53
Abhishek Jain (Mod)

Hi Vipin,

ROI depends on annual usage. Your usage is 10 hrs a day which means 300 hrs a month. But then it will not be 300 hrs every month. It will be less in some month and more in other. Usually between 1600 hrs of usage to 2000 hrs of usage (in Delhi tariff), a BEE 3 star rated inverter AC should be good enough. Also Carrier is a premium brand and is not a lower range brand. Sansui would be lower range. For strong corrosion protection you should look at brands like Blue Star, Panasonic, Hitachi. Daikin also has a few models with corrosion protection. How many months do you use AC? Also what is your budget for this AC?

54

Sir, my budget is upto 43k, and AC usage will be upto 7 months (Apr-Oct), please suggest AC's also considering corrosion protection...

55

Hello Abhishek..
Is Hyundai 1.5 ton Inverter AC will be good choice ..As it is cheap (30k), and having copper wire, corrosion protection..A 3 star inverter AC....Or 5 star fixed normal AC with copper wire and condenser available in 38k..For Daikin, Hitachi, Voltas, blue star, all premium brands..

56
Abhishek Jain (Mod)

Hi Vipin,

It is not that the Hyundai AC will not work. It will work well if you choose the right AC for your room's requirements and if it is installed properly. And in fact being inverter AC it will also run efficiently. However, the best thing that a premium brand bring is the long term performance. Every AC derates (performance decreases with time). The rate of deration is low in premium brands. In short term I think this Hyundai Inverter AC will be good. I am not sure of its long term performance.

57
Abhishek Jain (Mod)

Hi Vipin,

BEE 3 or 4 star rated inverter AC would be the best for you. I guess you checked Carrier Superia 4i on Flipkart (link: http://fkrt.it/CE1JG!NNNN , Amazon Link: http://amzn.to/2qr40hF ) .... if this is the one that you are looking at then I think this is an awesome deal. It is difficult to get BEE 4 star rated inverter AC in 43K budget. So if you are planning for this then I think you should go ahead.

Else in BEE 3 star you can look at these:

Hitachi RSH318EAEA (Amazon Link: http://amzn.to/2oDyR7E )
Blue Star 3CNHW18TAFU
LG JS-Q18AUXA (Amazon Link: http://amzn.to/2rpKteZ )

Blue Star and Hitachi would have best corrosion protection.

58

Thanks for prompt reply. can you please suggest me 1.5 ton split Invertor AC as well as 2 ton split Invertor AC, of which brand should I buy considering lowest consumption of electricity (i.e. energy efficient brand & model).

59
Abhishek Jain (Mod)

These are the most energy efficient (lowest power consuming) models in 1.5 ton:

Daikin JTKM50
Hitachi RSA518CAEA
Godrej GSC 18 GIG 5 DGOG (Amazon Link: http://amzn.to/2nppn1y , Flipkart Link: http://fkrt.it/qbdnm!NNNN )
Hitachi RSB518IAEA
Blue Star 5CNHW18PAFU (Amazon Link: http://amzn.to/2nTRbZD )

These are 2 ton ACs:

Mitsubishi Electric MSY-GK24VA
Hitachi RMC424EAEA

60

what is the difference between Mitsubishi MSY-GK24VA and Mitsubishi MS-GK24VA split air conditioner

61
Abhishek Jain (Mod)

MSY is inverter technology air conditioner series whereas MS is non inverter series. So there is a big difference in technology.

62

PLEASE your opinion about this model "Carrier 1.5 Ton Inverter 4 Star 18K Superia Inverter Split AC 4i CO CACI18SU4I1 Split AC White" for home usage.

63
Abhishek Jain (Mod)

Hi Raj,

Superia is a very good series from Carrier and Carrier is a great brand. So You can certainly go for this AC.

64

Thanks abhi. If you suggest suitable stabilizer for this model that will be more helpful.

65
Abhishek Jain (Mod)

Choice of stabilizer depends on how low your voltage drops. If the fluctuation is not much then you can go for basic stabilizer. If it is more or lot, then you can go for a double booster or triple booster stabilizer. How low does voltage usually drops in your area?

66

HI ABHISHEK,
MY ROOM IS 10*10*12. (L*b*H*) MY BUDGET IS AROUND 45 K. I WANT TO BUY 5STAR 1 TON INVERTER AC. KINDLY SUGGEST ME BEST OPTION FROM HITACHI OR BLUESTAR OR ANYOTHER MODEL U REFER????

67
Abhishek Jain (Mod)

Hello Mr Soni,

I think BLUESTAR 5CNHW12PAFU (Amazon Link: http://amzn.to/2onV5KU ) would be the best option for you. It will easily fit in your budget and it is among top 3/4 most efficient models. I think Hitachi models will go beyond your budget.

68

Plz suggest me two ton AC of which brand I have to buy and consumption of electricity is much lesser

69
Abhishek Jain (Mod)

Inverter Tech ACs would be the most efficient. You can check these Inverter Tech ACs:

Mitsubishi Electric MSY-GK24VA
Hitachi RMC424EAEA
Hitachi RMB324IAEA
Blue Star 3CNHW24TAFU

(In decreasing order of energy efficiency or increasing order of electricity consumption).

70

Hi,Tks for your prompt reply of my mail of 3rd may,The sizing given to you was done based on the info given in your write up.
I have also sized as per chart given by the flg mfg and result is as flg,
Hitachi-1.8 t
samsung-1.5t
BB(you)-1.5t
blue star-2.0 t
LG-1.5 t
Godrej-2.2 t
Since i do want buy a 1.5 t ac as suggested by you,pl check this once again.
The room in consideration gets sun light only upto 3.00 pm and that to up to 1/4 of the room only.
Or, should to be on safe side go far 1.8 ton hitachi model rau522awd.
pl advise at the earliest.

71
Abhishek Jain (Mod)

In Mumbai the temperature does not go really high. Believe me, I have a 0.75 ton AC for my 130 sq ft room in Mumbai and it works great. Although for me 1 ton was ideal size, I went for a bit small AC. And it still works great (because my usage is mostly at night), and even during the day it does make the room comfortable. And the electricity consumption is low. So I think 1.5 ton should work fine for your room. And your usage is only at night so 1.5 ton will be perfect.

72

hi,
tks, for your reply of 14th instant,cani go for blue star model 5HW18AATU,1.5 ton,5 star model,
Gooday,
Ram.

73
Abhishek Jain (Mod)

Blue Star is a good brand and this is a good model. You can certainly go for it.

LG models with AU, SU and TU in the name are copper.

76

Hi,
i want to buy an AC for my room size 12*15*12. The room is covered with other rooms and thus no source of sun light. the room has 1 ventilator which opens in a Shaft. Please suggest if 1 Ton Window AC will do the job.

77
Abhishek Jain (Mod)

Which city are you in?

78

I reside in delhi

79
Abhishek Jain (Mod)

Hi Kunal,

1 ton would be really small for your room. As per my calculations, you need about 2 tons of cooling. 1.5 ton will barely make the room comfortable. 1 ton would be super small.

80

Hi Abhishek,
Daikin jtkm35 and jtkm50 both are best in their segment. But these models do not have any anti corrosion cover. Will it be an issue. I live in Kolkata not near any river. And my second question is 2) How good are godrej acs? as their warranty coverage is longer will it a be a good choice?

81
Abhishek Jain (Mod)

If you are not in corrosive environment then anti corrosion cover will not be a big issue.

Godrej also has highly energy efficient ACs and on top of it they use R290 which is greenest refrigerant in the market. However, copper condenser to support R290 is not available in Indian market yet, so they use Aluminium condenser. And all brands using Aluminium are giving longer warranties. That is because aluminium has got a lot of bad press lately. They are especially troublesome in corrosive environment. But just because they are troublesome in corrosive environment, everyone asks for copper condenser. And that is why to give confidence to consumers, they give longer warranty. It will not fail in non corrosive environment.

82

Hi Tanmoy !! I think you will not get those JTKM series. Because they are all sold out and even currently out of stock in their company also. So do research more for another models. I bought CTKP50 last week which is the latest model of this year. And I'm also from kolkata (Narendrapur area).

83

Hi Abhishek,
Can you help me for select in two ac.
Mitashi 1.5 ton split inverter ac
Sansuai 1.5 ton split inverter ac.

Thanks
Gaurav

84
Abhishek Jain (Mod)

Hi Gaurav,

Sansui model (Flipkart Link: http://fkrt.it/3v4wC!NNNN ) has ISEER of 3.77 and Mitashi Model (Flipkart Link: http://fkrt.it/pD1hkTuuuN ) has ISEER of 3.6. Rest of the specs are very similar. So I would say Sansui model is better than Mitashi model.

85

Dear Abhishek,
I am looking for 1 Ton 3 Star Non Inverter AC in Pune.
My requirements are:
1. 100% copper coils
2. Better Cooling effect
3. Auto on/off feature
4. Good Life - about 10 years without much maintenance
5. Medium Price range - I am looking for brands that are somewhere in between lower (e.g. Videocon, Voltas, etc.) and premium brands ( e.g. Carrier, Bluestar, etc.) . So I am looking something in between Hitachi and Panasonic.

Let me know please if my shortlisted brands Hitachi & Panasonic are good fit for my requirements and price category?
Secondly, which one should I go for among Hitachi (Ridaa/Neo 3200F) and Panasonic (YC12SKY3S/or KC12SKY3) ?

86
Abhishek Jain (Mod)

Hello Mr Kundan,

Hitachi and Panasonic are not medium price brands. They are in fact premium priced brands (just like Daikin, General, Mitsubishi, etc). BlueStar, LG, Samsung, Voltas are the ones that are medium price range. Videocon, Onida, Lloyd, etc are the lower price range brands. Hitachi models that are more feature rich are extremely pricey. I think the same goes for Panasonic. Their basic models (with less features) are cheaper. But Hitachi and Pansonic have great ACs, so if you want to go for them, then they are great choice. And among Hitachi and Panasonic, I would say Hitachi has slightly more energy efficient ACs. So Hitachi Ridaa would be a good choice. Both Hitachi and Panasonic have 100% copper with corrosion protection. So they are a great choice.

87

Hello sir i have 2 questions plz clarify them for me
1) which is the best solar hybrid air conditioner name one i can import it from outside.
2) is it possible to convert my existing split ac at home to run on solar power by making external arrangement s like syncing it to solar setup?

88
Abhishek Jain (Mod)

There are two types of solar energy systems in the market: 1) Solar Photo Voltaic 2) Solar Thermal. Solar Photovoltaic generates electricity using sun's light. Whereas Solar Thermal uses "heat" from the sun rays to heat something. Please note, there are two different types of energies being used in the two: one is light and other is heat.

Now Solar PV systems which are used to generate electricity are max 18-20% efficient till now. Which means they are able to convert only 18-20% of light energy that they receive. They are expensive for running smaller systems (the costs that you hear in newspapers are for large mega scale systems).

Solar Thermal is 80-85% efficient in capturing heat from the sun and is quite cheap as compared to PV. This is used in Solar Water heaters, Solar Cookers, etc.

There are two types of solar hybrid ACs available in market:

1) A simple one that works on Solar PV. Which will be really costly as the costs of PV systems are high and then again its efficiency would be quite low. So cost of running will come out very expensive.

2) The more cost effective one works on Solar Thermal. Within an AC the compressor compresses the refrigerant to make it hot liquid. Solar Thermal is used before compressor to pre heat the gas, so that compressor does not have to work much and thus its electricity consumption is reduced.

There are manufacturers in India who can give you both types of ACs. Videocon sells a solution which is based on Solar PV. Search for Videocon Solar Hybrid AC and you will get to the link. But I would say that it is not a good solution at all.

There are some manufacturers (small ones though) that sell Solar Thermal ACs. Search for Onyx Hybrid AC on google and you will get to one such company. I think this is a better solution, but then again these guys use regular non efficient compressor. So the overall efficiency does not turn out to be too high and thus it does not beat an inverter compressor ACs available in market (in terms of economics).

An ideal solution would be one with Solar Thermal and Inverter Compressor. But I have not seen any such solution in the market (indian or imported). So the best solution is to go for inverter compressor AC (for electricity saving).

As for using existing split AC: if it is one with inverter compressor, then you can easily connected it to any grid connected (system without batteries where you sell power to the grid) or off-grid system (one with batteries). But if it is a non inverter system, then the best system to run it is a grid connected system where you do not have batteries, and you send the generated power to the grid and you get billed for the net power that is used (Consumed-sent).

89

Hi Abhishek,

How is videocon VSM 55.WV 1.5 ton 5 star split ac for a room of 150 square feet in mumbai. This ac will be used mostly during night.

Thanks
Parvez

90
Abhishek Jain (Mod)

Hello Parvez,

1.5 Ton will be quite big for a 150 sq ft room, especially if you plan to use it only at night. I think a 1 ton AC would be good enough for your needs.

91

Hi Abhishekh,

Thanks for your reply. I already bought this AC. I want to know is this model videocon VSM 55.WV a good one as many people told me videocon ACs are not good, it as reliability issues.

Thanks & Regards
Parvez

92
Abhishek Jain (Mod)

Hi Parvez,

Videocon models are quite cheap. Most of them are imported from China. Not that Chinese products are bad, but what I mean to say is that they are not engineered in India. It does have less durability as compared to premium brands.

93

Hi Abhishek, Can you help me decide tonnage and model for AC for Kids room 10X8sqft , with bunker bed to the wall . Which model do you suggest, as A/C can be fixed a 3 ft away from bed and cannot give direct wind to the bed.I may have to use a table fan also to direct some cool wind to the bed. And for another room of 25X 10 soft room do we need to use 2 a/c s? I am contemplating between 5 star Godrej and Blue star. Would u suggest inverter ac? We use ac for 3-4 months max and day time for 2 months. Current supply cut is a lot here in outer of Hyderabad where we live. Wish AC work with solar.

94
Abhishek Jain (Mod)

Hi Janaki,

In most places in the country a 0.75 ton AC should be good enough for a 80 sq ft room. If you are looking at Blue Star then I would suggest Blue Star 3CNHW09CAFU model for the room. It will be good. Also the AC will cool the whole room and you would not need any fan to redirect cold air (unless the kids really want cold air on their face). I think they will feel comfortable without cold air on their face. If you are looking for non inverter then Blue Star 5HW09SAFU would be good.

Choice of inverter/non inverter depends on annual hours of usage and electricity tariff. How many hours do you use the AC for? I think 5 star would be good. For your 250 sq ft room in Hyd, you may go for 2 ton AC.

95

Thank you Abhishek for your immediate reply? We use ac for 3hrs in daytime and 8 hrs in night. Which ac is efficient and long lasting in the market. Which ac can work well with solar power. I chose bluestar only because of BEE ranking. I will need .75, 1.5 two no.s and 2T. Is it advisable to buy from same brands or different brands. I have a I living room with double height corner, open to stairs and open kitchen. We have no clue how to cool this room. Even if we close the kitchen, the double height and open to staircase for 2 more floors cannot be closed.

96
Abhishek Jain (Mod)

If you are thinking of off-grid solar (one with batteries), then it will be better to go for inverter tech AC. Else if you plan to go for a grid connected solar (where electricity you generate is sent back to the grid and you are billed only for the net you use), then you can go for inverter or non inverter. In both cases inverter tech would be good.

With single brand AC, managing service would be easier for you (one technician will do it all). But then I would not say that either way is good or bad. If you have flexibility with brands, you can get the best for each room based on usage, efficiency level and price. If you go for single brand, then you will have to go for the best that you can get in that brand, may not be the best solution for the room's requirements. But Blue Star this year has come out with highly efficient ACs and they have good models in each star rating range. So single brand Blue Star may not be a bad choice at all. Also in case you have an open space like the one you have explained, in that case I would not suggest inverter AC just because inverter ACs are not very efficient at peak capacity (which is more than rated capacity). And if the space is open, the AC will always run at peak capacity. IN that case going for normal BEE 5 star rated non inverter AC would be good enough.

97

Hi Abhishek,
I am looking for buying a 1.5T spit ac for drawing room. There is on direct sunlight. It will be used for approx 3-4 hrs a day for approx a month & in case of there are guests(once in 2 months approx) then it will run for 5-6 hrs. Please suggest accordingly.

98

Hi Abhishek,
Thanks for sharing the models. But a friend of mine suggested to go for inverter split ac instead for savings. Is it true that it consumes less power as compared to 3 star non inverter ac(which you have suggested above). I live in faridabad(delhi-NCR). If yes then please suggest the same.

100
Abhishek Jain (Mod)

Hi Amit,

You mentioned that your usage is only for 3-4 hours a day for a month. In that case you will not achieve ROI on an inverter AC. I can certainly suggest you inverter AC if you want to, as it will certainly save some electricity. What is your budget for this AC?

101

yes, But over the time usage increases. What if usage increases to 5-6 hrs for 2/3 months. which will be the best option inverter or non inverter. Budget is 40K. Will inverter ac work in faridabad properly

102
Abhishek Jain (Mod)

Hi Amit,

All these BEE 3 star rated inverter ACs will fit in your budget, you can go for any one of them:

If your environment is not very corrosive (close to sea, water body or any chemical factory), then inverter AC should work well.

103

Hi Abhishek,

All your articles are interesting. Thanks for sharing.

I am from Chennai and have an old 1.5 ton carrier window ac (2 star, GWRAC018DR001 of 2009) in my room (200.5 sq.ft = 12.3x16.3, 10 ft height, no top floor, direct sun light, 13.5 sq.ft glass window). Its power consumption mentioned on the label is 1889 watts with no variable speed compressor. Since the power consumption bill is going very high, I am just trying to understand the approximate bill, considering the compressor is on for 75% of the time and 8 hours a day and for 60 days electricity billing cycle. It comes around 680 units (1.889 x 0.75 x 8 x 60). The unit cost is Rs.6.60, and hence the bill comes around for Rs.4500. I am thinking of replacing this one with Hitachi Kashikoi 5400i/5300i (1.5 ton, 5 star inverter split ac) for reducing the bill. Power input of 5400i and 5300i are mentioned in the spec as 454w to 1374w and 495w to 1415w respectively. Please suggest whether this will be the right choice and what would be approximate bill amount if I buy this one.

Also, I am planning to buy another AC for another room (143 sq.ft = 13.55x10.5, 10 ft height, no top floor, direct sun light, two 13.5 sq.ft glass windows) and planning to buy 5 star 1.5 ton ac. Will this be right-sized? Can I go for below 1.5 ton for this room? Also I am thinking of not buying the two ACs from the same brand. What is the alternative I can think of? Please suggest.

Thanks.

For inverter AC you cannot apply 75% cycle time because there are no on/off cycles in inverter AC. If you look at the BEE label, they give the annual electricity consumption in units (for 1600 hrs of usage) for ACs. Now the consumption is more in summers and less in winters, so to get to a right calculation is extremely difficult. But then for the sake of simplicity we just divide annual consumption given by 1600 to get hourly consumption. For Hitachi Kashikoi 5400 it is 793 units in 1600 hrs, so about 0.5 units per hour. Let's be pessimistic and take 0.6 units per hour. IN that case for 60 days your consumption would be 0.6 x 8 x 60 = 288 units. And at Rs 6.6 your bill would be 288x6.6 = Rs 1900. So you would save about Rs 2500 per billing cycle. But buying this would also be expensive. Usually if your annual usage is about 1600-2000 hrs, going for BEE 3 star inverter AC is also fine. So you may find Hitachi Kashikoi 3300i or even Waza 3300 would be more value for money in such case. If your usage is more than 2000-2500 hrs, then you must go for BEE 5 star rated inverter AC. Otherwise you will not be able to make out the return on investment. If you do not care about ROI then going for Kashikoi 5400i is always the best.

For the 2nd room, the ideal tonnage would be 1.2 ton. If the usage is only at night then 1 ton AC would also be fine. Or even 1 ton inverter AC because 1 ton inverter AC can stretch to 1.2 ton. What will be your usage of this AC?

105

Thanks for the clarity, Abishek.

The 75% calculation that I mentioned was for my old fixed cost windows AC. Should I consider any other threshold value (instead of 75%) for my old AC?

The 2nd room is for single occupancy. It will be used only at night time for 5 hours a day.

106
Abhishek Jain (Mod)

Usually 70-80% is considered as ideal cycle time assuming the AC is rightly sized. So 75% is not bad.

You can go for 1 ton BEE 5 star rated AC for that room. You can look at these:

Blue Star 5HW12SBTU or 5HW12ZBRTU or 5HW12ZBWTU

Hi
I want to use 1.5 ton dual inverter ac for 90 square feet room with ceiling height of 8 feet , the room is on first floor, with another floor on its top, one side of the room has 3 glass windows. My question is owing to the small size of the room, will there be any wastage of electricity, if 1.5 ton dual inverter AC is used instead of 1 ton AC. Looking forward for your reply. Thanks

108
Abhishek Jain (Mod)

Hi Mohsin,

1.5 ton would be highly oversized for 90 sq ft room. I would suggest that you go for a 1 ton AC. That would be better. Being inverter AC, there won't be wastage of electricity as it can adjust to the needs of the room. But being highly oversized, it can lead to ineffective removal of humidity if not anything else. If you are in a dry city, then you may go for it.

109

Hi Abishek. Your comments have been very educational. But I'm confused about this "ton" terminlogy. Inputting my room area in your calculator, it recommends a 2ton AC. Is that the same as a 2hp AC? Admittedly I don't live in India, but where we are the AC's are rated in hp on their websites. Kindly clarify the confusion. Thanks.

110
Abhishek Jain (Mod)

1 Ton is equal to 3504 watts of cooling capacity. And 1 Hp of cooling capacity is about 2550 watts of cooling capacity. So you need about 7000 watts of cooling, which is about 7000/2550 = 2.75 Hp of cooling.

111

Hi Abhishek sir,
i need your views to select between Blue Star 5HW18SBTU and Mitsubishi MSGK18VA, please help me out to go for the better one.
please also let me know about r22 refrigerant availability after 2020 as i heard that i will be difficult to get it after 2020 and total ban from 2030 and its cost also going to shoot up after 2020 due to some environmental restrictions on r22. depending on your views on r22 availability i want to consider Hitachi RAU518AVD model.
please share your views on above 3 models and suggest which one should i consider.
Thank you.

112
Abhishek Jain (Mod)

Hi Shekhar,

Blue Star 5HW18SBTU is certainly the better one, because it has higher cooling capacity and lower power consumption. And thus EER also is much better. And Blue Star is a premium Indian brand. So I think it is a better choice.

As you rightly mentioned, complete phaseout is by 2030. However, how the dynamics play by then is not known. Pricing is a game of demand and supply so I cannot say how costly would it be by then. But as per the plan 2030 is complete phase out.

I think Blue Star 5HW18SBTU is a fantastic model and you should not consider Hitachi RAU518AVD.

113
Shekhar Daniel

Thank you for your suggestion Abhishek. One last question, if Blue Star 5HW18SBTU is compared with Daikin ATF50SRV162 / FTF50SRV162 / DTF50SRV16, which model would be a better choice ? Does Blue Star comes with copper ?

114
Abhishek Jain (Mod)

Hi Shekhar,

Blue Star is a bit more efficient as its EER is 3.8 as compared to 3.65 of Daikin models. But then that difference is not huge. FTF and ATF models have PM 2.5 (pollution) filters as well. But then Blue Star model has 7 different types of filters (for bacteria, virus, etc). Both these brand have copper models. Blue Star additionally has corrosion protection on its models. Difficult to choose one as Daikin is a premium Japanese brand and Blue Star is a premium Indian brand. I would go with Blue Star in this case.

115

Hi Abhishek
In Blue Star 5HW18SBTU its showing two options as:
1. Long life MCHX Condenser with 5 years warranty.
2. Anti-Corrosive blue fin copper condenser with 1 year warranty.
I am confused for which one to consider, 5 years warranty or anti corrosive blue fin. Please suggest the better option to consider.

116
Abhishek Jain (Mod)

I think Anti Corrosive Blue Fin option would be better.

117

Thank you so much for you valuable views and suggestions Abhishek... except on this platform i could not get this kind of help anywhere else, as suggestions/views to select an AC/Air cooler... not only that but also many other valuable knowledge/education on various topics through articles on bijlibachao.com
keep your great work going...
will surely update you after purchasing my AC.

118

Hi Abhishek
I am planning to buy a Split AC 1.5 ton for my living room , sun facing, top floor. I have previous experience with samsung and General. With samsung i have a very bad experience but with general its been almost 15+years and i didnt have any single complaint.
Now i looking for a AC. I have searched an O General AC asga18jcc and it will cost around 55k which is very costly.
Please suggest me a split AC 1.5 ton copper condenser, inverter AC. Range 30K to 40K

Hi Prateek,

You can look at any of these:

LG JS-Q18SUXD (Amazon Link: http://amzn.to/2oMG2Le )

LG JS-Q18AUXA (Amazon Link: http://amzn.to/2oMjWqB )

Godrej GSC 18 MINV 3 RWPM (Flipkart Link: http://fkrt.it/4zbS3TuuuN )

Whirlpool EZ FANTASIA INVERTER COPR 3S (1.5 T) (Flipkart Link: http://fkrt.it/xM!vQ!NNNN )

These are all copper condenser Inverter ACs.

120

Query with a clarification about LG JSQ18AUXA 3.68 or 3.86 ISEER -- missed to sign off. Lakshmi.

121

Hello Abhishek,
Thank you for all your research and patient advice on this website! Reading several pages and comment threads has helped me understand a lot regarding AC choices. As per your calculator I need a 1.5 Ton AC (for 1.3 cooling); I prefer copper condensor; and even though usage will only be 3-4 hrs per day for 4 months in the year, since Mumbai has high power tariffs I feel an inverter AC may be the wisest choice for me (would you have any feedback on this?). Based on your Top Ten 1.5 ton 3* inverter AC list, I'm trying to decide between Bluestar 3CNHW18TAFU, Voltas 183VEY, Voltas 183VIY. What would you recommend, in terms of energy efficiency, cooling capacity and features?

My second rung of choices included LG JSQ18AUXA, Bluestar 3CNHW18NAFU, Bluestar 3CNHW18CAFU. Your site shows this LG model having a 3.68 ISEER, but I think in a response on some thread you mentioned that this model of LG does not appear in the BEE/ ISEER database. And the LG website says this model has a 3.86 ISEER. I'm confused; could you please clarify this for me? And from this second rung, what would you recommend in terms of energy efficiency, cooling capacity and features?

Thank you for your time!

122
Abhishek Jain (Mod)

Hi Ellkaye,

Based on your selection from the top ten list, I would say Blue Star 3CNHW18TAFU with ISEER of 3.77 would be the best. In terms of cooling capacity, energy efficiency and features, this would be the best model as it has loads of filters for cleaning the air. Blue Star also has iFeel sensors which makes the thermostat available on the remote control rather than the indoor unit. So all in all this would be a better choice among the 3.

Your second question points to a bigger challenge that I face regularly. When I talk to BEE, they say that their data is perfect and they have published it on the website. However, when I do a data comparison between what the manufacturers are selling and have published, I get a different information. At Bijli Bachao we have tried working with different parties to get this resolved, but then it is difficult to get a lot of parties on the same page. So lot of LG models are not registered on BEE website (and I am not sure who is at fault here). But what manufacturers report is data that they get from NABL accredited testing labs, and the same is used to give BEE star rating.

For AUXA, the value mentioned on BEE database is 3.68, whereas that mentioned on LG website is 3.86. If I ask LG they will say it is 3.86 whereas it is different with BEE. Difficult to say what is the correct value, but I think I would trust the manufacturer on this. They also have the SU and TU series that are copper. However, the data on BEE site say 3.68 for SU series as well. I think if Bluestar 3CNHW18TAFU fits in your budget, then that would be a good choice.

123

Thank you for that explanation, Abhishek. It's a relief to have a platform like this, with accessible technical information and encouraging users to understand more. I'll go with your recommendation. And kudos for helping us figure these things out with all the challenges you face!

124
Abhishek Jain (Mod)

Great! I am glad that you found Bijli Bachao useful. Thanks for the appreciation :).

125

And just when I felt I had it all figured out, now I'm going round in circles of doubt! I wonder if I ought to reconsider my need for an inverter AC entirely. For 3-4 hours daytime usage for about 4 months in the year, not top floor, having a west-facing window about 33 square feet, what would your recommendation be?
I apologize for this googly, and many thanks for your patience Abhishek.

126
Abhishek Jain (Mod)

Your usage would be about 600 hrs a year, which is not much. You may even go with BEE 3 star non inverter AC. But at least go for BEE 5 star non inverter (just for the sake of saving electricity) :).

127

Thank you for your response, Abhishek! So based on your Top Ten 5* Fixed speed ACS, I looked up Bluestar 5HW18SBTU, 5HW18ZBRTU, 5HW18ZBWTU, and they have the exact same technical specifications and features (unless I missed something). Would you know if any among these is better than the other two? Thank you.

128
Abhishek Jain (Mod)

The difference between these three is just in the color of the indoor unit. There is no other difference in features.

129

Thank you Abhishek, I'll go with one of these. I really appreciate your advice. And vast patience!

130

Hello Sir,
I am planning to buy 1.5 ton inverter ac. i have selected three models 1) daikin jtkm50 5 star ,2) Daikin jtkp-E 4 star anti corrosion model 3) bluestar 3cnhw18cafu 3 star with blue fin copper condenser.So my questions are as follows
1) Choice no 2 has anti corrosion coating and Choice no 3 has blue fins condenser so out of these which would be better
2) Also new daikin models have become compact and they are using dual flaps for cooling .will it give efficient cooling and what would be the lowest temperature that can be set in all of the above models.
3) I am going to install my compressor where it would face direct sunlight so will it consume more power or give less cooling.
4) is it worth to buy inverter ac as i am going to use it for max 6 months a year.my usage would be for 2 to 3 hrs at afternoon and 5 to 6 hrs at night .i have heard that inverter ac will be beneficial if they are used continuously for 8 to 9 hrs.
5) Is bluestar a reliable company.most of the people have suggested me to go for daikin ac as they have better quality and are more durable than bluestar

131
Abhishek Jain (Mod)

Hi Harsh,

Here is my response:

1) Both will be good. Blue Fin is a good anti corrosion coating. Daikin also uses similar coating. So both will be equally good.

2) Cooling depends on cooling capacity of the AC. Dual flaps etc are just the methods to achieve it. Look at the cooling capacity (in watts) of the AC which is mentioned on the AC specs. The AC having higher cooling capacity will cool better/faster. Usually the lowest temperature setting is 16 or 18 degrees, but then AC does not really cool that much. It depends on cooling capacity of the AC and the heat load of the room. To give you analogy imagine a tank full of water that need to be emptied. And you but a tap to connect to the tank and drain out water. Similarly you have a room full of heat and you buy an AC (just like tap) to drain out heat. Every tap has a maximum flow rate and similarly every AC has a cooling capacity. Your room is full of heat and it has heat coming in through the walls and other sources. And AC just like a tap is trying to remove the heat. It will achieve a temperature where heat flow balances. To read more you can check this link on how an AC works: https://www.bijlibachao.com/air-conditioners/air-conditioner-work-laymans-explanation.html

3) It is not advisable to install compressor directly facing sunlight. It reduces cooling. And if you want to do so, then go for an AC that has higher operating temperature. Blue Star models can work at up to 52 degrees. Daikin models have less operating temperature.

4) Inverter ACs save electricity even for 1 hour of usage. But then they are expensive to buy and so while calculating economic benefit, one has to look at number of hours the AC will be operated in a year. Many people just apply thumb rule and say it has to be used for 8-9 hrs. But then it is not necessary that it has to be continuous. Also number of hours depends on the electricity tariff that you pay and that varies from state to state. In a place like goa where electricity is just Rs 3-4 per unit, the economic benefit of Inverter ACs is hard to achieve, but in a place like Mumbai where tariff is Rs 11-12, it is easy to achieve economic benefit. However, if you are not looking at economic benefit and just want to save electricity, then inverter ACs can save electricity even in 1 hr of usage.

5) Blue Star is a premium Indian brand. It is certainly quite reliable. Daikin is a premium Japanese company. They are pioneers of Inverter Technology. So I would say quality would be good in both.

132

Hello Harsh !!
Just a quick bell, Daikin JTKM50 is sadly out of stock at more or less everywhere. I went to market last week for JTKM50, and bought CTKP50 (1.5 ton 4 star). I think this information will be helpful to you.

133
Abhishek Jain (Mod)

Hi Prasun,

Thanks for the information. Do let us know your feedback on CTKP50.

134

Hello Abhishek !! Offcourse I will let you know the feedbacks. Let me use it for atleast 1week. It just installed yesterday. :)

135

Hi Abhishek
i have used the calculator above which shows me the below result.
1.5 Ton (For cooling requirement of 1.2 Ton)

I am having the room on the first floor which get direct sunlight from the top.
My usage is on the night only and its 6 hours for 6 months (April-Sept). Can I consider 1.1 ton from Hitachi A/C ?
I am having the provision to easily install the window a/c in that case what you recommend for me.

1. Which one is good for me Window or Split ?
2. do I require to buy 1.1 ton or 1.5 ton for me ?
3. Any recommendation for brand ?

Thanks !!

136

Thanks for your reply,
my budget is 30k approx. Please suggest, windows vs split on the factor of Power saving , maintenance and long life of the product.

Thanks !!

137
Abhishek Jain (Mod)

You can look at these ACs:

Hitachi RAU514HWDD (Amazon Link: http://amzn.to/2qPCRSG , Flipkart Link: http://fkrt.it/!2PH3!NNNN )
Voltas 155 CY (Amazon Link: http://amzn.to/2pnmeh1 , Flipkart Link: http://fkrt.it/!nSAk!NNNN )

In window AC you can look at:

Hitachi RAV513HUD (Amazon Link: http://amzn.to/2pnr8KI , Flipkart Link: http://fkrt.it/TLXtoTuuuN ) .... but the above two split ACs would be far more energy efficient than this one.

138

Hi Abhishek

I am still confuse, that I shall buy the 1.1 or 1.5 ton A/C.

As you mention "it is very important to right size your AC as oversized AC can consume a lot of electricity (in case of fixed speed ACs) and undersize may not cool well enough"

I have a question, if I buy the 1.5 ton A/C for the room size of 9*12 and where roof get direct sun light then 1.5 ton is oversized. Will 1.5 ton A?C consume less Electricity, as the room size is small so the A/C will auto cut early ?
If we take an example, for 1600 hrs of usage in a year BEE star label show 1200 unit, then if the room size is small then will it consume less electricity ?

My Second question is, Can we find the Cooling capacity required for my room ? As there are few models in 1 ton which gives 3300 (approx) cooling capacity and 1.1 ton Hitachi A/C have cooling capacity of 3900. Where as Whirlpool 1.2 ton A/C have low cooling capacity. Can we find the cooling capacity required for me and then I can choose the right tonnage for me ?

Thanks a lot !!

139
Abhishek Jain (Mod)

Hi Praveen,

If the calculator suggests 1.2 ton then the best choice for you is to go for 1.1 ton or 1.2 Ton. The calculator gives a fairly good idea of cooling capacity (although with some assumptions). And 1.2 ton is equal to 4200 watts of cooling capacity. So a number closer to 4200 watts would be the best choice for you. 3900 watts would be good. In fact you will find a lot of 1.5 ton ACs marked as cooling capacity close to that.

Hitachi RAU514AWD (Amazon Link: http://amzn.to/2qavesv , Flipkart Link: http://fkrt.it/tPMA7!NNNN )
Hitachi RAU514HWDD (Amazon Link: http://amzn.to/2r7AL0D , Flipkart Link: http://fkrt.it/tPUFQ!NNNN )
Hitachi RAU514IVD (Amazon Link: http://amzn.to/2ps0Knk )
Voltas 155 CY (Amazon Link: http://amzn.to/2qaAj4d , Flipkart Link: http://fkrt.it/tPclo!NNNN )

would be good for your requirements.

You may even look at 1 ton inverter ACs as they can extend up to 1.2 ton. This would be good if your area is not corrosive.

1.5 ton AC has more refrigerant in it. And in ACs refrigerants go through cycles of conversion from liquid to gas and then back to liquid. It takes heat from the room and liquid converts to gas. Because it has more refrigerant, it takes more heat from the room per cycle. So it overcools the room if the AC is oversized. So to adjust electricity consumption to the levels of a right sized AC, you will have to keep the AC at a higher temperature. If you keep it at higher temperature, then the AC will short cycle (will switch off quickly after running for a very small time). The fixed speed AC does not achieve peak efficiency till it runs for substantial amount of time. So it will consume less electricity, but the efficiency will be low. So the same cooling can be achieved at better efficiency by going for a smaller AC.

140
Abhishek Jain (Mod)

Here is my response:

1) You will find lot better and efficient options in Split ACs. You will find less choices in Window. Manufacturers have not improved technology for window ACs for past 4-5 years. So if you want latest technology then Split would be a good choice.

2) You can go for 1.1 ton AC as well. 1 ton may turn out a bit small in peak summer day time. If your usage is only at night then you can go for 1 ton as well.

3) What is your budget for this AC? I can make recommendation accordingly.

141

Hi Abhishek
When I enter my data in the calculator above its shows the below result
1.5 Ton (For cooling requirement of 1.2 Ton)

What is the meaning of this statement, do I need to buy 1.5 ton or 1.2 ton A/C ?

Thanks !!

142
Abhishek Jain (Mod)

Well the best bet for you is to go for 1.2 ton. But then you will find limited options in 1.2 ton. If your usage is mostly at night, even 1 ton would be good enough. In peak summer day time 1 ton may not cool down to 25 degrees and that is why to be safe we suggest 1.5 ton.

143

Hello Abhishek !! You are doing a great job by helping us. I have some enquiries. Is high ISEER ranking is good or low ranking ? 1 AC have 3.65/3 rating and other have 5.20/5 rating of ISEER (Say Daikin JTKM 50). Then which one will be more energry efficient ?

And mine is 15*10*10 (L*B*H) house with top floor, with direct sunlight at roof and west and south-west. I need 1.5 ton ac. Budget is 45k. Can you tell me which one will be the good choice ??
1. DAIKIN FTHP50
2. DAIKIN FTKP50
3. DAIKIN FTKM50
I also have DAIKIN JTKM50 in my mind. But it is going beyond my budget.
And please if you have any brand suggestion other than DAIKIN, then please tell me. I love Hitachi models, but they are very high in price range. (I'm talking about Other than the fixed speed ones) .
And I'm from KOLKATA.

144
Abhishek Jain (Mod)

Hi Prasun,

Higher ISEER means higher energy efficiency. So Daikin JTKM would be more energy efficient. As for the choice, if you can get Daikin FTKM50 in your budget, then that would be the best and most energy efficient. Else FTKP50 for sure will fit in your budget and would be a good choice.

145

Hi Abhishek, I live in Bangalore where there some power cuts almost every day. I do have an Inverter for the house for power backup during power cuts. I am planning to buy Hitachi Waza 3200i 1 ton ac, so would I also need to buy a voltage stabilizer? Any AC that you could recommend that do not require a stabilizer? Thanks!

146
Abhishek Jain (Mod)

Hi Arya,

In general inverter ACs do not get damaged due to low voltage. But they may get damaged due to power surges (sudden high voltage). In that case going for a surge protector or stabilizer with surge protection would be better. Depends on power quality in your area. You can check some of those on this link: https://www.bijlibachao.com/appliances/voltage-stabilizers-buying-guide-best-tv-ac-fridge-home-guide-india.html

147

Thank you Abhishek for your reply.
It is a modern apartment with circuit breakers in the Master Switch Board. Will it not take care of power surges (in case there is one), like trip itself? If it does, then the AC should be safe from the surge, right?
Thanks!
Arya

148
Abhishek Jain (Mod)

The main purpose of MCB is to protect wiring in your house from burning. MCB measure the current going from the wires and when it is too large for too long that it can result in burning of the wire, it cuts off. On the other hand Surge Protectors do not measure current, but check voltage. When the voltage is extremely high it absorbs (grounds) extra energy and thus protects the appliance. The MCB is lot central and Surge protector is local. A surge protector can act faster to protect your appliance as compared to MCB.

149

Hi Abhishek, I am from Bangalore and I am planning to buy Hitachi Waza 3200i 1 ton inverter AC. Is this a good choice when compared to Daikin FTKH35? Also I stay on the third floor of an apartment, so I was wondering if/how the technician would be able to climb the outer wall of the building to install the AC? There is an AC provision provided by the builder where I can see a socket and a switch, but any other electrical components/wires that I need to be aware of with regards to the installation of this AC (I read somewhere stuff like 1/2, 3/8 pipes)? Please throw some light. Thanks!

150
Abhishek Jain (Mod)

Hi Arya,

Hitachi Waza is certainly much more efficient than Daikin FTKH35. So I think it is a better choice. Brand wise both Hitachi and Daikin are quite comparable. So you can certainly go for Hitachi Waza 3200i.

Also if you do not have access to the outer wall, then you will have to get a metallic platform built and bolted on the outer wall in such a way that the AC can be installed on it and someone can stand on it to do service as well. It has to be strong enough to handle good enough weight. It cannot be standard installation. Someone will have to tie some ropes and climb down a window to bolt the platform on the wall. That is how it is done in most high risers.

Your installer will get the pipes required to install the AC. You will not have to worry too much about it. But then you can check the size of refrigerant pipe diameter on Waza's specs: http://www.jci-hitachi.in/images/products/specifications/spe_1485338828.pdf

151

Thank you Abhishek for your reply. I called in a technician from Reliance Digital to take a look. He suggested that the ODU could be fitted on the terrace (there is just one floor between mine and the terrace). Is this an efficient solution? I understand that this would have easy accessibility for servicing of the ODU.
According to the your calculator, it suggested a 1 ton AC for my bedroom, but the technician recommended a 1.5 ton one after seeing the room (though it does not receive any direct sunlight from top or any side). So, considering I might use this AC to also cool the adjacent Living Room occasionally, do you still think a 1 ton Hitachi Waza 3200i AC would suffice?
I see two 1.5 models in Hitach Waza 3200i (RSG317EAEA and RSD318EAEA). Could you please elaborate the difference and in case I need to go for 1.5, which one among the two would you recommend?
Thanks!
Arya

152
Abhishek Jain (Mod)

It truly depends on what is the recommended max piping size for the model you select. It is less for some models, more for some. For e.g. Blue Star markets that their ACs can work well even with longer piping. If your are planning to go for Hitachi, then check with them on the recommended piping length. Usually longer piping is not very desirable because piping also has to be well insulated. And improper installation can lead to efficiency losses.

If the calculator suggests 1 ton then I would say 1 ton would be fine. Although in inverter ACs oversizing is not bad, so you may go for 1.5 ton as well if you have any doubts. Also a single AC cannot cool two rooms unless there is a good enough air circulation between the two rooms. However, I would not suggest a single AC to cool a long enough space. If you do so (even with good air circulation) then to calculate the right size, you will have to take into account the area of the two rooms.

317 is lesser cooling capacity (5000 Watts) lesser efficiency model (ISEER is 3.71) whereas 318 is higher cooling capacity (5275 watts) more efficiency (ISEER of 3.99) model. However, if you plan to oversize then any of them would be good enough. You can go for the one you get cheaper.
