Electricity Saving Tips For Homes And Offices

Tips to choose the best brand air conditioner

By on January 21, 2014
This article is also available in these languages: hi Hindi

A few days back we published an article on tips to buy an air conditioner (link) and since then we got several requests from people asking for tips to buy air conditioner. Although we covered most things related to technology on that article but there was one thing that we did not cover: which is selection of a brand. And this came up consistently when we discussed about air conditioners with people. The most common statement that we received was “all this is fine, but which brand should I buy?”. At Bijli Bachao, it is our consistent effort to be impartial in our tips and ideas and we try to avoid naming brands. We make sure that our suggestions talk more about technology rather than endorsing a specific brand. So we will try to answer this question as pragmatically as possible.

Air Conditioner

There are multiple bands of Air Conditioners available in Indian market and it all makes it confusing for people to decide on which brand to buy. Although we had published an article in the past covering various brands of air conditioners and the number of energy efficient air conditioners that they offer (link). But the list is more on numbers, market share and BEE star rating. We also have a link that lists the top ten air conditioners by energy efficiency (link) but that is again only on BEE star rating. When someone decides on a brand, the decision goes beyond numbers and is equally qualitative than quantitative. Air Conditioners can contribute about 30-40% of electricity costs in a household so it is very important to make a right choice while buying one. So here is our analysis:

Air Conditioner brands that are known for their air conditioning technology

There are some brands that are known for their Air Conditioning technology. These companies have done extensive research on the subject of cooling and provide the best in class technology. Their models are energy efficient and also last longer than most air conditioners. In few of our energy audits, we have observed that models of such brands give higher efficiency even when they are quite old (obviously they need to be maintained well as well). But better technology makes them last longer and provide better efficiency.

Most such brands are expensive to buy. So the capital cost is high, but the efficiency factor makes them pay back for themselves in terms of energy savings as well as longevity. The caveat is that they may not have service centers available in smaller cities, which may make maintenance of the air conditioner a little difficult.

Generic brands that are into multiple appliances

There are some brands that sell a lot of kinds of appliances and are generic. They may not be expert in cooling technology, but the models that they offer are above average. Because of their focus on multiple things, their models may not be the best in the market, but they provide very competitive pricing. Models of these brands are slightly cheaper than those of the brands with “best technology”. These may turn out to be value for money if the use of air conditioner is not very high.

Many such brands have larger market penetration and thus their presence is there in remotest of locations in the country. Getting access to their service is quite easy, and thus regular maintenance of these models is possible.  Many of these brands have energy efficient models but the longevity of those will not be as good as the ones with “best technology” brands. But as said, they can be great value for money if the use is less.

Inexpensive brands

There are some brands that provide cheapest models in the market. It is an observation that they hardly focus on energy efficiency and thus most of their models are low on star ratings. These brands may provide inexpensive models but the lower energy efficiency increases the electricity bills. If they use is high, they can significantly increase your electricity bills. As we discussed in one of our previous articles that it is not just the capital cost that is important while buying an appliance, it is also the operating cost that is important (link and link). Most appliances consume more money during their operation than while buying, so it is a factor that one needs to keep into consideration. If you are really challenged with money and do not have any option then buy an inexpensive brand, but keep a note that it can increase your electricity bills.

Finally going for a brand also has a lot of emotional factors and people prefer buying a brand because of their good experiences in the past. And that also matters a lot. The guidelines that we have given above can help you identify with a brand, but ultimately it is your brand preference that will make you choose one. It is good to keep one thing in mind that an AC bought will be with you for almost 10 years, so make the right choice keeping in mind all the costs involved.

    Dear Mr. Abhishek
    I want to buy an AC for my shop of size(10*15)sqft which type of ac should I buy as well as on wch brand should I concentrate

    • Abhishek Jain says:

      Hi Prateek,

      There are several factors that one need to consider while buying AC:

      1) Tonnage of AC: Depends on several factors, but primarily on size of room, city where you live in, window sizes, people in the room. Oversized AC consumes more electricity, and undersized does not cool properly.

      2) Star Rating: Choice of BEE 5 star/inverter tech or a lower rating depends on your usage of AC. If your usage is more than 1000 hrs per year (with traiff more than Rs 5), it is better to go for higher efficiency models. Benefit of inverter tech is that it is a variable tonnage AC and as the tonnage requirement is different every month and every day, this AC auto adjusts to the needs and thus saves electricity.

      3) Brand: Some brands offer better reliability/technology and some have better service network. One has to factor in both. Once you have decided on star rating, the most efficient models from good brands can be selected.

      If you provide us with more details as in which city you are in, what is the size of your room, which floor they are on, is there any floor above it, are the walls exposed to sun, usage in hours per day and months per year, and approximate budget, then we can recommend you something

    Dear Mr Abhishek,

    Good day. I am planning to buy ACs seeking your guidance.
    I am from Calcutta and need to buy two ACs for two rooms (12x14x10ft) on top floor (both ceilings exposed to sunlight). One room gets direct sunlight almost through out every morning & day. The other room does not get any direct sunlight. Each AC will be used around 9hrs / day x 7 months (around 1800 hrs yearly). Here cost of electricity (CESE Calcutta) per unit is probably Rs 8.
    While selecting please consider well known branded, value for money products and availability of after sales service – directly by the company.

    I wanted to know the followings from you:

    1. How many years an AC usually work (considering similar conditions as mentioned above)?
    2. Should I buy Inverter AC or BEE Started AC?
    3. Should I buy ACs with same capacity for both the rooms?
    4. While selecting ACs which features are desirable & which are actually not so important? Eg. Auto cleans? R410a? Date of MFG? etc, etc.
    5. Please suggest specific model numbers.

    It would be great if you could mail your reply to [email protected] as well. Thanking you in anticipation.

    Rgds,

    • Abhishek Jain says:

      Hello Mr Jaiswal,

      It will be best if you go for 1.5 ton inverter AC for both the rooms. Here is my response to your questions:

      1) AC should usually work for 10-12 years. That should be average life of an AC.
      2) You must buy Inverter AC looking at your usage.
      3) Yes 1.5 ton inverter AC should work well for both the rooms.
      4) Auto Cleans is good. But that does not mean that it will not require regular maintenance. Auto Clean can surely make sure that the performance of AC is good. R410 is the most commonly available gas in inverter ACs.

      You can look at these ACs:
      Hitachi Ace or Kampa inverter 1.5 ton
      Daikin FTKM50PRV16
      Samsung AR18HV5DAWK
      LG BS-Q186C8R6
      Sharp AH-XP18PHT, AH-XP18PMT, AH-X18PET, AH-XP18MV
      Samsung AR18HV5NFWK

  3. Prabhu says:

    Hi Abishek,

    Thank you for giving us a greater insight about ACs, could you please kindly advice us to choose one of the foillowing Acs based on energy efficiency
    and for long running.

    our room size is 125 sqft and the usage would be 8 hrs everyday in the night, we are from chennai. recently we heard about Toshiba but we could not any valuable review about it.So please advice which one to choose.
    1. Toshiba
    2. Carrier
    3. Ogeneral

    • Abhishek Jain says:

      Hi Prabhu,

      You need 1 ton AC for your room. The brands you have chosen are all good on technology/reliability. General ACs are generally considered quite sturdy, however their numbers on efficiency are not that high. If you are looking for most efficient AC amongst the three brands then I would suggest going for Carrier Superia 1 ton AC or as a second choice you can consider Carrier Estrella 1 ton AC or Toshiba RAS-13N3AX-IN. The Superia series has EER of 3.58 and is a 1 ton AC. Estrella and RAS are 1.1 ton AC with EER of around 3.35 and 3.4 respectively. For night usage Superia would be perfect and would consume low amount of electricity.

      • Prabhu says:

        Hi Abishek,

        Thank you very much for your prompt reply. You are really doing a great job by sharing your knowledge with others.

        The main factor we are looking for is the maximum air throw as it needs to cover the full 14ft length of our room, while checking upon that we found the carrier’s CFM is lesser than other two ac’s listed above.

        Could you please clarify us on the above factor and do we really need to worry about CFM values ??
        Also will carrier superia be able to cover the 14ft distance as the cot and the ac will be two extreme ends??

        Thanks many in advance.

        • Abhishek Jain says:

          Ideally an AC should be kept close to the area where cooling is required. However you can always switch on the ceiling fan to circulate the cold air in the room. The added benefit of ceiling fan would be that you would feel quite cold at lower temperatures and you can comfortable run the AC at temperature of 25-26 which can also help you save some electricity. Also CFM values are related to tonnage. Superia is 1 ton and others that I mentioned are 1.1. So it does not matter. The 1.1 ton AC will cool faster (as it has higher cooling capacity and CFM) but will also consume more electricity to do so. For optimal cooling as well as electricity consumption, Superia would be good.

    i have buy a split ac toshiba inverter 1.5 ton. when its push the off button in remote its not off and goes to timmer pont and run very slow. so many times service man came but i not find the reason

    • Abhishek Jain says:

      Hi viswanath,

      It should not happen like that. When you push the off button it should shut down completely. There is no reason for it to remain on. Also there is very little that I can help you remotely. You will have to depend on Toshiba technical support team to help you.

  6. Karan says:

    What are your thoughts on Voltas 1.2 Ton 5 Star 155 CY ?i have area of 150 sq.ft. in Mumbai. Also is their much difference between 3 star vs 5 star split AC in low usage scenario? Bought it for 25000 from online site (installation pending) & main unit’s power cord doesn’t have plug.Is it normal???Any Help would be great.

    • Abhishek Jain says:

      Hi Karan,

      1.2 ton is the right size for 150 sq ft in Mumbai, so your Voltas AC should work well. The main unit’s power cord typically does not have plug because the companies are not sure as to how long will be the cord. Length will depend on where the unit is installed and where the power source is.

      As far as difference between 3 star and 5 star is concerned. 5 star AC would be 15% more energy saving than 3 star AC. However the cost savings that you achieve by using the 5 star AC can cover extra money that you pay for buying it only if the usage is substantial. In Mumbai the tariffs are quite high. So we typically suggest people to go for BEE 5 star rated AC if usage is more than 600 hrs a year.

    Hi ,
    I would like to buy samsung iinverter ac 1.5 ton AR18HV5NFWK
    local ac machanic say its made of aluminium and its not good what should i do i need most power saving should i care his words

    • Abhishek Jain says:

      The problem with old aluminium models was that they used to corrode easily. But in many brands these days the condenser fins are coated with anti corrosion protection. Even this model from Samsung is coated with anti corrosion enamel which makes it quite durable. In fact this model comes with triple protection from: 1) voltage fluctuation 2) surge 3) corrosion. You can check the link: http://www.samsung.com/in/consumer/home-appliances/air-conditioner/split-air-conditioner/AR18HV5NFWKNNA . I think it is a safe model.

      • harsha says:

        does we get big difference in cooling between aluminum and copper .Do i get the same coolin as ogenral 1.5 ton 5 ssta.

        • Abhishek Jain says:

          Cooling depends on cooling capacity (or tonnage) of the AC. You should look at the cooling capacity value on the BEE label. Higher the cooling capacity, faster the cooling. Cooling is independent of Aluminium or Copper. Aluminium and Copper are important from durability perspective. O General BEE 5 star rated AC has (fixed) cooling capacity of 5100 Watts. Samsung AR18HV5NFWK has nominal (or base) cooling capacity of 5000 watts. Also please note inverter ACs have variable tonnage or cooling capacity. Although the nominal cooling capacity is 5000 Watts, it can certainly extend itself beyond it if needed.

  8. preeti says:

    I want to buy a window ac for my bedroom 8.5×19 sq ft. Sunlight falls on the window from 1 pm to 6 pm. I stay in thane. Usage would be 5-6 hrs at night and 2-3 hrs during day during summer.

    My budget is Rs. 25000. Please suggest an ac with optimal power saving and durability in this range.

    • Abhishek Jain says:

      Hi Preeti,

      You need 1.5 ton AC for your room. It will be difficult to get BEE 5 or 4 star window AC in 25K. You can get BEE 3 star AC. You can look at these:

      VOLTAS 183 MY
      LG LWA5CS3F
      VOLTAS 183 DY
      LG LWA5BP3F
      BLUESTAR 3W18LB

    I want to buy 1 ton Split AC for my room in mumbai.
    my normal consumption is daily 2-3 hrs during night and during summer 5-6 hrs.
    I am looking for Hitachi RAU312HUD.
    But i heard very bad reviews of Hitachi in service on net.
    Please suggest me model of Carrier or any other brand with good service and features.
    Budget around 35k.

    • Abhishek Jain says:

      Hi Nikhil,

      You can go for any of the Blue star BEE 5 star 1 ton split AC or Daikin FTF35PRV16. They should cost you less than 35K. In Carrier you can go for Estrella series.

  10. dr.Vivek Bhalerao says:

    Which split Ac has most efficient filters of bacteria,Virus,smoke and foul smell?

    • Abhishek Jain says:

      Hello Dr Bhalerao,

      We do not have any data on filters and their effectiveness. So I would not be able to help you much on this.

  11. Prasad says:

    Hi Abhishek,

    Thank you for running a gr8 blog!!!. Very educative.

    I am planning to instal 5 star inverter tech split A/Cs in my house in Thane, Mumbai. I am convinced about your points about efficiency of star rated inverter tech A/Cs suggested in your blog. Three bedrooms (on 25th floor with two floors above) of approx 150 sq ft, 130 sq ft and 110 sq ft respectively. Sunlight for approx 3-4 hrs from the east. Will use in the night 6-8 hrs and 1-2 hrs by day. Could you please suggest tonnage and brands please. Thanks.

    • Abhishek Jain says:

      Hello Mr Prasad,

      You need 1.2 tons of cooling for 150 sq ft room, 1 ton of cooling for 130 sq ft room and 0.8 tons of cooling for 110 sq ft room. If you go for inverter AC then you need 1 ton inverter AC for 150 sq ft room, and 0.75 ton inverter AC for the other two rooms. In Thane if your usage is more than 800 hrs/year then you should go for BEE 5 star rated AC and if it is more than 1300 hrs/year then you should go for inverter tech AC. Let me know your usage and the depending on that I can suggest you some brands and models.

      • Prasad says:

        Thanks for your prompt reply. I plan to use the A/Cs for more than 1000h. Will 1 ton split inverter a/c be adequate for 154 sq ft room? Or shall I go for 1.5 tons?

        Regards,
        Prasad

        • Abhishek Jain says:

          1 ton split inverter a/c should be adequate for 154 sq ft room in mumbai. Average high temperature in peak summer in Mumbai is around 34 degrees, unlike places like Delhi and in North where peak summer temperature is 46 and beyond. So the thumb rule of 1 ton for 100 sq ft does not work in Mumbai.

        • Prasad says:

          Thanks Abhishek. And could you suggest me a few brands please? 1.2, 1 and .75 tonne 5 star inverter.

    Hi Abhishek,
    First of all congratulations ! You are doing a terrific job via your blog.
    I am from Daman and the dealers that I have visited stock more of Lloyds, IFB etc. and heard that these does good nos. in this region. What is your take on these brands – have not seen you recommending these. Other brand recommended by local dealers is Panasonic. I am looking for a 1.5 T split for one of my top floor rooms. We generally use it only for cooling the room initially for an hour or two. Also the dealers recommend going for ACs with copper tube as the air around here is humid and salty. Would need your advice on this too.
    Thanks !

    • Abhishek Jain says:

      Hello Mr Nair,

      When we make suggestions our first criterion is to pick up the most energy efficient AC in a specific band (Inverter, BEE 5 star, BEE 3 star) based on your usage. Then we look at brands that are most popular and finally we also look at the budget that a person has. Now Lloyd and IFB are not the most popular AC brands and neither do they have the most energy efficient models in various bands thus they do not appear much in our recommendations. Panasonic is a good brand, quite popular as well. As for corrosion protection, the best approach is to go for a model that has anti corrosion treatment done for the coils (be it copper or aluminium). There are very few brands that offer copper tubes and Carrier is one of them. Most others have pre-coated aluminium (also known as blue fin). Panasonic has blue fin condenser which is specially made to protect it from corrosion.

      Now I cannot comment on 1.5 ton sizing of your AC as I cannot do that without knowing the size of your room. However if your usage is very less then you can go for a BEE 3 star rated AC. You can go for Panasonic if most other brands are not available in your area. Blue Fin condenser in panasonic would be good for protecting against corrosion.

      • Biju Nair says:

        Hi Abhishek,
        Thanks for the prompt response.
        I didn’t take the measurements as 1.5 T was recommended by the dealer service person who had come for servicing another AC that I have. Will measure and send the dimensions to you tonight for confirmation.
        Is blue fin a safe bet for coastal regions? One dealer I met is a Samsung dealer for other appliances, but he doesn’t stock Samsung ACs as they do not have copper condensors. As per him he stocks only ACs that have copper condensors like Blue star, Lloyd & Carrier as he doesn’t want to face customer complaints on corrosion. Among these the Blue star model is 6K costlier in comparison to the Llyods model and available Carrier model is 2 star only. The power tariff at Daman in the peak band is only 2.55 Rs per unit.
        Among the Panasonic models what is the difference between UC18 & YC18 series? The cost of the latter is about 2K more than the former. (BTW the guy who sells Panasonic thinks blue fin is copper).
        Regards!
        Biju Nair

        • Abhishek Jain says:

          Hello Mr Nair,

          Even Bluestar has blue fin condenser. And blue fin condensers will work great in costal regions. Carrier is the only brand that I have seen has 100% copper. These days many guys sell blue fin as copper or sometimes they call it alloy. However the terminology does not matter, all I can say is that it will work great in costal regions. YC series have more air filters for better indoor air quality whereas UC series does not have that many filters. In general YC model has more features. Your tariff is quite less so I think BEE 3 star rated AC would be good for you. You can go for Blue Star as well if you get a good deal.

          • Biju Nair says:

            Hello Abhishek,
            Thank you for the quick response. The room size is 16*11 with a portion going for a 5*6 toilet. The room has 2 windows on the east side wall, which receives heat during the first half of the day. However, the room is generally occupied at night only. Please check whether 1.5 ton is correct for this.
            Regards,
            Biju Nair

          • Abhishek Jain says:

            Hello Mr Nair,

            1.5 ton is right size for a 16×11 room in Daman. The average high temperature is Daman is only about 35 degrees. So the size looks fine to cover peak summer day time.

    Dear Abhishek,

    I am staying in Bhopal. I am planning to buy an Air Conditioner for my first floor bedroom 14 X 11 sft of my duplex row house. It has three doors, one towards balcony on the east along with a window , second one is the entrance to the room from landing from staircase on south and the last one towards the bathroom on the west. The room is having a 7 x 6 bed, a steel almirah 6 x4 x 3 and 21 INCH TV along with 4 drawer wooden cabinet as stand. The room is receiving direct sunlight as there is nothing more on the terrace.

    From my side, I have researched on SAMSUNG AR18HV5NFWK, VIDEOCON, VOLTAS, BLUESTAR(on a suggestion from a friend, but on internet, I found quite few complaints), DAIKINI and O’ GENERAL. I have be told that O’GENERAL & DAIKINI are best and also costly. Also inverter AC are equal to a presumed 7 star AC. For my usage patttern, a five star AC is being suggested as inverter AC is needed only in case I a happen to run it the whole day and night and also save on the capital cost. I am interested in a five star or inverter AC from electricity bill point of view, as I am paying a monthly bill of RS 1300/- plus, already. We are presently using the largest Nagpur type desert cooler, VIYAY make for this room, being used since 11pm to morning 7am approximately. This will be the first AC in our household. All along I personally was not interested in an AC as getting habituated to it will make me use AC every where. But now I have to give in to my wife’s demand for the AC.

    I have tried to give you the whole picture, this moment. Hope, I have ‘not bored you with my exhaustive question, idea is to give you my research to enable me to get the best advice from you.

    • Abhishek Jain says:

      Hello Mr VENKATESWARA RAO,

      The choice of inverter or non inverter depends on your yearly usage of AC. We typically recommend people to go for BEE 3 star split AC if usage is less than 1000 hrs per year and price of electricity less than Rs 5 a unit. If usage is between 1000-1500 hrs per year, then we suggest going for BEE 5 star split and beyond that Inverter Tech split AC. This is for 3 years payback for the extra money you pay to buy the appliance. With each star rating increase, the energy saving potential increases by 7-8%. Inverter tech of same EER are 15-20% more efficient than BEE 5 star rated AC. Also the cost differential between 3star and 5 star is about Rs 5000 and similarly between inverter and 5 star is also about Rs 5000.

      You can read more about inverter technology over here: https://www.bijlibachao.com/air-conditioners/air-conditioners-with-inverter-technology-can-help-save-electricity-ac-india.html

      As per my calculations you need 1.7 tons of cooling for your room. In that case if you go for inverter AC you need 1.5 ton inverter AC for your room. Below are some of the most efficient (energy saving) 1.5 ton inverter ACs:

      Hitachi Ace or Kampa inverter 1.5 ton
      Daikin FTKM50PRV16 or FTKP50PRV16
      Samsung AR18HV5DAWK
      LG BS-Q186C8R6
      Sharp AH-XP18PHT, AH-XP18PMT, AH-X18PET, AH-XP18MV
      Samsung AR18HV5NFWK

      Sharp and Samsung would be the cheapest (about 42-45K) in these. Now as you have not used AC till now, let me tell you that if you go for BEE 5 star rated AC it will add about 1.2-1.3 units per hour on your electricity bill. For 8 hours it would be about 10.4 units. In MP the cost of electricity is about Rs 6 per unit. So in a day it will add Rs 62-63. Inverter AC would use about 0.8-0.9 units so will add about 6-7 units. In fact the efficient ones would be a bit lesser than that. So please make a decision based on your usage.

    Hi Abhishek,

    Went through some of the posts here and you seem to be giving very good advice. It is also nice that you reply so promptly.

    I stay in Bangalore. I need an AC for my bedroom (164 sq ft), which is south-west facing. Ours is a corner apartment. We get a lot of sun throughout the day since we are on the top floor. Being in the south-west we get a lot of sun in the room from 2 pm – 6 pm.

    There are only basic electrical appliances in the room, nothing major (no TV, etc). Please advise which brand will be best suited in terms of tonnage/price/power consumption/inverter etc. We need it primarily for 4-5 months during peak summer.

    Thanks!

    • Abhishek Jain says:

      Hi Nupur,

      You need 1.5 tons of cooling for your room. I assume that you need AC only for about 8 hours a day during summers (4-5 month). Which means about 1000-1200 hrs of usage. Considering tariff in B’lore I think BEE 5 star rated AC would be good enough. You may go for inverter AC if your usage is more. You can look at these ACs:

      BEE 5 star 1.5 ton ACs:

      GODREJ GSC 18 FG 6 ONG or GSC 18 FG 6 WNG
      HITACHI RAU518HUDDZ or RAU518HUDD
      LG LSA5AP5M or LSA5ES5M or LSA5MP5M or LSA5NP5F or LSA5SP5M
      SAMSUNG AR18HC5EXLZ or AR18HC5TXNC or AR18HC5TYUR

      1.5 ton inverter ACs:

      Hitachi RAU019EUEA or RAU018IUEA
      Samsung AR18HV5DAWK or AR18HV5NFWK
      Daikin FTKM50PRV16
      Panasonic CS-TS18PKY
      O General ASGA18JCC

    APPROX 8HP IN VRV
    AND 9 TON IN SPLIT AC REQUIRD
    ONLY 3 TON WAITING AREA (cassetee type )as i am planning for FALSE CEILING aND 1.5 TON AC IN LAB -WILL WORK FOR MORE THEN 1500 HRS/YEAR
    rest 2 ac(1.5 ton ) will work for 1000hrs/year
    rest 2 ac(1.5 ton)will work for 600 hrs/year
    NOW TELL ME SHOULD I GO FOR VRV OR NOT
    if not then i am advised for
    inverted ac where usage is more then 1500 hrs then 2ac -one invertor cassete 3ton and one inverter 1.5 ton cassete or split
    remaining two-5 star split and other two where usage less 3 star split ac
    THERE IS DIFFERENCE BETWEEN COST VRV (APROX 5 LAKS) AND NON VRV (4LAKHS)
    so what should i opt
    SECONDLY WHICH BRAND FOR VRV and which brand for non VRV

    Thank you so much
    Dr Sharma

    • Abhishek Jain says:

      Cost of VRV looks really high. Putting inverter split ACs will be much cheaper (as a 1 ton inverter AC would cost about 36-37 K and 1.5 ton would cost about 45 K). I would suggest that you look at Daikin or Hitachi Split Inverter ACs. That will come out much more economical for you.

  16. Ritesh says:

    Hi, need a ac for 100 sqft room on 12th floor & have a floor over it.. Will use it for 10 months in a year for 7-8hrs in night.. Have a glass wall on one side facing south so no sunlight comes directly… Want to a buy ac with copper coil and less taxing on pocket on energy bills… Also I stay in a rented place so might shift after after 2 yrs so don’t want to install ac with high installation cost…. Will appreciate your guidance

    • Abhishek Jain says:

      Which city is this for? Installation cost should be similar for all ACs. If you plan to shift soon, then going for 1.5 ton inverter AC would be good. Carrier has models that are 100% copper. It’s Superia range has the highest energy efficiency. Kurve is the other inverter AC range.

  17. Dipak Vyas says:

    Am planning to have AC for our drawing room, which is L shaped. The rectangle is for sitting area measuring 204 sq ft (17ft x 12 ft), and dining area 90 sq ft( 9x 10).
    Next to this is staircase goes up ( two storey). Drawing room wall facing south.There is covered parking in east and garden on west side wall.
    My question are
    1. what capacity of AC should i put here. is one 2 te is good or two Ac with 1 tone each is good?
    2. It is necessary to close the sides towards Staircase to contain the cooling? just wondering weather cold air travel up or down?
    3. What AC do you recommend here normal Split ac or inverter AC and your pick from brands available.

    Thanks;
    Dipak

    • Abhishek Jain says:

      Hello Mr Vyas,

      Which city is this for?

      • Dipak says:

        Hi Abhishek, am in vadodara city, Gujarat

        Thanks, dipak

        • Abhishek Jain says:

          Hello Mr Vyas,

          You would need about 2.5 tons of cooling in peak summer. If you put two one ton inverter ACs, then it would meet the requirement and would save you electricity as well. Although cold air remains at the bottom and would not go up the stairs, but still it is better to have good insulation so that heat exchange does not happen between air above and below.

          Also with two one ton ACs you can selectively on both or only one when needed. This can further help you cut your electricity bills. Using only one will result in local cooling (area near the AC), but it will not consume as much electricity as a two ton would. You can look at these ACs:

          Daikin FTKM35PRV16 or FTKP35PRV16 (1 ton)
          Hitachi ACE or iClean Inverter AC (1 ton)
          Sharp AH-XP13LV, AH-XP13PHT, AH-XP13PMT, AH-X13PET (1.1 ton)
          Samsung AR12HV5NBWK or AR12HV5DAWK (1 ton)
          Panasonic CS-S12PKYP Econavi (1 ton)

    I would like to buy AC for my bed room in Ahmadabad, which is at 3rd floor in flat there is two more flat over it facing sunlight from 02 PM to 07 PM during summer. bed room size is 11*10*10, Which one is best window or split? along with brand(How brand is effected with same EER).
    Pl. Suggest me AC with brand and model no. for daily usage is 8 Hrs. in summer and Monsoon. it must be high energy efficient.

    • Abhishek Jain says:

      Hi,

      I would suggest that you go for 1 ton inverter AC for your room. You can look at these models:

      Daikin FTKM35PRV16 or FTKP35PRV16 (1 ton)
      Hitachi ACE or iClean Inverter AC (1 ton)
      Sharp AH-XP13LV, AH-XP13PHT, AH-XP13PMT, AH-X13PET (1.1 ton)
      Samsung AR12HV5NBWK or AR12HV5DAWK (1 ton)
      Panasonic CS-S12PKYP Econavi (1 ton)

      • Dharmesh says:

        Thanks Abhishek for prompt response,
        What is the diff. in terms of energy saving as well as maintenance between 5 star and inverter AC?
        From above list which is most energy efficient and least maintenance required AC?

        • Abhishek Jain says:

          Hello Mr Dharmesh,

          Inverter compressor is 20-30% more energy efficient than a fixed speed compressor of the same energy efficiency ratio (or EER). Any AC with EER of 3.5 or more is rated as 5 star by BEE. The highest EER models available in India are by Hitachi at around 3.8 EER. As for inverter tech, (amongst the list mentioned above) Hitachi ACE inverter 1 ton has EER of 4. Daikin FTKM35PRV16 has EER of 3.8.

          Inverter ACs have PCB which needs to be protected from power surges and large voltage fluctuations. The repair cost of PCB is high (I heard about 15K or so). So it is important to protect that. Japanese models are durable and these models also have anti corrosion coating on the condenser.

        • Abhishek Jain says:

          Hi Ujwal,

          A 11×9 room in mumbai needs 0.75 tons of cooling. The best you can buy is 0.75 ton inverter AC. You can look at any of these:

          Daikin FTKM25PRV16
          Sharp AH-XP10LV
          Mitsubishi MSY-GE10VA
          OGeneral ASGA09JGCA

          The Sharp model will be most economical and will easily fit in your budget. I think that will be the best choice for you.

  21. sandeep says:

    sir,
    with regards plz suggest ac for my room home office first floor on two storey house in patiala punjab. room size 15*11*10. with 11 ft wall expose to morning sun. with 5*5 window on this wall. room having pc & laptop. ac usage for four hours in evening 4 to 8 during summer may to sep. whether split or window ac and have low running cost.

    • Abhishek Jain says:

      Hello Mr Sandeep,

      From 1st floor room in two storey house I guess it has a ceiling directly exposed to sun. In that case you need about 1.9 tons of cooling in peak summer. Your usage is not high so going for a BEE 3 star rated AC will be ok. You can go for BEE 3 star rated 2 ton AC for your room. You can look at these models:

      Hitachi (RAU424ETD, RAU324EUDA, RAU324HUD)
      Daikin FTC60PRV16
      Carrier Kurve 2 ton AC
      Samsung AR24HC3TFUR
      Voltas 243 CYa
      Bluestar 3HW24FA

      It is better to go for split AC as you get more electricity saving models.

    Dear mr abhishek
    You are doing terrific work ! We live in Chennai on the 6th floor with direct sunlight in the bedroom which is 15 by 12. We currently have a York AC that needs to be replaced. As tariffs are high, we are looking at an invertor 2 ton ac. The dealer is pushing mitshubishi, but from a reading of your blog, do you suggest Diakin or Mitshubishi or something else?
    Looking forward to your urgent reply…

    • Abhishek Jain says:

      Hi,

      Your room needs 2 tons of cooling, so you may even go for 1.8 ton inverter AC. Below are the ACs that you can look at:

      1.8 ton inverter AC:
      Daikin FTKM60PRV16
      Daikin FTKP60PRV16

      Or 2 ton inverter AC: Mitsubishi Electric MSY-GE24VA

    • Jothi Ramalingam says:

      Mr Abishek,

      Our AC supplier recommends a 5 star Mitsubishi 2 ton split Ac. He says there are several complaints he has faced with regards the circuit board of the Daiken invertor Ac and the replacement cost after the warranty period is around INR12000. Please can you comment on this.

      • Abhishek Jain says:

        PCBs in inverter ACs are just like any other electronic component like TV. They are prone to failure because of voltage surges and fluctuations. You need surge and voltage protection for inverter AC. The PCBs are expensive.

    Dear Abhishek,

    I am from Faridabad. I want to purchase a 1.5 T split AC for my room of size of 12*12*10. Can you suggest best AC with in my budget of 30000 to 35000. I zero down voltas 5 star executive AC. is it worth or not.

    Regards,

    Sanjay

    • Abhishek Jain says:

      You need 1.3 tons of cooling if the room has more rooms on top of it and there is no direct sunlight on any of the walls. Else if that is not the case then you need 1.7 tons of cooling for the room. If there is no direct sunlight then even 1.2 ton AC should work. If there is sunlight then 1.5 ton AC may fall a bit short during peak summer day time. But on all other days it should work fine. Voltas BEE 5 star 1.5 ton is the best 1.5 ton AC you can buy in that budget. If there is no direct sunlight then you may also think of Sharp or Samsung inverter tech AC of 1.1 ton which can fit in that budget.

  27. Joydip Ghoshal says:

    Hi Abhishek,
    I came across your website while looking for an AC for my hall. Let me first thank you for maintaing such an informative thread and helping out people.

    Now coming to my requirement, my hall is 270 Sq ft and it does get direct sunlight in the early morning. There are floors above my flat, so I am not the one directly below roof. I am thinking I should go for a 2T AC, is that correct? If yes, please suggest some good models/brand. Also do you think 3 Star will be fine or I should look for more energy efficient ones.

    • Abhishek Jain says:

      Hello Mr Ghoshal,

      Which city is this for? The choice of BEE 3 star and 5 star will depend on your usage of AC. We typically recommend people to go for BEE 3 star split AC if usage is less than 1000 hrs per year and price of electricity less than Rs 5 a unit. If usage is between 1000-1500 hrs per year, then we suggest going for BEE 5 star split and beyond that Inverter Tech split AC. This is for 3 years payback for the extra money you pay to buy the appliance.

  28. sudhakar says:

    Hello abhishek,

    I am from Channei.

    My room size is 10X11X10 . I am planning to buy new split AC.

    Side wall will be in sun light 12PM to 6 PM , during this time and night 3 hours will use AC.

    Being in rented house i do not want to buy 1 ton AC which will fit for this so i though of buying 1.5 voltas CYA 5 star AC. ( Later i can take this to new rented house )

    Is there any difference in 1 ton and 1.5 for this room?

    I thought big AC will cool down the place in few mini and save electricity, is that TRUE ?

    One more doubt , can i place the outlet in sunlight ( No place so need to fit in roof) , Will it effect cooling capacity and/or increase power consumption?

    This is going to be my first AC, so please suggest best brand, tonnage and less power. Thanks ;)

    • Abhishek Jain says:

      Oversizing will not help. In fact it will be uncomfortable and will increase electricity consumption. As per my calculation you need 1.2 ton fixed speed AC or 1 ton inverter tech AC. If you have doubts and want to move to a new place, I would recommend going for inverter tech AC of 1.5 ton. Inverter tech ACs are flexible ACs that adjust to the tonnage need of the room. They also have variable power consumption and thus if they run at lower tonnage, they consume much less electricity. I would suggest that you go for 1.5 ton inverter tech AC from Sharp or Samsung. They may not cost too high and will still work well for you.

      • sudhakar says:

        Thank you for the valuable suggestion. And i have two options in samsung –
        Digital Inverter AC AR18HV5NFWK 1.5 TR or Digital Inverter AC (crystal gloss panel) AR18HV5DAWK 1.5 TR. Which is best ?

        • Abhishek Jain says:

          Samsung AR18HV5DAWK has really high EER. If you think it fits in your budget then it is the best choice.

    • Abhishek Jain says:

      Hello Raj,

      You need 1.2 tons of cooling for your room. If you go inverter tech a 1 ton inverter tech AC would be good. Getting a good 1.2 ton split AC model in 30 K is difficult, I would rather suggest that you go for window AC. You can look at these models:

      Whirlpool Magicool Platinum V 1.2 ton window AC
      Hitachi RAV513HUD or RAT513HTD

    • Abhishek Jain says:

      It should consume 0.75 units in an hour assuming compressor is on for 80% of the time. Compressor on time depends on outdoor and indoor temperature. R290 is highly energy efficient refrigerant and that is why the AC consumes less electricity.

    Hi…I need a ac for a 12X10 room which happens to be on the top floor with an open terrace. The room’s ceiling and one wall is exposed to sun all day. This also has an adjacent room used which is used as the drawing room. Wanted something which can have effect in this room too so that it does not need additional cooling since hardly any time is really spent here. What are your suggestions on the best ac. do also advice if window is best or a split for this condition. Have heard O General has great cooling compared to other brands. Is it worth investing in it?

    Hi Abhishek
    how is the performance of CROMA Air conditioners…

  36. Priyanshu says:

    HI Abhishek

    I live in faridabad, room size is 20x9x9 on second floor (nothing above on my floor), 3 walls of my room have other rooms attached with it..and one wall which has one window faces sunlight. Duration of use would be 4-5 hrs during day time and 5-6 hrs in night for 4-5 months in a year.

    And another room (size 12×9) is at 1st floor, only one wall faces sun, usage would be 2-3 hrs a day, for 3-4 months in a year..

    It would be good if you can let me know the tonnage, brand and model of the most energy efficient ac with COPPER which would suit me most… Pls suggest both spilit and window

    • Abhishek Jain says:

      Hi Priyanshu,

      For the 20x9x9 room you need 1.7 to 1.8 tons of cooling. A 1.5 ton inverter AC would be good for you (also considering your usage of AC). You can look at these models:

      Hitachi Ace or Kampa inverter 1.5 ton
      Daikin FTKM50PRV16
      Samsung AR18HV5DAWK
      LG BS-Q186C8R6
      Sharp AH-XP18PHT, AH-XP18PMT, AH-X18PET, AH-XP18MV
      Samsung AR18HV5NFWK

      For the 12×9 room 1 ton AC would be fine. Usage is less so a BEE 3 star rated AC would also work. You can look at these ACs:

      Hitachi RAU412HTD or RAU412KTDP or RAU412KTDC (EER of 3.29)
      Samsung AR12HC3USUQ or AR12HC3TFUR or AR12HC3ESLW (EER of 3.29)
      or even Onida S123TRDN, S123FLT-N, S123SMH if you are looking for cheaper ACs.

      If you want 100% copper then you can look at Carrier Superia Plus 1.5 ton inverter AC for bigger room and Carrier Kurve 1 ton AC for the smaller room.

    • Abhishek Jain says:

      You need 1.2 ton cooling for your office. If you go inverter tech, you need 1 ton inverter AC for your room. You can look at these models:

      1.2 ton AC:
      Hitachi RAU514IUD or RAU514EUDA
      Whirlpool 3D Cool Platinum V or Magicool Platinum V

        thanks a lot Abhishek

        one more thing ….if i go for IFB 1.5 Ton Split AC – IACS18KA3TC ……………..then is it a good opition…………what u say dear

        • Abhishek Jain says:

          Not really. Here are the reasons: 1) 1.5 ton AC would be highly over sized for your room and will consume more electricity. 2) On top of it is is a BEE 3 star rated AC, so with over sizing it will be as good as BEE 2 star or 1 star AC. If you are looking for fixed speed AC, then you should not go for more than 1.2 ton AC if you want to save on electricity. Your usage is also high.

    • Abhishek Jain says:

      1 ton would be sufficient for the 1st room, but for the 2nd room you would have to go for 1.5 ton AC. You can look at Carrier Superia or Kurve models if you want 100% copper.

    Duration of use would be 9 hrs a day for 25 weeks in a year.
    It would be good if you can let me know the tonnage, brand and model of the most energy efficient ac which would suit me most.i also confused in rotary and reci compressor

    Hi abhishek, your blog is the most helpful one that I saw on internet. Many congratulations and thank you. I am trying to decide which brand of window ac to buy. Last time I bought a whirlpool copper coil ac and it didnt really work too well. I need to chose an ac that will help me cool an area of 20 by 15 . And I live in noida where acs require most servicing. :) looking for enerygy efficient window ac that is , say hassle free. And whether you would rate godrej acs good. Last q, if you recommend going for split ac this time rather than window. Thanks

    • Abhishek Jain says:

      Hi Ruchi,

      20×15 room in Noida would need about 3 to 3.5 tons of cooling depending upon how hot your room gets. If it is has walls/ceiling exposed to direct sun (from west/south west and top), then it would need more, if it is not exposed to sun or only to morning sun and there is less sunlight in the room in general, it would need about 3 tons of cooling. I would rather recommend you to go for split ACs because the energy efficiency of split AC is one level higher as compared to window ACs. So a BEE 5 star widow AC consumes the same electricity as BEE 4 star rated split AC. However the choice will depend on your usage of AC. How many hours/day and months/year do you use AC? By the way Godrej ACs are good ACs. Some of them have really high energy efficiency. If you go for cooling the whole room, then you would need 3 tons of cooling. However if you are fine with local cooling (just in the area near the AC), you can go for smaller tonnage. A 1.5 ton AC would consume less electricity however it will just cool a small area right in front of the AC. So if it is your bedroom, then you would have to keep the AC right in front of you beds. Let me know your usage and you choice of window/split and I can recommend you some models. And also let me know if you need local cooling or you want to cool the whole room.

    Hi, i m from faridabad, my room size is 23×9, 2nd floor(nothing above it) , one wall faces sun, pls suggest for 1.5 ton or 2 ton ac

    • Abhishek Jain says:

      It’s more than 2 ton as per my calculation. However 2 ton should work on most days, but may fall short a bit during peak summer days.

    • Abhishek Jain says:

      You should go for 2 ton AC.

    • Priyanshu says:

      Sorry sir,
      Room size is actually 20×9…dealer told me 1.5 ton will be sufficient with non-inverter technology.. He also told me that O-general AC of 1.5 ton(window) with 2 star rating will be better option
      i m confused
      pls suggest

      • Abhishek Jain says:

        1.5 ton fixed speed AC would have worked if your room did not get direct sunlight on the ceiling and wall. But the requirement would be more as your roof/walls get heated. So a 1.5 ton AC may fall short during peak summer day time. Also 2 star rated window AC is equivalent to 1 star rated split AC. We do not recommend people to go for anything less than BEE 3 star rated split AC unless the usage is very less (occasional usage). A 2 star rated 1.5 ton window AC would consume about 1.5 or 1.6 units in an hour whereas a BEE 5 star rated one will consume 1.1-1.2 and inverter tech may be 0.9-1 unit in an hour. So if your usage is 10-11 hours, the 2 star window AC would consume 16-17 units in a day, whereas inverter would consume 10 units. If your electricity rates are about Rs 6-7, then for 10 units you would be paying Rs 60-70 per day but for 2 star AC you would be paying about Rs 110-120. If you save Rs 50 per day, it means saving of Rs 1500 per month. In 4-5 months you can save about Rs 6000 in a year of use. So you need to decide if you want low initial cost or low electricity cost.

    Ya sir one wall receives direct sunlight for few hours in morning time. I hail from Lucknow

    • Abhishek Jain says:

      You need 2 ton AC for your room. You can look at these models:

      Hitachi RAU524IUD or RAU524HUD or RAU524ITD
      Mitsubishi Electric MS-GK24VA
      Voltas 245 DY
      Bluestar 5HW24MA

    • Abhishek Jain says:

      You need 1.5 ton window AC for your room. You can check:

      Hitachi RAV518HUD
      Hitachi RAT518HUD
      LG LWA5CP5F1
      Hitachi RAW518KUD
      Panasonic CW-KC1814YA
      or any Voltas BEE 5 star rated window AC.

      There is no drawback of R22 other than it is not environment friendly. The gas will be available in market for next 15-20 years.

      • harpal says:

        Namaste sir,many thanks for your prompt reply,regards

      • harpal says:

        namaste sir,thanks for your prompt reply , are there any eco friendly window ac available in india, please guide me naming the brands etc, thanks

        • Abhishek Jain says:

          Hello Mr Harpal,

          None of the window ACs have R410A. If you want eco friendly R410A gas ACs, then you will have to go for split ACs.

    Hi Abhishek,

    I live in Ghaziabad (U.P) and i am planning to buy split ac. I live in first floor and bed room is of 11ft *10ft*9ft and direct sunlight dont hit the bedroom.

    We planned to go for Hitachi but we have heard that hitachi is havinng problems now-a-days ( from hitachi’s one of customer care member). After that we planned for Voltas but i went through its reviews and they are not really good.

    Now we are totally confused about the brand. We need 1.5 ton Split AC with 100% copper. Please suggest the appropriate brand with model number for Split AC.

    Thanks!
    Versha

    • Abhishek Jain says:

      Hi,

      If yo do not get direct sunlight in the room or on walls/ceiling. 1 ton AC would be good enough for you. 1.5 ton would be oversizing and waste of electricity. You can go for Carrier 1 ton Superia model, it will be 100% copper.

      • Versha says:

        Hi Abhishek,

        Thanks for reply! The room is not getting direct sunlight but direct sunlight falls on attached varandah due to which in daytime room gets hot and also we have one 10ft*9ft*9ft room attached to the bedroom (without any door), thats why planned to go for 1.5 ton. Also we have number of furnitures in the room.

        Some of my friends told me to go for Daikin also. Is Daikin brand for Split AC okay.? I also want to know the performance of Carrier or Daikin Split ACs. Nd what about their EER. Also, do these Acs have r22 refrigerant.?

        • Abhishek Jain says:

          If you have another room attached without any door then you need about 2 tons of cooling (if you suspect that room gets too hot). In that case you can potentially go for 1.8 ton inverter AC as well. Daikin as a brand has much more energy efficient models than Carrier. However they do not have 100% copper models (which you wanted). They have anti corrosion treatment on the condenser. Most lower efficiency models (BEE 3 star and less) have R22 and higher efficiency models (BEE 5 star and inverter tech) have R410A or R32 (in case of Daikin). Daikin has some of the most efficient models in Split ACs (especially inverter tech).

    Hi Abhishek,

    Warm Greetings!

    I live in Chennai just one kilometres far from the sea shore and I’m planning to buy my first A/C for my home.

    My younger brother has a 1.5 ton Samsung A/C (2 Star) in his 10X12ft bedroom and it did faced lot of problems. After seeing this my worries and concern of purchasing a better A/C for my bedroom has gone up.

    I live in 1st floor and the window is faced towards West side, hence direct sunlight would hit the room say post 2 pm in the afternoon.

    Please suggest me the best brand suited to my location and room size. Also I’m wondering should I go for a 1.5 ton A/C.

    Your suggestions and advice would be highly appreciated.

    Cheers!

    Prabu

    • Abhishek Jain says:

      Hi Prabu,

      As per my calculation a 10×12 room in chennai would need about 1.3 ton cooling during peak summer day time (a 1.2 ton AC would work mostly, however if the room gets too hot in summers, then may be you will have to go for 1.5 ton AC). What sort of problems were faced with the AC? Did it have a lot of gas leakage? Also how much is your usage of AC in hrs/day and months/year?

      • Prabu says:

        Yes, my brother’s AC did had some gas leakage problems and he went ahead changed the cooling unit etc. but really not sure of the exact reason. But looking at some of the tips posted here I was assuming that I may only need a 1 ton AC. Your suggestion for a 1.2 to 1.5 ton AC comes as a little surprising for me atleast from a cost perspective..:-(..anyways will seek your further advice on this.

        • Abhishek Jain says:

          Hello Mr Prabu,

          You can reduce the heat load in your room by applying insulation techniques. Not sure if the roof is exposed to sun, but if it is then you can put white reflective paint on the roof top or can apply thermal insulating material like XPS boards (or extruded polystyrene boards). For the walls, you can apply thermal insulating wall paper or XPS boards. Try putting thick curtains on the windows so that you can put them on when you use AC. You can read more at our insulation section: https://www.bijlibachao.com/save-electricity/insulation ….. if you reduce the heat a bit, a 1 ton AC would be good enough. Also do check your west/south-west walls if they get quite heated up as compared to other walls. If they do not, then you may not need to use all these things and you may still go for 1 ton AC.

    Hi abhishek. ..I want to know review for LG SPLIT AC MODEL NO- LSA5PW5M …WILL IT BE GOOD FOR 10*12 SQ FT…OR IF U HAv better opinon plz suggest

    • Abhishek Jain says:

      Which city is this for? Do you get direct sunlight on any of the walls or on the roof of the room? How many hours/day and months/year will you use the AC?

  49. Himanshu says:
