Electricity Saving Tips For Homes And Offices

Tips to choose the best brand air conditioner

By on January 21, 2014

Air Conditioner 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.

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
    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:

      You need 1 ton fixed speed or 0.75 ton inverter AC, you can look at these:

      Godrej GSC 12 FG 6 WNG or GSC 12 FG 6 BNG
      Mitsubishi MS-GK10VA
      Whirlpool 3D Cool Climate Control
      Panasonic CS-XC12QKY

      Or you can also look at 0.75 ton inverter tech AC models:

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

    best buy Voltas DC Inverter (1.5T 18V DY) or samsung AR18HV5DAWK

  4. sanjay singhal says:

    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.

  5. 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.

  6. 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.

  7. Raj says:

    Hello abhishek,

    I live in ahmedabad which is very hot during peak summers around 42-44 °C.

    My room size is 11*10*10 feet and ceiling is subjected to sunlight during 9 am to 3 pm, There is no floor above it, No wall is subjected to sunlight.

    Average use of 6-7 hrs in a day for 4-5 mounts in a year please suggest me an efficient split air conditioner with tons requierd and which brand should i go for? Budget 30k

    Kindly help me out :-)

    • 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

    is haier split air conditioner is good to buy

  9. satyanarayan says:

    sir, i have bought godrej 1 ton ac GSC 12 FT 5 WNG 5star rating. Power input is943 watts.i would like to know how many units of electricity will it consume for 8 hours use.i live in chennai .The refrigrant used in this model is mentioned as r290.What difference does it make in terms of cooling.efficiency.

    • 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.

  11. DT says:

    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?

  12. jatinder pal singh says:

    Namaste sir,many thanks for your prompt reply,regards

    I WANT TO KNOW ONE MORE THING……………THAT WHICH AC IS COMING WITH 100% COPPER IN 1.2 TONS .

  13. Priyanshu says:

    Hi Abhishek
    how is the performance of CROMA Air conditioners…

  14. 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.

    Hi Abhishek,
    I live in town near to amritsar city(Punjab) and am planning to buy an split ac for my office
    The room dimension is 12x9x9feet. My office is on the ground floor (with undercelling) and have no floor on it.
    The roof is exposed to sun directly for whole day and there is one glass door(size-7×8) facing east The room has a provision for split ac and I would prefer to buy one.
    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

    • 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
      Voltas 155 CY

      1 ton inverter AC:
      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)

      • jatinder pal singh says:

        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.

  16. Naman says:

    Hi Abhishek,
    I need split AC for two rooms one is 10x11x9ft another is 11x12x9ft. The first one has no walls exposed to sunlight, only ceiling is exposed to sunlight. The second one has one wall to the west is exposed to sunlight. City is Hardwar and requiredment is 7-8hrs a day. pl. suggest some Ac with copper tube in 40K.

    • 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.

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

  19. ruchi says:

    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
    RUCHI

    • 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.

  20. vikas says:

    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:

    • 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,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).

    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

      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: http://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?

  27. Himanshu says:

    Hello ,

    My room size is 12×12 Sq ft. & on the west size it has glass windows & door. what tonnage I should use. i am thinking to use Hitachi one. Does Hitachi has inverter tecnology AC?

  28. Krishna says:

    Hey Abhishek,
    You are really doing a great job n I am sure you will really help me out with this issue.
    I am from Delhi.I am thinking to buy another ac for my room and not sure which one should I go for.
    I have a Panasonic cube ac (eer 2.79) but I am not quite satisfied with its performance as it shuts itself off or at times starts throwing hot air ( I normally keep the ac at fan speed 1 and temp at 20-24 degree). I have a rented accommodation and transferable job. I live in a 2 story building on 1 st floor (160 Sq ft) so the roof gets really hot.
    I am thinking to sell my old ac and buy a new one, my budget is 30k-35k.
    I would be using the ac normally during the day and hardly at night.
    So please suggest the best split or window ac under my budget.

    • Abhishek Jain says:

      Hi Krishna,

      If there is lot of heat outside and your AC faces the sun directly, then the compressor does not work and you will get hot air. Also as per my calculation you need 2 tons of cooling for your room. In 30-35K you can only get window AC. Also most 2 ton window AC available in market are low on efficiency (BEE 2 star or less). You might have to increase your budget to get decent BEE 3 star rated split AC of 2 ton.

  29. Trinadh says:

    Hi Abhishek, I had been through ur valuable suggestions which are more informative, Now my request is that, you pls suggest me to buy a AC, I am living in Vizag (AP) (just a week back i came from Mumbai) and most of the time I stay in rented house with my family and also a transferable job, My bedroom size is 10X12, at first floor out of 5, nil sun light appears directly, windows are facilitated for WINDOW AC) Now i request (i) Should I go for split or Window ( bcos i am on transferable job and may be i stay for 3-4 yrs at one place) (II) 1 t or 1.5 t (iii) interesting on Voltas should I or any other brand (iv) Star rate 3 r 5 , Request suggest , Thanking you very much in advance and also for ur advises to all needy…Trinadh

    • Abhishek Jain says:

      You need 1 ton AC for your room. A window AC is much easier to shift than split AC (unless the builder has made specific arrangements in the building to put split ACs). Now there are few positive points for split ACs as well: 1) As you keep shifting regularly, your room size will keep changing and thus your cooling requirements as well. An inverter technology AC can handle variable cooling requirements as it has variable tonnage. And inverter tech is available only in split ACs. 2) More and more manufacturers are moving towards split ACs and you have much lesser window AC models available in market. Also the energy efficiency levels of window ACs is one level lower (so a BEE 5 star rated window AC is similar in electricity consumption to a BEE 4 star rated split 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. You can decide accordingly.

      Now for 1 ton window AC, there are very few brands that have a BEE 5 star rated model (and most of them just have one or 2 models). And they are: Hitachi, LG, Voltas, Whirlpool (LG has two models and others have one). If you plan to go for window AC, then these are the only options available in BEE 5 star.

    Hello Abhishek,

    Ur articles r very informative and let me thank u for ur efforts !

    I am planning to buy an Inverter AC of 1 Ton capacity but i am confused about which brand to opt for ! I have zeroed in on Dikin, Hitachi, Bluestar, Voltas and Sharp ! I hv heard that sharp uses Mitsubishi Compressors and r as good as Dikin !
    Whats ur take on d brands mentioned above ! I need an AC which is durable and cools well ! Pls suggest d most reliable brand out of above. I live in Aurangabad (MH).

    Thanks,
    Arjun

    • Abhishek Jain says:

      From an energy efficiency perspective I have seen Hitachi, Daikin and Sharp offer the most efficient ACs. I have got mixed reviews about post sale service of Hitachi and Sharp. Not heard that many negative things about Daikin though. Price wise Sharp will be cheapest, and Hitachi most expensive.

      • Arjun Lahoti says:

        Thanks for ur Reply Abhishek !

        I have now decided to go for Daikin Inverter AC ! The dealer of Daikin is also the official Dealer of Mitsubishi Electric Co. I have heard that they also make some very good ACs ! I am confused about Mitsubishi Electric Co. and Mitsubishi Heavy Industry Co. I Think the MHI make quality product thn MEC but i coudnt find MHI dealer anywhere in India. Whats ur Opinion about MEC and MHI and which one to opt for out of Daikin and MEC as MHI is not available in India.

        Thanks !

        • Abhishek Jain says:

          Daikin has more energy efficient models than MHI or MEC. Most japanese brands are good on technology/reliability and so I would say Daikin also makes great products.

  31. Vishal K. says:

    Hi Abhishek,

    You are doing a great job. Keep it up and God bless you.

    I am from Mumbai and have a ground floor flat. I am planning to buy my 1st Air Conditioner and I am really confused. I am planning to buy 2 air conditioners for following rooms
    1. Living Room – 180 sqft (does not get any direct sunlight) (usage would be around 2-4 hours during day time)
    2. Bedroom – 160 sqft (Again not much of direct sunlight) (usage would be around 8 hours during night time)

    This weekend I went to AC dealer to check out AC options. The dealer mentioned that I should not opt for inverter technology as it is a new technology and they are getting too many complaints for inverter ACs. I feel that’s a typical salesman BS. Also they mentioned that I would need 1.5 ton A.C. for both rooms which I find odd as I was thinking that 1 ton inverter AC/each room should suffice.

    1. Can you please recommend tonnage for both rooms also any specific AC models (I was planning to go for Sharp ACs)?

    2. Is it okay to go for 3 star ACs if usage is going to be low?

    Thanking you in advance.

    Best Regards.

    • Abhishek Jain says:

      Hello Vishal,

      You need:

      for 180 sq ft room: 1.3 ton fixed speed (or 1.1 ton inverter AC)
      for 160 sq ft room: 1.1 ton fixed speed (or 0.8 ton inverter AC)

      Now for the Living room, if you do not go for inverter tech AC, then you may have to go for 1.5 ton AC. Ideally I would suggest BEE 3 star AC, however if you get a 1.1 ton Sharp Inverter AC for around 35K (which is what a BEE 3 star 1.5 ton AC may cost), then it might not be a bad idea to go for inverter AC.

      For Bedroom 0.8 ton inverter AC from Sharp would be good. Now as per what I have heard, Sharp’s service may be patchy at some places, but I have got some good feedback for the brand from people in Mumbai. The other good option can be going for Daikin’s 1 ton inverter AC models.

      For low usage 3 star AC is fine, but if you can get smaller sized efficient ones at the same cost that can justify your needs, then it is better to go for them. I just hope that you do not have any walls facing sun from west, else the tonnage requirement may increase.

    • Vishal K. says:

      Many thanks for your prompt response. Highly appreciated. Not sure why can’t I see it here though.

      For my bedroom, I do have west side facing wall but it doesn’t get too much of direct sunlight as my flat is surrounded by trees and buildings. But to be on safer side, I’ll go for 1 ton Inverter AC instead of 0.8 ton.

      I have zeroed in on Sharp AH-XP13PMT model as I have read lots of good comments on Sharp machines. Hoping for trouble free experience.

      Thanks again for your reply.

  32. Sourav sarkar says:

    hello Abhishek

    Very nice blog indeed.

    I live in Kolkata which is hot & humid. My room is 14x10x10 & I live on the 2nd floor (there r 2 floors above me). I also plan to use ac for about 4 hrs a day on an average. I am planning to buy an ac in this coming week.

    what tonnage ac should I go for ?
    I have shortlisted Carrier based on feedback from other users. Is it good?
    Also is there 1.3 ton ac available in market or does it have to be 1 ton or 1.5 ton?

    Waiting for your reply.

    Thanks again.

    • Abhishek Jain says:

      Hi Sourav,

      You need 1.2 ton AC for your room. There are 1.2 ton ACs available in market. Whirlpool and Hitachi have some models. Whirlpool has some good models. Your usage is less, so even BEE 3 star ACs would be good. However most 1.2 ton ACs are higher efficiency ones (BEE 5 star rated). If you go for Carrier, then you will have to go for 1.5 ton. In that case you can also look a Carrier’s 1 ton Kurve inverter AC (which might cost you the same as 1.5 ton AC) and would work just as well. Carrier has 100% copper models that are good. And it certainly is one of the good brands.

  33. Lakshman says:

    Hi Abhishek,

    Your comments are indeed very good and informative. I need your help in choosing a split air conditioner. I live in Mumbai.

    My living room size is 200 sqft approx and is facing West. We live on the second floor. Which Brand and tonnage would you suggest me to go for.

    My bedroom size is 120 sqft and is facing South West and it has a tree cover. Which Brand and tonnage would you suggest me to go for.

    • Abhishek Jain says:

      You need 1.7 ton (or 1.5 ton inverter AC) for 200 sq ft room and 1 ton (or 0.75 ton inverter AC) for 120 sq ft room. What is your usage of AC in hrs/day and months/year?

      • Lakshman says:

        Hi Abhishek,

        I do not have any AC right now. But then the summers are terribly hot, so the need. I went to the shop they showed me a Hitachi Inverter AC of 1 ton of 2013 make and it costs around Rs. 40k. Is it ok to buy a 2013 model.

        please advise

        Lakshman

        • Abhishek Jain says:

          It is better to buy 2014 models. You will get better Daikin or Sharp 1 ton inverter AC models in that price range.

  34. Bhavin Kamani says:

    Hi Abhishek,

    Thank you very much for your articles. I need your help in choosing an air conditioner for my father in Kolkata.

    My constraints are

    - Can install only Window AC
    - Room size is about 170 sq. ft
    - He is currently using an old 1.5 ton AC which we are planning to retire
    - Usage is almost 10-12 hrs a day about 10 months in a year.

    With your experience, can you suggest me a reliable Air Conditioner Brand and Model which is also energy efficient? Going by your articles, inverter technology seems to be a good option. Are Window AC using this technology available in India?

    Thanks a ton in advance
    Bhavin

    • Abhishek Jain says:

      Hi Bhavin,

      1.5 ton is fine for the room if there is no direct sunlight on walls/ceiling. And yes there are no inverter ACs in window. So the best you can do is to go for the most efficient window ACs. You can look at these models:

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

    Hi Abhi,

    Hi Abhi,

    Please will you guide me for 5stare split AC with all functions… which brand i should go for my house.. house is around 260ares… northeast side widow …. pls pls pls suggest me

    • Abhishek Jain says:

      Hi Gitu,

      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 do you live in, size of your room, which floor is it 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.

      Hope this helps.

      Regards,
      Abhishek

  38. prashant says:

    hello sir,

    i live at ground floor in Delhi. my bedroom is of size 10x10x12 ft approx. Sunlight never reaches to this room. the AC would exhale its hot air to an internal shaft.
    I am in a transferable job so preferring a window ac.

    Please suggest a good electricty efficient ac.

  40. sammy says:

    Hi
    Had a doubt in mind.My outdoor unit of split ac is placed on the roof top.So I wanted to ask if exposure to sunlight or rain will affect the functioning of the ac in anyway?

    • Abhishek Jain says:

      exposure to sunlight is not good for efficient working of AC. So you should avoid it.

      Regards,
      Abhishek

  41. Ashwin Lewis says:

    Which AC can I select. Voltas Magna 185MY or Hitachi RAU518EUDA Follow me. These are the 2 I narrowed down after a lot of research. Waiting for your advice.

    • Abhishek Jain says:

      Oh that one is easy “Hitachi RAU518EUDA Follow me”. EER of this model is 3.8 where as Voltas Magna 185MY is 3.31. Voltas model is a window AC while Hitachi is split.

  42. Shalini says:

    After much deliberation,keeping the after sales service and prior experience with the brand in mind,got a 1.5 T LG Inverter V AC.Thank you Abhishek for helping to decide on the brand.
    It cost Rs 47,500 excluding the installation charge.

  43. Ashish Kumar says:

    Hi Abhishek,
    Let me first congratulate you for such a nice website and so many useful tips.

    I live in Gurgaon which is very hot and dry and bit humid after onset of Monsoon. I am looking out to buy a window ac as live in a rented accommodation and might have to change places after 2/3 yrs. My current room size is 12*14*14 feet and have annual consumption in 1500-1800 hrs.

    Please suggest one model/brand. How does post sales service help in case of an air conditioner? Ideally, one should not need it. What does the normal servicing an air conditioner involve and one should be careful about.
    Thanks.

    • Abhishek Jain says:

      Hi Ashish,

      You need 2 tons of cooling for your room. There are hardly any energy efficient window ACs in 2 ton capacity. And your usage is quite high. Would suggest you to reconsider going for split/inverter AC.

      Regards,
      Abhishek

  44. M. Afzal says:

    My room is 13’8″ by 10′, on the second floor in a four storied complex in Kolkata. The room is west facing with approximately 24 sq ft of window covered with glass on the western wall.Would a window ac serve my purpose or should I go for an inverter ac and of which capacity. Which brand would you suggest based on efficiency and power consumption.

    • Abhishek Jain says:

      Hello Mr Afzal,

      Your room needs 1.2-1.3 tons of cooling. If you go inverter tech you would need 1-1.1 ton inverter tech AC. Both window AC and inverter AC can serve your purpose and the choice between the two does not depend on the size of your room. If you go for window AC then you will have to go for fixed speed 1.2 ton AC. If you go inverter tech (which is a split AC) you can go for 1 ton as well. And obviously Inverter Tech will be highly electricity efficient and will save a lot of electricity. But the cost benefit will depend on how many hours do you use the AC for in a year.

      Hope this helps.

      Regards,
      Abhishek

  45. Ankush H Jain says:

    Hi, Abhishek

    First of all a big Thanks to you for all your pages of Air Conditioners. Each one was filled with lot of information and the best part, they were all in layman’s terms.

    After reading almost all your pages on Air Conditioners I was able to come down to few parameters need for buying AC for my bed room, but still few points are unclear to me hope you solve it out.

    Basic Info :
    Room size : 11 *12 Ft
    Room has window facing EAST (sunlight in the room till 12:00 PM),
    A loft of 3ft height
    I am from Chennai.
    I am gonna use it for 8 hours a day, mostly in night and afternoon.

    So i noted down few points from your posts :

    1. I need a 1.5 T fixed type AC or 1.2 T Inverter AC.

    Also with my usage condition a 3 star AC is efficient since break even for initial cost will take 7 years approx.

    Query :
    1. Is 1.2 T inverter AC can be efficient as 1.4 T ?
    2. All this stats as quantitative but if you have by qualitative which brand you suggest.
    – In your posts you mentioned LG, Onida, Godrej to be good in EER Ratings thats why better rankings but are
    there internal parts really durable ?
    – Mitsubishi, Toshiba, Daikin, Bluestar which would be more durable ?

    • Abhishek Jain says:

      Hi Ankush,

      1) A BEE 3 star 1.5 ton AC would consume about 1.3 units in an hour, whereas 1.25T inverter AC would on an average consume about 0.9 unit in an hour. So for 8 hours usage you would save about 3 units a day.

      2) Japanese brand (Hitachi, Daikin, General, Sharp, Panasonic, Mitsubishi) + Carrier + Bluestar are in general better in terms of reliability. But you also need to factor in the post sales service by these. Would recommend you to talk to people around to confirm about the same.

      Hope this helps.

    Hi Abhishek,

    I am Ratnadip,living in Kolkata.I am planning to buy 1 Inverter A/C.
    temp of Kolkata is now 40-42C.
    I am staying in 4th floor(Top Floor)

    The room is 11*10*10 (L*W*H). it has a 2 medium window pointing to east side & 2 medium window pointing to north side .Ample sunlight comes to during day time and exposed with direct sunlight of 1 wall. there is no false roofing. i stay in first floor and there is another floor (2nd floor) in the same building which has houses. There are little number of trees near by and room .will be using the AC mostly during night & noon time in weekends.

    I am preferring Hitachi/Daikin/Carrier brands.

    Which one will be more energy efficient,most durable,working properly in long run.

    (I Heard Hithachi service is not good in kolkata. )

    Can you please suggest which brand along with usage (1T or 1.2T or 1.5T) i should buy.

    My budget is 40 — 55 K.

    Regards,
    Ratnadip

    • Abhishek Jain says:

      Hi Ratnadip,

      You just need a 1 ton inverter AC for your room. If you do not prefer Hitachi then you can go for Daikin, as it is quite energy efficient. You can easily get 1 ton Daikin inverter AC in about Rs 35K.

      Hope this helps.

      • Abhishek Jain says:

        You need 1.5 ton AC for your room (1.4 ton cooling for the 1st room and 1.3 ton for the 2nd). Carrier has 100% copper models so I would suggest you to go for that as it will provide more durability.

  47. Sharat says:

    Hi
    I want to buy a 1.5 T split AC within 50k.I am thinking of buying one with inverter technology.Which one would u suggest between LG,Panasonic Daikin and voltas?

    • Abhishek Jain says:

      It depends on what you want. LG and Voltas have good service network. Daikin and Panasonic are good on technology/reliability. Balancing both is important. Along with that you also need to compare the energy efficiency ratios of various models. Some models of LG and Daikin have quite high EERs (of about 3.82).

      Hope this helps.

    Hi Abishek,

    Pleasantly surprised to come across your blog today and was impressed by your detailed replies to most of the user queries.

    I stay in chennai and am planning to buy an AC (split/inverter) this week and need your guidance regarding it

    The room is 12*12*10 (L*W*H). it has a big window and ample sunlight during day time and not exposed too much of direct sunlight because of adjacent building. there is no false roofing. i stay in first floor and there is another floor (2nd floor) in the same building which has houses. There are good number of trees near by and room is blessed with good airflow and light. it has a loft which is covered completely. will be using the AC mostly during night.

    Going by your comments so far, i hope a 1 ton should be sufficient. there are indeed acute power fluctuations during the night (especially between 10-12).

    Please suggest me whether i need to go for an inverter AC or a normal Split AC. some people are suggesting to go for double/triple boosters. please guide on those aspects as well. My budget is 25-40K

    Thanks & Regards,
    D.Karthikeyan

    • Abhishek Jain says:

      Hi Karthik,

      You room needs about 1.2 tons of cooling. 1 ton inverter AC would be good for you. You should get one from Sharp/Carrier/Daikin in about 30-37K. The choice between inverter and split will depend on your yearly hours of usage of AC. We suggest people to go for BEE 5 star or Inverter AC when the usage is more than 1000 hrs a year and electricity tariffs are more than Rs 5 per unit.

      Hope this helps.

      Regards,
      Abhishek

      Econavi have sensors that can detect presence of people in room or day/night. But if it is a fixed speed compressor then the only thing that the sensor can do is shut on or off the compressor. Inverter technology has variable speed compressors that can adjust their speed based on the need of the room. Just like you have accelerator in a car which can speed up or speed down the car based on how fast you want to go, inverter tech can speed up or speed down the compressor based on the need of the room.

      Hope this helps.

      Regards,
      Abhishek

      • garima says:

        So the econavi model will work like a normal inverter ac with added benefits like detecting a person.right?

        • Abhishek Jain says:

          If you are talking about a model with inverter and econavi features, then that is right.

    Hi I am Raju. I have to purchase new split inverter a/c for my flat. My flat is on top floor. The area of my flat is 120sq ft. and at south east direction 56 sq ft window, which is covered by sun control film. I have to purchase inverter A/c. Can you please help/ guide me, which brand is cheap and best available in mumbai market

    • Abhishek Jain says:

      Hi Raju,

      A 0.75 ton inverter AC would be good for you as mumbai is more humid than hot. You can look at these models:

      Daikin (FTKM25 or FTKP25 or FTKE25) (snapdeal price of Rs 27000)
      Panasonic CS-YS9PKY (compareindia price of Rs 29300)
      Sharp AH-XP10LV (snapdeal price of Rs 27881).

      Hope this helps.

    Hello,
    I have narrowed down my search to two brands,which one do you think would be a better choice in 1.5T split AC – Voltas or Daikin?

  53. Chandran says:

    Hi Mr.Abishek,i appreciate your efforts..
    I Live in the Hot city of Trichy,Tamilnadu,I am planning to buy a split ac for my house,I live in the first floor (no house above)
    room dimensions as follows…

    12x9x9 (ht)
    12 wall exposed to west sun and has a 18 sqft window
    9 wall exposed to north and has a 18 sqft window
    and we have loft full of things (3 sides of the room)
    and they are not covered,and no false ceiling done.
    we only 3 people sleep there,we require ac for 3-4 hrs/Night only,,,

    online tools estimate my tonnage to 1,but a local ac technician says that my loft is the culprit and it will require 1.5 T

    at present we have a panasonic cube ac (1.25 T) 2 star which isn’t cooling as it used to be 2 Years back,
    (even that wasn’t cool enough like the LG does in my neighbour’s house)
    and it makes lot of noise,and more importantly i suspect it consumes a lot of electricity

    please,suggest me an efficient split ac and the tonnage required within a budget Rs.40000/-

    awaiting your reply
    Chandran

    • Abhishek Jain says:

      Hello Mr Chandran,

      What is the size of the loft? It can certainly be the culprit as when you use Air Conditioner, everything that is kept in the room, and every corner of the room gets cooled. So if you have a loft full of things, the AC will cool them as well. As per regular calculation tonnage for your room comes out to be 1 ton.

      Also did the 1.25 ton AC cool well 2 years back? Did the lofts have similar amount of stuff at that time as it does now?

      Regards,
      Abhishek

      • Chandran says:

        Thanks sir,for your sincere reply,
        Loft remains the same for 3 years sir :(
        Cube ac used to provide a comfortable chill,but it never made us shiver..
        (attached graphic)

        Sir,I really like 1TR Samsung Triangular Inverter AC..AR12HV5NBWK (R410A)..

        but,i will only go with your suggestion

        • Abhishek Jain says:

          Hello Mr Chandran,

          Just wanted to check if you close the door/window when you switch on the AC. Ideally 1 ton AC is more than enough for your room. A 1 ton Samsung inverter AC would be awesome. I can also see a small storage space just below the loft on one side. AC is meant to cool enclosed space and all the things kept in the enclosed space. So lesser the enclosed space, lesser the things in the room, lesser would be the tonnage required and lesser will be electricity consumption.

          Hope this helps.

          Regards,
          Abhishek

          • Chandran says:

            Thanks a lot sir, without your expert advice i would have chosen an over sized ac,

            and you educated me in lot of other aspects like EER, R410A, and clarity on Inverter technology,

            as per your advice i will try to make the room less cluttered :) and cover the lofts,
            i will leave my comments after i installed the “triangle” ac..

            and my next mission would be “Superfans” (again it’s because of your informative blog)

    • Abhishek Jain says:

      Hi Monica,

      The room is quite big, you would need a 1.75 ton inverter AC to cool the room. You can look at Sharp AH-X21RET, Panasonic (CS-S24PKYP or CS-TS24PKYP), or any of the 2 ton inverter AC models.

      Hope this helps.

    Hi Abhishek
    Many thanks for your kind reply
    I would be happy if you would clarify the following doubts
    1) How is performance of LG and voltas 1 ton inverter AC
    2) I heard that inverter AC has more electronic components than conventional AC which are sensitive and are susceptible to damage from fluctuating voltage and also the spares are costly
    3) inverter AC is better only in areas where there is continuous usage all year round where as in place like mysore it will be used in peak summer for 2 months
    4) Does inverter AC use copper coils in indoor and condenser unit
    5) I have also heard in normal AC (other than inverter) more the efficiency or the star rating copper coils in condenser gets replaced by aluminum coil is it true like in voltas 1T after 3 star rating copper coil gets replaced by aluminum coil in condenser. is aluminum coil equally efficient to copper coil
    Clarification of These points would help me in better AC selection.
    Anticipating your reply.

    • Abhishek Jain says:

      Hello Mr Shankar,

      Here are my responses:

      1) Have heard good review of LG inverter AC, but have not heard anything on Voltas yet. If you buy a voltas, do let us know.
      2) All ACs needs a stabilizer if there are voltage fluctuations (both non inverter and inverter). Inverter does have more digital components, but if you have fluctuations, then stabilizer is important.
      3) Not really, load varies even between day and night. Days are hot, nights are colder and Inverter AC can help in the same. Even between months, March is less hot than May. So inverter will save some electricity. However the economic benefit of the savings will depend on your hours of usage and electricity rate. If your usage is only for 2 months, then most likely it will not pay off early.
      4) It depends on manufacturer. Carrier Superia Plus Inverter AC is 100% copper. But many others are not.
      5) Again depends on manufacturer. Many of the Carrier BEE 5 star rated models are 100% copper.

      Hope this helps.

    • Abhishek Jain says:

      Hello Mr Biswas,

      Your room would need about 1.7 tons of cooling on peak summer day time. If you go for inverter AC, then you would need 1.5 ton inverter AC. Sharp AH-XP18PMT (EER 4.41), Sharp AH-XP18PHT (EER 4.41), Daikin FTKM50 (EER 3.8), Hitachi Ace Inverter (EER 3.8), Hitachi iClean Inverter (EER 3.8) have some of the highest EERs in this range. You can choose between anyone of them.

    • Abhishek Jain says:

      Would suggest you to go for Hitachi ACE inverter as it has higher Energy efficiency ratio. Also the Follow Me technology of Hitachi can help you keep the temperature of AC higher thus saving electricity (it will sense your presence and blow the air on your side).

      Hope this helps.

        What about LG BS-Q186C8R6 ?
        And are SHARP ACs reliable ?
        Just being curious and greedy to know as you have mentioned Sharp ACs in your various recommendations.
        I’m from Delhi and trying to buy my first ac.

        • Abhishek Jain says:

          Hi Arun,

          Sharp started selling ACs in India just a year back, but they have been selling ACs internationally since quite some time. They are focussing primarily on Inverter ACs in India (they have very few fixed speed models). Their energy efficiency ratios are quite high as compared to other brands. And we got a few good feedback about the models as well. That is why I have recommended it to people. But if you do not feel comfortable, you can go for any of the established (in India) brands. LG is a good brand. The model you listed has slightly lower EER than hitachi and that is why I recommended Hitachi. But you can go for LG as well.

          Hope this helps.

          Regards,
          Abhishek

        • Abhishek Jain says:

          Hi Arun,

          Sharp started selling ACs in India recently. They also manufacture in India to keep the price low. They mostly have inverter models and that too of various tonnages (0.75, 0.8, 1 , 1.1, 1.25, 1.5, 1.75, 2). Very few other brands offer tonnage less than 1 or between 1 and 1.5. And tonnage requirements of rooms vary and although inverter tech can cater to varying tonnage, but from a cost perspective, if your room’s requirement is 1.3 tons and you can get a 1.1 ton inverter AC for less, then why go for 1.5 ton (unless you are not happy with the brand itself). In case of fixed speed ACs, putting a 1.5 ton AC for a requirement of 1.3 ton means not running the AC efficiently. In such case even if you put a BEE 5 star AC, it will be as good as BEE 3 star AC of 1.3 ton. That is when inverter tech works well and you need ACs of mid tonnage range. Plus on top of it we observed that Sharp has quite high EERs (Energy efficiency ratios) as compared to similar tonnage models in other brands.

          Now we got a few good feedback on Sharp and that gave us confidence on recommending Sharp. But it is new and if you are not comfortable then even LG is a great brand. You can surely go for LG as well.

          Hope this helps.

      Hello Mr Ram,

      Sorry I did not see your next message before replying. Room 2 needs a 1 ton AC, whereas Room 2 needs about 1.2 tons of cooling. If you are concerned about energy saving, then you should go for Inverter tech AC. If you go for inverter tech, a 1 ton inverter tech AC will be good for both the rooms. You can go for any of these models:

      Sharp AH-X13PET (1.1 ton inverter tech compare india price Rs 32100)
      Sharp AH-XP13PMT (1.1 ton inverter tech snapdeal price Rs 30813)

      There are no cons of 1 ton inverter AC. Best thing about inverter AC is that it can adjust its tonnage and adapt accordingly. Just that you pay more to buy a 1 ton AC :).

    • Abhishek Jain says:

      Hello Mr Guruprasad,

      As per the size of your room and the other conditions, a 1 ton AC would be good enough for the room. Now as it is a guest room, I think the use of AC will be less. Now we typically do not recommend going less than BEE 3 star AC, but in case of window Air Conditioners, the star rating is one level low (or BEE 5 star rated window AC has similar energy efficiency as BEE 4 star rated split AC). So here are some models that can be good:

      1 ton BEE 5 star rated window AC (equivalent to BEE 4 star split AC):
      Whirlpool Magicool Platinum V (1T)

      1 ton BEE 3 star rated window AC (equivalent to BEE 2 star split AC):
      Onida 1 ton 3 star W123TRD
      Carrier Estrella Plus GWRAC012ER030

The guest bedroom is 150 sq ft and has french windows. However, the guest bedroom window is east facing and gets on morning sunlight. Also can you suggest me the brand? I am planning to go for Hitachi ACE Inverter. Thanks for your help.

    • Abhishek Jain says:

      Hi Abhijit,

      You need a 1.5 ton inverter tech for the bigger room and 1 ton for the smaller room. Hitachi is a very good brand. Instead of Ace I would suggest that you look at Kampa or iClean inverter versions from Hitachi.

      Hope this helps.

      Regards,
      Abhishek

      • Abhijit says:

        Thanks Abhishek. Can you tell me why kampa is better tha Ace. Also, I was reading somewhere that the iClean feature is not the great and still regular servicing is required. What’s your take on iClean?
        For 1 ton inverter I liked sharp inverter as well. Can I go for it?

        • Abhishek Jain says:

          Hi Abhijit,

          My apologies, I told you the reverse. You should go for Ace and not Kampa. And the reason for the same is that Ace has higher Energy Efficiency Ratios (1 ton has COP of 4.00 and 1.5 ton has COP of 3.8), Kampa has lower EERs (1 ton has COP of 3.8 and 1.5 ton has COP of 3.5), iClean has EERs of (1 ton has COP of 4.00 and 1.5 ton has COP of 3.73). So Ace and iClean have higher EERs than Kampa.

          As far as servicing is concerned, it is required for all models. A cleaner AC is usually more efficient in cooling as well as gives better air quality. So it is a good feature.

          Sharp is also offering some of the most energy efficient ACs. And on top of that they are quite economical as well (much economical as compared to Hitachi). We have also received some good feedback about sharp. So if you like it, you should certainly go for it.

          Hope this helps.

    Hi Abhishek,

    I live in Khar (W) Mumbai,I am looking for a split ac for my room of size 11*8 sq ft situated at ground floor
    , 3 floor building, no direct sunlight.
    Room is facing toward West

    I have 2 window(1st window 6*3.5 sq ft and 2nd window 2*3.5 sq ft), 1 door and room is connected to my Kitchen.

    My usage are primary in the night time in Summer season(April to June) and October for 5-6 hours.
    Considering my usage are not high 1 ton 3 star or 5star would be idea

    I have listed out Diakin 1 ton 3 star FTC35PRV16(R-32) and 5 star FT35MV16(R-22)

    should I go for inveter ac? Pls suggest
    Budget ard 35K

    • Abhishek Jain says:

      Hi Sachin,

      Your room of 11×8 sq ft just needs 0.6 tons of cooling. If you plan to go for fixed speed AC, I would suggest that you do not go for anything bigger than 0.75 or 0.8 ton. Now if we look at your calculations:

      Your usage is about 8 hours for 3 months, so 720 hours, and another 180 hours in october. So in total 900 hours.

      A 0.75 ton AC would consume about 0.5-0.6 units in an hour. So yearly electricity consumption would be about 450-500 units. Your per unit rate will depend on who is your electricity supplier (Tata or Reliance) and also on your monthly usage. For calculations I assume that it is about Rs 6.5 per unit.

      So yearly Rs 2925 – 3250 for electricity. A BEE 5 star would save about 15% or Rs 450 per year and Inverter tech would save about 30-40%, so about Rs 900-1000 per year. A BEE 3 star 0.75 ton AC from a good brand would cost about Rs 25000 and Inverter Tech would cost about Rs 27000 (Sharp AH-XP10LV would cost about Rs 27888 and Daikin 0.75 ton Inverter Tech is about Rs 28611).

      So I think it is better to go for Inverter Tech, but would suggest not to go for 1 ton but for 0.75 ton AC (even if you go for fixed speed).

      Hope this helps.

    • Abhishek Jain says:

      Hi Shalini,

      You need anywhere between 1.5 ton (if your room is on lower floor where ceiling is not exposed to sun, less sunny or less hot in general) to 1.9 ton (if the room is top floor with ceiling exposed to sun, sunny or gets quite hot).

    • Abhishek Jain says:

      Hello Mr Modi,

      You need 1.1 ton of cooling for your room. If you go for fixed speed AC, I would suggest that you go for a 1.2 ton AC rather than 1.5 ton AC. Else you can also go for 1 ton inverter tech AC (as most of them have a range of coverage from 0.2 to 1.15 tons). If you go for 1 ton inverter tech, then Sharp and Samsung will be good and most economical.

  67. Roy says:

    Hi Abhishek,

    I live in kolkata and planing to buy an inverter (hot & cold) 1 ton split ac unit for my bedroom and my budget is around 50k. There are 2 models that I have sorted out. One is Daikin FTXS35EVMA Heat Pump Series and another is LG Inverter V series AS-W126B1U1. Both AC have around the same price of my budget. Features are more in that LG model than in Daikin one. Though I like Daikin more but can’t ignore LG’s rich features. So need your help. There is also a Hitachi hot & cold inverter model available in the market but the price is out of my budget. And I am going to buy it by this weekend. So hope you can help me out on these.

    • Abhishek Jain says:

      Hello Mr Roy,

      The LG model has significantly higher EER (Energy Efficiency Ratio of 4.08 as compared to 3.43) than the Daikin model. So I would suggest that you go for it.

      Regards,
      Abhishek

      • Roy says:

        Thanks for your reply. But due of unavailability of that LG model I am still waiting and running out of time. So I am considering now in between Hitachi Ace Inverter RAU013EUEA or OGeneral Inverter ASGG12JLCA model along with my Daikin Heap pump series model. And when I queried about my hot & cold model in many stores, they suggest me its not that popular concept in Kolkata zone and hence the unavailability. Most of the people suggest me now only go for inverter cooling only model. So I need your suggestion on that. Is there much difference between hot & cold Inverter split ac and just inverter split ac? Also I would like to know about Refrigerant R410A and R32. What I learn that R32 is for future and most environment friendly than compare to R410A. And within a year most of the companies in our country will be using R32 only. I have found few R32 model in daikin sites (). So should I go with that or stick with more reliable R410A model? Hope I will get your reply on that.

        • Abhishek Jain says:

          Hello Mr Roy,

          Both R32 and R410A are HFCs and energy efficient and environment friendly. R32 is Daikin’s self manufactured refrigerant.

          As for hot and cold, you need it only if you have extreme cold climate (which I doubt you will have in Kolkata) and you need heating in winters. People in North India prefer to go for it (and it is actually good for them to go for it). In Kolkata I think just regular inverter model would be sufficient. Hot and Cold models are expensive too.

          Now if you are living close to river/sea I would suggest that you look for a model which has copper body as aluminium body rusts faster. So do check that before buying.

          Finally between Hitachi and General: I have seen far more energy efficient models in Hitachi so I do have certain bias for it. But you should find out which one provides better service in your area.

          Hope this helps.

            Hello Abhishek,

            Thank you once again for your detailed reply. Yesterday went to a store and have booked for LG Inverter V 1 ton model BS-Q126B8A4. Though I was like 100% sure that I would go with Hitachi Ace Inverter RAU013EUEA since it has more higher COP (4.00) than the LG inverter V series model I choose (3.43) as well as power consumption 945 is in Hitachi to 980 in LG. But after sale service is very important to me and what I heard that LG after sale service is much more superior than the Hitachi. I am still not getting my LG ac because of the unavailability and probably would get it after 20th of April as per the sales person. So I have time to rethink my decision whether its correct or not. Both Hitachi and LG inverter model price are in the same range.

            Here I am sharing both models link in the following:

            I am just like need one more favor from you to find out which model will saving money and also going to give me superior comfort as well as after sale service. If you 100% suggest me to go with Hitachi then I might cancel my LG advance booking and then go with the Hitachi one. So looking for your help. Thank you, Roy

          • Abhishek Jain says:

            Hello Mr Roy,

            LG model has more air filters to improve indoor air quality when the room is closed (mostly for a longer time). Whereas Hitachi model has lower power consumption and faster cooling (LG cooling watts = 3.43×980 = 3361 and Hitachi cooling watts = 4×945 = 3780).

            So pros for LG model:
            1) Better service
            2) Good air filters for improving indoor air quality.

            Cons for LG model:
            1) more power consumption
            2) Slower cooling

            Pros for Hitachi Model:
            1) Lesser Power Consumption
            2) Faster cooling

            Cons for Hitachi Model:
            1) Post Sales service not good
            2) No mention of air filters

            Hope this can help you make a decision.

    Hi Abhishek,

    Really glad to see that a forum like this exists and appreciate all your sincere responses.

    I reside in Kolkata and am planning to buy an ac(budget : around 32k) for my room measuring 10*10 ft and directly facing east and north. My usage of the ac would only be limited to a maximum of 5-6 hrs with the majority of it being used at night for around 3 months in a year. Now my first dilemma was to go for a window ac or a split ac. I have heard that a split ac demands a lot of expensive maintenance which I see as a big disadvantage. I reside on the fifth floor of a six floored apartment and the outdoor unit can only be installed on the terrace. But I have somehow been coaxed by family members to go for a split ac though I am not entirely convinced. What are your views on the same ?.

    Now I have come across some 3-4 models of split ac which I found good .

    1) Hitachi 1 Ton 3 Star Kaze Plus RAU312HUD (have heard a lot of negative things about Hitachi service though)

    2) Samsung 1 Ton Split Air Conditioner – 3 Star AR12HC3TFUR (the one with print on the panel)

    3) LG 1 Ton 3 Star (The new one with Himalaya cooling technology etc)

    4) Daikin 1Ton 3 Star

    Please, please help me select one out of these. What do you feel about the service quality of these brands in Kolkata.’

    And if you feel I should go for a window ac kindly suggest a model. It would of immense help if you can reply today itself as I might have to finalize the model by today.

    Regards,
    Sonal Jain

    • Abhishek Jain says:

      Hi Sonal,

      The maintenance of split AC should not very expensive if you have outdoor unit installed at a place where it is easy to access. In case there is no balcony, installers put an iron bracket outside the window to install the outdoor unit. Then it becomes difficult to service. May be in such cases it gets expensive. But I am not very sure of that. Typically there is not much difference in energy efficiency of window and split within the same star rating. And window ACs are slightly cheaper than split ACs. The difference is mainly in the noise as split ACs are a bit quite as compared to window AC.

      As for the brands, Japanese brands (Hitachi, Daikin, etc) have better technology, but LG & Samsung have a much larger service network (as they have outsourced most of their post sales service). If service quality is your major concern, then I would suggest that you go for LG/Samsung. Between the two I would prefer LG but again it is my preference based on my past experience with the brand.

      A BEE 3 star AC works fine for your usage. In case you want to go for window AC then you can look at Carrier Estrella Plus 1 ton AC. Carrier is another good brand. Please note, most manufacturers are slowly moving towards more of split ACs than window ACs and thus you will find very few window AC models.

      Hope this helps.

      Abhishek

        Hi Abhishek,

        Thanks for the really quick reply.

        A few more doubts still linger in my mind though. Is Hitachi Service in Kolkata really as bad as it is made out to be by the ac dealer(he is suggesting that I buy Samsung) or the dealers generally might have other reasons as well for pushing consumer brands like Samsung. ?…. I have a few people who really love Hitachi service which confuses me even more..

        And is the difference in technology and quality between Hitachi and Samsung/LG substantial enough to sway one’s decision ? I am looking to strike a balance between quality and service before arriving at a decision. Hope you can resolve the conflict in my mind quickly.

        Regards

        • Abhishek Jain says:

          Hi Sonal,

          The difference between the brands is like difference between Honda and Hyundai in cars or say Apple and Samsung in phones :). It is not substantial but depends on your preference. As for the feedback on service, I would prefer taking inputs from people who live in your area rather than taking it from a dealer. Dealers do try to push their inventory or products where they have better margins. Although I doubt that Hitachi’s service would be that bad in a city as big as Kolkata.

          Hope this helps.

  72. Anuj says:

    Dear Sir,

    I am living in Gurgaon and am looking for a Window AC. The room size is 13X15 ft (195 sq. ft) and glass window (size: 9X5 ft) is on EAST side. The room is on top floor and as it is rented accommodation, I can look for window AC only.
    I am planning to buy Hitachi RAV518HUD (1.5 ton ac), however as per the various website, it suggest that I should go for 2 Ton AC. Kindly suggest which AC I should buy 1.5 Ton or 2 Ton. My preference is to go for a 5 star AC.

    Thanks,
    Anuj

    • Abhishek Jain says:

      Hi Anuj,

      Even as per my calculation the tonnage requirement comes to 2 ton (in fact the range is 1.8 ton for non sunny/lower floor room to 2.25 ton for a sunny/top floor room). A 2 ton AC would consume anywhere around 1.5-1.8 units of electricity in an hour. So depending on your electricity rate and usage you can evaluate if you should go for BEE 5 star rated AC or not.

      Hope this helps.

      Regards,
      Abhishek

      • Abhishek Jain says:

        If it was not a rented flat, I would have suggested you to go for some insulation techniques to bring down the tonnage requirement. But some of those will be permanent fixes, so would be difficult to do in a rented flat.

        Regards,
        Abhishek

      • Anuj says:

        Thanks for you suggestion. I am just wondering if there is any 2 Ton AC with 5 star rating. Pls suggest, what if I will go for a 5 Star 1.5 ton AC? Is there any drawback in this option.

        Regards,
        Anuj

        • Abhishek Jain says:

          Hi Anuj,

          If you go for 1.5 ton AC then it will not cool the full room during peak summer days. It will just throw cold air locally (area about 7-8 ft from the AC). Not all corners of your room will feel cool on such days. However having said that, it is also possible that during low heat summer months like march, the tonnage may be sufficient for cooling the full room as well.

          If you are looking for a 2 ton BEE 5 star rated AC, then you can look at Hitachi RAU524ITD.

          Hope this helps.

    • Abhishek Jain says:

      Hi Pritam,

      Inverter Tech is the most energy efficient (electricity saving) technology available in the market. And Samsung is a popular brand in India. So you should definitely go for it. They have a large service network as well, so it will be easy for them to provide service in any area.

    Hey,
    I’m from pune. I’m looking for a split ac for room size 100 sqft. My house is on the third floor With one two sided window and its not that sunny but still we can feel the heat from above. usage could b 6-10 hours. as far as I have researched 1 tonn would be sufficient with invertor technology. Can anyone help me with the reliable brands in India with a good after sales service. The reviews I read about godrej and voltas were shocking I lost all hopes to buy an ac.

    • Abhishek Jain says:

      Hi Nitya,

      1 ton inverter tech is more than enough for your room. You can even go for a 0.8 ton inverter tech AC (one model available from sharp). There are several brands that have 1 ton inverter tech AC in 35K. You can get Sharp (0.8 ton, 1 ton and 1.1 ton models), Daikin (1 ton model) or Carrier (1 ton model) inverter tech in 35 K:

      Sharp AH-XP13LV Max tonnage 1 ton, Price about Rs 31,700 (on compareindia)
      Carrier Kurve Inverter AC, Price about Rs 35,488 (on compareindia) — Carrier also has a superia inverter range for which price is not known to us.

    Hi Abhishek,
    I stay in Jamshedpur in my own house. My room measures approx. 10 *12 sqft. Please suggest the right specicification to purchase a split AC. My budget is 25000/- to 32000/-. Also suggest the brands which are best in those segments.

    • Abhishek Jain says:

      Hi Immanuel,

      For your room, the tonnage requirement would be about 1.1 ton (if room is non sunny & lower floor) to 1.4 ton (if your room is sunny & top floor and gets quite hot). Now 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 (with traiff more than Rs 5), it is better to go for higher efficiency models.
      3) Brand: Some brands offer better reliability/technology and some have better service network. One has to factor in both.

      Hope this helps.

    • Abhishek Jain says:

      Hi Nalini,

      For the 100 sq ft room, if it is not too sunny and not on top floor (where ceiling gets hot), then it needs about 0.7 tons of cooling (during the day). For the 150 sq ft room, again if it is not too sunny then it need about 1.1 ton of air conditioning. In fact if you use it only during the night, then even a 1 ton AC would do. Now 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 (with traiff more than Rs 5), it is better to go for higher efficiency models.
      3) Brand: Some brands offer better reliability/technology and some have better service network. One has to factor in both.

      Inverter Tech is the most energy efficient AC technology (can save up to 30-40%), but its economic viability will depend on the usage you have of AC.

    Can you tell whether this would be a good decision to buy this AC? Me n my husband are worried about energy effiency as well as a brand with good after sales services.

    Thanks,

    • Abhishek Jain says:

      Hi Subhashree,

      Firstly your room would need about 1.35 tons of cooling in peak summers. So the obvious choice is to go for 1.5 ton models. Now there are several other factors as well that need to be considered while choosing an AC:

      1) 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 (with traiff more than Rs 5), it is better to go for higher efficiency models.
      2) Brand: Some brands offer better reliability/technology and some have better service network. One has to factor in both.

      Invertor Technology is the most efficient technology available in air conditioners these days and can save 30-40% on electricity bills. But the economics again will depend on your usage of AC. If you can tell us your usage of AC then we can analyze more.

    Hi Abhishek, Nice post.

    I a looking forward to buy Split AC for my room, which is 120sqft, Top floor (3rd) and have 1 window of 15sqft & 4 doors of 19sqft. Worst conditions for AC. I live in Pune. I did some research on web and found out 1.5 Ton/18000Btu is suited for my room. So I am looking for 1.5Ton 3 star with most EER rating in Cheapest price with R410A. I have found out that Except Blue-star all other manufacturers like LG, Panasonic, Daikin, Voltas uses R410A only in Iverter Models & not in regular split AC’s.
    Please tell me what would be the unit consumption of 1.5 Ton 3 Star AC with 3.24 w/w EER rating (3HW18HAF Blue-Star) Compared to 1.5 Ton Inverter AC with 3.30 w/w EER rating. My usages gonna be 6Hrs a day so, 6×30=180 Hrs/Month. Shall I go for 3HW18HAF (because it comes with R410A) or with Inverter ones (out of my budget)? Or with Panasonics New AC series Econavi which claims most Energy efficient?
    Thanks,
    Aniket.

    • Abhishek Jain says:

      Hi Aniket,

      First of all I must say that 1.5 ton for a 120 sq ft room in Pune is huge and you will end up using a lot of electricity for it. Even a 1 ton AC would be good enough for you (if you keep the windows and doors closed while using the AC and also use curtains). If you go for a BEE 3 star 1.5 ton AC, it would consume about 1.2-1.3 units an hour, whereas a fixed speed 1 ton AC would consume about 0.8 units. Secondly Inverter tech is a variable tonnage AC and it reduces its speed as per the need of the room. Also the need of the room changes from month to month. And thus inverter tech saves 30-40% electricity. A one ton inverter tech AC can change its tonnage in the range of 0.2 tons to 1.15 tons. And a 1 ton inverter tech AC can easily come in the same price range as a BEE 3 star 1.5 ton AC (Daikin, Carrier and Sharp inverter tech are quite reasonable in price). In case you are only interested in a certain type of refrigerant, then I would say you should go for 1 ton inverter tech.

      Hope this helps.

        • Abhishek Jain says:

          Hello Mr Sharad,

          Your usage is about 1200 hrs a year and in Maharashtra the tariffs are high, so BEE 5 star or inverter tech would be recommended. In case your room gets too hot and sunny in summers then you need about 1.3 tons of air conditioning in peak summers (as you are on top floor). Now most 1 ton inverter tech have a range between 0.2 ton to 1.15 ton (one sharp model AH-XP13LV has range up to 1.25 tons). Going for 1.5 ton inverter tech is safe but it will cost about 8-10K more. A fixed speed 1.5 ton AC would cost about 4-5K less than 1.5 ton inverter AC, but that will increase electricity consumption. So your choice truly depends on your budget. A 1 ton inverter tech model would cost between 30-40K whereas 1.5 ton inverter tech AC would cost about 40-50K.

          Hope this helps.

    hello im planning to purchase 1.5ton (3/5 star) split air conditioners. but im confused with brands like LG, Bluestar,Hitachi, Ogeneral. please help me out which brand will be best suited for me in terms of good service, more reliability, budget around 35k. please help me on which models should i prefer

    • Abhishek Jain says:

      Hi,

      First of all there are several factors to be considered before buying an Air Conditioner. An oversized air conditioner can increase your electricity bills, whereas undersized AC will not cool the room properly. Few aspects that are very important for sizing are: Room Dimensions (volume) and Location. Secondly a 3 or a 5 star preference will depend on your usage of AC as in how many hours in a year would you use them and what is the rate of electricity in your city. As far as brand is concerned, my preference will be more for Japanese brands, but that does not mean that other brands cannot offer good products, and all of us have different experiences with different brands.

      Hope this helps.

    HI, I have bought LG LSA3ZR3M1- I am confused with cooling(watts) of 3350 and power input (watts) of 1130. So in 1 hour and in 1 unit how many watts it will consume? 3350 or 1130?

    • Abhishek Jain says:

      Hello Mr Gupta,

      Cooling watts is the tonnage of AC. 3350 watts of cooling is equal to 0.95 tons of Air Conditioning. The input wattage is 1130, which means when the compressor and fan is on, it would consume at the rate of 1130 watts. Now watts is just the rate at which electricity is consumed. Actual electricity consumed will depend on the cycle time of your AC and many other factors as highlighted on our page:

      http://www.bijlibachao.com/Air-Conditioners/things-that-impact-electricity-consumption-in-air-conditioners.html

      With just the wattage one cannot tell the hourly consumption of the AC. Just based on observations, I can tell you that it would consume about 0.7-1 unit of electricity depending on outdoor temperature, room size, and various other factors.

      Hope this helps.

    For hot walls, leafy vines are good but cost water and space. Any kind of screen, set even a half an inch off the wall will protect the real wall for turning sunlight into heat (which would then enter the living space). Suddenly summer is here in Concord, CA.

    Hi Abhishek,

    I reside in Kolkata, my usage of AC is 7-8 hours in a day and my electricity bills comes around 4000-4800 rs!!

    For 10 hours, 2 computers are on! can you pl suggest what can be done to reduce electricity cost.

    Regards’

    • Abhishek Jain says:

      Hi Shweta,

      Tariffs in Kolkata are high. Having said that it does pinch when your electricity bills are too high. Air Conditioners can significantly contribute to electricity bills. We have listed down a few things that impact electricity consumption of air conditioner in our article: http://www.bijlibachao.com/Air-Conditioners/things-that-impact-electricity-consumption-in-air-conditioners.html

      A few things that can help:

      1) Higher the AC temperature lower is energy consumption. So try to increase temperature of AC to the point it is optimum comfortable. You can use ceiling Fan with AC so that increasing temperature does not impact comfort level too much.

      2) Check for walls or windows that are hot when the ACs are on. You can touch the walls and windows and see if anyone is hotter than others. For windows you can try to use thicker curtains. For walls, you may try thermal insulating paints or wall papers. Any heat from walls/windows increases electricity consumption.

      3) Close all doors, windows and wardrobes when AC is on. Make sure the room is clean and most of the things are kept in the wardrobe. A stuffed room will need more electricity to cool.

      4) If your air conditioner is old (12+ years), you may think of replacing them with new energy efficient ones.

      5) If you have incandescent lamps, you may want to change them for CFLs or fluorescent tubes.

      6) Finally from my personal experience, I have seen good amount of savings in electricity bills by using: T5 tube lights, BEE 5 star rated fans, efficient ACs with energy saver mode and using all energy efficient appliances.

      Hope this helps. You can email me at [email protected] in case you need more help.

    Mumbai’s climate is very humid and at the same time there is lots of dust everyday.
    Which 1.5 ton window is best suited with best EER .
    Is there any window airconditioner with inverter ?

  94. tushar says:

    @abhishekjain203:disqus then it means Hitachi RAV518HTD best in 1.5T Window AC for Effective Cooling, highest EER = 11.27. Right now im using Samsung window AC 1.5T running continuously for 10 hours still not able to maintain Temp 25 room size is perfect for 1.5T, dispense cool air is not chill enough.

    • Abhishek Jain says:

      Hi Tushar,

      1.5T is a decently big size unless your room is huge. If it is a new AC, I would suggest contacting Samsung for it. If it is very old (12+ years) then it might be time for you to change it. Else something might have gone wrong. When the compressor is on, the chillness of air is the same at 25 degrees or 18 degrees. The only difference between the 2 thermostat settings is the time for which the compressor runs. At 18 the compressor will run longer, but at 25 it will have shorter cycles. But the chill factor of the air coming out remains the same.

      • tushar says:

        Dear Abhishek,

        Samsung AC 5 years Old but chill factor coming out not like other LG AC installed in other room with same 1.5 window AC. Planning to buy new Window AC more interested in Hitachi RAV518HTD 1.5 expecting more chilled air as per its Specification. What you suggest which one will be the best for chilling AIR :)

        • Abhishek Jain says:

          Hi Tushar,

          5 years is too early for an AC to die down. But if you are interested in buying a new AC, then the model you selected has good cooling capacity with right efficiency.

          Regards,
          Abhishek

          • tushar says:

            Just purchased Hitachi RAV518HTD for Rs.32500 + Stabilizer Rs.2300 + Rs.500 installation (6 Years Replacement Warranty)

          • Anand Gupta says:

            Hi Tushar! Can you share the info – number of hours you use the AC and the power consumption by the AC?

  95. Irshad says:

    @abhishekjain203:disqus : My room size is 146 Sq ft and 12 ft height in ground floor. There’s window to west with glass covered with curtain. My room’s entrance door faces east with no trace of sun light. And i have a ventilation (3.2 sq feet to 3.4 sq feet) closed with mosquito net on west at room top. Its only me and my pc all year around. I would be using A/C between the temperature of 25 celsius to 28 celsius mostly as i am sensitive to chillness. I am in dilemma, whether to buy 1.0 ton or 1.5 ton invertor A/C ?. I zeroed on Daikin and LG Invertor A/C. Your help will be appreciated……

    • Abhishek Jain says:

      Hello Irshad,

      I am glad that you are considering inverter tech AC. It is the most efficient technology that is available in the market and can greatly help you if you have a good usage of AC. Sharp has come out with an excel based calculator for sizing inverter tech AC which is available on http://www.sharpproducts.in/downloadsupport.aspx?id=23&cid=13. Let me know if you are not able to download it, I will send it to you in email. Inverter tech AC is a variable sized AC, so a 1.2 Ton AC can go up to 1.5 Ton and can also go as low as 0.7 ton (please note that these are just a representative numbers to help you explain, the actual numbers vary for models but are close to these). So if a calculator for regular AC shows you about 1.5 ton requirement, then an inverter tech AC of about 1.2 ton would suffice your need. Try out the sharp calculator. I hope it helps you.

      Regards,
      Abhishek

    thx abhishek for ur reply.. i have one more q? when in doubt should one go for a lower tonnage of ac or a higher tonnage?

    i have zeroed in on a INVERTOR ac : AHXP13LV by Sharp (thx to your timely article). http://www.sharpproducts.in/overview.aspx?id=17&cid=13 . now my question is sharp claims according to my room requirement 1.1 ton invertor ac is good (they have a chart which shows 1.1 ton invertor ac is good enough for room size upto 160sft if in ground floor). my room is 150 odd sft and is in ground floor. (its a 10 floor apartment). window direction west.

    but other calculators say its 1.5 tonn..! so wats your take ?

    • Abhishek Jain says:

      Hi Ravi,

      When in doubt it is better to go for higher tonnage. In case of lower tonnage, the compressor will keep running all the time consuming lot more electricity.

      Now in your case, you are choosing an inverter technology Air Conditioner. The benefit of Inverter tech is that it has a variable capacity. So an AC market with 1 or 1.1 ton may take capacity of 0.75 ton to 1.5 ton (you may check the AC manual to get the exact details). The benefit of the same is: With varying seasons, the cooling requirement of a room varies (peak summers there is more heat, and in cooler months it is less, it may vary even between day and night). Thus ideally the tonnage requirement varies (because tonnage signifies cooling capacity).

      So if you are taking non inverter tech AC, then try to go for the higher tonnage (to manage the peak load). Ideally if it is a 150 sq ft room and you are going for a non inverter tech AC, then even I would suggest a 1.5 ton AC. But that’s the benefit of inverter tech that you need smaller sized AC and it can vary the capacity based on load.

      Hope this helps.

      Abhishek

      • ⚡Ravi Dabbiroo ZYCE⚡ says:

        thanks abhishek ..for the super prompt reply ! i have decided to go for the inverter ac for sure. so wat you saying is1.1 ton should suffice (coz it has variable capacity) ! the manual says that inverter tech 1.1 ton is good upto 160 sft room (and in case of non-inverter it shld be 1.5t)…!

        so 1.1t inverter ac should suffice my requirement and sharp ac fits the bill!

        ps: i have got all 5 star rated as per latest guidelines ceiling fans installed as per bijlibachao ..! great going team..!

        wd look forward to your views on the 1.1T dilema that i am in !

        best,
        ravi

        • Abhishek Jain says:

          Hi Ravi,

          If you plan to use AC all throughout the year, then you should think about Inverter AC (because loads will vary with seasons). If you will use it only in the summer months, then a regular air conditioner will also do. You can go for a better technology brand (like OGeneral, National, Blue Star, Hitachi or Carrier) with a good star rating and can go for a 1.5 ton AC. Please note that determining the tonnage depends on a lot of factors and exact calculation is extremely difficult. Most calculators just go by the thumb rule calculation which give closest possible best guess. Hope this helps.

          Abhishek
