Electricity Saving Tips For Homes And Offices

Tips to choose the best brand air conditioner

By on August 26, 2015

Hindi Translation: सर्वश्रेष्ठ ब्रांड एयर कंडीशनर का चयन करने के लिए कुछ युक्तियाँ

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

Air Conditioner

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

Air Conditioner brands that are known for their air conditioning technology

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

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

Generic brands that are into multiple appliances

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

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

Inexpensive brands

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

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

Here is a short video for tips to buy the best air conditioner in India

    Please enlighten me Sir as your decision will be Final !!!

    Great Regards

    • Bijli Bachao Team

      1.5 ton will be better for you and Carrier 365 AC has good efficiency and it is also a good brand.

  • MANOJ MINZ

    since my job is transferable; I many not get rooms of same size every time. hence, I cannot calculate the tonnage. Just to be safer side I think 1.5 ton ac shall be the good option. my main concern is reduction in monthly electricity charges. presently I am using LG window ac, but the electricity bill is very high, hence I want to replace it with inverter split ac. please guide me. presently I am living in Chennai. Please tell me about Bluestar AC.

    • Bijli Bachao Team

      Blue star is a good brand. However you can look at top 10 most efficient inverter AC on this link: https://www.bijlibachao.com/top-ten-appliances/best-air-conditioner-ac-window-split-hitachi-lg-carrier-samsung-electricity-consumption-tonnage-in-india.html

    • Bijli Bachao Team

      Hi Rohit,
      We recommend you to buy your AC from authorized dealers. They would sell genuine products only.

  • RAJNIKANT R ROHIT

    hello bb team.

    lives in ANAND,.GUJARAT…388120.

    ROOM; L-17*B-10*H-10.

    ROOM FACES DIRECT SUNLIGHT FROM WEST AND EAST.ROOM IS SITUATED ON THE FIRST FLOOR.TERAACE FACES SUNLIGHT WHOLE DAY

    MEMBERS; 4

    USAGE- 8-10 HOURS FOR SIX MONTHS

    NOW MY PROBLEM IS DIFFERENT,

    I PURCHASED DAIKIN- THREE STAR-SPLIT AC –1.5 TON ….LAST YEAR.

    MODEL/YEAR :-FTC50PRV16+RC50PRV16/2014

    IT CONUSUMES 2 UNITS PER HOUR. HERE UNIT RATE IS 5.20 RS IF UNITS ARE OVER 250. I USED 900 UNITS FOR LAST TWO MONTHS AND GOT THE

    HIGHEST ELE. BILL.I FEEL IT WAS MY WRONG CHOICE AND DECISION TO GET 3STAR .AS IT CONSUMES MORE ELECTRICITY.AS I WAS IGNORANT ABOUT

    BIJLI BACHO SITE AT THAT TIME.OTHERWISE I WOULD HAVE BEEN ABLE TO MAKE RIGHT CHOICE. I AM IN DILEMA.

    NOW MY BURNING QUESTIONS ARE :

    1] WHAT SHOULD I DO TO SELL THIS AC AS IT IS ONE YEAR OLD.

    2] WHICH AC IS APPROPRIATE FOR ME?

    3]SHOULD I CONTINUE WITH THE SAME ONE?

    • Bijli Bachao Team

      Hi Rohit,
      According to our calculation your room requires a cooling of 1.5 tons during night time and about 1.8 tons of cooling during peak summer daytime.
      A BEE 3star 1.5 ton AC should consume about 1.4 units in daytime and about 1.3 units during night time. So a 3star Daikin AC should not consume 2 units/hrs. So we suggest you to contact Daikin service centre and ask them to check the AC.
      We typically recommend people to go for inverter AC if usage is more than 1500hrs/year and tariff is about Rs5/unit. So for your usage a 1.5 ton inverter AC would have been ideal for you.

      once again thanks for useful information

      1] as far as my city and location concerns which brand and model will be appropriate for me?

      2] room position–north and south–lenght is 17….and east and west–b-is 10..and h-10…so on on which side installation can be done so that ac can work efficiantly.

    • rajnikant r rohit

      brand and modal which consume the least electricity….as you know that was my the biggest problem.

    • rajnikant r rohit

      thanx ..lots of love.

    • Bijli Bachao Team

      Hi Mr Rohit,
      We suggest you to install the AC in the middle of the the side with 17ft length as it will be able to cover the most of the room from there.
      The above 1.5 ton inverter models given in the list are based on EER.The model with highest EER is on the top. So the model with the highest EER will be most energy efficient. All the brands given in the list are good you can go for any of the brand you like and which has got good after sale service in your area.

  • Uday

    i live in burdwan (West Bengal). My room size is 14×10 feet on first floor. South and west walls are exposed to sun all day. I have planned to buy Hitachi RAU514HUD 5-star split AC. Please suggest whether my room needs 1.2 tons or 1.5 tons of cooling

    • Bijli Bachao Team

      You should go for a 1.5 ton AC for your room. Hitachi RAU514HUD would be a good option.

    • Uday

      Thank you very much. Please tell me whether Hitachi uses aluminium or copper coil. And which one is better in humid areas? And I am confused whether Hitachi or Voltas SAC 185EX would be better. Does Voltas use copper coil? Please help me to decide.

    • Bijli Bachao Team

      Hi Uday,

      Hitachi and Voltas both use copper tubes in their latest models. Copper tubes will be better for humid areas. Which models of Hitachi and voltas are you comparing?

  • VEER

    Hi BB
    I Live in Punjab , My room size 14X12 on the ground floor with no direct sun light at any time of the day. I have installed Hitachi RAU514HUD ace Cut Out 1.2 ton split ac . It cools the room very quickly but it takes 5 to 6 hours to auto cut. Is it ok or I have installed an under sized ac ? Please clear. I always keep the at 27 degree.

    • Bijli Bachao Team

      Hi Veer,
      According to our calculation your room requires about 1.6 tons of cooling. So yes 1.2 ton AC is undersized for your room.

  • Giby

    Dear BB Team,

    In your opinion, how important is to vacuum the pipes while installing the AC? I see most of the installers are not performing it but I am told it is very important.

    • Bijli Bachao Team

      Hi Giby,

      It is quite important to do that. Installers must do it.

  • Nitin Mahajan

    Hello BB Team,

    I stay in Bangalore in an Apartment on 6th floor. There are 13 floors above our flat. Need to buy AC for two of the rooms, each not more than 120-130 SqFt.

    1. First room is in South-West and exposed to sunlight in afternoon through two large windows on both sides. Usage mostly for couple of hours in April and May in night almost everyday. Couple of hours in summer afternoons on weekend.

    2. Second room is in South-East and no exposure from East. Only a Window from West. Usage mostly for couple of hours in April and May in night almost everyday. Couple of hours in summer afternoons on weekend. Still would be lesser than the usage above.

    Kindly suggest a suitable AC and if I would need an inverter AC or not? If not, AC with how much star rating would be ideal.

    One of my major concerns is long term reliability and less hassles afterwords.

    Thanks in Advance….

    regards
    -Nitin

    • Bijli Bachao Team

      Hi Nitin,
      According to our calculation both your rooms requires 1 tons of cooling. Your usage is very less you do not require an inverter AC. For your usage we recommend you to go for a BEE 3star 1 ton AC.

      You can look at these BEE 3star 1 ton ACs.

      Brand Name Model Number EER (W/W) Price

    • Nitin

      Thanks so much.
      Typically for how much usage, one needs an inverter AC ?

      regards
      -Nitin

    • Bijli Bachao Team

      Hi Nitin,
      We typically recommend people to go for inverter ACs if there usage is 1500hrs/yr and tariff is about Rs5. Since your usage is very less a BEE 3star AC is ideal for you.

  • Ankit Kumar

    Hi BB team,
    I live in Mumbai, my flat is on 10th floor and it’s east facing, so we get direct sunlight for around 3,4 hours a day. I am planing to buy a split AC for my bed room, it measures around 14X12 ft. I have two models on my mind but I am unable to decide which is better.

    1. Hitachi RAU318HUDD Kampa series 1.5 ton, 3 star.
    2. Voltas 183CYa 1.5 Ton 3 Star Split AC

    As I am able to find many good reviews for Voltas model but unable to find much reviews regarding HITACHI RAU318HUDD Kampa series.(or what ever is available does not recommend the product )

    Kindly help me in deciding the product for which I should go..

    Thanks,
    Ankit Kumar

    • Bijli Bachao Team

      Hi Ankit,

      Is your flat on top floor or lower floor? Also how much is your usage of AC in hrs/day and month/year?

    • Ankit Kumar

      Hi,
      My flat is not on top floor, building is of 13 floors and my flat is on 10th floor, also my usage will be 8 hrs/day and 5months/year.

      Thanks,
      Ankit Kumar

    • Bijli Bachao Team

      Hi Ankit,
      According to our calculation your room requires 1.2 tons of cooling. So a 1.5 ton AC would be oversized for your room. Your usage is about 1200hrs/yr and tariff in Mumbai is also high. So based on your usage we recommend you to go for a 1.1 ton inverter AC. An inverter AC would be about 40-50% more energy efficient than a BEE 3star AC. It it would cost about same as a BEE 3star 1.5 ton AC.

      You can look at these 1.1 ton inverter ACs:

      brand model eer_ratio price
      SHARP AH-XP13PMT 3.83 37896
      SHARP AH-X13PET 3.83 32346

    Thanks a lot for your very helpful suggestion! I will be going for Carrier Superia now :-)

    • Bijli Bachao Team

      Great! Please do let us know your feedback on the same.

  • Rohan Desa

    Hello Bijli Bachao Team,

    I am from Mumbai. My room is 15*13, top floor, not facing to direct sunlight. Usage will be 8 hrs a day.

    I am thinking about Daikin FTF60PRV16 or Voltas 2.0 T 245 DY.
    Are these Copper coil or aluminum coil?
    Please suggest.
    Thank you.
    R.D.

    • Bijli Bachao Team

      Hi Rohan,
      According to our calculation you would require 1.5 tons of cooling during night time. And 1.7 tons of cooling during peak summer daytime. So we recommend you to go for a 1.5 ton inverter AC it would cost you same about a 5star 2 ton AC and it would be about 30% more energy efficient compared to a BEE 5star AC.

      You can look at these 1.5 ton inverter AC within 45k:

  • Priyanka

    Hello, I will be purchasing a 1.5 ton split AC ( BEE 5 star) for my bedroom and am looking towards a 8 hour usage over 5-6 months. My budget is between 40,000-45,000. I live in Guwahati where summer months get very humid. Having done some research myself and after speaking to the local dealer, I am confused about which brand to go for. While the local dealer is strongly recommending Godrej Eon ( GSC18FG5WNG) I am thinking LG might be a safer choice ( LSA5NPSA). What do you suggest? Also, will Carrier be a better choice, if so then is there a model which might be suitable in my circumstances? Thanks, Priyanka

    • Bijli Bachao Team

      Hi Priyanka,
      Both Godrej and LG uses Aluminium condenser. Which are prone to corrosion in humid areas. So we recommend you to go for Carrier or any other brand which uses Blue fin condensers.

  • Noor Shaikh

    Hi BijliBachao Team,
    Firstly I appreciate good work you are doing in conserving environment by making people aware of useful information towards achieving energy efficiency goals.

    I am looking for 1 ton or 1.1 Ton inverter air condition with good performance and longevity.

    My short listing of model is

    Brand Model EER Ratio (Cooling) Tonnage Price
    Sharp AH-XP13PMT 3.83 1.1 37896
    Sharp AH-X13PET 3.83 1.1 32346
    Sharp AH-XP13LV 3.83 1.1 31700
    LG BS-Q126B8R8 3.47 1 38900
    LG BS-Q126B8A4 3.47 1 37000

    After all the research I see all aluminium condenser with Rotary compressor is good. I would like to know out of above models which all are having all aluminium condensor.
    Built quality wise and service which brand has better rating in Mumbai.
    I have not been able to get the price listed above which I have seen in one of your replies to one of the queries. Please help to find such a deal near byculla area in Mumbai.

    I appreciate your help to get this information.Thanks in advance.

    • Bijli Bachao Team

      Hi Noor,
      Sharp uses copper coils and LG uses aluminium coils. Aluminium are highly efficient but they are prone to corrosion in humid areas. So if you want to go for aluminium condenser go for LG and if you want to go for copper condenser go for Sharp.

      You would have to check with your salesman for price in your region. We do not have a list for that.

  • biswa

    Hello BB team
    thnx for helping out people for choosing right ac for their need. I am a bank employee I need to install one ac abt 1.5 tonn and made up my for carrier duraedge+ but after hearing frm a sales dealer they opined me to go for a brand whch have a good service coverage as my transfers will be frequent and into some remote areas in my job. I am currently working at baramba, Cuttack which is abt 90 km frm bhubaneswar. Where there is frequent powercuts and might voltage fluctuations so i need your suggestions regarding this. I also want to know which brand has a wider after sales service coverage? N I also want to see my electricity bill at a lowerside at the end of the month. Please suggest me a perfect model n brand which has a low maintenance also.

    • Bijli Bachao Team

      LG, Samsung and Voltas would have the widest service network amongst all brands. Inverter technology Air Conditioners will have the lowest electricity bills but they will have slightly higher maintenance cost. The choice will depend on your total usage of AC in hrs/year. Also you will have to protect your AC from voltage fluctuations and surges if the power quality in your area is bad.

  • V.K.SETHI

    Recently KENSTAR Split AC’s with 1.5 T and 1 T rating with 5 star have come in the market. Any feed back on KENSTAR AC’s from your side in terms of star rating and technology

    • Bijli Bachao Team

      Hi Mr Sethi,
      Kenstar are new in the market in the field of ACs. We have got good user feedback that it works well. But the durability of Kenastar ACs has to be seen so cannot comment on it.

    • V.K.SETHI

      Any comments / evaluation done by Bijlibachao team on the star rating, Technology used and cooling coil materials used by KENSTAR

    • Bijli Bachao Team

      Hello Mr Sethi,

      Kenstar has models in all Star ratings. They even have BEE 5 star rated models having EER of 3.51 (barely 5 star :) ). They have PFC condensers so it is not copper, but is aluminium. They do not have inverter technology compressors, and they only have fixed speed compressors. They are new entrants in Air Conditioning space and have priced their products aggressively to get entry into the market. Their durability is yet to be tested as this is the first year we are seeing them in the market.

I am going to use this AC during summer nights only for about 5 to 6 hrs per day at moderate tempremature. I am from Kolkata where humidity during summer is too high. Please suggest the best tonnage, brand and rating of AC I should go for.
    I am using one 1.5 Ton 2 star LG split AC in my master bed room of same size but having lesser Sun light over walls since last 6 yrs. But it consumes more electricity. Please help ASAP.

    Thanks in advance,

      Hi Mr Sarangi,
      According to our calculation your room requires 1 tons of cooling if your usage is only at night. Since your usage is only in summers we recommend you to go for a BEE 3star 1 ton AC.
      1.5 ton AC is oversized for your master bedroom that is why it is consuming more electricity.

      You can look at these BEE 3star 1 ton AC for your bedroom :

    I am planning to buy Blue Star CNHW12CAF Interverter AC. (My requirement – 1 ton inverter ac for Bangalore weather) Can you please give more insights like should i go for it, how is this model and Is blue star ac works perfectly. Are there any other options in price range of 35-37k.

    Thanks

    • Bijli Bachao Team

      Hi Vishal,
      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 tariff more than Rs 5), it is better to go for higher efficiency models. Benefit of inverter tech is that it is a variable tonnage AC and as the tonnage requirement is different every month and every day, this AC auto adjusts to the needs and thus saves electricity.

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

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

    • dashingvishal

      I am in Bangalore, room size is 10*10, first floor, no floor above it, walls are exposed to sun for 4-5 hours from sunrise to noon, Usage approx – 15-16 hours daily, budget 30-40k (including installation and stabilizer etc)

    • Bijli Bachao Team

      Hi Vishal,
      According to our calculation your room requires 1 tons of cooling. Since your usage is very high we recommend you to go for 1/1.1 ton inverter AC.

  • Baikuntha

    Hi BB team,
    I am from Bhubaneswar, Orissa. I want to install an ac in 1st floor room size 15ftx18ftx9ft having window facing south of size 6ftx5ft. One steel almirah of size 8ftx4ftx3ft,One box bed of size 7ftx6ftx3.5ft occupies the room. one wall south side of the room faces sunlight during afternoon 7 there is another floor above the room in the building. pls guide me about the reqd toonage of ac and my usage being 6 hours at night for summer 3 months, pls also guide me about the star i shlould look for. I am really confused about brand selection. My budget being upto 40k and wanting an ac for tensionless 7/8 years durability. initially made up my mind for daikin or hitachi, but really worried about finding reviews in mouthshut about their poor service & so so bad things. pls guide me about the right brand having good service and durable product.

    Baikuntha

    • Bijli Bachao Team

      Hi Baikuntha,
      According to our calculation your room requires 1.8 tons of cooling. So we recommend you to go for a BEE4/3 star 1.8 ton AC. Forget Hitachi and Daikin almost all the brands will have negative feedback on mouthshut. Because most of the people who put reviews on the mouthshut are those who have had a bad experience with a particular brand. Very rarely would someone who have been using an AC for 4-5 years and is satisfied with his AC will put his review on mouthshut.
      There are two types of online reviews one is instant review like on Amazon and flipkart where people provide feedback immediately after purchase and another is when people experience problem with AC after a period of time and they put their review on mouthshut. It does not mean that Hitachi, Daikin or any other brand always have a poor service.
      We would recommend you to consult with your local dealers and your neighbours who have used the particular ACs to know about the particular brand of ACs services and quality.
      Since you are living in a coastal area you should go with an AC which has copper pipes and blue fin condensers.

      You can look at these BEE4/3 1.8 ton AC.

    • Baikuntha

      Hi BB Team,
      Thanks for ur quick response & very precise answer. Given to believe by some of the dealers that Hitachi & Daikin do not have any company service centre at Bhubaneswar & they only operate through 3rd party operated service centres not having expertise to handle above stated machines. pls guide if the above is true ! Also, pls confirm if LG, bluestar & voltas have 3 star models with copper pipes and blue fin condensers & amongst these 3 which will be best.
      Baikuntha

    • Bijli Bachao Team

      Hi Baikuntha,
      LG uses PFC condensers. Only Bluestar and Voltas use copper pipes and blue fin condenser.

      You can look at these BEE 5/3 star 2 ton ACs:

  • D.Ravikumar

    Hi Abhishek,

    I live in an independent house in Hyderabad. I would like to fix an AC in our bedroom ( 3 occupants) on the 1st floor (with open terrace on top).The room is 160 sq ft with 10- 12 ft high ceiling & glass windows of 63 sq ft and it is on the S-W side. I would be using the AC for 7 to 8 hrs a day. We do have power cuts & voltage fluctuation during Summer at this part of the City (22 km away from City)

    I would like to go for a branded AC Unit with is really energy efficient and durable; but it should also be reasonably priced ( budget below Rs 45000/-)
    Should I go for the 5 star rated Model or with an inverter. ? Which is more suitable for my room and usage ?. Kindly suggest a branded AC Unit with the right tonnage, energy efficient and durable.

    Ravikumar

    • Bijli Bachao Team

      Hi Ravikumar,
      According to our calculation your room requires 1.7 tons of cooling. If your usage is at night only you can go for a BEE 5star 1.5 ton AC or a 1.5 ton inverter AC. If your usage will also be at daytime, we recommend you to go for either a 1.5 ton inverter AC or a BEE 5star 1.7 ton AC.
      If your area has power cuts and voltage fluctuation we recommend you to go for a voltage stabilizer with good surge protection for your AC.
      Inverter ACs are about 30% more energy efficient compared to a BEE 5star AC. An inverter AC would save electricity compared to a BEE 5star AC even for one hour of usage so if it fits in your budget we recommend you to go for inverter AC.

      You can look at these 1.5 ton inverter ACs in the range of 45k:

      Dear Bijli Bachao Team,

      Thank you for your reply suggesting the right AC unit for my room on the first floor. Sorry for bothering you again; this is just an after thought. In case, if we decide to fix the AC in the bedroom (with same dimension-160 sq ft + glass pane of 48 sq ft ) on the ground floor with the room on the 1st floor, what would be the required tonnage of AC ? After reading through your suggestions, I think, I’ll be able to conserve power and save more if the AC with lower tonnage is used in the bedroom on the ground floor. Kindly give your suggestion in selecting the right AC unit .

      Thanking you in anticipation

      Regards,

      Ravikumar

    • Bijli Bachao Team

      Hi Ravikumar,
      Your room in the ground floor (160sqft) will require 1.4 tons of cooling. So you can either go for a BEE 5star 1.5 or 1.5 ton inverter AC.

  • abhijitmazumder

    Hi Abhishek,
    Looking for an ac to buy.

    City: Bangalore (Average summer temp 35 c. – 22 c)
    Floor: Top Floor
    Room size = 14*11.5 =160 sft
    Window Size= 5*4 south
    Direct Sunlight= Only on southern wall and of course on the roof
    Woodwork (cupboard) is on the north wall and after woodwork room size = 12*11.5 = 138 sft
    AC Usage = 3 months 4-5 hours in morning+ 10 hours at night/ Very sparingly other months
    Electricity Cost = 625 paise per unit

    Please let me know
    1. What tonnage I should by?
    2. Should I consider room-size after subtracting wood work or including wood work
    3. How much cooling I need?
    4. Do I really need to go for 5 star or 3 star is fine?
    5. Looking for a brand with decent after sales support. Technology is fine but peace of mind also matters.

    Please let me know

    Hi Abhishek,

    I have been struggling between models to pick the best. Can you let me know what is the best model and brand for a 120sqft. room

    I am primarily concerned about Air purification. I have looked into the Plasmaster Ionizer technology of LG but seen some bad reviews. Also, is the mosquito repeller actually effective?

    I am highly allergic to pollen and dust. Getting a unit which helps in odor control will also be great.

    With this, please advice on economy also in terms of power consumption and cooling etc

    Regards,

    • Dweep Sharma

      Just to add – I live in Bangalore. Will use the AC for 3-4 hours during the day and 8 hours at night.

    • Abhishek Jain

      Hi Dweep,
      Can you tell us which floor is your room, is it at a lower floor, or at top floor with direct sunlight falling on the ceiling? And what is your usage of AC in hrs/yr? And finally what is your budget? (This is important to calculate the tonnage required and the right model of AC for your room)

    • Dweep Sharma

      Hi Abhishek,

      My room does not receive direct sunlight falling on the ceiling.
      Usage would be – 8 hours per day average.
      Budget, i can stretch upto 50K.

      As i said, I want something that provides good air purification as i have problems with pollen and dust.
      Can you comment on Plasmaster Ionizer technology with LG.

      Regards,
      Dweep

    • Bijli Bachao Team

      Hi Dweep,
      According to our calculation your room requires 1 tons of cooling. A 1/1.1 ton inverter AC would be really good for you. Daikin and Sharp AC have good filters and therefore good air purification.
      About Plasmaster Ionizer technology we can only say what is written on LG website as we do not have any user feedback on it.

    Hello Abhishek!

    You are indeed doing a great job helping all of us out!

    I’m from Pune, looking for an inverter ac for bedroom size 13×10, top floor, no false roof, nothing. Gets heated up in summers.
    Window size 6×4 runs through the length of the room, west facing so direct sunlight from 1pm to 6pm. Planning to install on the side of the window as that’s the only place feasible. Top of the window is 2′ deep beam.

    Currently managing through a symphony cooler tho! Delayed buying one as I keep shifting every alternate year.

    Zeroed down to Samsung brand and an inverter ac as usage would be 5-6 hrs in the day and same in the night in Summers n monsoon.

    1. Not sure of the tonnage I shud go for
    2. Unable to decide the difference between inverter models ending with DAWK and NBWK, pls suggest any model u feel would be suitable
    3. Also, If these models have copper or aluminium coils and if there is corrosion coating
    4. Do I need a stabiliser for these models?

    Kindly advice

    Regards

    • Samar patra

      Dear Abhisek,
      I live in Mumbai and am planning to buy an split ac for my home.
      The room dimension is 15x12x12 feet. My flat is on the 3rd floor and have no floor above it.
      Two sides of the room (where A/C will be installed) is exposed to sun directly for whole day.
      Duration of use would be 4 hrs a day & 7 hrs at night for 4 to 5 months in a year.
      My budget is around 35K.

      Requesting you to provide me your expert suggestion in terms of tonnage, brand and model of the most energy efficient ac available in the market today.

      Also whether to buy online or from store?

      With Thanks & Regards,

      Samar

    • Abhishek Jain

      Hi Samar,
      According to our calculation your room requires a cooling of 1.7 tons. So you would need to go with at least a 1.5 ton inverter AC.
      Since your usage is high and tariff in Mumbai is also high we recommend you to go for inverter AC only. The cheapest inverter AC would cost around 40-45k

      These are some 1.5 ton inverter ACs in the range of 45k

      Wt s the difference btw daikin ftkp50prv16 and ftkm50prv16 both 1.5 ton inverter model

    • Bijli Bachao Team

      Hi Arul,
      Daikin ftkm50prv16 has better sensors and filters compared to daikin ftkp50prv16. Daikin ftkm50prv16 has basically ISEE technology which adjusts the temperature of the AC according to the movement of people.

    • Manish

      Thanks Abhishek for your suggestions.
      Are there good options in Lloyd and Voltas brand for inverter A/c
      Also please suggest if I should look for copper or aluminium condenser

    • Bijli Bachao Team

      Hi Manish,
      Lloyd and Voltas 1.5 ton inverter have comparitively lower efficiency compared to the models given above. Aluminium condenser are prone to corrosion when exposed to harsh climate like that in humid areas. So if you are living in humid areas we recommend you to go for copper condenser. Otherwise you can go for either copper or aluminium condenser.

    • Manish

      Hi BBT,

      I went to the dealer and he is recommending Panasonic YS18rky, 1.5T inv ac. Is it a good option worth considering?

      Thanks
      Manish

    • Bijli Bachao Team

      Hi Manish,

      The EER of this panasonic inverter AC is 3.16 which is low. In that case a BEE 5 star rated AC of EER 3.8 or above will be better or as good as this one. Panasonic has more models with higher EER and econavi sensors that are good.

  • Sankar Gupta

    Hi, I am planning to buy one AC for my home. Based on price offer I have chosen Hitachi Kampa RAU312HUDD Split AC (1 Ton, 3 Star). It will be great, if you can please advice whether this range of product outdated or it is correct for my home. Should I look for some other Brand or series such Kaze etc.

    Thanks in advance.

    Rgds
    Sankar

    • Abhishek Jain

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

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

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

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

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

    • Sankar Gupta

      Thanks Abhishek for quick responce.

      It will be in Kolkata, for use in my parents bed room. Room is in Ground floor, and size is 12X14 ft. One side of room wall gets only morning sun light. Another floor is also available on top.
      Average use will be in approx 4-6 hours a day during summer (April to October). Budget is around Rs30000/-

      Please advice.

    • Abhishek Jain

      Hi Sankar,
      According to our calculation your room requires 1.4 tons of cooling during peak summer day time. So if your usage is at night only we would recommend you to go for a 1.1 ton inverter AC as it will work relatively work in day time as well. Or you can go for a BEE 5 star 1.5 ton AC.

      You can look at these 1.1ton inverter AC that will fit in your budget.

      Since your usage is high (about 1000hrs/yr) and tariff in Kolkata is also high we recommend you to go for high efficiency ACs (Inverter AC or a BEE 5sta AC).
      If you can increase your budget to 33k you can get a good Sharp 1.1 ton inverter AC. Inverter AC would save more than 30% electricity compared to a normal BEE 5star AC.

  • Ajay Hiraskar

    Hi Abhishek – I live in Pune & need to install split A/C’s in my hall which is approx 400 sq. ft on the top floor facing the West & therefore get direct sunlight in the afternoon & early evening thru a window sized 9 ft x 6 ft. Usage will be around 3-4 hours a day for around 6 months a year.

    What is the number & tonnage recommended? Should I look at Inverter A/C’s or Normal Split ones? Should it be 3 star or 5 star rated? Which brands or models do you recommend?

    Ajay

    • Abhishek Jain

      Hi Ajay,

      As per my calculations your room needs 3.5 tons of cooling. Or if you go for inverter AC then 3 tons of inverter AC. This is because the hall is huge. Your usage of AC is not high to you may go for BEE 3 star split ACs. But in that case you will have to go for a 1.5 ton and a 2 ton AC to cool the whole hall. Anything lesser will just provide local cooling (6-7 feet area around the AC). You can look at these BEE 3 star rated ACs:

  • Arvind Kumar

    Hi Team,

    I am looking to buy a split air-conditioner and had a few queries :)

    1. My room size is 10 feet X 14 Feet, on the top most floor with a roofing that’s not RCC nor tiles. (At any point of the day, It’s much hotter than the RCC roofed room located on the same floor) – What tonnage should I buy?

    2. The salesperson at a store said that I need to change the AC gas every 2 years or so. – Is this true, coz I was under the assumption that the gas is recycled and hence the question of refilling gas does not arise.

    3. How do I know if the air-conditioner has copper or aluminium coils?

    Thanks for getting back,
    Arvind.

    • Abhishek Jain

      Hi Arvind,

      Which city are you in? And how many hours will you use the AC per year (we need yearly usage to suggest the right model for electricity savings)? Changing of AC gas is not required every two years. If you go with an AC with anti corrosion coatings (like blue fin) then you would not need that. You can ask the dealer to open and show the indoor and outdoor units of the AC. If it look like one in this image: http://i00.i.aliimg.com/photo/v0/941140728/Economical_Blue_Fin_Condenser.jpg then it is copper coil with blue fin condenser, If it looks like this: http://www.smartclima.com/wp-content/uploads/2013/03/Serpentine-Condenser1.jpg (no copper tube coming out) then it is a aluminium parallel flow condenser or multi channel flow condenser. Please note that PFC or multi channel is energy efficient but just that it is difficult to repair. Also blue fin condenser has copper tubes and aluminium fins coated with blue anti corrosion enamel which prevents it from corrosion.

    • Arvind Kumar

      Thanks Abhishek,

      I live in Bangalore and would probably use the AC for 24 hours a week in summer and then maybe as low as 10 hours a week for another 6 months and 3 months, sparingly use it during the monsoon and peak winter weather conditions.

    Hi BijliBachao Team,
    Need your help for selecting splits for two bedrooms in the 1st (top) floor of my house at Mumbai. Size room no. 1: 12×18 ft Room no. 2: 12×11 ft. from my initial research it looks like capacity of 1.5 ton & 1 ton respectively are enough. My usage will be 7 hrs for night time and 2 hrs for day time for 4 months in a year. Need your recommendation as to what star rating I should go for and the million dollar question which brand? Please suggest some models as well. Also please comment on safety of R32.

    Really appreciate your work here. Thanks a lot in advance for your help.

    • Abhishek Jain

      Hi Leslie,
      According to our calculation your first room (12*18) requires 1.8 tons of cooling during peak summer day time. Since your usage is mostly at night we recommend you to go for 1.5 ton inverter AC it will work relatively well during peak summer day time.
      Your second room (12*11) requires 1.1 tons of cooling during peak summer day time. So we recommend you to go for 1 ton inverter AC.
      Since your usage is high (above 1000hrs/yr) and tariff in Mumbai is also high (Rs10) we recommend you to go for inverter AC only.

      You can look at these 1.5 ton inverter ACs.

      R32 is a hydrocarbon so it is certainly flammable but Daikin (which is the only brand that uses it) has been able to make safe models using R32.

      Hi Abhishek,

      Thank you so much for the detailed reply. Really appreciate your work.

      Have more questions for you.

      1) One of the showroom sales person said that the circuitry in inverters is quiet sensitive to voltage fluctuations and that the main circuit is quiet expensive to replace if damaged. Actually, my location does experience voltage fluctuations. Do you see this as a problem for inverters? Do yo think voltage stabilisers can help, if yes, can you suggest brand, models etc.

      2) With average Rs. 10 /unit cost of electricity, for what kind of usage do you suggest buying 5* and 3*.

      3) What do you feel about the Carrier Superia Plus range of inverters

      4) Sharp website has given EER of 4.41 for AH-XP18PHT, that would make it most efficient in 1.5 tons, is this right or am I missing something here…?

      Thanks again for your help.

      Regards,
      Leslie

    • Abhishek Jain

      Hi Leslie,
      Here are my responses.
      1) The PCBs in inverter ACs are expensive. But you can protect it by using a voltage stabilizer with a good surge protection in it.You can go for V-Guard stabilizers with surge protections.
      2) At Rs10/ unit we recommend people to go for BEE 3star ACs at less than 600hrs/yr usage. BEE 5star ACs at less than 900hrs/yr usage. And inverter ACs for more than 900hrs/yr usage.
      3) Carrier Superia Plus range of inverters are great. If you want you can certainly go for it.
      4) 4.41 EER of the Sharp AH-XP18PHT AC is its peak EER are which is at lowest tonnage of cooling. The average EER of Sharp AH-XP18PHT AC is 3.66. Inverter AC has a range of cooling capacity and power consumption therefore it has a variable EER. It has a lowest value and a highest value of EER. 4.41 is the highest EER value for Sharp AH-XP18PHT AC.

  • Giby

    Hi BijliBachao Team,

    Firstly awesome work here with this website. So much useful information. This is my first post.

    Now back to the topic. After weeks of reading online and hopping around shops, I have concluded few things.

    I need 1 Ton Inverter AC with R410a refrigerant.

    I liked the low GWP of R32 but scared of its flammable properties.

    I have zeroed in on few brands but not able to decide which one to go with as every shop keeper boasts about one brand and play down the rest. Below is the list.

    – Sharp 1.1 Ton with Plasmacluster.

    Very Good online reviews but not sure of the after sales service. I don’t have any issue with the product as I already own a Sharp refrigerator since and it is going well so far. As an Indian we always want to be assure of after sales service.

    – Panasonic with Econavi, + for Bluefin condenser

    Didn’t find much online reviews but I liked the features, again not sure of how good will be the support.

    – Bluestar, with Bluefin condenser

    – Daikin but the shops have R22 models only.

    I live in Chennai.

    Can you please help?

    Thank you,

    Please feel free to add any other brands/ products if they are not in the above list.

    • Abhishek Jain

      HI Giby,
      I hope you have done the right calculations for your room as undersized AC cannot cool properly. Oversized also has problems but as you are going for inverter tech AC all those problems will not come up. Now typically Hitachi, Daikin, Sharp, Samsung, LG have models with higher EER in inverter tech. Daikin does not use R410 and instead it has R32 air conditioners. In terms of durability I feel that Japanese brands (Hitachi, General, Daikin, Sharp, Panasonic, etc) + carrrier + blue star have good reliable models. So considering all the factors (that you are looking for), I think Sharp 1.1 ton inverter AC would be great for you. From the feedback that I have got from people who have purchased Sharp is that the models are really good (with good cooling and features). Their post sales service is a bit patchy at some places but as you already have their refrigerator, you would have already experienced their service. If you are happy with their service then there is no reason to not go for Sharp as their products are quite good.

    • Giby

      Thanks Abhishek

  • Dr Jatindera P Singh

    I am based in Delhi. I need to buy air conditioners for my house. Ist room is about 200 sq feet, 1st floor with one storey build on it. It is east facing and does not receive too much direct sun light. The 2nd room is 167 sq feet, and again is on the first floor with one storey built on it. It does not received any direct sun. My usage would be about 5 hrs in the afternoon and about 6 hres at night.
    I would like to first decide about whether I should go in for a 5 star window ac or a 5 star split or invertor ac. Are 5 star window ac’s as efficient as 5 star split ac’s ? What models would you recommend ?

    • Abhishek Jain

      Hello Dr Singh,

      The 1st room needs about 1.9 tons of cooling in peak summer and the 2nd room needs 1.6 tons of cooling. If you go for fixed speed ACs then a 2 ton AC for 1st room and 1.5 ton AC for 2nd room would be fine. If you go for inverter AC then 1.8 ton inverter AC for 1st room and 1.5 ton inverter AC for 2nd room would be fine.

      BEE star rating for window ACs is 1 level lower than that of split ACs. So a BEE 5 star rated window AC would be equivalent to BEE 4 star rated split AC. Inverter AC is 20-30% more efficient than an AC of same EER (Energy Efficiency Ratio). So if there is a BEE 5 star rated AC of EER 3.51 and an inverter AC of nominal EER of 3.51, then inverter AC will save 20-30% more than the regular AC. With each BEE star rating increase the energy saving increases by 7%.

      Your usage if about 11 hours a day and in Delhi tariffs are high, so I would recommend you to go for inverter ACs. You can look at these:

      1.8 ton inverter ACs:
      Daikin FTKM60PRV16
      LG BS-Q246C8R3
      LG BS-Q246C8A2
      Samsung AR24HV5NBWK
      Daikin FTKP60PRV16
      Daikin FTKV60NRV16

      (Some of these may be marked as 2 ton but their nominal output is 1.8 ton)

      1.5 ton inverter ACs:

      Brand Model EER Ratio (Cooling)
      Samsung AR18HV5DAWK 3.82
      Hitachi RAU019CVEA 3.81
      Hitachi RAU019IVEA 3.81
      Hitachi RAU019AVEA 3.81
      Hitachi RAU019EUEA 3.8
      Daikin FTKM50PRV16 3.8
      Hitachi RAU018IUEA 3.73
      LG BS-Q186C8R6 3.67
      Sharp AH-XP18PHT 3.66
      Sharp AH-XP18PMT 3.66
      Sharp AH-X18PET 3.66
      Sharp AH-XP18MV 3.66
      Hitachi RAU018HVEA 3.61
      Carrier Kurve Inverter (1.5T) 3.57
      Samsung AR18HV5NFWK 3.55
      O General ASGA18JCC 3.51
      Hitachi RAU018HUEA 3.5
      Daikin FTKP50PRV16 3.46

      (The list above has all models with good energy efficiency and listed based on decreasing energy saving potential).

    • J p singh

      Dear Abhishek
      Thanks for the response. Pl let me know what difference does an EER of 3.81 or 3.8 or 3.6 make in practical terms in no. of units of electricity consumed. Which is better – copper or aluminum ac. Which of the models which u suggested are copper. Thanks.
      Dr. J. P. singh

    • Abhishek Jain

      Hi Mr Singh,
      A typical 1.5 ton inverter AC would consume about 0.9 units/hr. An AC of EER 3.8 would be about 6% more efficient than AC of EER 3.6. If the AC of EER 3.6 consumes 0.9 units/hr than the AC of 3.8 EER would consume about 0.86 units/hr.
      There are two types of condensers Tube and Fin type (with copper tube and aluminium fin) and Parallel Flow Condenser Or Multi Channel Flow Condenser. PFC/MCFC are made all out of aluminium. They are highly energy efficient but are not very durable in harsh climates (but can work in regular climates). I have seen PFC/MCFC mostly in Samsung, Lloyd and some other brands that have cheaper AC models. Hitachi, Carrier, MHI, Mitsubishi Electric, Daikin and all have Tube and Fin type condenser.

      Among the models given only Samsung has multi flow condenser the rest have Tube and fin condenser.

    • J p singh

      Would u consider delhi to have a ‘harsh’ climate ? Do hitachi daikin Mitsubishi invertor ac have coated or blue fin technology as mentioned in ur article regarding copper and aluminum pipes etc. can u recommend some Mitsubishi invertor ac in 1.5 and 2 ton with their EER and price if possible

    • Abhishek Jain

      Hello Mr Singh,

      Delhi would not be harsh climate as far as corrosion is concerned. It is more for coastal and humid areas. However if you are close to Yamuna then you certainly would have to look at it. Hitachi, Daikin, Mitsubishi all have coated blue fin technology. You can look at these Mitsubishi Inverter ACs:

      brand model eer_ratio tonnage “eer_ratio_heat
      ” star_rating price
      MITSUBISHI ELECTRIC MSY-GE18VA 3.36 1.5   Inverter Cooling Only 52510
      MITSUBISHI ELECTRIC MSY-GE24VA 3.61 2   Inverter Cooling Only  
      MITSUBISHI HEAVY INDUSTRIES SRK50ZMX-S 3.85 1.5 4.44 Inverter Hot and Cold  
      MITSUBISHI HEAVY INDUSTRIES SRK60ZMX-S 3.65 1.8 4.07 Inverter Hot and Cold  
      MITSUBISHI HEAVY INDUSTRIES SRK52HE-2 3.37 1.5 3.76 Inverter Hot and Cold  
      MITSUBISHI HEAVY INDUSTRIES SRK18YL-S 3.44 1.5   Inverter Cooling Only

      I have added some hot and cold inverter ACs as well because they are really good for delhi both in summers as well as winters.

  • prateek

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

    • Abhishek Jain

      Hi Prateek,

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

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

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

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

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

  • R Jaiswal

    Dear Mr Abhishek,

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

    I wanted to know the followings from you:

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

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

    Rgds,
    R. Jaiswal

    • Abhishek Jain

      Hello Mr Jaiswal,

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

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

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

    • R Jaiswal

      Dear Mr Abhishek,
      Good day and thanx a lot for answering my queries. I’ll go for 1.5 ton Inverter AC – as suggested by you and shortlisted LG: BSA18IMA (?55990) and Hitachi: Kashikoi 300i (?56690). Which one is better to buy and why?
      It would be great if you could mail your reply to my email id as well. Thanking you in anticipation.
      Rgds,
      R. Jaiswal

    • Abhishek Jain

      Hi Mr Jaiswal,
      I would recommend you to go for Hitachi: Kashikoi 300i as it has better EER compared to LG: BSA18IMA. Also Hitachi is a better and more reliable brand compared to LG.

  • Prabhu

    Hi Abishek,

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

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

    • Abhishek Jain

      Hi Prabhu,

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

    • Prabhu

      Hi Abishek,

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

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

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

      Thanks many in advance.

    • Abhishek Jain

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

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

    • Abhishek Jain

      Hi viswanath,

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

  • Karan

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

    • Abhishek Jain

      Hi Karan,

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

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

    • Karan

      Thanks for the info.Love your site.Keep on doing great work that you are doing.

  • harsha

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

    • Abhishek Jain

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

    • harsha

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

    • Abhishek Jain

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

  • Prasad

    Hi Abhishek,

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

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

    • Abhishek Jain

      Hello Mr Prasad,

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

    • Prasad

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

      Regards,
      Prasad

    • Abhishek Jain

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

    • Prasad

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

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

    • Abhishek Jain

      Hello Mr Nair,

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

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

    • Biju Nair

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

    • Abhishek Jain

      Hello Mr Nair,

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

    • Biju Nair

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

    • Abhishek Jain

      Hello Mr Nair,

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

  • VENKATESWARA RAO PASUPULETI

    Dear Abhishek,

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

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

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

    • Abhishek Jain

      Hello Mr VENKATESWARA RAO,

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

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

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

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

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

  • nupur666

    Hi Abhishek,

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

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

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

    Thanks!

    • Abhishek Jain

      Hi Nupur,

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

      BEE 5 star 1.5 ton ACs:

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

      1.5 ton inverter ACs:

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

    HI
    I GOT CALCULATED FROM ENGINEERS REQUIREMENT FOR MY CENTRE(1250 sq fet) IN BASEMENT WITH NO WINDOWES AND ENTRY DOOR FACING EAST IN JAIPUR
    APPROX 8HP IN VRV
    AND 9 TON IN SPLIT AC REQUIRD
    ONLY 3 TON WAITING AREA (cassetee type )as i am planning for FALSE CEILING aND 1.5 TON AC IN LAB -WILL WORK FOR MORE THEN 1500 HRS/YEAR
    rest 2 ac(1.5 ton ) will work for 1000hrs/year
    rest 2 ac(1.5 ton)will work for 600 hrs/year
    NOW TELL ME SHOULD I GO FOR VRV OR NOT
    if not then i am advised for
    inverted ac where usage is more then 1500 hrs then 2ac -one invertor cassete 3ton and one inverter 1.5 ton cassete or split
    remaining two-5 star split and other two where usage less 3 star split ac
    THERE IS DIFFERENCE BETWEEN COST VRV (APROX 5 LAKS) AND NON VRV (4LAKHS)
    so what should i opt
    SECONDLY WHICH BRAND FOR VRV and which brand for non VRV

    Thank you so much
    Dr Sharma

    • Abhishek Jain

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

  • Ritesh

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

    • Abhishek Jain

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

  • Dipak Vyas

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

    Thanks;
    Dipak

    • Abhishek Jain

      Hello Mr Vyas,

      Which city is this for?

    • Dipak

      Hi Abhishek, am in vadodara city, Gujarat

      Thanks, dipak

    • Abhishek Jain

      Hello Mr Vyas,

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

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

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

    • DIpak Vyas

      Abhishek;

      AM planning to go with your suggestion to keep 2 1 TE AC for my Drawing cum Dining Room.
      As shared earlier, the portion connected to dining is stair case goes above and have plan to cover it with insulated glass.
      However, there still need to be an opening of 3.5ft x 6 Ft, either to place Glass door or to keep Open.

      Having glass door is cumbersome and would like to keep this portion open.

      DO you suggest this can still help me with good cooling or do you suspect significant exchange of heat?

      Also this AC may be used for 3-4 Hrs a day, so

      DO you still suggest to have Invertor AC or any other can do? Pl help me with options.

      Thanks and regards;

      Dipak

    • Bijli Bachao Team

      ACs are intended to cool a closed space. If the space is open (heat leaks) then electricity consumption increases. If you cannot keep the space closed then a fixed speed AC would be better than Inverter Tech AC. As it is your usage is less so you can go for BEE 3 star rated AC.

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

    • Abhishek Jain

      Hi,

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

      Daikin FTKM35PRV16 or FTKP35PRV16 (1 ton)
      Hitachi ACE or iClean Inverter AC (1 ton)
      Sharp AH-XP13LV, AH-XP13PHT, AH-XP13PMT, AH-X13PET (1.1 ton)

    • Dharmesh

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

    • Abhishek Jain

      Hello Mr Dharmesh,

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

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

    • Abhishek Jain

      Hi Ujwal,

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

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

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

    • Abhishek Jain

      Hello Mr Sandeep,

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

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

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

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

      1.8 ton inverter AC:
      Daikin FTKM60PRV16
      Daikin FTKP60PRV16

      Or 2 ton inverter AC: Mitsubishi Electric MSY-GE24VA

    • Jothi Ramalingam

      Mr Abishek,

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

    • Abhishek Jain

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

    Dear Abhishek,

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

    Regards,

    Sanjay

    • Abhishek Jain

      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.

  • Joydip Ghoshal

    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

      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.

  • sudhakar

    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

      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.

      Digital Inverter AC AR18HV5NFWK 1.5 TR or Digital Inverter AC (crystal gloss panel) AR18HV5DAWK 1.5 TR. Which is best ?

    • Abhishek Jain

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

    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

      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

  • vasu gaba

    is haier split air conditioner is good to buy

    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

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

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

    • Abhishek Jain

      Which city is this for?

  • jatinder pal singh

    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 .

    • Abhishek Jain

      Voltas says copper tubings, but I am not 100% sure. You can check with the dealer.

  • Priyanshu

    Hi Abhishek
    how is the performance of CROMA Air conditioners…

    • Abhishek Jain

      If you are interested in economy brands, then I would suggest Onida, Lloyd, Haier, Electrolux.

  • Priyanshu

    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

      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

      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

      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

      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.

  • Naman

    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

      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.

  • Ruchi

    Hi thanks for your prompt response. I am ok with local cooling. Can you please give top 3 suggestion for both window and split ac.

    • Abhishek Jain

      You can look at:

      1.5 ton AC:
      Hitachi RAU518HUD
      Godrej GSC 18 FG 6 WNG or GSC 18 FG 6 ONG or GSC 18 FG 6 BNG
      Whirlpool 3D Cool Climate Control PLT V or 3D Cool Elite IV
      or any LG BEE 5 star rated model
      Mitsubishi MS-GK18VA

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

  • ruchi

    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

      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.

  • vikas

    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

      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

      You should go for 2 ton AC.

    • Priyanshu

      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

      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.

  • Umesh Daryanani

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

    harpal singh

    • Abhishek Jain

      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

      Namaste sir,many thanks for your prompt reply,regards

    • harpal

      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

      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.

  • [email protected]

    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

      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

      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

      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).

  • Prabu

    Hi Abhishek,

    Warm Greetings!

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

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

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

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

    Your suggestions and advice would be highly appreciated.

    Cheers!

    Prabu

    • Abhishek Jain

      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

      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

      Hello Mr Prabu,

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