Comparison of various refrigerants (R-410A, R-22, R-32, R-290, R-134A, R-600A) used for Air Conditioners and Refrigerators

By on May 2, 2017

While growing up in the 1990s I used to hear a lot about CFCs (or chlorofluorocarbons) and their involvement in depletion of ozone layer. There were talks that all the refrigerants that cause environmental harm will be phased out. But as the years passed by, the thought of checking if a refrigerator or air conditioner that is being purchased has environmentally friendly refrigerant or not, vanished, as the presumption was that the CFCs have been phased out and we only get environmentally friendly refrigerants these days. But is that true? Or do we really care? In this article, we will look at various refrigerants that are used in air conditioners and refrigerators that are available in Indian market.

What is a refrigerant?

A refrigerant is a fluid that is used in air conditioners and refrigerators, to take heat from the contents of a refrigerator or the room (in the case of ACs) and throw the heat out in the atmosphere. A refrigerant undergoes phase changes from a liquid to gas (on absorbing heat) and back to liquid (when a compressor compresses it). The choice of ideal refrigerant is made based on its favorable thermodynamic properties, non-corrosive nature, and safety (non-toxic and non-flammable). Although many fluids can be used to act as a refrigerant, but in 20th century, CFCs became the most popular refrigerants.

Old and Modern refrigerants

The most common refrigerant in the past was a CFC, most commonly called as Freon. Freon was a brand name for a refrigerant “R-12” by DuPont.  In the 1990s and 2000s, the CFCs were replaced with HCFCs (hydrochlorofluorocarbon) and the most common HCFC is “R-22”. 50-60% of Air Conditioners in India still (in 2016) use HCFCs. However, HCFCs are just marginally better than CFCs as they contain chlorine, which is harmful for the environment. As per Indian Government’s plan, HCFCs will be phased out from India by the year 2030.

To remove chlorine from the refrigerant, manufacturers created another set of refrigerants called HFCs (or Hydro Fluro Carbons). Although they also have the potential for global warming, but still they are better than HCFCs as they do not deplete the ozone layer. The most common HFC used in air conditioners is R-410A. This refrigerant is better than R-22 in terms of “Ozone Depletion” potential and energy efficiency, but it still causes global warming. A few more HFCs that are commonly used are: R-32 in Air Conditioners and R-134A in refrigerators. About 20-30% of the air conditioners in India still (in 2016) use HFCs. R-32 is better than R-410A in terms of global warming potential, but then it is still an HFC. As per latest news, India plans to phase out HFCs as well in next few years, and the timeline for it is still under consideration.

The most environment-friendly refrigerants that are available in Indian market currently are “R-290” and “R-600A”. They are HC or Hydrocarbons, and their chemical names are “Propane” for R-290 and “Iso-Butane” for R-600A. They are completely halogen free, have no ozone depletion potential and are lowest in terms of global warming potential. They also have high-energy efficiency but are highly flammable as they are hydrocarbons. But they are the greenest refrigerants in the market. Manufacturers, who use these refrigerants, claim that they have taken good care in using these refrigerants and the appliances are absolutely safe. In fact, most refrigerators in the Indian market are now on R-600A and there are no reported incidents of any accidents due to the same. So we can comfortably believe that they are safe.

Below is the data for Global Warming Potential of various refrigerants (source):

RefrigerantGlobal Warming PotentialOzone Depletion Potential


If you are someone who cares about energy efficiency and global warming, go for an Air Conditioner with R-290 or a Refrigerator with R-600A. The more you opt for it, the more the manufacturers will start using them in their appliances. Hopefully, with stringent standards and better advancements in technology, we will be able to see better refrigerants in future.

Is it healthy to live in air conditioned room through out the day ?


Actually, I have purchased an a/c with r-22 refrigerant but now it seems that it isn't Eco- friendly.The above the information is really good and very knowledgefull.


Anyone please suggest me which one is good out of these Daikin series of ACs - ATF, DTF, or FTF.
I would like to buy 1.5 Ton 5 star AC with cooling mode only. I prefer to buy an environmental friendly AC despite of cost. In fact, I prefer O General, but it is still using the R410A, which is not an environmental friendly. Please suggest me one.

Abhishek Jain (Mod)

ATF, DTF and FTF are the same series with similar technical specification but different features. ATF and DTF are smart phone operable and have different air filters. FTF is basic model. You can go for any one of them depending on your budget.


Hi Abhishek, my bedroom is 220 sq ft and in summer the temperatures goes to 42-44 degree and in winter goes to 4-6 degree. Suggest me inverter AC with good energy rating as well as features of auto cleaning, auto off timer, copper condenser. I am looking in brand Voltas, Bluestar, Carrier and Hitachi. The max usage in summer will be 3-4 months. Also can the same be used for heating in winter?

Abhishek Jain (Mod)

Hello Mr Brij,

To calculate right tonnage, one needs to evaluate multiple factors. And without knowing them I cannot suggest you the right product. And calculating right tonnage is the most important thing to do before buying an AC. I would suggest that you use the calculator on this page to calculate the right tonnage: https://www.bijlibachao.com/top-ten-appliances/best-air-conditioner-ac-window-split-hitachi-lg-carrier-samsung-electricity-consumption-tonnage-in-india.html

One you have calculate the tonnage, let me know the same along with the budget that you have and I can suggest you some good models. As for heating feature, I would say Voltas has non inverter heating and cooling models, which are not very energy efficient. Hitachi does not have heating models. Blue Star has the best heating and cooling inverter ACs, but I will have to look at your tonnage and budget to say if it will fit in your requirements or not.

Hi abhishek, i bought 1.5 ton 3 star lloyd LS19A3LP-W. My usage is mostly 2 summer months. is this the right buy? I was not knowing this page earlier. Is there anything to worry abt lloyd brand nd its service centr is just 100 mtrs nr my house?

Abhishek Jain (Mod)

Lloyd is a good brand. If your usage is not high then this seems like a good choice.


Hi Abhishek,

I am in dilemma in buying the perfect AC for my bedroom. The room size is 16.5x11.7x10 feet. I want to buy an AC with heating and cooling facility as well as saving electricity and the atmosphere too.

Can you please suggest one for me?

Abhishek Jain (Mod)

Go for Blue Star 5HNHW18PAFU or Daikin FTHP50.


Hi Abhishek,
Will 1.5 Tonnage be sufficient for the room size?

Abhishek Jain (Mod)

Depends on the peak summer temperatures in your city. But most likely yes. Which city are you in?


Hi Abhishek,

Sorry for the late reply. I am from Kolkata, the city with scorching heat and horrifying humidity. I went to check on the Inverter ACs and the salesperson asked about the size of the room where the AC will work on. He told me to go for a 2 ton (at least a 1.8 ton) AC.

Abhishek Jain (Mod)

Hi Jayanta,

2 ton or 1.8 ton is the right calculation for your room. And frankly in Kolkata you do not need hot and cold AC. We usually suggest people to go for hot and cold only if the heating feature will be used for at least couple of month. Or when you use it to replace a room heater which is used for 2 months. There is no place in India where that happens. Even in North India room heater are used only for couple of weeks in a year. It will be better if you go for a cooling only inverter AC.

If you want heating and cooling one then you can look at Blue Star 5HNHW24PAFU (5 star) or Daikin FTHP60SRV16 (4 star) or Blue Star HNHW24CBFU (3 star) or Carrier Superia 365 inverter 2 ton


Hi Abhishek,

Thank you for the details. Please suggest me 2 Ton Inverter AC with 5 star rating (preferably with refrigerant R290).

Abhishek Jain (Mod)

You can look at these:

Mitsubishi Electric MSY-GK24VA
Blue Star 5CNHW24PAFU (Amazon Link: http://amzn.to/2n5WXZR )
Daikin JTKM60
Toshiba RAS-22N3KCV-IN + RAS-22N3ACV-IN
Blue Star 5CNHW24DAFU

Godrej is the only brand that uses R290 and they do not have a 2 ton inverter AC.


Hi Abhishek i am planning to buy mitsubishi DXK37CSS-S6 1.1 Tonn ac for my 110 sq feet Room where my Usage is for 12 Hr per day Dealer told me that it's sufficient and energy efficient too that it will cover 172 st feet as per company specifications. Please express your views and price he offers is 41000 finale all including

Abhishek Jain (Mod)

And BEE 5 star rated inverter AC will be lot more energy efficient.

Abhishek Jain (Mod)

Hi Praful,

Mitsubishi Heavy is a really good brand and their models are certainly very energy efficient. I think the model is really good. However, in a budget of 41K, you can get BEE 5 star rated inverter AC of 1 ton and that too from Blue Star which is a premium Indian brand, check this on Amazon: http://amzn.to/2onV5KU


Hi Abhishek i have bought mitsubishi 1.1 Tonnage ac and now want ac for my 145 sq feet Room ac for that i choose Hitachi rau514hwds 1.2 Tonnage ac please guide me

Abhishek Jain (Mod)

Hi Praful,

You have already chosen a brand and model which are good ones. What more information do you need?


How advantageous it is to have an inverter split ac with autoclean or iclean like hitachi models. Is this a big issue?

Abhishek Jain (Mod)

Cleaning of filters is very important for cooling efficiency as well as energy efficiency (or electricity saving). Unclean filters result in lesser cooling and more electricity consumption. You can clean filters manually as well as shown in this video: ..... but autoclean or iclean does that automatically for you.


I am confused with all brands ac, i saw some videos in which some real peoples suggest to buy Mitsubishi or o'general heavy duty ac which has low maintenance. I need your suggestion here as i want to buy one ac for 2 rooms which has wall between them one big room and one small room, i have a plan to put an exhaust fan in the wall to transfer the cool air to small room by installing the ac in the bigger room. bigger room size is around 15/11 foot approx and smaller room is 11/12 approx.

I want to buy ac in onetime, i want quality for lowest possible electricity bills and low maintenance and low issues with all required features which has to be in it. if possible i need all weather ac for hot and cold climate. i live in Chandigarh. In winter i m using currently 2000watt air blower in both rooms separately. I don't want to hurt ozone layer also, i love earth and i want to save it. So good refrigerant also required.

In clear words i just want all rounder ac with best efficiency, eco friendly and low maintenance and low electricity bills.

Money doesn't matters to me as i never hesitate to spend extra money for a best product.

Abhishek Jain (Mod)

Hi Harsh,

It is not advisable to use one AC for two room. To explain why, let me give you a anlogy to help you understand. Imagine you have a tank of water which is not completely full but is getting filled by incoming rain from top. You want to maintain the water level of the tank, so you put a tap at the bottom of the tank so that water is taken out from it as it gets filled from top. You choose a tap that can take out water at a rate such that the water level is maintained.

Now you have another tank for which you need to maintain the water level. And you join the two tanks using a pipe as you already have a tap on the 1st tank to take out water. Does the tap have to be of same size or bigger to take out more water??

Similarly the tank here is your room which is full of heat. You want to maintain the temperature and you put an AC (equivalent to a tap) to take out the heat from the room. The heat is coming in from outside (through the walls, windows, etc). Now you add another room. In that case you need to take a huge AC (taking care of the size of both the rooms). Because there is heat in both the rooms that need to be removed.

The size of AC will also depend on how much heat are you getting from the walls. Just like the size of tap you put on the tank will depend on the amount of rain you are getting that is filling the tank. If your walls directly face the sun, then they will get very hot and the AC size needed would be more. If the walls are surrounded by other rooms (and also has room on top), then the heat coming in the room will be much less. So you need smaller sized AC.

Just by applying thumb rule (which is not always correct as you can see above), a 150 sq ft room in Chandigarh would need 1.5 ton AC. Your 1st room is 165 sq ft so by thumb rule, cooling need is 1.65 ton and the 2nd room is 132 sq ft, so cooling requirement is 1.32 ton. It will be more if walls/ceiling get heated up.

Now to cool both the rooms you need 1.65+1.32 = 2.97 or almost 3 tons of cooling. Usually you would not get a 3 ton AC in the market. So I think it will be better to go for individual 1.5 ton inverter ACs for both the rooms. Inverter ACs are variable tonnage, so they can fit to a room's need. A 1.5 ton inverter AC can vary its tonnage from 0.5 to 1.7 ton. So it can cover your room with need of 1.65 ton as well as room that has need of 1.32 tons cooling.

Mitsubishi Heavy and General both are premium brand with great build quality. They are highly durable and the response for both of them is generally positive. Between the two I think Mitsubishi Heavy has more energy efficient (or electricity saving) models. I think their SRK50ZMX-S model would be a great choice if you are looking for heating and cooling. It also has R410A which is a good refrigerant.


Thanks for your suggestion, Now i made my mind to put only one ac in bigger room first. So you suggested Mitsubishi SRK50ZMX-S model but i also need more features if possible like dehumidifier, auto clean, sleep mode, auto restart, air purifier. Brand is not limited to Mitsubishi or o'general only, i want best ac from best brand, with best features , highly energy efficient and best cooling and heating function & low maintenance.

Please suggest me more ac for this purpose. ( From any best Brand ).

Abhishek Jain (Mod)

Hi Harsh,

Dehumidification is part of every AC. When the air gets cool, the humidity in the air condenses and converts to water. And that is why every AC needs a pipe outside to drain water. So whatever AC you buy, dehumidification will be part of it. Also sleep mode and auto restart is part of almost every AC these days. Auto clean and air purifier is not there in every one.

If you need hot and cold energy efficient AC with good air purifier, then I would suggest Blue Star 5HNHW18PAFU. It is a very good AC with 7 different kind of air filters. Its energy efficiency is also high. It has blow clean functionality for filter cleaning (not really auto clean but quite close).


Thanks God. I am lucky for being an owner of r290 Refrigerants ac like godrej inverter ac...... Thanks godrej for saving our earth and also help us for cooling..... Keep it up. U r the best ac maker in india..........


If r32 is a global warming potential.. why its flammable?

Abhishek Jain (Mod)

R32 is Difluoromethane which is flammable. It has less global warming potential.


From one of your article "Air conditioner selection: understand Tonnage, EER, COP and Star Rating" i had done some math for a standard room size of 10*10*10 in few different locations. There is an average difference of around 1400/- per year among BEE 5 Star Non inverter Vs BEE 5 Star Inverter, and the price difference is around 14000 for this two models. How should one look at this this like regarding savings it would take like 10yrs to gain back what we invested today otherwise are the inverter ac's are good for us and nature. I am confused with such things can you please provide some clarity over these.

And one more thing need your opinion over Reconnect brand AC's they are providing at very low prices with R410A gas, copper foil etc. At a a minimum difference of about 4k and free installations are been offered to.

Abhishek Jain (Mod)

A lot depends on your usage and tariffs. For a 10x10x10 room mostly one would need a 1 ton AC (in a place like mumbai even a 0.75 ton would do). Every star rating is a range of energy efficiency. So a BEE 5 star rated non inverter AC starts with EER of 3.5, but the most efficient BEE 5 star rated non inverter AC would have EER of 3.95. Similarly BEE 5 star inverter AC would start with ISEER of 4.51, but then it goes as high as 5.8.

Now the numbers in the calculator are Median (or most likely representation) of the star rating. If we look at real numbers for 1600 hrs of usage, here are they:

1) BEE 5 star non inverter with EER of 3.51 - Annual Electricity Consumption = 782 units for 1600 hrs
2) BEE 5 star non inverter with EER of 3.95 - Annual Electricity Consumption = 651 units for 1600 hrs
3) BEE 5 star inverter with EER of 4.51 - Annual Electricity Consumption = 601 units for 1600 hrs
4) BEE 5 star inverter with EER of 5.8 - Annual Electricity Consumption = 483 units for 1600 hrs

Now assuming the usage is 1600 hrs (it can be more as well for some people). The difference between the least efficient BEE 5 star non inverter and most efficient BEE 5 star inverter is about 300 units in a year. Most efficient one costs Rs 55000 and the other one would cost Rs 28000. The cost difference is Rs 27000. If you are in place like Mumbai where tariff is Rs 10-12, 300 units translate to annual savings of Rs 3000. This means 9 yrs payback. If your usage is more than 1600 hrs a year, then the payback can be much lesser as well.

But then the model with highest efficiency also comes with inbuilt air purifiers, extra features, etc. In general the most efficient models are from premium brands, with extra features. Like if you go to buy a premium car, it will be loaded with features. So all those costs also get built in.

The numbers in the calculator are brand independent, just plain numbers based on data collection (efficiency numbers and price data). It was made because people usually ask this question to us: "Should I go for inverter AC? Which Star rating should I go for?" .... now costs and payback usually can be calculated when you know the models you are comparing. Without that, it is difficult to make any comparison. For e.g you will find that Samsung has BEE 5 star rated models that are highly efficient and quite cheap. The economics completely varies over there. But then you can also get Reconnect AC which is quite cheap which again changes the economics. You will find that brands like Hyundai, Mitashi, Sansui and Onida have very cheap inverter ACs as well. So one has to look at real models and do economic check. Also before that one should decide on the brand which they want to go for. Only then can the economics be validated properly. The data in the calculator is just to give some high level idea.

As for Reconnect, I would say that many retailers have got into the market by importing products from China and re-branding them. They may not have technical expertise to design an AC, but then it is not that Chinese people make bad ACs. But then I would not rank them high on durability. But it is not that they would not work. It is like if you are in market to buy a smart phone, Micromax also works great. But is it comparable to Samsungs and Apples in terms of technology, NO, but does it work, YES. If you have basic requirement, it does work. The easiest thing for any company these days is to import products from China, rebrand them and sell them. But sooner or later Chinese themselves will enter the market and start selling their own products. It has started happening in Phone with entry of LeEco, Xiaomi, etc. Earlier indian companies used to import their products and rebrand them and sell them. Later they realized that they themselves can enter on their own. Even in ACs, companies like TCL have started getting into the market on their own. If you are looking for a cheap product, then Reconnect will work. I would not say that it will be bad or will not work. It will work, but then it will not be as long lasting as premium brands.



Abhishek Jain (Mod)

You can go for Hitachi RAW318KUD Kaze eco plus.


I am planning to purchase llyod hot & cold split ac model LS18NHC 1.5 ton capacity, pls advice

Abhishek Jain (Mod)

Hi Anup,

I would not recommend this model as it is very low on energy efficiency both for cooling and heating. It's cooling capacity is 5400 watts and power consumption cooling is 1910 watts. So the EER is 5400/1910 = 2.82. This will be almost equal to 1 star rating. If you want to go for hot and cold, better go for an AC with inverter technology. Non inverter models in hot and cold are not electricity saving at all.



Abhishek Jain (Mod)

Both are BEE 3 star rated window ACs. They are very low in energy efficiency and will have high electricity consumption.


But based upon low usage in Dehradun which model is best among these two. Hitachi RAW318KUD and hitachi RAW318KXDAI.

Abhishek Jain (Mod)

From electricity consumption point of view, both are same. RAW318KXDAI has greener refrigerant (R410A), so I would say RAW318KXDAI would be better.


Hi Abhishek,

Please suggest 1.5 ton split ac for my lobby. is Inverter ac is good option for this...

Abhishek Jain (Mod)

Hi Mohit,

In general Inverter AC is not good if the space is open and large and the AC is undersized. Inverter ACs are good only when they are rightsized or oversized. You can put multiple inverter ACs if the space is large. But then total tonnage should be right.


What's your suggestion 9n normal split Ac.


Hi Abhishek,

Based on the below calculation, I have calculated the EER for 2.5 ton O'general ac.

Formula: EER = cooling capacity (watts)/ power consumption cooling (watts).
OGeneral ASGA30FUTA EER = 8180/ 2340 = 3.495

This is a 5 star AC, how do I calculate the energy efficiency by the EER. Also how do I get to know that Star Rating is of this year and not of last year or earlier.

Abhishek Jain (Mod)

Hi Mohit,

Energy efficiency is defined as output/input and EER is exactly the same (output watts)/(input watts). So EER is energy efficiency. And 3.49 rounds up to 3.5 and any AC with EER of 3.5 and above is BEE 5 star (as per current rating). So this is a BEE 5 star rated AC, although it just barely qualifies for 5 star as the EER is on the border.


Any other choice in 2.5 ton which has good cooling along with more EER.

Abhishek Jain (Mod)

I would suggest that you look at Mitsubishi Heavy Industries SRK25CSS-S6 (2.2 Ton AC). It has long air flow and should be good for your use. You can check the specs over here: http://www.iaplgroup.com/srk20css-s6_srk25css-s6.php


I was not aware that some other company or tie-up has rights to sell Mitsubishi heavy duty in India, so asked for it. How do I buy it as there is not link or dealers mentioned to buy it, also the customer care is keep on waiting and disconnects automatically.

Abhishek Jain (Mod)

Please make sure that your city has a service center. Check this link: http://www.iaplgroup.com/customercare.php

Abhishek Jain (Mod)

Drop a note on their Contact Us form and they will contact you. At least that's what I did when I talked to them about a year and half back. And I was connected to the dealer in Mumbai within a day.


Can you please share the link of the mitsubishi website where they have shown the details of this ac, as I am unable to locate the dealer for this in my area and if you have than the customer care number.

Abhishek Jain (Mod)

I had already shared it in my previous message. Sharing it again: http://www.iaplgroup.com/srk20css-s6_srk25css-s6.php


Will this Mitsubishi cool equally as 2.5 ton of ogeneral...

Abhishek Jain (Mod)

It will.


Hi Abhishek,

There are 2 models in 2.2 ton, which one I should go for, as per the dealer it just the name difference else everything is the same. Also, which stabiliser I should go for the Mitsubishi 2.2 ton.

Abhishek Jain (Mod)

They have two models: SRK25CSS-S6 and DXK 50 CS - S6 ... The first one is BEE 5 star rated and the 2nd one is BEE 3 star rated. So I would suggest going for SRK25CSS-S6. Choice of stabilizer depends on how low your voltage dips to. If the fluctuations are rare then you can go for Solatek AC Guard (Amazon Link: https://amzn.to/2kaBLRH , Flipkart Link: http://fkrt.it/GVtiXTuuuN ).


They told me that another model is DSK74CSS with same configuration. Can you please suggest the different between these 2 models.

Abhishek Jain (Mod)

Can't say anything. The data is not there on their website: http://www.iaplgroup.com/dxk53css-s6_dxk74css-s6.php


Dealer told me to take v-guard VGB 500 which is costing INR 4500/- so can you please suggest if there is any difference between these.

Abhishek Jain (Mod)

You can go for VGuard VGB 500 as well if dealer is confident it can support 2.2 ton. Usually VGuard markets 500 series for up to 2 ton ACs. But if dealer knows that it can work, then it should work.



Dealer has suggested not to go for RAV518HUD as there are many issues coming in this model. Can you please suggest which other model I should go for and are you aware of such issues with this model.
How about RAW518KUDZ1?

Abhishek Jain (Mod)

RAV518HUD has EER of 3.5 and that of RAW518KUDZ1 is 3.35. That is about 5% difference in electricity consumption. So the difference is not a whole lot.


Is there any major difference between the functions of both the models.

Also, the SRK25CSS is copper or aluminum?

Abhishek Jain (Mod)

SRK25CSS is copper.

Based on Hitachi Website,

RAV518HUD has these extra features:

Twin Air Flow For Uniform Cooling
Kaimin Function
Super Silent
Auto Climate Technology
Super Cool Function

And RAW518KUDZ1 has these extra features:

Auto Climate Technology
20 Innovative Feature
Powerful Mode
Dry Mode
Auto Restart
Auto Fan Speed

These other than common features.


How about the cooling capacity? Is it equally good as compared to rav518hud model.

Abhishek Jain (Mod)

Just slightly less. RAV518HUD is 1.52 ton whereas RAW518KUDZ1 is 1.5.

Abhishek Jain (Mod)

I would say normal split AC would be better in that case.


how is GRANDEUR-SA123GDR onida Ac
usage will be limited to summer months only getting a good price of 22600

Abhishek Jain (Mod)

Onida is a good brand. They make 100% copper ACs. Their energy efficiency numbers are good in general. You can certainly go for it.


Thanks for the reply,
I came across panasonic KC-123 KY3 one ton ac
The price is nearly around 29000/-
The usp is the inbuilt air purifier
Whats your take on that
Is it worth to buy with a price diff. Of nearly 5.5 thousand

Abhishek Jain (Mod)

Hi Parag,

A good air purfier costs more than 5.5 thousand if that is what you are concerned about. So in that sense it is certainly worth. And Panasonic is a better brand as well.


Sir, I am looking for a 1 ton 5star window AC in Delhi, Hauz Khas. What do you suggest me?

I had posted this question a day ago too but i can't see it on the forum :(

Abhishek Jain (Mod)

You can look at any of these:

Whirlpool MAGICOOL COPR 5S (1.2 T) (Flipkart Link: http://fkrt.it/O5xJw!NNNN ) ... although it is marked as 1.2 ton, its actual tonnage is 1.09

Hitachi RAW511KUD (Amazon Link: http://amzn.to/2qFetqy , Flipkart Link: http://fkrt.it/O58Lt!NNNN )

Whirlpool MAGICOOL COPR 5S (1 T) (Flipkart Link: http://fkrt.it/a0HmsTuuuN )

Blue Star 5W12GA (Amazon Link: http://amzn.to/2qPz1sO , Flipkart Link: http://fkrt.it/OhVhw!NNNN )



I mind told me purchase ac with 5 star or inverter technology.
& also good for environmental Eco-frendlly.
what is the best GAS for AC's
please provide me list of Gas with difference between all gas,
so i can understand essely

Abhishek Jain (Mod)

Hello Mr Hasmukh,

We have written about all the gases and their difference in the post above. R290 is the greenest gas that is available in Indian market. Godrej is the only brand that is currently using R290.


Hitachi which model is good RAW318KUD Kaze eco plus. Or RAW318KUD Kaze plus.

Abhishek Jain (Mod)

Kaze Plus has better features. But RAW518KUDZ1 is a much better model.


Which AC model is best in Hitachi Kaze plus or Kaze eco plus. Hitachi RAW318KUD or Hitachi RAW318KUD air.

Abhishek Jain (Mod)

Hitachi Kaze Plus is a better model. It is more energy efficient. And has better features. I hope you are looking at BEE 5 star model of Kaze Plus.


How about Voltas 1.5 ton hot and cold split ac. Which model is good and whats your opinion about this.

Abhishek Jain (Mod)

Voltas hot and cold models are not with inverter technology. Their energy efficiency levels are quite low. I would not recommend them.


What is the comparison with other split ac having star rating vs voltas hot and cold. Which star rating it can match, if I only use the cold option...

Abhishek Jain (Mod)

Voltas Hot and Cold ACs have cooling EER of 3.13 which would be equal to BEE 3 star split AC and even in that it would be on the lower side (as BEE 3 star range is from 3.1 to 3.3). The Hot and Cold Inverter AC from Daikin (FTHP) and those from Blue Star are equal to BEE 3 and 5 star inverter AC (and are better than BEE 5 star non inverter ACs) with ISEER of above 4.


hello abhishek....wonderful article ..i am planning to buy panasonic 1.5 ton 5 star model no. sc18sky5. but i want to know the refrigerant gas used in the model as iam unable to find it in the website .... and the showroom dealer also told me abt lg dual inverter ac model number JSQ18SUXD as this has copper condensor and has r410a refrigerant.... which one do u suggest?

Abhishek Jain (Mod)

Hi Krishna,

We also do not have information on the refrigerant gas in sc18sky5. The panasonic model is quite feature rich, but I would recommend LG JS-Q18SUXD from energy saving and comfort perspective. Panasonic model has good filters and air purification. But LG model is not too bad in it and then being inverter AC it will give lot of energy saving and will maintain temperature more consistently.

Hello abhishek. Can you tell me whether bluestar 3hw24fbtu is a good air conditioner and what refrigerant it uses? If there's​ any alternative, please let me know.

Abhishek Jain (Mod)

This is a BEE 3 star rated 2 ton AC. It's EER is 3.16 which is on the lower side. Blue Star as a brand is a very good brand and makes great ACs. FBTU series uses R32 refrigerant. However, I cannot say if it will be good for you or not without knowing the requirements of your room and your usage hours/year.

It is important to do tonnage calculation before buying. To give you analogy: suppose you need to take 4 people around the city, you would not buy a truck for the same, you would buy a car that would fit in 4 people. Agreed you can fit 4 people in a truck as well, but then you are spending a lot to buy a truck and then truck will also consume more fuel. Also even if you buy a fuel efficient truck, it still will consume more electricity because it is after all a truck and you need a small hatchback to fit in 4 people!

In you case you are asking about a big truck (2 ton AC) and that too one that is not fuel efficient (BEE 3 star non inverter which is lowest in efficiency in market).

Now I do not know what you need (your room's requirement) and how much will you use it. So I cannot say if this AC will begood for you or not. As a consumer you should know what is the right requirement, your usage, your budget and then decide accordingly. Without all this information it will be like shooting in dark.

I will give you another analogy. If someone comes and asks you which is the best phone.... you would say iPhone7 ..... but then you do not know what will the person use it for. If the use is just for making and receiving calls, sending/receiving sms or whatsapp, then you do not need to spend that much. Even a 5K 4G phone can be good for that. And on top of that yo do not even know the budget that person has .... then you cannot suggest a better model that fits into a person's requirement.


Hi Abhishek a ac dealer in my city told me that the Flipkart and other online site sell outdated and defective product even he also done the same online is it true?

Abhishek Jain (Mod)

Hi Praful,

That is not correct. The ecommerce companies have a very strict policy regarding complaints of sellers and if there are multiple complaints the sellers get delisted. So they cannot do that. The most important thing is to buy from a seller having good seller rating. For each product they have multiple sellers.


Thank you Abhishek and plz suggest me best 1.5 tonne ac in low budget and energy efficient My area in summer goies upto 52 degree Celsius I can afford upto 2000 rs per month in a electric bill

Abhishek Jain (Mod)

Hello Praful,

At Bijli Bachao, we suggest this strategy: First find out the right tonnage that you need for you room, because undersized AC may not cool well, and in case of non inverter AC, oversized AC can significantly increase electricity bills. In inverter ACs, slight oversizing is fine. You can use the calculator on this page to get the right tonnage: http://bijlibachao.com/top-ten-appliances/best-air-conditioner-ac-window-split-hitachi-lg-carrier-samsung-electricity-consumption-tonnage-in-india.html

After finding the right tonnage, you have to look at your usage of AC in hrs/year. And your budget. Because your usage determines if you need high efficiency AC or not. Secondly we try to suggest the most efficient AC based on a person's requirement (tonnage requirement) and the budget.

Let me know the right tonnage (as per the calculator) and your budget and I can suggest you some models accordingly.


Hi Abhishek my room is 140 sq ft and my budget is 35k max and use per day 10 hr/day I afford 2000 rs extra in d bill

Abhishek Jain (Mod)

You can look at any of these BEE 5 star rated non inverter ACs:

Lloyd LS19A5LK

Onida SA185GDR (Flipkart Link: http://fkrt.it/12Mkv!NNNN )

Lloyd LS19A5CX (Flipkart Link: http://fkrt.it/1b1YN!NNNN )

Voltas 185 PY

Whirlpool MAGICOOL ROYAL 5S (1.5 T) (Amazon Link: http://amzn.to/2nQM409 , Flipkart Link: http://fkrt.it/RbqDR!NNNN )

These are energy efficient and would be good for your usage.


Hi Abhishek thank you so much for your valuable suggestions and time. I decided to go wid lloyd ls19a5lk but there is no seller available online for the particular model.

Abhishek Jain (Mod)

lloyd ls19a5lk is the best model from lloyd. But unfortunately it is not available online. The next best are these:

Lloyd LS19A5SN (Amazon Link: http://amzn.to/2pTRqXU )
Lloyd LS19A5CX (Flipkart Link: http://fkrt.it/GIOKATuuuN )


I want to buy one window ac 1.5 ton 3 star. Which will be better option Carrier Estreela, Carrier Marvel, Hitachi Kaze Plus, LG CP3 or Blue Star 3W18LB/GA

Abhishek Jain (Mod)

Hi Sanwar,

BEE 3 star window ACs are very low on energy efficiency. They are equivalent to BEE 2 star rated split ACs. The theme of this website being Bijli Bachao, I would not be comfortable in recommending any of the BEE 3 star rated window ACs.


Is Panasonic a good brand ? I am planning to buy Panasonic KC18SKY3ME for 30000. It's 1.5 ton split a.c. is the reliable. Star rating is not an issue for me.

Abhishek Jain (Mod)

Hi Aman,

Panasonic is a good brand and quite reliable. If you are just asking for feedback on brand then I would say it is good. As for the choice of model, it depends on your room's requirement, your usage, your electricity tariff, etc. So I cannot comment if it is good or not. But Panasonic is a reliable brand.


Hi Abhishek,

I'm planning to buy 2 Inverter AC under 1 and 1.5 ton capacity in Gurgaon, Haryana (calculated tonnage as per Tonnage calculator present already) & shortlisted below mentioned models:

1. For 1 Ton - Daikin JTKM35 (applicable room is on Ground Floor with no direct sunlight)
2. For 1.5 Ton - Daikin JTKM50, MSY-GE15VA (although its 1.25 Ton) & MSY-GK18VA (applicable room is on Second Floor with direct sunlight from 3 sides) - as per Mitsubishi site, their models are R410A based which I've heard is not efficient one under higher temperature conditions, just for reference Temperature can be above 50C in my locality in summers.

Already have one Daikin Inverter model installed on ground floor since last 3 years which doesn't have good history (PCB failure, despite Stabilizer installed with it and minimum direct sunlight+damp conditions).

Please suggest the best possible models considering my requirement and area conditions as mentioned above.

You may add any other model if you feel its superior to these, any worthy suggestion will be highly appreciated

Abhishek Jain (Mod)

Hi Ankush,

Daikin JTKM series has operating temperature of 46. So it may not be good for you in summers. You may look at Hitachi Kashikoi 5400 series (if hitachi has good service in your area) or Blue Star 5CNHW18PAFU or DAFU series. Mitsubishi MSY-GK18VA is also a very good model.

By the way what was the reason for PCB failure with your previous AC?


Thanks for your prompt reply Abhishek, really appreciate this!!
Daikin technician didn't provided the exact reason (citing manufacturing reasons for Inverter series since all other generic reasons like - Voltage fluctuation and Damp conditions were not applicable in my case) and just replaced it since it was under warranty.
Coming back to our discussion, I've made up my mind for 1.5 Ton - MSY-GK18VA (Inverter).
Though, still in dilemma over 1 Ton between MSY-GE13VA & HITACHI KASHIKOI 5400i - RAU512CWEA.
Also please suggest best possible 1.5 ton Windows ACs for one First floor room (second floor above this room and one Sun facing side) in Gurgaon region too - I was looking at OGeneral (AXGT18FHTA) and Hitachi (RAV518HUD), please add any other model/brand if you feel so.

Abhishek Jain (Mod)

Hi Ankush,

Hitachi Kashikoi 5400i series is more energy efficient. Also it is much more feature rich with lots of sensors to optimize performance. But if you are going for one Mitsubishi model, it would be better to go for two of them so that you can get them serviced together. As for 1.5 ton window ACs I think Hitachi RAV518HUD would be a better choice.

Yogender Dabas

daikin atc50srv 3 star is better or hitachi same 3 star split ac. Cost of both is almost same. Also blue star 5 star split inoverall.

Abhishek Jain (Mod)

Blue Star 5 star split would be better.


Is this model TV18SKY3 of Panasonic have R410A
and let us inform if you have any idea about this model.

Abhishek Jain (Mod)

As per panasonic website, it does have R410A.


Hi Abhishek,
Please suggest me 3 star inverter ac with heating and cooling from following brands..
Voltas, Daikin and Blue Star

Abhishek Jain (Mod)

Hi Abhinav,

Voltas does not have inverter AC with heating and cooling. The models that they have are normal ACs with heating and cooling, and I would not recommend them as they have very low energy efficiency.

Daikin models are not yet rated on BEE star rating because it is not mandatory. But Daikin FTHP series is quite good.

In Blue Star there are BEE 3 star rated inverter ACs with hot and cold feature: RBFU series & CBFU series. In 1.5 ton RBFU is a better series.


Hi, Abhishek,

Please Guide Should I buy Panasonic Model


Abhishek Jain (Mod)

Does not look like an Indian model. Where are you getting it from?

Abhishek Jain (Mod)

However, In general panasonic is a good brand and this model on Philippines site looks quite interesting.


Please reply fast


Abhishek hi, please guide whether I should buy Voltas 183 SY and 183LY 1.5 TON 3 STAR, if I need 100% copper unit up
Is R 22 gas is going to be banned by govt in how much time

Abhishek Jain (Mod)

R22 complete phase out is by 2030 (check this news: http://www.livemint.com/Politics/btLbJnVEEu8N0dOsqnHbZJ/India-launches-second-stage-of-HCFCs-phaseout-plan.html )

Of the two models you have listed, Voltas 183 LY (Amazon Link: http://amzn.to/2qhlNW8 , Flipkart Link: http://fkrt.it/g75J~TuuuN ) is a better model with more cooling capacity and better energy efficiency.


Hello, my house is near a nala, and my usage of ac wont be much. It will be only in summer. I recently went to shop and the salesman suggested me panasonic kc18sky3me which has bluefin condensor,100 percent copper,and rust free metal sheet. I am confused because i dont usually see people buying panasonic. Also can u suggest me which other models i can go for.


this ac is not copper, it is 100% alloy


How much price are you paying for this a.c ? I am also planning to buy same model ? Even I am confused about Panasonic..

Abhishek Jain (Mod)

Hi Lubna,

Panasonic and Blue Star have models with copper condenser and good corrosion protection (blue fin). And Panasonic is certainly a good brand. What is your budget for the AC? And what tonnage are you looking for? We have a calculator to get the right tonnage on this page: https://www.bijlibachao.com/top-ten-appliances/best-air-conditioner-ac-window-split-hitachi-lg-carrier-samsung-electricity-consumption-tonnage-in-india.html

I would suggest that you use that.


Hi Abhishek,

I am looking forward to buying 1 Ton 3 Start Fixed Speed Split AC. Could you please provide your expert advise on following models ?
1. LLoyd LS13A3LR
2. Blue Start 3HW12JCFU


Abhishek Jain (Mod)

Lloyd LS13A3LR is more energy efficient but has lesser cooling capacity. Blue Start 3HW12JCFU has more cooling capacity so it would cool faster, but then it is less efficient. If cooling is your main concern then go for Blue Star 3HW12JCFU.


Hi Abhishek,

This is an amazing gesture, sharing your knowledge with everyone! Thanks for that.

As for my query/request,

I live in coastal Chennai (ECR). There are frequent power issues(surges,low voltages, you name it) too.
My room is 150sqft
Minimum usage is anywhere between 19-24 hours, as I work from home. Ground floor and no direct sun light, tightly sealed.

1) Hunting for an inverter 1.5 5 star A/C for the past few days. I've narrowed it down to Blue star and Daikin.
2) Since I'm already tight on budget, taking the EMI route to buy, Which in turn has again narrowed it down to only Bluestar as the shop I am planning to buy, Do not have the 5 star inverter model in Daikin.
3) This left me with the choice of going with Blue Star.. PAFU and DAFU. Again, Bluestar people are saying only DAFU 5 star 1.5 inverter model is available and PAFU is out of stock.

Will it be alright to get an inverter model, Main reason being the usage, To save. Or is it a big no for people near sea to get inverter models. Distance between the sea water and my place is approximately 1Km-1.5Km
If not inverter, Kindly suggest other models which will be the most energy efficient ones.
Thanks, again!

Abhishek Jain (Mod)

Hi Arun,

Based on the feedback that we have from people living in coastal region, the challenge is that the PCB of inverter AC fails due to corrosion when there are winds coming from sea. The PCB is in the outdoor unit. For your usage Inverter AC would have been ideal, but then failure can be an issue. I think you can go for BEE 5 star rated normal AC as well. You can look at these:

Blue Star 5HW18SBTU or 5HW18ZBRTU or 5HW18ZBWTU

Hitachi RAU518AVD (Amazon Link: http://amzn.to/2nbzNy4 , Flipkart Link: http://fkrt.it/h9Nl1TuuuN )

Hitachi RAU518HWDD (Amazon Link: http://amzn.to/2mL4JK1 , Flipkart Link: http://fkrt.it/RE!cs!NNNN )

Daikin DTF50 (Amazon Link: http://amzn.to/2nbC6Bl , Flipkart Link: http://fkrt.it/hlU!DTuuuN ) or ATF50 or FTF50.

Based on the feedback the failure has happened for people at around 3 years or so. If you can achieve savings in that period then Inverter AC may also be a good choice considering your usage.


Great, thank you. Will keep updating how it goes :)


Hi Abhishek I am also looking for best split ac 1 ton models with Rs:35000 budget. I have lot of confusion in choosing an good model and guide which is better R32 or R410 with full copper or Aluminium.
I have chosen some brands

Abhishek Jain (Mod)

If your environment is not corrosive, then both copper and aluminium can work well. But if your environment is corrosive then go for copper. R32 and R410 both are good but R32 is slightly better. But R32 is available only in Daikin and Blue Star. You can look at these models:

If you want inverter AC then this would be better:

Blue Star 3CNHW12CAFU (Amazon Link: http://amzn.to/2oxKzmN )
Voltas 123V EY (Flipkart Link: http://fkrt.it/ngSsj!NNNN )

If you want non inverter then you can look at these:

Lloyd LS13A5LK (Flipkart Link: http://fkrt.it/3rIXu!NNNN )

Lloyd LS13A5LX (Flipkart Link: http://fkrt.it/3r~pu!NNNN )

Onida SA125CHE

Hi Abhishek, as per last discussion I choose LG GS -q18 auxa copper model because there are a nala near my home but as u said PCB of inverter Ac also sensitive for corrosive environment so I am again confused between inverter and non inverter Ac and more thing as godrez 1.5 ton 5 star copper model gsc 18 usz 5 wpr is r 22 model and godrez site said as eco friendly r 22 so plz give your valuable advise should I go for it or not

Abhishek Jain (Mod)

If you have nala close by, you may avoid inverter AC. You can go for non inverter. Also R22 is not eco friendly. You can look at Blue Star 5 star rated models that are highly energy efficient and use R32.

Jitendra Pawani

Hi Abhishek after lots of searching and valuable advise by u I choose godrez fixed split ac 5 star and one 3 star model ffzh 3 rwph prised at 35k and 30k respectively , as one Ac will use in guest room hardly for 2-3 month in year is it good choose plz give your views on it

Abhishek Jain (Mod)

You can certainly go for a 3 star AC for guest room where usage would be less. Godrej is a good brand. They are the only ones using R290 which is the greenest refrigerant in the market. So I think it is a good choice.

Jitendra Pawani

This model using r 410, can u plz give your advise about this model ffzh 3 rwph is it right decision

Abhishek Jain (Mod)

It is a BEE 3 star rated model with EER of 3.2. The decision depends on your usage. If usage is low and tariff is low, it can be a good choice. But if usage/tariff is high then it may not be right choice.


Hi Abhishek,

I am looking for 2 AC (one window of 1.5 Ton and one split of 2.5 ton), which brand (till now I am thinking Ogeneral or Voltas) I should go for and also keeping the zero Ozone Depletion Potential and least Global Warming Potential. I don't want to destroy the climate just for my comfort. Your early response would certainly help me in deciding and finalising the products.

Abhishek Jain (Mod)

Hi Mohit,

What is your budget for these ACs?


30-35 k for window and 70- 80 k for split. I also need good cooling as I live on the 2nd floor with direct sun hit my floor, so it remain quite hot all the time. I am fine with 3 - 5 star.

Abhishek Jain (Mod)

Hi Mohit,

In Window ACs you can look at these:

Hitachi RAV518HUD (Amazon Link: http://amzn.to/2negUKO , Flipkart Link: http://fkrt.it/AF7GETuuuN )

Hitachi RAT518HUD (Amazon Link: http://amzn.to/2mMYF3P , Flipkart Link: http://fkrt.it/AFS7ETuuuN )

Hitachi RAW518KUDZ1 (Amazon Link: http://amzn.to/2ocvFS0 , Flipkart Link: http://fkrt.it/1mVbV!NNNN )

Whirlpool MAGICOOL COPR 5S (1.5 T) (Amazon Link: http://amzn.to/2oNmclY , Flipkart Link: http://fkrt.it/1I!kV!NNNN )

Panasonic CW-KC1816YA (Amazon Link: http://amzn.to/2ph4t6k )

Voltas 185 ZYA (Flipkart Link: http://fkrt.it/1IXl3!NNNN )

Blue Star 5W18GA (Amazon Link: http://amzn.to/2ob8JQW , Flipkart Link: http://fkrt.it/RqJcM!NNNN )

In 2.5 ton you can go for O General ASGA30FUTA .

Now the O General 2.5 ton AC is BEE 5 star rated and has R410A which is a greener refrigerant. But then it is hard to find energy efficient window AC that has R410A.

Firstly manufacturers have stopped making new window ACs and they still selling their old models for past many years. In fact BEE star rating of Window ACs is 1 level lower than Split ACs. Then R410A is there only in BEE 3 or 2 star rated window ACs which are equivalent to BEE 2 or 1 star rated split AC. So either you harm environment by going for bad refrigerant or by more electricity consumption.


Thx for your prompt response Abhishek.

So we don't have any window or split AC in R290 or R600A. I am completely fine with Brand as long as they serve the purpose and of good quality.

Abhishek Jain (Mod)

R600A is mostly used in Refrigerators. R290 is currently only available in some of Godrej Split AC units (mostly BEE 5 star rated models).


Can you please provide the models no for Godrej. Also how about Ogeneral for Window ac as well...does that uses R410A. Also whats the difference between inverter ac and normal ac and which one is better

Abhishek Jain (Mod)

Hi Mohit,

OGeneral has a Window AC model that does use R410A, but then it is not very energy efficient. Your electricity bills will be higher. Inverter ACs are certainly better and to understand the difference, you may check this page on this website: https://www.bijlibachao.com/air-conditioners/what-is-inverter-technology-air-conditioner-and-how-it-is-different-from-bee-5-star.html

These models of Godrej use R290:

Godrej GSC 18 FG 8 MOG (Amazon Link: http://amzn.to/2ouI3yC , Flipkart Link: http://fkrt.it/M52NZ!NNNN )

Godrej GSC 18 FG 6 ROG

Godrej GSC 18 FG 6 BOG (Amazon Link: http://amzn.to/2ouyKyD , Flipkart link: http://fkrt.it/jtR7bTuuuN )

Inverter ACs are certainly far better in terms of energy efficiency. You can also get models with R32 or R410A which are much better than R22. But R290 is best and Godrej also has inverter ACs in R290:

Godrej GSC 18 GIA 5 AWOG

Godrej GSC 18 GIG 5 DGOG (Amazon Link: http://amzn.to/2ouxifT , Flipkart Link: http://fkrt.it/jtU7bTuuuN )


Models you have provided of Godrej are Split AC's and I am looking for 1.5 ton window AC and 2.5 split ac. I know I am bothering you quite much but want to make the right choice before buying. Hope you understand.

Abhishek Jain (Mod)

Window ACs do not use R290. Even in Godrej. And as I mentioned, R410A is available only in low efficiency window AC models.


So if I need to buy Window AC, I need to have R 22 only..O GENERAL: WINDOW AC- 1.5- 3STAR- AXGT18FHTA how about this one... and which window ac has R410a with 4- 5 star.

Abhishek Jain (Mod)

If you want to buy Window AC you have two choices: 1) Go for R410A model that is less energy efficient or 2) Go for R22 which is more energy efficient. Either way there is damage to environment. Either by using bad refrigerant or by burning more coal.

These days split ACs have better choices. Manufacturers have not improved window ACs for past 4-5 years.


What is your choice in R22 in Window AC with 1.5 ton and also good in cooling with energy efficient. I initially plan to take Voltas with 4 or 5 star, as you suggested that the rating is one level lower than Split.
On the other hand, your choice for Split AC of 2.5 ton with 5 star rating and with environment friendly, on this my choice was OGeneral as I need good cooling.

Abhishek Jain (Mod)

Hi Mohit,

For 2.5 ton I recommended O General ASGA30FUTA. The problem was with window AC. And in that I would say go for any of these:

Hitachi RAV518HUD (Amazon Link: http://amzn.to/2negUKO , Flipkart Link: http://fkrt.it/AF7GETuuuN )

Hitachi RAT518HUD (Amazon Link: http://amzn.to/2mMYF3P , Flipkart Link: http://fkrt.it/AFS7ETuuuN )

Hitachi RAW518KUDZ1 (Amazon Link: http://amzn.to/2ocvFS0 , Flipkart Link: http://fkrt.it/1mVbV!NNNN )

Whirlpool MAGICOOL COPR 5S (1.5 T) (Amazon Link: http://amzn.to/2oNmclY , Flipkart Link: http://fkrt.it/1I!kV!NNNN )


How about Voltas in Window AC? Is it not a good choice or any major difference with the options you have mentioned. Do we also have an inverter ac option in window as well.

Abhishek Jain (Mod)

Hi Mohit,

I already mentioned this earlier that Inverter option is NOT there in Window ACs.

In Voltas you can look at Voltas 185 ZYA (Flipkart Link: http://fkrt.it/1IXl3!NNNN )


Apologies Abhishek. As this is a long conversation, I forgot that you mentioned that no inverter ac option in Window ac.
Again coming back to the same point of difference between Voltas and Hitachi ac? if there is any major difference, I can go for Hitachi.

Abhishek Jain (Mod)

Hi Mohit,

Hitachi has more energy efficient options and that is why I recommended Hitachi. There is no other major difference. You may go for Voltas as well.


Thx Abhishek.

As Godrej has R290 in split ac, do they have 2.5 tom available as I am not able to find it on the website. I can think of buying one 2.5 (1.5 ton + 1 ton) from godrej if in case I am able to save the environment from making more venerable.

Abhishek Jain (Mod)

They do not have 2.5. They have 1.5 and 1. You can even go for their R290 inverter ACs for being much better to the environment. But please note, I would not recommend these ACs if you live in corrosive environment. There is no supplier in India that supplies copper pipes that can handle R290. And thus Godrej has to use aluminium for this. And in corrosive environment aluminium condenser can fail and even inverter PCB can fail. SO let me know what you want and I can recommend accordingly.

If the environment is not corrosive then you can easily go for Godrej R290 models.


I live in Faridabad and don't think the environment is corrosive. I do see major problem of dampness in the weather as most of the houses has dampness on some or the other walls...
At the moment Godraj is also giving 10 Year compressor warranty & 5 Year condenser warranty, so this will cover most of the problems, in case occurs.
Also suggest best ac for 2.5 ton as well, in case I am not able to get the fitting done for 2 ac cos of space and other constraints.

Abhishek Jain (Mod)

You can look at these 1 ton ACs:

Godrej GSC 12 FG 8 MOG (Amazon Link: http://amzn.to/2oBwN2H , Flipkart Link: http://fkrt.it/dIKYFTuuuN )

Godrej GSC 12 FG 6 BNG or GSC 12 FG 6 ROG

In 1.5 ton you can look at this:

Godrej GSC 18 FG 8 MOG (Amazon Link: http://amzn.to/2oPMZcC , Flipkart Link: http://fkrt.it/43Pb8TuuuN )

Godrej GSC 18 FG 6 BOG (Amazon Link: http://amzn.to/2pp3BKc )

In 2.5 ton Ogeneral ASGA30FUTA would be a good choice. But I think Daikin 2.2 ton inverter AC would be a better choice (or the best choice for the room). You can look at Daikin FTKP71 4 star inverter AC. It will be really good with R32 (which is next best after R290).


I am looking for my lobby which has one main entry to house and 4 other entry to rooms. Also it has open kitchen as well, so would 2,2 ton suffice the purpose? Also this OGeneral is not inverter AC?

What is this Cooling only means...."Inverter, R-32, FTKP Series (Cooling Only)" mentioned on Dainik Website

Abhishek Jain (Mod)

If the area is open then I would not suggest inverter AC. In that case you can go for the General Non inverter AC. Open area will lead to compressor running all the time.

"Cooling Only" means that the AC just cools. There are hot and cold models also available that can heat the room in winters.


So I should now go for OGeneral for my lobby for 2.5 ton ASGA30FUTA model, is this 5 star rated and can you please also share the link of Amazon or any other selling the above model.

For Window I should go for Hitachi single motor or twin motor, what is your take? All of these are 5 star rated and do I really need to have a 5 star rated ac for my room as it will mostly run in the night only. Also, does 3 star has more cooling than 5 star ac, few people said this to me.

Please provide your opinion.

Abhishek Jain (Mod)

Hi Mohit,

If you search for this model on Google: https://www.google.co.in/search?q=General+ASGA30FUTA it is available on Croma and TataCliq. It is not available on Amazon or Flipkart.

As for cooling, it is not dependent on star rating. It is dependent on Cooling Capacity of the AC. Higher the cooling capacity faster would be the cooling. So a 2 ton AC would cool faster than 1.5 ton just because it has more cooling capacity. The ton values that you see in market is marketing tonnage. The real tonnage depends on cooling capacity. And 1 ton = 3504 watts cooling capacity. You will find several 1 ton ACs in market with cooling capacity less than that. And you will also find some models having cooling capacity more than that as well.

A 5 star rated AC consumes less electricity and if the cooling capacity is the same then it will be a better choice. Choice of single motor and twin motor does not make a whole lot of difference.


Hi abishek, Article about eco friendly refrigerants are so useful ..
Is there any AC products available in india with R 290 refrigerant.

Abhishek Jain (Mod)

Godrej has models in NXW series that runs on R290.

Abhishek Jain (Mod)

It is a great model and Blue Star is a great brand. You can certainly go for it.

Hi abishek,

How about the 1.5t daikin 3s ETC50s

Abhishek Jain (Mod)

Daikin is a good brand and ETC is a good series.


Thanks for your reply. Shall I go for it? Because I didn't find the model in any other online shopping.

Abhishek Jain (Mod)

Not all models are available online. And Daikin usually does not like selling online. But the model is good. You will have to contact local Daikin dealer to get the same.


Thank you Mr. Abhishek.

Abhishek Jain (Mod)

Great! Thanks a lot for the feedback. It will certainly help others as well.


Hi Abishek,

Hello Abhishek, I from chennai. I am planning to buy a 1 ton 5 star AC for my bedroom. I'm planning to buy R-410A refrigerant models, My budget is 25K-34K. Kindly suggest the better one. Also, if there are other better models, and recommend those as well!

Hi Balaji,

Are you close to the beach? I mean does your room get direct winds from the sea? Ia masking this because if your environment is corrosive then I can recommend models accordingly.


Hi Abhishek,

My home some far from beach. In my room have one window that one park facing view, Park full of trees. Always my room getting some cool.

Please suggest.

Hi Balaji,

Among 1 ton inverter ACs, these would be good:

Blue Star 3CNHW12CAFU (Amazon Link: http://amzn.to/2oxKzmN ) ... best choice
LG JS-Q12BPXA (Flipkart Link: http://fkrt.it/SSbGYTuuuN )
Voltas 123V EY (Flipkart Link: http://fkrt.it/mmSF5!NNNN )

In non inverter, you can look at these:

Daikin ATF35 (Flipkart Link: http://fkrt.it/qaHwv!NNNN )

Daikin DTF35 (Amazon Link: http://amzn.to/2nlJN8I , Flipkart Link: http://fkrt.it/qa3gP!NNNN )

Lloyd LS13A5LK (Flipkart Link: http://fkrt.it/3rIXu!NNNN )

Lloyd LS13A5LX (Flipkart Link: http://fkrt.it/3r~pu!NNNN )

Onida SA125CHE

Onida SA125PRL

Onida SA125SGS

Panasonic CS-KC12RKY-1 (Flipkart Link: http://fkrt.it/tFWEa!NNNN )

Panasonic CS-SC12RKY (Amazon Link: http://amzn.to/2nlJr1O , Flipkart Link: http://fkrt.it/DIhRaTuuuN )


Can u plz tell me which brand is preferable in below list.
Lloyd, videocon, Electrolux, godrej, vestar, reconnect.
Plz suggest me 1.5 ton 3 star ac copper In budget 25 to 30 k. If possible.
And plz arrange above all brand according to u. as per ur knowledge and experience, recommend First, second, third, fourth, fifth,sixth serials wise. per quality durability and performance wise

Abhishek Jain (Mod)

Difficult to rate the brands, but I think Godrej, Lloyd and Electrolux are good brands. Videocon would be next. By the way you can get these copper models with BEE 5 star ratings in your budget:

Videocon VSD55.WV (Amazon Link: http://amzn.to/2orOTjs , Flipkart Link: http://fkrt.it/z!P~GTuuuN )
Mitashi MiSAC155v05 (Amazon Link: http://amzn.to/2oL3j1R )
Micromax ACS18ED5AS01WHI (Amazon Link: http://amzn.to/2oNP4Yo , Flipkart Link: http://fkrt.it/7TOh5!NNNN )

Otherwise these two BEE 3 star rated models would be good:

Lloyd LS19A3GR (Amazon Link: http://amzn.to/2mwkYL2 , Flipkart Link: http://fkrt.it/PKcDGTuuuN )
Lloyd LS19AA3 (Flipkart Link: http://fkrt.it/~nQLW!NNNN )


Thank u very much sir.

Godrej should first option. They used most eco friendly refrigerant like r290... After all godrej is an Indian brand and most promising brand


Hi Abhishek,
I am looking for a 2 TON 3 or 5 star AC for my drawing room. I reside in Mumbai near creek and do not intend to go for a AC with aluminimum coil nor with a inverter. Moreover my budget is anywhere between 35 to 38K. A friend of mine suggested a Onida AC, Model Onida Silk SA243GDR or Onida Grandeur SA243SLK. My usage will not be more than 2/4 hours during summers. Can you please advise or suggest if i should go with this brand? If not, can you please suggest some other models in my budget with copper coil?



Abhishek Jain (Mod)

Difficult to get a 5 star 2 ton AC in your budget. I think Onida would be a good brand if you can get the AC in your budget. You may also look at these:

Mitashi MiSAC203v01 (Amazon Link: http://amzn.to/2owG2gL , Flipkart Link: http://fkrt.it/FjU8qTuuuN )
Videocon VSG63.WE (Amazon Link: http://amzn.to/2osPQJt )
Videocon VSH63.WE

But Onida would be a better brand.


HI Abhishek,

Is 1 ton ac sufficient for 120 sqft room. we are planning to buy eco friendly and energy efficient Ac Can you please suggest us which model will not cause more damage to environment. we use it for 7 to 8 hrs in a day.

Abhishek Jain (Mod)

Hi Maddy,

Tonnage calculation depends on city (as some cities are hot and some not), location of the room (sunlight on walls or not), etc. I would suggest that you use the calculator on this page to do the right calculation: https://www.bijlibachao.com/top-ten-appliances/best-air-conditioner-ac-window-split-hitachi-lg-carrier-samsung-electricity-consumption-tonnage-in-india.html

Once you are done with tonnage calculation, let me know the tonnage and your budget and I can suggest you some efficient ACs.


Hi Abhishek,

Thanks for the reply .. this is what is given when i calculated.

Size of Air Conditioner that you need:
1 Ton (For cooling requirement of 1.1 Ton)

My budget would be up to 40 k. Please suggest if we should buy copper one as it requires less maintainance than alum..

and voltage fluctuations are also there at our place. please suggest even which stabilizer to keep.
Along with ac even if its inverter AC . I heard from many that inverter ac doesnt require stabilizer. But still to be on safer side.

Abhishek Jain (Mod)

These will be the best ACs in your budget:

Blue Star BI-5CNHW12PAFU (Amazon Link: http://amzn.to/2owj7C9 ) ... this is the best choice.

LG BSA12MAYD (Flipkart Link: http://fkrt.it/GEy80TuuuN )

Blue Star 3CNHW12TAFU

Daikin FTKP35

Hitachi RSG312EAEA

Blue Star 3CNHW12CAFU (Amazon Link: http://amzn.to/2oxKzmN )


Choice of voltage stabilizer depends on how low your voltage goes. You can check the list of voltage stabilizers on this page: https://www.bijlibachao.com/appliances/voltage-stabilizers-buying-guide-best-tv-ac-fridge-home-guide-india.html
