Electricity Saving Tips For Homes And Offices

Understand What is ISEER and Star Labeling of Inverter Air Conditioners in India

By on April 22, 2016

A few years back when Inverter ACs were introduced in Indian markets, there was a lot of skepticism about their success in Indian conditions. Although they are quite successful and popular internationally, these ACs did have to go through the tests of Indian consumers. Despite some negative rumors by a section of the market, Inverter ACs have come out with flying colors and have become popular in India. One thing that everyone knows (and many have observed) is that Inverter ACs save “HUGE” amount of electricity. But one question has been there in everyone’s mind: Why is there no BEE star rating for Inverter ACs as available for fixed speed ACs? In the year 2015, BEE did provide answer to the question by starting a Star Rating labeling system for Inverter Air Conditioners. With this post, we will try to answer few questions that people have regarding the new Star Rating for Inverter Air Conditioners.

Why Did Inverter ACs Not Have Star Rating Earlier?

Although purpose of any air conditioner is to cool the space, the way cooling happens in fixed speed ACs is different from the way it happens in Inverter ACs. The technology is a bit different. Fixed Speed ACs have fixed cooling capacity (or tonnage) and fixed input wattage, Inverter ACs have varying cooling capacity and input wattage. The definition of efficiency for a fixed speed AC was quite simple:

EER (or COP) = Output Wattage (or cooling capacity) ÷ Input Wattage.

(EER Stands for Energy Efficiency Ratio & COP stands for Coefficient of Performance)

By calculating EER/COP of fixed speed ACs and defining fixed ranges, BEE was able to divide all the fixed speed models in the market in 5 groups of different star ratings. But this works well when there is fixed output wattage and fixed input wattage. But defining the same for Inverter AC was very difficult as both the input and output wattages vary.

What Will Be The Method To Define Star Rating Now?

World over the method of defining energy efficiency of air conditioners is not EER (Energy Efficiency Ratio), but it is SEER (or Seasonal Energy Efficiency Ratio). The basic theory behind SEER is that the temperature does not remain the same round the year. As there is seasonal variation of temperatures, there is variation in the amount of cooling required. Amount of energy (or electricity) required by an air conditioner to cool a room to 25 degrees (or any other standard temperature) is different when outside temperature is 30 degrees in comparison to when the temperature is 40 degrees. Also the usage (in hours per day) would vary as per the seasons.

SEER calculation thus involves defining annual temperature profile and usage patterns. SEER standards have to be different for different countries as every country has a different climate profile. And thus BEE has defined Indian SEER or ISEER in short. Let’s look at the various terminologies used as part of the definition:

  1. Cooling Seasonal Energy Consumption (CSEC) – Total annual amount of energy (electricity) consumed by the equipment when it is operated for cooling in active mode.
  2. Cooling Seasonal Total Load (CSTL) – Total annual amount of heat that is removed from the indoor air when the equipment is operated for cooling in active mode.
  3. Indian Seasonal Energy Efficiency Ratio (ISEER) – Ratio of the total annual amount of heat that the equipment can remove from the indoor air when operated for cooling in active mode to the total annual amount of energy consumed by the equipment during the same period.

To calculate the total annual electricity consumption the assumption used is that the Air Conditioner will be used for 1600 hrs through the year. Annual temperature profile used is based on weather profile for 54 cities across India. Below is the temperature distribution used:


The ISEER thus calculated will be used to provide star ratings to various models of air conditioners. Below are the defined ranges of ISEER for various star ratings:


What Information Will You Get From Manufacturers?

A lot of what is mentioned above is technical jargon. For an average consumer the most important thing to know is to understand the information provided by the manufacturers. Here are the things that will be available from the manufacturers:

  1. Rated Cooling Capacity (100% Load): This is the marketing tonnage or marketing cooling capacity. Inverter Air Conditioners have variable cooling capacity and a 1 ton inverter AC may vary its tonnage from 0.2 ton to 1.2 ton. But they are marketed as 1 ton inverter AC. Rated Cooling capacity for a 1 ton inverter AC would be 1 ton. As per BEE standards there is a tolerance of ± 5% for this value.
  2. Rated Cooling Capacity (50% Load): BEE has asked manufacturers to provide power consumption at 50% capacity. This is not the minimum cooling capacity, but the 50% of the total capacity. In case of 1 ton AC it would be 0.5 ton. But this does not mean that it cannot go below 0.5 ton.
  3. Maximum Cooling Capacity: This is the maximum cooling capacity. As in the example above of 1 ton, it would be 1.2 ton.
  4. Rated Power Input (100 % load): This is power consumption in watts when the AC runs at 100% load or at the marketing tonnage.
  5. Half Power Input (50 % load): This is power consumption in watts when the AC runs at 50% load or at the marketing tonnage.
  6. Maximum Power Input: This is power consumption in watts when the AC runs at the maximum tonnage that the Air Conditioner can achieve.
  7. Cooling Seasonal Energy Consumption (in kWh): This is the annual power consumption as measured per BEE standards mentioned above. Please note, that this number is for 1600 hrs and actual number for you will depend on your usage and temperature of your city when you use the AC.
  8. ISEER: This is the ratio of total heat removed and total energy consumed. This is the ideal number to compare two ACs as your usage of AC may vary and thus the electricity consumption may not be the same as the number mentioned in Cooling Seasonal Energy Consumption.

How Does Star Rating Of Inverter ACs Compare With That Of Fixed Speed ACs?

Comparing the Star Ratings of ACs across segments (window, split and Inverter) has been the biggest source of confusion for most consumers. Unfortunately the standards that have been defined do not help remove the same. The concept of ISEER can be used for fixed speed ACs as well, but from what we know as of now, it will not be used. The rating standards of fixed speed ACs will remain the same based on EER.

However from what we have seen, even a BEE 2 or 3 star rated inverter AC would be equivalent or better than BEE 5 star rated split AC of fixed speed type. And any inverter AC would be much better than any window AC.

Has BEE Started Rating New Inverter AC Models?

The new standards are voluntary till the end of 2017. Which means, manufacturers can sell AC models with or without star rating till end of 2017. As star ratings for ACs are quite popular amongst the masses, many manufacturers will try to get their models certified by BEE, but it is also possible that you may get models that are not rated. It will be beneficial for consumers if they start insisting on star rating and demanding manufacturers to sell only star rated ACs.

When Will BEE Make It Mandatory For All Inverter AC Models To Be Star Rated?

From the year 2018 onwards, all models of inverter ACs will have to be star rated. Manufacturers will not be able to sell non-star rated inverter ACs.


Star Rating labels for Inverter ACs is a welcome move by BEE. Inverter ACs have raised the bar for energy efficiency of air conditioners in India and labelling will further improve the efficiency. The future looks bright and soon air Conditioners will not be a big strain on electricity bills.

Dear sir
I have another room which contains 480 square feet.it is situated in first floor. There is no room above. If I fix 2 ton inverter ac is it suitable to cool the room. The calculator says 5 ton.

Abhishek Jain (Mod)

Hi Prateep,

DO not put undersized inverter AC as it will consume a lot of electricity. Better put BEE 5 star fixed speed AC for the same. Also it will not cool the whole room. It will just cool the area close to the AC.


Dear sir
In this calculation I got 1.3 tonnge for fit my room. Then I go for 1 ton or 1.5 ton inverter ac plz suggest me as one salesman said 1 ton 5 star inverter ac is equivalent to 1.2 ton. I decide purchase hitachi or daikin company ac 5 star inverter ac. So plz suggest which company is best for me. I am living in orissa.

Abhishek Jain (Mod)

Hi Prateep,

1 ton inverter AC can extend to 1.2 ton but not beyond that. Also inverter ACs consume more electricity when they run at higher capacity and less when they run at lower capacity. If you can go for 1.5 ton inverter AC, then that would be the best. However, if your usage is mostly at night then you can go for 1 ton inverter AC as well (because heat load is less at night). Hitachi and Daikin both have the most energy efficient BEE 5 star rated inverter ACs. Daikin has features like air purification, etc. Whereas Hitachi models have lot of high end sensors for performance optimization. If you want air purification then go for Daikin, else if you want performance optimization, then go for Hitachi.

Prateep Kumar panda

Dear sir
I want to buy a 1 ton inverter ac with 5 star rating. My room size is 154 Sq. Ft. Which is present in ground floor and also above a room is present. The 1 ton ac is suitable or not in this room.


Hello sir..
My room size is 144 sq feet..
And i want to purchase a new ac.
I m confusing between invert or non invertor..
Which is best. For long life.
And I have selected 2 ac
If non invertor then mitshubishi 1.5 ton heavy duty or o general 1.5 ton 5 star..

If invertor then o general asga 18jcc 1.5 ton
Which is the best plz reply me..
My usage is 10 hours at night countinusely

Abhishek Jain (Mod)

Hi Harminder,

I think o general asga 18jcc 1.5 ton inverter AC would be a better choice. It will be energy efficient and would be able to cool the room better.


Thanks Abhishek, my usage would be approx. 2 Tons as calculated. The Mitsubishi is 1.9 Ton inverter but the cost is only 2000 extra from Hitachi 1.8 T non inverter. Hence looked exciting. needed your guidance. I also read your comment regarding the Inverter not being undersized. Would that hold true for 1.9 ton versus a 2 Ton as well or that would be OK. Also is it true that inverter AC might have maintenance issues and may have a shorter life span as compared to a non inverter AC

Abhishek Jain (Mod)

Hi Mohit,

1.5 ton inverter Ac would be undersized for your room. 1.9 ton will not be undersized. In fact 1.9 ton inverter AC can extend to 2.1 ton. So it is perfectly fine for your room. And in fact Mitsubishi inverter AC would be the best choice.

Inverter ACs have PCB in outdoor units that are prone to failure. PCB usually get damaged due to two reasons: 1) Power Surges 2) Corrosion. As for power surges, there is protection available. You can either use a surge protector or voltage stabilizer with thermal overload protection. Or to go for an AC that can handle big voltage range (Samsung and LG have models that can work between 90V and 450V). But then preventing any metal from corrosion is difficult. However, corrosion only happens in corrosive environment (close to sea, lake, river, nalla or chemical factory).

If voltage is a problem then you can purchase a surge protector. But if you live in corrosive environment then it would be better to avoid inverter AC.


Hi, Abhishek, I need to buy a AC for one of the bedrooms (200 sqft) which has direct sunlight from the west side glazing. This is the most used room so I am looking for a 5 star Non inverter or would you suggest an Inverter AC. I was looking at Mitsubishi GN22VF (1.9T INVERTER) or a Hitachi 1.8 T Zunoh 5200f. Would you suggest something else please. Thanks in advance.

Abhishek Jain (Mod)

Hi Mohit,

First and foremost the most important thing to look for before buying an AC is to calculate the right tonnage. Right tonnage depends on city, room’s location (if it gets direct sunlight on walls/ceiling or not), size of the room and number of people in the room, etc. Usually we assume 4 people in a room to do some calculations. But other parameters are required to be known to calculate the right size. A city like mumbai needs less cooling because temperatures do not go too high. But a city like Delhi needs more cooling because it is too hot in summers. Similarly a room on top floor getting direct sunlight on the roof will need more cooling as compared to a room on lower floors. So I would suggest that you use the calculator on this page to calculate the right tonnage: https://www.bijlibachao.com/top-ten-appliances/best-air-conditioner-ac-window-split-hitachi-lg-carrier-samsung-electricity-consumption-tonnage-in-india.html

Secondly the choice of inverter and non inverter depends on your usage and tariff. If the usage is high then it is better to go for high efficiency models and that is where inverter technology comes in. If the usage is low, then non inverter is also fine. And you have to look at annual usage in hrs and not just daily usage. The calculator will also show you the running costs of various types of ACs, so you can evaluate accordingly.

Once you decide on the right tonnage and budget, then I can suggest accordingly. Model wise both the models that you have selected are good. Mitsubishi Inverter AC is a fantastic choice but then a lot depends on what you need.


Hey Abhishek, I see you personally taking time to respond to questions, really appreciate this. Like many I am stuck in the crossroads of choosing an inverter AC. I am looking for three infact.

Could you please recommend some brands/models? I was planning on going for 5 star models, would that be overdoing it or should I stick to just 3 stars? My usage in bedrooms would be for around 8/12 hours and hall would be probably be 8/10 hours tops.

I have a hall that measures upto 370 square feet, hence a two ton AC would be the minimum requirement from what Ive read, what brand do you recommend?

Secondly, for both my bedrooms, they measure about 150/160 square feet each. I think 1 ton should suffice or maybe a max of 1.5, what do you think?

Abhishek Jain (Mod)

Hi Shreyas,

The choice of tonnage depends on a few factors 1) Size of room 2) City that you live in 3) Location of the room if it gets direct sunlight on walls/windows/roof then the load increases 4) Number of people in the room. Usually for home purpose we assume 3-4 people in the room, but then other things are required to do the right calculation. I would suggest that you use the calculator on this page to do the right calculation: https://www.bijlibachao.com/air-conditioners/what-is-inverter-technology-air-conditioner-and-how-it-is-different-from-bee-5-star.html

Also higher star ratings mean more electricity savings, but then you invest more money for higher star ratings. If you are only concerned about electricity saving then BEE 5 star rated model is the best. But if you are looking at what would be more reasonable, then you certainly need to look at your Annual usage of AC (it is not possible to comment on the choice with daily usage). When you use the calculator, you will see approximate costs of buying various star rated ACs and also approx cost of electricity based on your city tariff.

Finally I would not suggest you to undersize an inverter AC. If your hall is big and requires more cooling, it will be better to go for non inverter AC as undersized inverter AC will always keep running at peak capacity and at peak capacity they are not very energy efficient. So we generally suggest people not to undersize inverter AC.


I am looking for a 1.5Ton inverter AC with budget of upto Rs42-45K. Could you suggest the best fit Brand/models based on the below requirement;
- 3/4 star rating (as usage would be for 8-10hrs mostly in night)
- non-corrosive
- Prompt After sales service (Stay in Thane-Mumbai)

Abhishek Jain (Mod)

Hi Vinayak,

You can look at any of these:

Hitachi RSH318EAEA (Amazon Link: http://amzn.to/2oDyR7E )
Blue Star 3CNHW18TAFU
LG JS-Q18AUXA (Amazon Link: http://amzn.to/2rpKteZ )
LG JS-Q18SUXD (Amazon Link: http://amzn.to/2oMG2Le )
Panasonic PS18SKY
Blue Star 3CNHW18NAFU

These are all copper condenser models with high ISEER. Hitachi, Panasonic and Blue Star will have corrosion protection as well.


AR12MV5HEWK 8 Pole vs JTKM 35 CAN YOU COMPARE ADVANTAGES AND DISADVANTAGES and suggest a better value for money AC


or suggest any other better AC, like O general , Voltas , LG,Samsung , only criteria is Energy efficiency , best performance and reliability .

Abhishek Jain (Mod)

What is your budget for this AC?


My max amount is 45k, but looking for a value for money option.

Abhishek Jain (Mod)

The LG models that I have mentioned would be most value for money for you.


Around 40 k - 45 k . Budget is not my concern my concern is best value for money . I hope at least in a year or two we can take back the initial investment difference .

Abhishek Jain (Mod)

Inverter AC will not payback in 1-2 year. But then a lot depends on the brand you are choosing as well. Brands like Hitachi, Daikin, etc that are premium brands will be expensive even for a BEE 5 star rated non inverter AC. While LG and Samsung BEE 3 star rated inverter ACs will be quite cheap (cheaper than BEE 5 star non inverter from premium brands) and decent value for money. You can look at these LG BEE 3 star rated inverter ACs:

LG JS-Q18ATXD (Amazon Link: http://amzn.to/2plxzkK )

LG JS-Q18AFXD (Amazon Link: http://amzn.to/2oA2VBg ) similar model with different design

LG JS-Q18CPXD (Amazon Link: http://amzn.to/2oA7Ban ) ... this is an Amazon only product and I doubt you will get this in market.

LG JS-Q18NPXA (Amazon Link: http://amzn.to/2oA6Nm5 )

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

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

These are all highly energy efficient as well as quite value for money. The AU, SU and TU series have copper condenser.


And does buying an inverter 5 star Ac make sense when it is 6000 to 10000 rupees costlier than a non inverter 5 star AC .


Got a clear idea of the new ISEER value, but how does this value help a customer in staying in Chennai where , round the year average temp in day time is about 33 degrees max and 23 degrees min . And a exhaustive research showed me that most of the Ac s are still showing EER values or many are not showing any values at all . And almost all the Ac manufacturers claim max rated current of less than 5 A for the same cooling capacity as my ten year old AC which has a max rated current of 5.7 A. I am unable to judge how to buy an AC with the specifications given by each manufacturer . Suggest me a energy efficient AC 1 ton capacity for a 100 Sq.ft room open to sun on west side and have a false ceiling roof . I selected the JTKM 35 from daikin but am atracted by samsung new 8 pole motor AR12MV5HEWK model and the price .

Abhishek Jain (Mod)

BEE did their best to come with some value that can help you identify which AC is energy efficient and which is not. India is such a big country and has different climate at different places. Coming up with one forumla that can handle all is impossible. The number may not be exact based on your location, but it is still the best bet for India. It at least gives you idea as to which AC is more efficient. No one can tell exact electricity consumption as it will vary based on 100s of factors. But it does point you to something better.

In case of inverter ACs what you read as "Max" is truly "Max". It does not mean that it will run at that amount of current. Inverter ACs have variable speed compressor which will change its speed depending on the need of the room and thus its current drawn will also change. And 5A is "max".

Now to buy an AC, 1st thing is to calculate the right tonnage (which actually depends on city, room location and room size). For that I would suggest that you use the calculator 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

The next thing is to choose the right star rating based on your usage (you can always go for higher star rating if you really want to save electricity, not just for saving money, but for the environment, etc). The calculator also gives you approximate amount that you will have to pay in electricity (again this is based on the BEE data and so it is an approximation, no one can give you exact amount) for various star ratings. This will help you identify if you should go for highly energy efficient AC or not.

The last thing to look at is brand and obviously your budget and what exactly fits in your budget. You may also have to look at the right kind of material and technology for your AC. As not everything works great in all environment. And specially in corrosive environment (which is close to sea, lake, river, nalla or any water body or chemical factory), it is better to avoid aluminium condensers and also unfortunately you also need to avoid inverter ACs as PCBs are prone to failure in corrosive environment. Now if you are in Chennai and you are close to the beach (within a couple of KMs) then I would suggest you to avoid inverter AC. And would suggest you to go for an AC with copper condenser with solid corrosion protection.

You may not need a BEE 5 star rated inverter AC if your usage is not high. But if you want to go for it, I would not try to stop you as it certainly saves more electricity. But for ROI, you need to check your annual usage. I would suggest you use the calculator on this site first.


First of all thanks for so much of ur painstaking efforts to provide us all great insight about energy conservation.
Anyways i have been looking for 1.5 ton ac (calculated on this site) with my budget of 30-35000 and found this Mitakshi AC
MiSAC15INV20 1.5 inverter on flipkart but shud i go for this? Probably this is a 3 star inverter ac. Will this be more energy efficient than a 5star 1.5 ton standard non-inverter split ac? What should i choose in this budget or which is more efficient generally: a 3 star inverter ac or a 5 star non inverter ac. I live in alwar rajasthan which has weather quite similar to delhi. Thanks

Abhishek Jain (Mod)

Hi Kishore,

Mitashi Model (Flipkart Link: http://fkrt.it/pD1hkTuuuN ) has ISEER of 3.6, which would make it BEE 3 star rated. For normal non inverter AC BEE 5 star rating starts with ISEER of 3.5. There are models in BEE 5 star non inverter that have ISEER as high as 3.9 as well. So it depends on which model you are comparing. But still it would be better that many of the BEE 5 star rated non inverter models that you can get in your price range. You can certainly go for this model in your budget.


So can u pls suggest me some of non inverter 1.5 ton 5 star ACs (more energy efficient than this mitashi's 3star inverter ac) and within my budget range, as i m skeptical about relying on a new brand like mitashi.

Abhishek Jain (Mod)

I do not think you can find models with better EER in 30-35K range. There are some with same EER:

Lloyd LS19A5LK
Onida SA185GDR (Flipkart Link: http://fkrt.it/xzAjy!NNNN )


Hi, the article provides a great insight to everything related to air conditioning​. However I'm planning to purchase​ offline.

Going for 1Tonn 3 start Inverter AC.

Hitachi,Bluestar and Daikin doesn't have service centres in my city.

The one's available are Voltas, Lloyd, LG, Videocon, Samsung, Panasonic, Godrej,Haier, and Sharp.
Please suggest a cheap or value for money model. Or may be inder 35k.

Abhishek Jain (Mod)

Hi Yadhukrishnan,

Among all the brands that you have mentioned, I think LG is the best value for money for you. They have several models that are good, but I think you should look at JS-Q12AUXA or JS-Q12SUXD.


Hi, thanks for the reply. I immensely Appreciate it.

The models provided are good on the budget but as I checked with the retailer those two models are out of stock and it would atleast take a week to be available, as of current situation​ I'm opting for JS-Q12NUXA/2017 for 32k with V400 V-Guard Inverter and Installation and delivery charges included. Only downside is the lack of up-down swing(specs from lg website). But I'm hoping that wouldn't make much of a difference ,now would it?

Abhishek Jain (Mod)

That should not be a big problem. I think it is a good choice considering your needs and budget.


Thank you again, just fited the AC and much to my surprise it does have the swing feature.


Please suggest me 1.5 ton inverter a.c best for me .Hitachi or blue star or Volta's or dainik.please suggest also model name .in inverter 5 star blue star or Hitachi best

Abhishek Jain (Mod)

You can look at any of these:

Hi , I am staying in jaipur with a room on 2nd floor and get direct sunlight over the room from terrace and front side. Room dimension are 22ft length 14ft width and 14ft height. Temperature in this part of country is usually above 40 degree. Please suggest me whether I should take a 5 star fixed speed a.c. or an inverter a.c.. I had shortlisted Mitsubishi and daikin. Kindly suggest a model. I think I will need 2 ton ac

Abhishek Jain (Mod)

Hi Irfan,

In Daikin you will have to go for 1.8 ton AC as they either make 1.8 ton or 2.2 ton. And in BEE 5 star range they just have 1.8 Ton. You can look at these models:

Mitsubishi Electric MS-GL24VF
Mitsubishi Electric MS-GK24VA (Amazon Link: http://amzn.to/2qV1bCM )
Daikin FTF60 or DTF60 or ATF60 (the difference between the three is just filters and Smart Phone connectivity, FTF is the basic model).

However I think 2 ton would be better for you than 1.8 ton.


I want to buy Godrej NCW inverter 5.8 ISEER AC. My room requires 2 ton AC but will 1.5 ton inverter ac suffice or should I stick to 2 ton fixed ac. Please advice.

Abhishek Jain (Mod)

1.5 ton inverter AC may not suffice if your usage is also during the day. If the usage is only at night then 1.5 ton inverter AC may suffice.


Am using a fairly old Daikin 1.5 TR FT50BVM. One of the major issues faced is clogging up of indoor unit and air flow blockages giving calling for repeated instances of service and wet service of Daikin is quite expensive. I was recently told that cleaning the plastic filters every week should not be done and instead should be cleaned only once in a month or two. Is that correct? Can anything else be done to prevent repeated clogging.

Also, are Daikin JTKM50 or Hitachi RAU518CWEA suitable potential replacements for dusty environment. Many thanks!

Abhishek Jain (Mod)

Hi Farroukh,

Filter cleaning frequency depends on how frequently do they get dirty. If they get dirty every week, then it needs to be cleaned every week. But then I have not seen such situation. All I know is that dirty filters reduce cooling as well as energy efficiency. You can go for a model with iClean technology. Hitachi RAU518CWEA does have iClean. This technology automatically cleans the air filters. I think that would be a better replacement.


Hi,I want a 1.5 ton ac preferably at BEE 5 star ac or an inverter ac which will save equivalent energy/money ,i live in UP temp is around 46-47C room size 12*12 ,persnally i have chosen bluestar as it has many service centre in my city ,my budget for buying ac is 35k but can expand to 38,500 also please suggest the same

Abhishek Jain (Mod)

Hi Amol,

The best and most efficient models that you can get in your budget are BEE 3 star rated inverter ACs from LG:

LG JS-Q18ATXD (Amazon Link: http://amzn.to/2plxzkK )

LG JS-Q18AFXD (Amazon Link: http://amzn.to/2oA2VBg ) similar model with different design

LG JS-Q18CPXD (Amazon Link: http://amzn.to/2oA7Ban ) ... this is an Amazon only product and I doubt you will get this in market.

LG JS-Q18NPXA (Amazon Link: http://amzn.to/2oA6Nm5 )

Blue Star BEE 3 star inverter AC would be expensive, in fact even their BEE 5 star rated ACs would be expensive. LG is the best in that budget range. Otherwise you can look at these BEE 5 star rated ACs:

Hitachi RAU518KWD (Flipkart Link: http://fkrt.it/SFpEQTuuuN , Amazon Link: http://amzn.to/2pN0WvZ )
Whirlpool 3D COOL XTREME HD 5S (1.5 T) (Flipkart Link: http://fkrt.it/SGYhQTuuuN )
Carrier Superia 5 Star (Amazon Link: http://amzn.to/2p7pv7P , Flipkart Link: http://fkrt.it/SGJhKTuuuN )
LG LSA5NP5A (Amazon Link: http://amzn.to/2p7qEMQ , Flipkart Link: http://fkrt.it/m1YxJ!NNNN )


Best 1 ton 3 star inverter AC (Copper) for a 120-130 sq. ft room.........Hitachi vs Daikin which one I choose?? Please suggest me the best brand among the aboves , along with their best latest series (model no)....
I am from West Bengal..please suggest the best one according to after shell service.
My budget is around 45k.

Abhishek Jain (Mod)

Hi Tanay,

In BEE 3 star 1 ton, Hitachi has 3 models RSG312EAEA (Waza 3200i), RAU312EWEAD (Neo 3200i) (Amazon Link: http://amzn.to/2pkb24s ) and RSB314IAEA (Kashikoi 3300i ... it is actually a 1.2 ton model). And Daikin has just one model FTKH35. The energy efficiency of FTKH35 is close to any BEE 5 star rated non inverter AC. But the Hitachi models have far better energy efficiency ratio of 3.94. So I think Hitachi has better models to offer in BEE 3 star 1 ton inverter.

Also among the 3 models, Kashikoi 3300i is the most feature rich with isense technology (sensors that can optimize performance as per the need of the room) followed by Hitachi Neo. Waza is a basic model.


Hello Sir,

My friend wants to buy 5* inverter AC of 2 Ton for his 200 sq.ft. drawing room. He is living in Delhi and has a budget of 60000. He is living near a big drainage which is 300 meters from his house.

Please tell which is better out of Hitachi RMA524CAEA (2 Ton) and Mitsubishi GN22VF (1.90 Ton) model.

Thanks in advance.

Abhishek Jain (Mod)

Hi Rohit,

It would be a bit risky to go for inverter AC if living close to a drainage. Based on the feedback we have received lately, corrosion can impact PCB. Energy efficiency wise both the models you have selected are quite close. Hitachi model having better cooling capacity will cool faster. Check for the support of these brands in your area, go for the one who is better in your area. Otherwise both brands are premium brands.


Thanks for the reply. Which of these 2 companies have lesser complaints of their ACs specially the PCB?

Else if he does not go for the above 2 models, which non-inverter model he should go with, his usage is 6-7 hrs a day for 6 months.


Abhishek Jain (Mod)

Hi Shakti,

Corrosion is a ticking time bomb with you having no idea when it can burst. Some areas are highly corrosive, so much so that it can get damaged in few months, some are less and thus the PCB can survive for a few years. But no one can tell when it will get damaged. And when the PCB is in outdoor unit, it will get damaged, whatever brand it is. So I cannot tell which brand has lesser complaints.

In Fixed speed, you can look at these models:

Hitachi RAU524AVD (Amazon Link: http://amzn.to/2n0EHm9 )
Hitachi RAU524IVD (Amazon Link: http://amzn.to/2nKvoUL )
Mitsubishi Electric MS-GK24VA (Amazon Link: http://amzn.to/2opgxBL )
Blue Star 5HW26AATU


Thank You so much Mr.Abhishek


How about DAIKIN JTKM50 and FTKP50. Compared between both, which one will be the best?

Abhishek Jain (Mod)

Daikin JTKM50 is the best.


I have just purchased a new AC Hitachi Rau 318awea.This ac has a iseer 3.96 and it's 3 stra rated and consume almost 1030 unit in a year. Is it a low power consumption AC.( my room exposing to sun whole day)
Prasun dey


I am from Ludhiana. need to install ac for bedroom (size-10X10) and roof exposed to sun light.
please suggest best capacity ac.
kindly also confirm if I install 1.5 ton inverter ac for same room seeing very hot summer season ahead, will this affect my electricity bill ?

Abhishek Jain (Mod)

I think 1 ton AC should be perfectly fine for your room. You may install 1.5 ton inverter AC as well because oversizing is fine in inverter ACs, but then in the same budget you can get more energy efficient 1 ton inverter AC as well. What is your budget for this AC?


3 star inverter ac with iseer 3.68 value will be equal to what rating in non inverter ac with bee star rating

Abhishek Jain (Mod)

But then inverter AC has other benefits as they maintain consistent temperature which is more comfortable and also they can work easily with power inverters or solar inverters because they do not have high current requirement for startup.

Abhishek Jain (Mod)

It will be equal to BEE 5 star rated non inverter AC with EER around 3.68.


Hi Abhishek,

Need your advise, I'm staying in Jabalpur & looking for inverter AC's. Room size is around 200 sqft. I'm confused between 2 ac's @ the moment. Can you recommend which ac is easy on wallet & best to beat the summer & winters...

1) Daikin FTHP50 , 4 STAR ( Have both features hot & cold but cooling limit is max 46. Will this be effective if outside temp goes above 46? Is it a good
choice considering other options in market? Will this consumes less electricity?

2) Daikin JTKM50 , 5 STAR ( Have only cooling feature but also have cooling limit as above & misses out on heating option)


Hello Mr Abhishek, For 1 ton A/C with Inverter technology.
Does Interver AC have ISEER rating or BEE rating?
Can Inverter AC also have 3Star & 5Star rating?
What is DC 12 Inverter AC?

I search online for Daikin, BlueStar, LG, Whirlpool, but can't decide. as there is No direct comparison between models from different brands is available.
Which model would you suggest? My budget around 30-40K.

Abhishek Jain (Mod)


ISEER and BEE ratings are two different things. ISEER is a measure of energy efficiency (just like km is a measure of distance). And BEE (Bureau of Energy Efficiency) is a Government of India organization that gives star ratings based on a criteria for ISEER. So they divide the range of ISEERs available in market and mark them 1 Star, 2 Star, 3 Star, 4 Star, 5 Star. So Inverter AC will certainly have its ISEER value (which is its measure of energy efficiency) and based on that ISEER value BEE will give star ratings.

Inverter ACs also have 3 star and 5 star.

I have not heard of DC 12 inverter AC.

You can look at these:

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 )


Biswajyoti Sarkar

what is the best 1.5T inverter ac??

Biswajyoti Sarkar

First of all thanks a lot for your knowledge....
i want to buy 1.5T Inverter AC (Copper).. Budget is not a factor...... what should i buy???

Abhishek Jain (Mod)

You can look at Daikin JTKM50 or Hitachi 5400i or Blue Star 5CNH18PAFU. These would be the best models in copper.

Biswajyoti Sarkar

i live in a small town.. blue star and daikin serviceis not up to the mark in our city... can you suggest some voltas models....
now i am thinking to buy inverter 3 star or inverter 4 star..... BTW our city is in west bengal... too much rain and humidity...

Abhishek Jain (Mod)

Hi Biswajyoti,

Voltas only has 3 star or 5 star. So you can look at these 3 star rated models:

Voltas 183V EY (Flipkart Link: http://fkrt.it/9ZpZDTuuuN )
Voltas 183V IY (Amazon Link: http://amzn.to/2nQDiNU )

Biswajyoti Sarkar

thanks a lot
my local dealers offer me Voltas 183v DYb @ Rs 45500/- and 183V ey at RS 47000/-
which one is better ac and better deal.. ... thanks in advanced...

Abhishek Jain (Mod)

183V EY has more energy efficiency than DYb, but the difference is not huge. You may go for 183V DYb.


Sir, in lg atxd or cpxd both are aluminium condenser?

Abhishek Jain (Mod)

Yes. Both have aluminium alloy condenser.


Sir I need 1 ton inverter split AC with copper condenser, rototary , gas r410 a ..which is t best model cheap and best?

Abhishek Jain (Mod)

If you are looking at cheap ones, then these are the ones that would be cheapest:

Hyundai HS4I54.GCO-CM (Flipkart Link: http://fkrt.it/8nFhcTuuuN )


Hello Abhishek, I compared both products ATXD and CPXD on LG's Official Website. The only thing in ATXD is that it has mosquito away feature; everything else is same. Today i have ordered 2 CPXD via lightning deal for 35.5k each, is it a good choice? Or ATXD has more good features that LG didn't mentioned in comparison?

Abhishek Jain (Mod)

They are similar. CPXD is perfectly fine.

Nayan Jyoti Fouzdar

Hi Abhishek, first of all thanks a lot for this amazing knowledge sharing & I really appreciate the details.
LG model no q18cpxd is costing me 35k approx and it is dual inverter 3 star. I stay in Gurgaon and it is ground floor. Do you it would be a good option?

Abhishek Jain (Mod)

LG JS-Q18CPXD is a good model with good energy efficiency. I think it is an Amazon exclusive deal. Are you getting it offline? There are more models on Amazon with similar energy efficiency (slightly different design):

LG JS-Q18ATXD (Amazon Link: http://amzn.to/2plxzkK )

LG JS-Q18AFXD (Amazon Link: http://amzn.to/2oA2VBg ) similar model with different design

LG JS-Q18CPXD (Amazon Link: http://amzn.to/2oA7Ban ) ... this is an Amazon only product and I doubt you will get this in market.

LG JS-Q18NPXA (Amazon Link: http://amzn.to/2oA6Nm5 )

Nayan Jyoti Fouzdar

Thanks for the quick response.I am getting CPXD offline as well. Which one would you suggest out of the above? Would you suggest for Samsung as well?

Abhishek Jain (Mod)

Energy efficiency wise LG has better models in BEE 3 star inverter as compared to Samsung. So I would suggest LG. All these models from LG that I have given you are having similar energy efficiency. JS-Q18ATXD is the most feature rich model with good filters and Dual Inverter Compressor. JS-Q18CPXD would be the second best in terms of features.

Hi Abhishek,
I need to buy a 1.5 ton 5 star inverter AC, but I am actually don't know which one is better to me. It's my first AC please suggest me any specific AC which is best to me, I contacted one of my Father's friend local dealer he is saying their is no such difference in 3 star or 5 star AC, He suggested us Lloyd 3 star AC, and I am very confused now, I even don't know Lloyd AC is inverter AC or not. Please guide me. Also do I have to purchase inverter AC or the normal one.

Abhishek Jain (Mod)

Hi Sanjay,

There is a lot of difference between 3 star and 5 star. But the right choice depends on a lot of things:

1) You must size the AC properly. In case of inverter ACs oversizing is fine but undersizing is bad. In case of non inverter ACs, undersizing is fine (from electricity consumption point of view) but oversizing is bad. And sizing depends on your city, room's location, room's size, etc.

2) You must choose the right star rating depending on your annual usage in hrs/year. The calculator on this site can help you not only choose the right size, but also gives electricity costs per year for using various star ratings. You can evaluate the cost of buying and cost of using various star ratings depending on your usage and tariffs. The calculator has tariffs of various cities built in.

3) Finally all depends on your budget. You can save electricity with BEE 5 star rated inverter AC, but what's more important is to find if it fits in your budget. Suppose you want to spend only 35-40K, then you may not get a BEE 5 star rated inverter AC. Please note that people spend for efficiency because: a) costs of electricity is rising b) As technology is improving, more efficient ACs are coming. BEE 3 star rated ACs available almost 3-4 years back are now out of market. So things are improving and if you want to invest in technology then just try to find the best in your budget.

So as a strategy we ask people to calculate the right size which can be done using the calculator on this page:


and then we ask people for their budget and suggest the most efficient that they can get in that budget. Because Star Ratings do matter.


Hello Abhishek,

I am looking to put split ACs ( preferably 5 star Inverter ) and are confused between Blue Star Q series , P series and the LG Dual inverter Series. Our requirement is for 1.5 Tons and 1 ton. Our usage would be all year round so ideally 1600 hours in a year in Mumbai.I would love to get your opinion on the same and if you can suggest any other alternative like Daikin as well, I would be open to that option as well.

Abhishek Jain (Mod)

Hi Samyak,

Daikin JTKM series, Hitachi Kashikoi 5400 series and Blue Star P series are the best series from these premium brands. If you can go for any of these, then that would be the best.


Hello Abhishek,

Thanks a lot for the great insight and explaining the technical nitty-gritty to be considered while buying an AC, which i was not aware of this till i read your article. After using the calculator shared in one of your articles,which suggests the tonnage requirements based on several factors.I have decided to buy 1-1.2 ton Split inverter AC,please suggest which option should i go for in the price range of 25k to 30k.

Abhishek Jain (Mod)

Hello Mr Singh,

It is usually difficult to get 1 ton inverter AC of premium brands in this budget. But you can look at these available on Flipkart:

Samsung AR12MV3HEWK (Flipkart LInk: http://fkrt.it/vKgm3!NNNN )
LG JS-Q12BPXA (Flipkart Link: http://fkrt.it/82y2oTuuuN )

Hi Abhishek,

I want to buy 1.5 ton Inverter ac with 5 star . Which one is the best Daikin JTKM16 or Blue Star P series ?

Abhishek Jain (Mod)

Hi Ashim,

Daikin JTKM50 is the best BEE 5 star rated inverter AC model in the market.



I want to buy an 1.5 ton split ac 5star a/c with high EER and power saving for my living room of 170 sq.ft Please suggest me the models should i consider from the following brands.

1. Hitachi
2. Mitsubishi heavy Industries.
3. daikin

Abhishek Jain (Mod)

In Hitachi you can look at these:

RAU518AVD (Amazon Link: http://amzn.to/2o6QMGi , Flipkart Link: http://fkrt.it/~Z~fS!NNNN )
RAU518HWDD (Amazon Link: http://amzn.to/2nzO62R , Flipkart Link: http://fkrt.it/Pq3IDTuuuN )

FTF50 (Amazon Link: http://amzn.to/2oadGwW , Flipkart Link: http://fkrt.it/~PbcS!NNNN )

In Mitsubishi Heavy, you can look at this one:

Mitsubishi SRK20CLS-6


Which one is best LG JS-Q18ATXD or LG JS-Q18NPXA

Abhishek Jain (Mod)

JS-Q18ATXD has better filter and mosquito away technology. So it is more feature rich. Energy efficiency is the same.


Dear Abhishek
I have a bedroom (Usual occupants 2-3 person) size (16 *10 ft height 9 ft).Its on the second floor and its outwalls faces direct sunlight from North aswell as west throughout the day in summers.This room also has an attached dressing area (Size 6*4 ft height 9ft) which has no door so cooling is shared there too.
Initially this second floor was the top floor so using the tonage calculater on eta website i installed a BEE:3star, 2Ton ,Ogeneral hyper tropical machine with an EER of 3.2,Model no.ASGA24ACT as was recommend there.With this the room becomes too too cold and even at low fan speed and temp set to 28 ,the machine has to be switched off again and again and more so during night.To add to my chilling trouble , this room is now no longer the top floor ,ie: another floor been added above it.So i want to decrease the tonage,aswell as decrease the BTU so that i get a more comfortable cooling instead of very chilling peak temp.
I have finalized two machines of ogeneral, ASGA18JCC 1.5t inverter and ASGA18FTTA 1.5t hyper tropical 5 star.Both cost the same (50k)and both have same eer : 3.51,almost similar wattage and amp too.I want to go for inverter ,as Its a bedroom so i want more steady cooling.Conventional hypertropical machine seems to fail in maintaining a steady temp.and because of tentative power saving of inverter,exceptional moisture removal,but my concerns are:
1.Which one is a long lasting and a better product material wise and technolocy wise.
2.Does inverter machine come with aluminium condenser ?because it must be a con if thats true.
3.The operating temp of inverter is 18- 46 degree,however hypertropical has an operating temp. ranging upto 52 degree.Will the Inverter machine fail me at <46 degree heat which is quite possible in delhi /ncr.
4. Pcb in inverter ac are expensive to replace. Can you recommend any other machine more suitable to my conditions
Regards and with thanks for helping.
Satish vats

Abhishek Jain (Mod)

Here is my response:

1) Both have similar type of heat exchangers and similar type of corrosion protection (for heat exchangers and outdoor units). The compressor is different as one has inverter and other is non inverter. So durability wise both look similar. Technology wise inverter is more advanced.

2) Both of them have copper condenser. It is mentioned Blue Fin Condenser in both.

3) Operating temperature of 18-46 means that the AC will work well if the temperature of the air surrounding it is between these two temperatures. If temperature of air surrounding the outdoor unit goes beyond 46, then it will not work well. So if you keep the outdoor unit in direct sunlight, then in peak summers it may not work in Delhi. But if the outdoor unit is in a shade where the temperature is not as high, then it will work.

4) You can look at Blue Star 5HW18SBTU or 5HW18ZBRTU or 5HW18ZBWTU. It has copper and Blue Star ACs also operate till 52 degrees. It's EER is 3.7. Even these have blue fin condenser. Or you can look at Hitachi RAU518AVD (Amazon Link: http://amzn.to/2nbzNy4 , Flipkart Link: http://fkrt.it/h9Nl1TuuuN ) or Hitachi RAU518HWDD (Amazon Link: http://amzn.to/2mL4JK1 , Flipkart Link: http://fkrt.it/RE!cs!NNNN ). Hitachi also usually has high operating temperature.


Dear Abhishek
Continuing from where I left which of 2 is better.o general. ASGA18FFT OR ASGA18FFTA. Which is more efficient and which would consume more power as they both have same EER but different Condensers.
Thanks a lot
Satish vats

Abhishek Jain (Mod)

The inverter model is currently not rated by BEE (because star rating is not mandatory currently). And that is why they have not mentioned ISEER of the inverter AC. ISEER is seasonal energy efficiency and that is the ideal way of measuring an inverter AC because all throughout the year it runs at a different tonnage. But here they have mentioned EER. Now theoretically if you compare two ACs (one inverter and one non inverter) of same EER, then the inverter AC model would be 20% more energy efficient. If this inverter AC gets rated on BEE star rating, it would be BEE 4 star rated at least. So Inverter AC would be more power saving.


Another very useful information. Thanks Abhishek

Abhishek Jain (Mod)

The link from Amazon that you have shared is for 2016 model. 2017 model is copper condenser. And I know a few people who have purchased it for 31-32K from the market. Online on Flipkart it is available for cheaper.

P.Yamuna Baby Ganga

Sir, Which AC is best LG JS-Q18ATXD
or Samsung AR18MV3HETR
Is Working well Mosquito Away feature or not? Mosquito Away is not working which is worthlesd in YouTube is it right?

Abhishek Jain (Mod)

LG JS-Q18ATXD is better in terms of energy efficiency (electricity saving) as compared to Samsung AR18MV3HETR. LG is also bigger brand in terms of market share in ACs. I think LG JS-Q18ATXD would be a better choice. Mosquito away works by creating low frequency waves that irritate mosquitoes. And it does work.

UP wale bhaiyya

Dear Abhishek. I am planning to buy SAMSUNG 1 Ton Inverter Split AC White (AR12MV3HEWK) in Pune. It is 3 star inverter AC with ISEER=3.61. Being in pune i will hardly use it for 2 months a year since rest of the time weather is humane. Would it be a wise to go ahead as i am getting lucrative deal on flipkart toady?

Abhishek Jain (Mod)

Hi Vimlesh,

The deal is quite attractive you may go ahead with it. I would say even this deal is fantastic: Whirlpool Fantasia 1 ton (Flipkart Link: http://fkrt.it/1~AE7!NNNN )


Thanks Abhishek for replying.. really appreciate! I ordered the same yesterday & got it delivered today.Flipkart scheduled installation tomorrow, hope it would be pleasant.

Abhishek Jain (Mod)

Great. Do let me know your feedback on the same.


Flipkart gave installation task which is free with the product to Jeeves which sent 2 minor kids for installation. When these kids saw installation has to be happened on 9th floor they got scared & run away. Later on Jeeves cancelled the installation & flipkart again raised the Installation request with Jeeves only. I am thinking of returning the product now. :(


Dear Abhi, Went through a lot of comments here and decided to write to you. I am from Mumbai and wish to buy two 0.75 TR Inverter based air conditioners. One of the only brand which i have been able to find as yet is Daikin FTKP25RV16 series.
1. First of all is Daikin a good brand to buy ac and will service ever be a problem from your expertise ?
2. Are there any other brand which would offer 0.75 TR ACs with inverter tech which has an equivalent 4 star rating
3. Does the above Daikin series have corrosion protection and other allied product parts which will enhance the Longevity of the AC.

Thanks for your time, Looking forward to your revert

Abhishek Jain (Mod)


Here is my response:

1) Daikin is a fantastic brand. A friend of mine got a Daikin 0.75 ton inverter AC installed 3 years back and it is working awesome with no issues. This is in Mumbai.

2) Blue Star 5CNHW09PAFU (Amazon Link: http://amzn.to/2n5TMS0 ) is another great 0.75 ton inverter AC. Blue Star has a 3 star rated one as well: 3CNHW09CAFU. But these are the only ones that are star rated. I know Mitsubishi Electric also used to have one. But I have not seen it lately.

3) If your environment is corrosive, everything will fail, be it copper or aluminium (with or without corrosion protection). Copper is easier to repair, but aluminium needs replacement. Corrosion protection just delays the failure. Daikin does not mention of corrosion protection for all its ACs, but they have copper. Blue Star mentions corrosion protection as well as copper.


I am planning to buy 1.5 ton Inverter AC for my chennai home which need to have some air purification as my spouse is allergic to dust, smell and temperature and frequent cold infections, my first preference is performance, durability and reliability and budget is last. I have sort listed BSA18BEYD(LG), JTKM50SRV16 (Daikin) and P Series 5CNHW18PAFU (BlueStar). But could not come to a conclusion. Please suggest a model from this list or any thing else for my requirement.

BSA18BEYD - Does it has 3M Filter? Digital display in LG models is attractive.

Blue Star - Digital display used only to display set-temperature or any thing else like power-consumption in .kw and fan speeds?

Abhishek Jain (Mod)

From efficiency point of view JTKM50 would be the best followed by Blue Star P Series. JTKM is anti pollution series from Daikin where they use filters to remove PM 2.5 particles which is the smallest of particle causing pollution. It also has steamer discharge technology which is Daikin's technology for its air purifier, which as per Daikin is "one of the most effective ways to eliminate bacteria, viruses, mould & allergens from the air."

Blue Star also has a lot of filters for allergens, odur, bacteria, virus, etc.

Feature wise they are similar. Daikin is more efficient, but would be a bit costly as well. Blue Star I think would be a good choice. It also has precision cooling where you can change temperature even to 0.1 degree.

Usually I have not seen many models that display kW power consumption (although it is not a difficult thing to incorporate). You can get a lot of information on the remote not on the indoor unit display.


Thanks Abhishek. Are there any difference in Compressor and Condenser between JKTM50 and P Series?
I understand that P Series has blue fin coating. Do we have this in JTKM?

JTKM50 is only Rs.700 more than P Series. Which one you would pick if you were given to vote?

Abhishek Jain (Mod)

Hi Sam,

JTKM does not mention of corrosion protection, so I assume it does not have it. As it is corrosion protection just increases life a bit, but if environment is corrosive, even that will fail after sometime. Corrosion can take away any appliance. I am not sure where you checked the price, but on Amazon P Series is for quite reasonable price check this: http://amzn.to/2p4iEb4

Both are good, I would say if P Series is much cheaper, go for it. But if the difference is just Rs 700, I would say Daikin is a bigger brand.

Abhishek Jain (Mod)

Please note, that usually Daikin does not provide connecting pipes which need to be purchased while installation. Whereas costs in most other brands include pipes for installation. There is extra 2-3K for that.


Could you please compare the filters used in these models and tell me which one is good.?
1.LG model has "Micro Dust Protection Filter"?
2. Daikin has "streamer discharge Technology"?
3. BlueStar - Active Carbon Filter, Cold Plasma Filter, Catechin Filter, Silver Ion Filter, Anti-Bacterial Filter . Does 5CNHW18PAFU have all these filters?

Will they work all time when ac is running or do we have an option to on/off these filters?

Abhishek Jain (Mod)

Currently we do not have research to make comparison on effectiveness of these filters. So I am sorry, I will not be able to help you on this.


Which is the best air conditioning brand in india. mitsubishi vs o general which is better?

Abhishek Jain (Mod)

I would suggest that you better look for a good model that fits in your budget rather than looking for a brand. Mitsubishi and General, both are premium brands.



Would like to buy 1.5 T Inverter A/c for bed Room. Want the absolute best option of cooling only Inverter A/c with high energy efficiency and best cooling. Highest quality of fool proof running (rugged - Chalta Rahe without tension). Price no barrier. Stay in New Delhi. Please advise.

Abhishek Jain (Mod)

Hi Saurabh,

These are the most energy efficient 1.5 ton inverter ACs:

Daikin JTKM50
Hitachi RSA518CAEA or RSB518IAEA
Blue Star 5CNHW18PAFU (Amazon Link: http://amzn.to/2ndQ71o )
Mitsubishi Electric MSY-GK18VA


What is the difference between Blue Star BS-5CNHW18PAFU-SMRT, BI-5CNHW18PAFUSMRT and BO-5CNHW18PAFUSMRT? I see BS-5CNHW18PAFU-SMRT on Amazon.

Abhishek Jain (Mod)

Blue Star uses BI- for indoor unit model number and BO for outdoor unit model number. I am not sure where "BS" came in. They are all the same model number 5CNHW18PAFUSMRT . Blue Star has two models: 5CNHW18PAFU and 5CNHW18PAFUSMRT .... one has SMART features (can be operated using smart phone, etc) and a similar one without smart features.


Thanks Abhishek,

How about Mitsubishi Heavy SRK 18 YL-S? And from the list here .. what would be ideal for a rugged machine and service?

Abhishek Jain (Mod)

Hi Saurabh,

This model is not yet rated on BEE star rating (MHI has not got it rated as right now BEE rating is not mandatory for Inverter ACs). But looking at its tech specs I feel that it should be BEE 5 star rated, and being MHI it surely must be good. You can certainly go for it. I cannot tell about service because MHI as a brand does not have a big market share. Their presence in large parts of the country will not be too good. But if they are good in your city/location, then you must go for it.


Thanks Abhishek


Hi Abhi,
First up all thanks for your reply, yesterday i purchaised LG AC (JS-Q12NUXA/2017) Inverter (3 Star and Full Copper ) AC, Did you know about this model ? i just checked the website LG/Amzon/Flickpart but i cannot see the particular number or model now am worried about that , i saw just similar model (JS-Q12AUXA) is it same then why different number .


Hi Kishor, much this model cost you excluding installation ?

Abhishek Jain (Mod)

It is a BEE 3 star rated AC registered with BEE (I can see it in BEE's database). However, it does not show up on LG's website, which is kind of strange. But then it does happen.


Thank you Abhishek


Hi Abhi,

Thanks for your advice for selecting right things, i am plan to buy LG 3 star smart inverter AC (1Ton),i went shop today they told me LG-Q12NUXA/2017 Model but i search through LG website and filckpart/amazon i cant find those number did you know this model ? i am confused now ,can i go for that?


Hi Abhi,
I am confused to buy daikin ftkh50 or bluestar ncwh18nafu , which one is better ?

Abhishek Jain (Mod)

Difference is not much in terms of efficiency. But FTKH has less cooling capacity as compared to 3CNHW18NAFU. So I think 3CNHW18NAFU would be better.


but in which feature is good and long lasting ?

Abhishek Jain (Mod)

Both are top brands and equally good and long lasting. Features wise Blue Star is good.


ok and thanx a lot abhishek but need one more favour which model is good in bluestar N - series, P- Series or T- Series or C - Series ?

Abhishek Jain (Mod)

P Series is their best series with BEE 5 star rating. Within BEE 3 star rating, T series is most efficient, followed by N Series and then C series.


ok thanks ,
now i ignore daiking and finalize bluestar T series and Hitachi Neo 3200I RSH318EAEA Inverter , so which one is better from these ?

Abhishek Jain (Mod)

Hitachi Neo 3200I RSH318EAEA Inverter

Abhishek Jain (Mod)

Great! Do let us know your feedback on the same.


ya sure once i will get the delivery and will work it properly then will give feedback
