In this post, I am going to list down the Best Inverter ACs in India For Home and Office use For 2019.

The Inverter Air conditioners are more effective and utilize less power when compared with the Normal ACs.

An Inverter AC adapts its speed depending on the heat load in the room. Unlike the regular Split ACs, The Inverter Air conditioners have shifting speed motors that adjust their speed according to the requirement. So, Obviously, they consume 30- 40% less electricity.

According to Bureau of Energy Efficiency, an Inverter AC of BEE 3 Star Rating is 7% more energy efficient than a BEE 5 rated normal Split AC. Please note that the Inverter technology is available only for the split ACs.

With Normal ACs, whenever the compressor starts, there will be a slight fluctuation, and when the compressor runs, the room gets chilly, and when it shuts off, the room might get a little bit warm.

But, that’s not the case with the Inverter AC, when you set temperature, After some time, the temperature will be almost constant, and you don’t even notice if the compressor is running or not.

We Highly recommend you to read the AC Buying Guide at the end of the article to get in-depth knowledge about all the latest Air Conditioner technologies.

Introduction to Inverter ACs

The compressor is the heart of the AC. In a traditional AC, the compressor switches on and off at regular intervals.

You have temperature settings in any AC. When the AC cools the room up to the set temperature the compressor switches off. It remains so until the temperature in the rooms goes up again. On sensing the same, the compressor starts working again repeating the same procedure.

Coming back to the inverter ACs, the compressor does not switch off at all.

Naturally, you might ask as to how this situation can be better. You can compare the working of the inverter Air Conditioner to the accelerator of a car.

The moment you sense you are speeding too much, you take the foot off the pedal. Thus, you ensure that you provide less power to the vehicle thereby slowing it down automatically without applying the brakes.

Similarly, when you feel the need to speed up the car, you press your foot down again and provide the requisite power to fuel the engine. The inverter AC units work in a similar fashion.

Difference between an Inverter AC and a non-inverter AC?

This is a good question. You can see the differences unfold as you go deep down into the article.

The basic difference between the two is that the compressor in an inverter AC works continuously whereas it switches between on and off in a non-inverter AC.

The inverter AC units work at variable speeds whereas the non-inverter AC units do so at fixed speeds. This enables the inverter ACs to adjust their tonnage according to the size of the room. The normal AC units do not have this ability.

These are the basic differences. We shall go into the details of the individual differences at the appropriate time.

In order to understand the differences between the normal ACs and the inverter ACs, one should have a background into the working of these ACs. Let us look at the same in the following couple of paragraphs.

The working of the normal ACs

The Window AC units are literally out of fashion. Hence, we shall look at the split AC or the ductless ACs as they are called in many parts of the world. Of course, the technology in use in both these variants is similar in many ways.

Let us concentrate on the working of the split AC. It involves the use of principles of evaporation, compression, and condensation.

The components of the split AC are divided into two parts, one placed outdoors and the other indoors.

An insulated pipe connects both these separate units. The working of these ACs is elementary. It involves the circulation of a compressed gas refrigerant that cools the air inside the house.

Air conditioning units outside a building

This entails that the refrigerant has to be re-cooled and condensed at regular intervals. The hot air outdoors is the best medium to ensure this functionality. The system makes use of a fan to suck the air from outside and condense the refrigerant.

Let us look at the major parts of the split AC

CompressorCondenser CoilsFansEvaporator coilsAir filtersDrainage system

The compressor is the heart and the soul of the AC. In a split AC, you find this component in the outdoor unit. The main function of the compressor is to ensure the circulation of the refrigerant between the condenser and the evaporator coils. It does so in a closed loop.

The coils are a network of tubes filled with the refrigerant (usually Freon). The condenser coils have the responsibility to eliminate the heat from the heated gas refrigerant and cool it into the liquid form again. The coils allow the absorbed heat to escape into the outside air. These condenser coils form a part of the outdoor unit.

The fans have the role of pulling the hot air from the condenser coil and disperse the heat. They are also situated in the outdoor unit.

These coils work in the opposite fashion to the condenser coils. These coils contain the refrigerant for removing the heat as well as the moisture from the air whereby the refrigerant evaporates into the gaseous form. You find these evaporator coils in the indoor unit.

The job of the air filters is to trap the dust, pollen as well as other airborne particles and prevent them from entering into the air conditioning system. These filters play a great role in ensuring the quality of air inside the room.

naturally, you find this system outdoors. Water is an important by-product of the condensation process. You need to flush out this water from the system. There is an urgent need to keep this system in perfect working condition. Any clogging of the drain pipes can affect the functioning of your air conditioner.

Refrigeration cycle: 1) condensing coil, 2) expansion valve, 3) evaporator coil, 4) compressor

Now that you have seen the different parts of a split AC, you need to understand how it works as well. You can break down this system into four main parts.

1. The first step is the compression of the gas and converting it into a high-pressure hot liquid.

2. The condensation of this liquid is the second step in the process. The process takes place when the hot liquid flows through the condenser coils. The heat escapes outdoors and the liquid becomes cold. However, the liquid is still under high pressure.

3. The expansion valve has the role of converting the high-pressure liquid into a low-pressure liquid.

4. The final step involves the passing of this low-pressure liquid through the evaporator coils where you can see the absorption of the heat from the room. This heat converts the liquid into gas. Now, as the heat is absorbed, you get the cooling effect inside the room.

The entire process keeps on repeating.

In the regular AC, you find that the compressor works at full capacity and ensures that the room temperature reaches the desired level. On doing so, the thermostat senses the same and makes the compressor switch off. The fan takes over and enables the circulation of the cool air inside the room.

As the room temperature rises, the thermostat sends a signal to the compressor to start working again. This process continues until the time you switch off your AC.

The Working of Inverter AC

The basic process is the same as in the case of the regular ACs.

The major difference is that the compressor does not switch off in the inverter AC. The system ensures that it gives more power when the unit needs it and reduces the power when it does not.

How does the AC determine the amount of power it needs to deliver?

This depends on the temperature of the incoming air as well as the thermostat setting.


The system uses an inverter to control the speed of the compressor motor. This helps to regulate the temperature levels.

Comprising of a variable frequency drive and an adjustable electrical inverter, they are able to regulate the speed of the motors. The system works by converting the incoming alternating current into direct current. Using a modulation process, this system can produce the current of the desired frequency.

This system gauges the temperature of the incoming air and adjusts the speed of the motor accordingly. Hence, this accounts for the fluctuations in the load as well.

The inverter ACs are systems that work at varying speeds as compared to the regular ACs that perform at the peak levels at all times.

Advantages of Inverter technology?

The advantages of using the inverter technology are obvious. Let us look at them in brief.

1. The inverter AC units consume less power in comparison to the regular ACs.

2. The inverter AC units work at varying speeds and tonnage capacities. This is very much unlike the regular AC units that work at fixed speeds and tonnage.

3. They maintain the temperature level in the room according to the thermostat setting accurately.

4. In comparison to the regular AC units, the inverter units make less noise.

The following example should make things very clear.

You know that every AC has a maximum peak load. It can be a 1-ton AC or a 1.5-ton AC depending on the size of the room.

The problem with the normal 1.5-ton ACs is that they run at the peak power requirement as long as the compressor is functioning.

This is not the case with the inverter AC. It draws as much power it requires to keep the compressor motors running. Since this system works at varying speeds, the power consumption varies accordingly. Hence, you experience saving of power in the long run.

When you speak about the advantages of the inverter technology, you should have an idea about the drawbacks as well.

The biggest drawback is that inverter ACs can be more expensive than the regular ones.

However, it makes up for the fact by reducing your electricity consumption bills by more than 30%. Hence, you can recover the excess cost in a minimum of two years.

Inverter AC vs BEE 5-Star Normal AC

Speed / TonnageAutomatic adjustmentPower consumptionCosts

The normal AC units work at fixed speeds and tonnage levels whereas the inverter AC units have the ability to work at varying speeds and tonnage. This is one of the biggest distinguishing features.

The inverter AC units have the ability to adjust according to the temperature of the room. The regular AC units lack this ability.

Statistics show that inverter AC units consume far less power than the normal units. In fact, a 3-star BEE inverter AC is 7% more efficient than a 5-star non-inverter AC.

An inverter AC can definitely cost more than a regular BEE 5-star AC. However, you can compensate by saving on your electricity consumption.

Power consumption: Inverter AC vs Non-Inverter AC

You have ACs of varying capacities and efficiency ratings. In the normal course, the 5-star ratings are considered the most energy-efficient systems.

Normally, people install AC units of at least 1.5-ton capacity. Hence, we shall compare the power consumption of a 5-star non-inverter AC with a 3-star inverter AC. We shall also look at the comparative 5-star inverter AC to understand the benefits that accrue to the consumer.

Annual Electricity Consumption (Units or for 1600 hrs) BEE Data

As per BEE statistics, a 5-star non-inverter AC of 1.5-ton capacity consumes 1130 units of power in 1600 hours.

The corresponding figure for a 3-star inverter AC is 1077 units in 1600 hours. As you go for higher efficiency inverter ACs, the power consumption reduces to 972 units and 815 units for a 4-star and 5-star inverter AC respectively.

This is ample proof that inverter ACs can help in saving considerable power.

How does an inverter AC save power?

The regular AC cools the room a little below the thermostat setting and switches off the compressor until the room becomes warm enough. On sensing the warmth, it starts the compressor again. This process of switching the compressor on and off consumes higher power.

The inverter AC units, on the other hand, works at double the capacity to cool the room faster and then slows down the compressor motor considerably to maintain the cooling throughout. As and when the temperature inside the room rises, it releases more power thereby controlling the use of electricity throughout.

We shall see a small example to prove this fact.

A 1.5-ton inverter AC will initially run at 150% of its speed to cool the room faster. On doing so, it reduces the speed to around 10% so as to maintain the requisite temperature. This varying speed and tonnage can result in the saving of power. The compressor does not switch on and off at regular intervals thereby saving power as well.

Star ratings for Inverter AC

Just as any other electrical or electronic appliance, you have star ratings for inverter Air Conditioners as well. The ratings depend on various factors such as power consumption, efficiency, etc.

The higher the star rating the higher will be the efficiency.

At the same time, the price of a 5-star inverter AC will definitely be higher than that of a 3-star inverter AC. Naturally, the power savings in the higher rated version will be more.

What is a dual inverter AC?


The dual inverter AC is an improvement on the normal inverter AC in the sense that it has dual rotary motors with wider rotational frequency.

You see an immediate surge in the efficiency levels with faster cooling and emission of lesser noise.

It works in a similar fashion to the normal inverter AC by regulating the speed of the compressor motors. However, the dual inverter AC performs the role with a higher degree of efficiency.

Hence, it ensures further savings in power bills whereby you recover the cost in double quick time.

In the normal course, ACs work well when the outside temperature is below 46 degrees Celsius.

The dual inverter ACs can function when the temperature levels rise above 46 degrees up to a maximum of 52 degrees.

Thus, you can see that the dual inverter AC can work in extreme conditions as well.

Air Conditioner Capacities

In general, A 0.75 Ton AC is suitable for Small bedrooms and a 1 Ton Split AC opts for Bedrooms and Small Conference rooms, office cabins.

1.5 Ton Air Conditioner is required for Master Bedrooms and 10 Seater Conference rooms. If you are looking to install an AC for your Living Room or Large Office Workspace, you have to opt for a 2 Ton AC.

Summer temperatures of your Place, Window Space at your Room should also be taken into consideration. Also, If you are living on the 2nd Floor or above, the room will be warmer due to the rising warm air. So, make sure you select the AC Tonnage according to the requirement.

Final words

You have seen the concept of the Inverter AC. Now, you are aware of the benefits of using the inverter technology as well.

However, it is of utmost importance to ensure that you maintain your AC systems well by cleaning the filters and ducts regularly. This enables you to save considerable power and increases the life expectancy of your inverter Air Conditioner.

Daikin – FTKF50TV16U, JTKJ50TV16U, FTKG50TV16U

All the above models are 5 Star Inverter and energy efficient. It is very normal that Dealers will change the Price of the product and provides offers according to their wish. You can also make use of Amazon Festival offers during Diwali and save money.


I bought a Daikin 1.5 ton Inverter ac. It worked very well and my electricity consumption was very low.

However in 7 months it developed a leak in the coils and it was changed under warranty. This time under their advice they coated a solution to prevent corrosion and charged Rs 1500.

Iam quite worried about the corrosion and if it would reoccur once again.

Rajib Mazumdar

Hi I am willing to Purchase AC of 1.5 T one and 2 Ton one.My only criteria is to consume less power bill.It may be inverter AC or dual inverter AC.Kindly guide.


I have my office near sea, about 1km, in Mumbai. I have to buy three 1 ton ac and two 1.5 ton acs (area 310sqm). I want inverter acs as it gives constant cooling. However, I was told not to buy inverter ac for coastal areas. Blue Star dealer said it’s life will be 3 yrs only. We have office opening on 20 Aug. Really worried. Please suggest if we go for inverter or on. Which brand is good for such conditions? Thanks.

Kitchenarena Team

Some of the 2017 Version Inverter Air Conditioners are prone to corrosion. 2018 models have better PCB protection and the newer models also have higher operating temperature and they can work properly even in extreme heat. Go for premium brands like Daikin, Hitachi or Blue Star. LG Dual Inverter Air Conditioners are also good. Make sure you look for PCB warranty before buying an AC. Also, go for the brand that provides corrosion protection to the AC.


Hi Chaitanya,

I am from Kolkata, WB. I am planning to buy an AC and need your assistance to select the right product from the market.

Room description:- Size- 120sqft., 1st floor of a 5 storied building.

Daily usage would be around 3-4 hrs. Preference 3 star AC, as within budget. Considering the above fact, which one is better- Inverter AC or Non-verter AC (Preference Inverter AC due to low power consumption)? Which is better Daikin/Hitachi? Advise the model no of your suggested brand..



Thnxs for ur guidance

Pls suggest me for buying AC for my personal use, with low unit consumption.

No.of person’s- 2

room size- 11*10 ft at first floor after that no floor

If I will run AC minimum 10 hrs, how much electricity consume?

I am living in Chennai.

Kitchenarena Team

It is better to go with a 1.5 Ton Air Conditioner as the ceiling of your room gets direct sunlight during the day. Higher the star rating, lower will be the power consumption of the AC. Also, it is better to go with Inverter technology AC as you will be using the AC for more than 10 hours. You can have a look at the below models.

could you please ping me which AC brand and Invertor model.



Kitchenarena Team

Mitsubishi Air Conditioners are really good and quite robust as they are imported directly from Japan. But, the service quality provided by them is not up to the mark in small towns. The other brands you have mentioned are also good. It is better to go with the brand that provides quick support at your place. I am listing down the top Inverter ACs with R32 Refrigerant, please have a look.
Also, have a look at this post: Best ECO Friendly ACs


Hi Chaitanya,

Please let me the answers.

Hitachi or Daiken

Invertor or without Invertor

Best model of Hitachi in May 2018 under 40000 /-

Best model of Daiken in May 2018 under 40000 /-


I stay in Bangalore I have recently purchased two 1 ton ACs. (Inverter – Split). Both Voltas. Price was not a constraint but I went by the Brand (TATAS) and also by the recommendation of the salesman.

What is your opinion about the Power consumption of these units. And also please suggest me. whether they need any power saver devices? If so suggest me a good one available in the market.



Its good to read your wonderful insights .

Please enlighten me in buying the best AC for my 200 Sq.ft bedroom

I wont be using it regularly except weekends

On daily basis will be utilizing only on nights (8hrs)

In my hometown temperatures are soaring high than ever.

PS : Need Noiseless with Efficient Operation


Hi Chaitanya ,

I am planning to buy 1.5T Samsung 3 * Inverter AC for my bedroom which is 200 sq.feet in size.

Model : AR18NV3HFWK

Please suggest that the above model is good to purchase for normal daily usage

Max Utilization on Night times (10 hrs) daily and on Weekends round the clock.

Also suggest me any good brands like bluestar or daikin to go for the same requirement.



You are really doing great help to us.

I went to buy Blue star BI-5cnhw12 PAFU, but sales guy suggest me Dakin JTKJ35tv16u based on streamer discharge technology, after booking done for Daikin i came to know that airpurifying, Ag ion and microbial filter we have to purchase on extra cost.

My question is that are these filters are good to buy or it is not needed to buy as it comes with streamer technology.

Means streamer technology is equivalent enough to cover all 7 filters of blue star AC.

Please reply ASAP. i can still convert my order to Bluestar…

Is i made good decision with Daikin Purchse?

Thanks in advance.

Kitchenarena Team

The Daikin model you have mentioned is more energy efficient model (ISEER 5.80). Also, this model comes with R-32 Refrigerant and is better than R-410A that is used in the Blue Star Air Conditioner. The Blue Star you have mentioned also comes with Dust and Anti Bacterial Filters.The Daikin Streamer technology is good and it can eliminate harmful particles like H1N1 Virus, Norovirus, Bacillus coil, influenza virus, pollen-fungal allergens. These filters are useful if you live in a dust and traffic environment.

Ashutosh Agrawal

Purchased Hitachi 5100X inverter AC. (1.5 Ton, 5 Star 2018 Rating, ISEER:4.70) a few weeks back.

The compressor was getting cut-off regularly, made a complaint to Hitachi, their service guy came and justified the cut-off of the compressor. Rated current for AC is almost 7.8Amp; it was taking 3.9 Amp before the cut-off, is it okay? I expect AC to reduce its capacity to 10% of original (i.e., current drawn should be less than 1Amp), and cut-off if it still cools more than required. Please clarify the same.

Thank you.

i need ac only in summer because of bangalore climate.

Please suggest me a good brand of ac with capacity and star rating.

thanks in advance.

Kitchenarena Team

Hi There, For your room size, 1.5 Ton AC will be good. As you are using the AC only during the Summer, 3 Star Inverter AC will be good. Hitachi, Daikin, Blue Star, Carrier, Voltas, LG Dual Inverter ACs are popular in India. Go for the brand that provides fast support at your place.


Hello Sir,

Your article has helped me know a lot about AC.

Temperature in Bangalore can go upto 40 deg Celcius. Hence I want to get an Inverter AC installed for a room of 120 sq. ft dimension. Also, if the AC has heating option to be used in Winter would help (optional)

Have heard about LG Inverter AC being good

Could you please suggest which AC is good in terms of Quality & also service? My budget is upto 45-50K



I am Kiran from Pune, I need your opinion on LG JS-Q18AUXA and LG-Q24AUXA Dual Inverter Split AC (2 Ton, 3 Star Rating, Copper).. for my 400sqft house.. Is there any better inverter ac you suggest than this

Hi Chaitanya,

Am looking to buy 1 Ton Inverter AC. Thank you for your post, i got clear explanation on AC models.

Am confused with selecting which model will suit me best,

We are leaving in Bangalore, Room size 10ft*12ft




Kitchenarena Team

All the three brand you have mentioned are Premium brands with good Refrigeration technology. With acoustic jacket on the top, Blue Star Dual Inverter Air Conditioners operate more silently. You have to go for the brand that provides good support at your place.


Hi chaitanya,

How about Samsung 8 pole Inverter AC ? In store they are mentioning this is better than other 3 brands


Hi VS, you have helped my earlier with your article on LED TVs,i finally went for Sony 772e 49inch with triluminos display which is awesome.

thanks for the wonderful article. I need to buy a 1.5 ton split full copper Inverter AC. my budget is approximately 45000 (can extend up to 10% more).

I live in Jaipur and plan on using the AC for about 8-9 hours per day for about 4 – 5 months a year. Could you please answer based on above information:

1) whether I should go for 3 star or 5 star inverter?

2) the difference in consumption of electricity (monthly) between a 3 star and 5 Star AC given my usage. Is it worth spending those extra 5000 to 7000 for a 5 Star inverter on this usage?

3) which are the top 3 brands in my budget(please rank)? I want a frank suggestion, I have been thinking about Hitachi or Mitsubishi.

4) please suggest me a few models from top brands considering the above information and your answers from the above 3 questions.

i liked these 2,your opinion on these?


Kashikoi 3300x RSB318IBEA

Kashikoi 5300x RSB518IBEA

We are looking to buy a 1.5 T AC preferably with copper condenser (as it is highly recommended in all sites).

We have hard water; not sure if this effects ACs.

Can you please advise the best of the following ACs that we should buy:




Thank you.

Kitchenarena Team

The Hitachi MR31S RSD317HBEA 3S is the better among the three models. Hard water will not have any effect on the Air Conditioner. If you live in a Corrosive environment, it is better to go with the AC that comes with corrosion protection feature.


Hi, thank you for your guidance.

We have bought the Hitachi model as recommended.

Can you please advise if this AC mandates a stabilizer?

Kitchenarena Team

“Stabilizer Free Operation” is one of the features of the Hitachi MR31S RSD317HBEA 3S Model. Also, Inverter ACs can handle voltage fluctuations better. If there are more voltage fluctuations at your place or there are sudden power surges, then it is better to put a stabilizer.


Hi, I bought a DAIKIN 3 STAR 1.8 Ton INVERTER FTKL60TV16U model AC. It states it has stabilizer free operation and operates between 160-265 volt. But in my area after 11.30 pm (night) the voltage fluctuations starts with sudden power surges (approx 110 volts it goes down) as all neighbourhood ac’s start running and it continues till 2 am, and then it rectifies… now my question is

Which stabilizer I should put and which range…because when there is dip in voltage the AC stops and starts again after a min when it gets the voltage (the salesman told me that in order to protect the PCB the AC will automatically cut when voltage goes below 160).

Thanks in advance


Many thanks for your advice.



Kitchenarena Team

Dual Inverter AC has Dual rotary motors and wider rotational frequency. The Dual Inverter ACs also works in the same ways as normal Inverter AC.


Hi Vs,

Then what’s the Beni fit of taking dual inverter over single inverter.

Suresh Sivadas


I am planning to buy an Inverter AC of 1 Ton capacity .

1)Blue Star 1 Ton 3 Star (2018) Inverter Split AC (Copper, BI-3CNHW12MAFU, White)

2)Panasonic made 1 Ton split AC – CS/CU-LU12UKYRN

3)Daikin made 1TR inverter split AC – FTKH35

4)Mitsubishi electric made inverter Split AC- MSY JP13VF

Hi Chaitanya,

First and foremost, thank you for the detailed article and information provided. I am going for 1.5ton 3star inverter AC. I’ve shortlisted HItachi MERAI 3100s RSD317HBEA and Panasonic RS18UKYL. Both of them have got similar if not the same specs in terms of ISEER ratings and price (40’000).

I live in Mumbai in a very humid area. Can you please help me in choosing in either of the 2 shortlisted AC’s that I’ve researched?

Below is the link to the product listing


Hello, I am a bit confused on purchasing inverter AC which consumes the least amount of power for my required room of 10 x 12 feet. I stay at Nagpur, on the first floor of an independent house. There is direct sunlight on the ceiling as there is no floor above it. The sunlight also falls directly on the walls from 2 sides during the day time and has a window on one of those sides. The room doesn’t cover the whole first floor area either. More than half of it is open terrace which heats up as well during the day time. Also the AC would be mostly used at the night times and at least 3 people would be sleeping there. Please help me out sir. I’m inclined towards Mitsubishi 1.6 Ton 5 Star Split AC SRK20CSS-S6 and Daikin-FTKG50TV16U.

Thanks in advance.

Kitchenarena Team

Both the models you have mentioned are good.Mitsubishi SRK 20 CSS-S6 is Quite robust product. The Daikin FTKG50TV16U with ISEER 4.7 is more energy efficient than the Mitsubishi AC and consumes less power. You can go with the brand that provides quick support at your place.

Hi Chaitanya,

The articles are neat and good. I need an information about multi split compressor AC. I am planning to install for two rooms which are about 150 sq. ft. each.

1. What are the available models in India?

2. How much would they cost approximately?

3. How efficient would they be when compared with having two individual Air conditioner?

4. What are the drawbacks?

5. What steps to be taken care while installation?


it is said that the repair and service cost of an invertor ac is much higher than the normal split ac. what would be its cost after the 1 yrs warranty period (forget the warranty of compressor)

Hi the article is really helpful, my main purpose of buying an inverter Ac is the energy consumption. While there are most of the companies that now are offering the inverter variant I’m really confused about which is the best company to go for. I have heard good reviews for Sharp 1.1 ton and Mitsubishi inverter variants I am not really sure which one should I really settle on I was looking at Voltas initially but now i’m totally confused. There are so many brands trying to voo by the various marketing strategies. My living room is 200sq ft and mainly require it for the night and afternoon for about an Hour or so.

Thanks in advance.

Hitachi, Daikin are Premium AC brands. You can go with them if they provide good service at your place. If you are living near to the sea, go for the brand that provides corrosion protection feature.


Sir my room size is 175 sq.ft, I want clarity in the refrigerator R32 and R410a which is best.. Kindly reply ASAP… Thank you sir

R32 is a better Refrigerant than R410A. R410A have Global warming potential of 2088 and R32 have 675. R32 is more environment-friendly than R410A Refrigerant. Daikin uses R32 in their Air Conditioners. You can read the full details here.

If you are Planning to use the AC during the Afternoon, it is better to go with a 1.5 Ton Air Conditioner. Both Hitachi and Daikin are premium Japanese brands. You can have a look at the below models. All of them are energy efficient.
