Best Air Conditioner in India: Buying Guide

We all know that Global warming is alarming. A couple of years back, you could easily survive with just a fan during the summer. But now, most of the cities in India are suffering from extreme heat.

best ac in india

If you stay in cities like Delhi, Mumbai, Chennai, or Kolkata, then the situation becomes worse. Extreme heat also causes so many diseases. I personally have seen people scrambled to heatstroke.

With the advancement of technology, we now have a solution to save ourselves from extreme heat. The solution is an Air Conditioner. No doubt, natural air is the best relief. But can you expect natural air in metro cities? No, then why not buy an air conditioner and give ourselves the artificial relief?

When it comes to cool and conditioning the air in your home, you want to make sure that you and your loved ones get the most efficient, environment-friendly, and cost-effective way to relax and breathe clean and quality air. Right? If yes, then you should get the Best Air Conditioner in India.

But then there are so many types of AC in the market, and there are so many options, different technical terms, all these things finally make us confused about what to buy and which one is the best.

To get rid of all these confusions, we have brought this ‘Buying Guide Of Air Conditioner.’ After reading this guide, you will have enough knowledge to decide which type of AC you should buy, how much tonnage AC you should buy, and other insights into Air Conditioners.

What Is An AC ( Air Conditioner)

As the name suggests, an AC is a machine that conditions the air. What that means is that it can remove heat or add heat to the air so that it suits your preference.

Often we have the misconception that AC produces cool air. No, AC can not produce cool air. It just takes the heat away from the air so that you feel cool. However, a blower in AC re-circulates the cool air that is already present in the room.

The whole concept of this air conditioning is called HVAC ( Heating Ventilation And Air Conditioning). However, AC’s in India does not come with a heater. But in developed countries like the USA or the UK, every AC unit comes with a heater, and that’s why the complete package is called HVAC.

How Does An AC Work?

For an AC to cool your room or your refrigerator, it needs a substance called Refrigerant. It flows through different parts of your air conditioner and takes away the heat. The process of conditioning the air is a cycle. What that means is that the flow of refrigerant is continuous until you stop it.

If you want to know more about what refrigerants are and what refrigerants are used in air conditioners, I suggest you read the below article and then come back to this article.

Must Read: What Is Refrigerant. What are the types of refrigerant used in Air Conditioners

There are mainly four processes involved in a refrigeration cycle

  • Evaporation
  • Compression
  • Condensation
  • Expansion
Refrigeration Cycle
Refrigeration Cycle


During evaporation, the refrigerant absorbs the heat from the room. While entering the evaporator, the refrigerant will be in a liquid state. But after absorbing the heat, it converts itself into a low-pressure gas.


After the evaporator, the refrigerant will get into the compressor. When the refrigerant gets into the compressor, it will be in a gaseous state. The temperature of the refrigerant will be high, and pressure will be relatively low.

The compressor increases the pressure and temperature of the refrigerant by using a compressor motor. That motor can be a non-inverter motor or an inverter motor.


The high pressure and high-temperature refrigerant gas then enter the condenser. You might have seen those black zigzag shape pipes at the back of the refrigerator. Right? Those are called condenser pipes.

In the condenser, the hot refrigerant gas dissipates heat into the atmosphere. Air conditioners use a fan for the force condensation instead of natural air. It is, therefore, preferable to keep the outdoor AC unit in such an area where sufficient airflow is available.

The condenser pipes are usually made of either aluminum or copper. Copper is the best material for cooling efficiency.


Every air conditioner has an expansion tube that reduces the pressure of the liquid refrigerant coming out of the condenser. The low-pressure, low-temperature refrigerant liquid enters the evaporation, and the cycles continue like that.

So this cycle continues like that until the room temperature goes below what you set. A thermostat detects if the temperature you set has been reached or not. After that, the compressor gets shut down for some time. Again, It starts when the temperature goes up.

This is how a refrigeration cycle works in both air conditioners and refrigerators. The only difference is that in the refrigerator, the cycle cools a small space, but it cools a room in the case of the air conditioner.

Types Of Air Conditioners

This is where most people get confused when they are buying an air conditioner. Many of them don’t know about various types of Air Conditioners, and even if they know about it, they don’t know which one is the best for them.

Here are three types of air conditioners available in the market. However, this does not include any commercial HVAC system used in offices, shopping malls, etc. The concept of commercial air conditioning is entirely different than what we use in our home.

  • Window AC
  • Split AC
  • Portable AC

Window AC

As the name suggests, Window AC is a type of AC that is fitted in the Windows. Window AC is a single-piece unit. What that means is that all the components of the air conditioner are in a single unit.

Only the blower faces the room and the rest of the components are at the back. Window AC is a great option if you are running short of space. But the problem is that you will always hear the noise of the compressor motor which is really annoying.

Window AC

Also, you need to have a dedicated space in the Window. The cooling efficiency of Window AC’s are not that great and no new technologies are developed for Windows ACs nowadays.

  • Space saving
  • No cluttered room
  • Easy repair and maintenance
  • Less service cost
  • Comparatively cheap
  • Poor cooling efficiency
  • Very noisy
  • Kind of obsolete nowadays.
  • Consume more electricity
  • Limited control options

Split AC

Some rooms do not have any space in the windows to fit an AC. Some people prefer not to block the windows, and In that case, split AC is the best option.

Split AC means that the AC unit is split into two units, One unit needs to be fitted inside the room, and the other unit needs to be fitted outside the room. The unit inside the room is called the Indoor Unit, and the one that is fitted outside is called the outdoor unit.

Split AC

The indoor unit has the blower, evaporator, and other electronic parts, and the outdoor unit has other remaining parts like compressor, condenser, etc. The indoor and outdoor unit is connected through a pipe drilled through the wall.

One of the main issues with the Split AC is that it completely messes up the look of a room if not fitted properly. You need to make a drill to connect the indoor and outdoor unit, so sometimes the drilled holes look so ugly in an otherwise well-maintained room.

You may also need to hang a voltage stabilizer which can make your room more cluttered. However, if you professionally fit everything, then everything should look good.

  • Better cooling efficiency
  • Less noise
  • Better aesthetics if fitted properly
  • New trending technologies
  • Less power consumption
  • Very costly
  • Need a piped connection for both units
  • Repair and maintenance is tough

Portable AC

If you are a bachelor or staying in a rental apartment, then portable AC is a great option. It’s similar to a Window AC where every component is in a single box. But you don’t need to fix it in a window or any wall.

Just keep the AC at any place of your house but make sure that the back of the AC is getting enough Air. These portable AC’s are similar to air coolers, but the only difference is that they can condition the air.

best ac in india

Portable AC’s are not yet very popular in India, but with the kind of mobility it offers, I am sure that portable AC’s will be in the boom in the coming years.

  • Can be placed anywhere in the room
  • Very easy to install
  • Small in size. So its portable
  • Makes a lot of noise
  • Consume more electricity

Difference Between Window AC and Split AC

Both types of AC’s are having some advantages and some disadvantages. It depends on individual preferences and requirements which one they want to choose.

For example, some people may not like to drill through their wall to fit a split AC, but they have a provision in the window to fit a window AC. In that case, the window AC is a better option.

On the other hand, if someone cares for cooling efficiency and electricity bills, they may like to split AC. However, Split AC costs way higher than a window AC. But buying an AC is a long-term investment, and everyone likes to buy the best AC.

Top 10 Things To Consider before Buying An AC

I would always suggest you go through the following things before making a purchase decision to know what you need and what you should buy.

If you buy an AC without having proper knowledge, then you may end up regretting it later. So here you go with the list of things you have to consider before you buy an AC.

1. Size Of The AC : How much Ton AC should you buy?

No, I am not talking about the physical length, width, or depth of an AC. Neither am I talking about the weight of the AC. What I meant by the size of the AC is the cooling capacity of the AC.

What Is The Tonnage Of An AC?

The cooling capacity of an AC is measured by Tonnage. It is the amount of heat the AC can remove. For example, 1 Ton AC, 1.5 Ton AC, 2 Ton AC, etc.

The measurement of heat is described as BTU ( British Thermal Unit). BTU is the amount of heat required to raise the temperature of one pound of water by 1℉

1 ton of AC can remove about 12000 BTU/ Hour. What that means is that if you buy a one-ton AC, it can remove 12000 BTU heat energy per hour from your room. If it is two-ton, then it can remove 24000 BTU / hour.

The more the tonnage of an AC, the better it is in terms of cooling efficiency. So you need to choose the perfect size of AC for getting the best cooling efficiency.

In simple words, A 1 ton of AC can cool a room up to that extent as if you kept 1 ton of ice in that room.

How to choose the right tonnage of an AC?

How much tonnage AC is right for you is purely depends on your requirement and various other factors, as shown below.

Size of the room

We already know that an AC does not supply air, but it only conditions the air. If the room size is big, the heat will be more, and the AC should be more powerful to remove that much heat.

The size of an AC is directly proportional to the size of the room. The higher the tonnage of an AC, the higher the AC’s heat removal capacity.

Often people complain that their AC is not cooling the room sufficiently, but they never think about whether they bought the right size AC or not.

For example, if you buy a 1.5 ton AC, that may be good for a 12X12 size room, but the same AC would not be sufficient for a 14X14 room.

So it’s better to check the size of your room before buying an AC. Otherwise, you will always complain about insufficient cooling.

Here is the simple chart showing the size of the AC that you need against the different sizes of the room. Please note that this is just an estimation. The actual size may vary depending upon other related factors.

Room Size (SFT-Square Feet)Recommended AC Size
Up to 80 SFT0.75 Ton
80-120 SFT1 Ton
120-180 SFT1.5 Ton
180-300 SFT2 Ton

For example, if you follow this table, for a sample 14X12 size room( 14X12=168 Sft), you should buy a 1.5 ton or a 2 ton AC.

Location Of The AC

You need to fit the AC so that it gets enough atmospheric space to dissipate the heat. If you plan to use a windows AC, make sure that there are at least 2-3 feet of space available behind the AC. Otherwise, your window AC may not cool the room properly.

If you plan to use split AC, you have the flexibility to fit the outdoor unit anywhere you want. If you’re going to fix it on the outside wall, make sure that there is enough space for air circulation. If not, you can set the outdoor unit on the roof if it’s possible.

City where you live

Well, that is something we always ignore. But it’s a fact that if you live in coastal areas like Chennai, Mumbai, or Kolkata, you need a higher tonnage AC than recommended.

The reason is simple. In coastal areas, the air gets too much moisture. Due to this, the heat dissipating capacity of the condenser gets reduced. So you need higher capacity AC for efficient cooling.

Also, when there is too much difference in outside temperature and inside temperature, the AC needs to do more work, and thus, higher tonnage AC is required. For example, In Delhi, the difference between the outside temperature and the inside temperature is too high.

To explain the scenario, let’s say you want to keep your room temperature at 25°C. Assume that the outside temperature is 50°C. After doing all the calculations, you have bought a 1.5 ton AC, which is cooling your room perfectly.

But now, if the outside temperature is increased by 80°C. Do you feel that the same AC will work? NO. You need to buy a 2 ton AC ( For example) to get the same amount of cooling that you were getting before.

Type of room

You might be wondering how the type of room can affect the AC size. But Yes, It does. For example, if you want to cool a bedroom, you may choose a lower tonnage AC, as the movement of people will be very less. You will open and shut doors and windows less frequently.

It does affect the amount of heat that can be in the room. If there is less heat in the room, you need a lower tonnage AC to cool the room.

On the other hand, if you want to fit an AC in the living room, you may need to buy a higher tonnage AC than recommended as there will be frequent movement of people. Also, you may open and shut doors and windows frequently.

Number of people in the room

We, humans, also emit heat. So the number of people in the room affects the AC size. For example, if there are 5 people in the room, a 1.5 ton AC may cool it properly.

Now in the same room, if you push 20 people, the same AC will not cool. So choose an AC based on a higher number of people going to stay at a given point of time in the room.

2. Energy Efficiency

When we talk about efficiency, it is always relative. What does that mean is that we are trying to evaluate an AC performance relative to different parameters? For example, how much heat an AC can take out per unit of power consumption.

The efficiency of a machine is the output of the machine against a set input. If the output is more at a set input, then efficiency will also be more.

BEE ( Bureau of Energy Efficiency) has made it mandatory for all AC manufacturers to show a few efficiency data and star ratings on their products to know what they are buying and how efficient their products are.

Here are those energy efficiency parameters that are in place in India.

  • EER ( Energy Efficiency Ratio)
  • SEER ( Seasonal Energy Efficiency Ratio)
  • ISEER ( Indian Seasonal Energy Efficiency Ratio)
  • CoP ( Coefficient Of Performance)
  • Star Rating

EER ( Energy Efficiency Ratio)

The energy efficiency ratio is the ratio of the amount of heat energy that the AC takes off against the amount of power.

EER= Amount Of heat energy the AC takes off/ Amount Of power it consume=(BTU/Hr)/Watt

So from the above formula, it is clear that the more the value of EER, the better the efficiency of the AC. For calculating the ERR, BEE has instructed manufacturers to assume the outside temperature as 35°C, inside temperature as 25°C, and the humidity is 50%

SEER ( Seasonal Energy Efficiency Ratio

The efficiency of an AC largely depends on the amount of work an AC does. If the temperature difference between the indoor and outdoor are too much, then the AC needs to do more work, and thus the efficiency also gets reduced.

We all know that the temperature difference is very high during the summer, and that’s why AC is less efficient. On the other hand, during the winter, AC will be more efficient as the temperature difference will be less.

EER does not consider this seasonal variation of AC efficiency. That is why the EER value may give a wrong perception of AC efficiency.

To solve this problem, SEER or Seasonal energy efficiency ratio was introduced to get the correct efficiency information. Compare to EER, and SEER just adds a factor to compensate for the seasonal efficiency fluctuation.

ISEER ( Indian Seasonal Energy Efficiency Ratio)

The concept of SEER and ISEER is the same. Only the term “Indian” was added to differentiate it for Indian weather.

The formula for calculating ISEER is the same as EER, which means that ISEER is the ratio of heat energy removed and the amount of power consumed. BEE uses different terms to explain this ratio, and here are those terms.

CoP (Coefficient Of Performance)

The coP is the ratio of the amount of cooling provided by an AC to the energy it consumes. So if the CoP is 1, then the AC will be 100% efficient.

We know that 1 KWH= 3412 BTU
1W= 3.412 BTU/Hr

Now let’s go to the formula of EER

EER= (BTU/hr)/ W= (BTU/Hr)/( 3.412 BTU/hr)= 3.412 CoP

So EER= 3.412 CoP

Star Rating

Till now, we have seen so many calculations, so many technical terms. As a general consumer, those terms will be of no use as they won’t understand all those things. Due to that reason, the Government has introduced a star rating system for refrigerators and air conditioners, which is easy to understand for consumers.

Star rating is related to the ISEER value of the AC unit. As of 2020, all AC should have the ISEER value and star rating printed on the box as per government regulation. Here is the chart showing the star rating of AC against the ISEER value range.

This circulation is valid from January 2018 to December 2019

From this table, you might have noticed that the energy efficiency is different in window AC and Split AC even if they have the same star rating.

The more the star rating value, the better the AC is in terms of electricity consumption. So a 5 star rated AC will always consume less electricity than a 4 star rated AC

Few other terms used in the energy efficiency label

Apart from ISEER, and star ratings, you may also see some of the other terms on the energy label as shown below.

BEE Star rating
BEE Star rating
Cooling Capacity ( 100%)

This shows how much cooling the AC can offer when the machine is running at 100% load. Typically the value will be the same as the amount of cooling an AC can offer based on the ISEER rating.

Cooling Capacity ( 50%)

This shows the amount of cooling that the AC can offer if the machine is running at 50% load. Usually, the cooling capacity gets down to half of the value mentioned for a 100% load.

Electricity Consumption

It shows an approximate value of the number of KwHr or the number of units of electricity the AC may consume per year. This value is based on the assumption that you are running the AC for 1600 hours per year.

Rated Cooling Capacity

This is the same as cooling capacity (100%). This is just a different term used by different manufacturers.

Maximum Cooling Capacity

This is the maximum cooling an AC can give considering +/- tolerances. For example, a 2 Ton AC can give about 2.02 or 1.98 Ton of cooling capacity considering +/- tolerances. Usually, the tolerance is +/- 5%.

Rated Power Input

This is the amount of power the AC will consume when the machine runs at 100% load. This is a critical value as based on this, and you can calculate your electricity consumption.

For example, the rated input for a 1.5 ton AC is 1500 W/Hr. Now we can calculate how many units of electricity the AC may consume if you run the AC for 8 hours a day with 100% load.

Total Power consumed per day =1500X8= 12000 W/Hr= 12000/1000 KWhr=1.2 KWhr= 1.2 Unit.

So your AC will consume about 1.2 units of electricity per day if you run it for 8 hours a day. This is just a sample calculation.

Half Power Input

This is amount of power the AC will consume if it running at 50% load

Maximum Power Input

This is the maximum power or electricity the AC will consume considering a +/- tolerance. Usually, there are about +/- 5% variations allowed by BEE.

3. Electricity Consumption Of The AC

When you buy the best AC in India, you should also look for how much electricity the AC consumes. You may have bought a feature-rich AC, but if that consumes too much electricity, then the running cost will be very high.

To save from huge, huge electricity bills, always buy 5 star AC if you want to use it for a long time. The cost of 5 stars AC is more, but it is worth the investment if you plan to keep the AC for a long time.

The electricity consumption of AC depends on various factors. Even it can vary based on different modes available in the AC. We will discuss this in this article.

How to conserve electricity with AC?

Here are few tips that may be useful to save electricity when you are running the AC

  • Always fix the AC where sufficient airflow is available
  • Keep all doors and windows closed
  • Follow the service manual to replace the refrigerant on time
  • Always keep the blower clean
  • Keep the AC vent dust-free
  • Use power-saving mode if it’s available
  • Keep fewer appliances in the room where the AC is fitted.
  • Use the auto-clean function if it’s available.

Here are some common modes available in AC’s that can help you save more electricity.

Fan Mode

In fan mode, the compressor is turned off. There is two way to activate fan mode. One is the manual mode, where you will use the AC like a fan by activating the fan mode.

The other one is automatic, where the AC will automatically activate the fan mode when the temperature reaches the threshold.

Cool mode

It’s the default mode of AC. In cool mode, AC’s will consume the optimum amount of power considering the temperature range is under the recommended value.

For example, a good temperature range is 24-27°C. If you keep your AC less than 20 degrees, then obviously, it will consume more electricity.

Turbo Mode

In turbo Mode, the AC consumes the most amount of power. So activate turbo Mode only when you need it. If you want instant cooling, then turbo Mode can help you cool up to 16-18 °C within a short time.

Dry Mode

Dry mode removes the moisture from the air. Dry Mode consumes more power. The reason is that AC is not meant for removing moisture ideally.

When you are asking AC to remove moisture, you are basically asking AC to do more work. More work means more power consumption.

Sleeping mode

If you activate the sleeping mode, the AC will increase the threshold temperature by .5 to 1 °C every hour until it 3-5 °C more than what you have set.

For example, you set the temperature at 25°C, and then you have set the sleeping mode. So after 2-3 hours, you may notice that the room temperature is 27-28 °C although you set the temperature at 25 °C.

So this increase in temperature reduces the load on AC and that saves electricity.

Power saving mode

It’s a long debate weather power saving mode really saves power or it is just a marketing trick.

During power saving mode, the AC compressors turn off automatically when the desired temperature is reached. It turns itself on when the temperature is again more than the threshold.

One may feel that this frequent Start AND Stop of the compressor may reduce electricity consumption. But it actually consumes more electricity. You can use an AC with a variable speed compressor ( Inverter AC) to save more energy.

Factor that effect the electricity consumption of AC

Here are the following factors that influence the power consumption of an AC. These factors also affect the efficiency of the AC.


If you stay in coastal areas where the air has a lot of heat and moisture, an AC needs to do more work to make your room cool. Due to that reason, your electricity consumption will be more.

Number of people in the room

If more people in the room where the AC is fitted, it will also consume more electricity. The reason is simple.

Humans emit heat energy, so if there are more people, more heat energy will be emitted, and AC needs to do more work. More work means more electricity consumption.

Paint Color of the room

You must be wondering how the paint color can affect the electricity consumption of an AC. But surprisingly, it does.

You may not know that black color can absorb more heat than white color. That is why we wear white dresses during the summer. The same logic applies to AC also.

For example, if your room’s paint color is dark, it will absorb more heat from the atmosphere, and the AC needs to do more work to cool it down. It is always preferable to use light color paint color where you want to fix your AC

Number of appliances in the room

More appliances mean more heat energy that every appliance emits. More heat energy means more work for the AC to cool it down and thus more electricity consumption.

4. Inverter AC vs Non Inverter AC

No, Inverter AC won’t work when there is a power cut. This is what people think of when they hear about inverter AC. But that is completely wrong. Inverter AC does not work like a power inverter.

Before you understand what an inverter AC is and how it works, we need to understand how a non-inverter AC works and the main pain areas.

The concept of inverter AC or non-inverter lies in the compressor motor that helps refrigerant to increase the pressure and temperature in the compressor.

best ac in india

In traditional non-inverter AC, when you start the AC, the compressor motor turns on and runs at full speed. When the temperature goes down the threshold limit, the compressor motors turn off automatically.

Now whenever the temperature goes up, the compressor motor again starts running at full speed to cool down the room.

So, in a non-inverter AC, the compressor motor runs at full speed or no speed. There is no between.

Now let me tell you what the problem is with non-inverter compressor motors. Due to the frequent start and stop of the motor, it consumes more power. Just like when you power on your mobile phone, it consumes 5-10% of the battery. Right?

Imagine you are restarting your mobile phone 50 times a day. Do you think that your phone will give good battery backup? No. Right?

That’s when the Inverter AC or Inverter Compressor motor comes to the rescue. Inverter compressor motors are variable speed motors. When you start the AC, depending on the load, it may run at full speed or may run at a slower speed. When the temperature threshold is reached, the compressor does not turn off.

Instead, it runs at a very slow speed. So in an inverter AC, the compressor never gets turn off until you turn off the AC. No problem with the start and stop of the compressor again and again. And that is why inverter AC’s offers better energy efficiency.

In a nutshell, Non-Inverter AC uses a fixed speed motor and an Inverter AC uses a variable sped motor

The next question that may come to your mind is whether the inverter AC has an inverter or battery? No, It does not. Inverter AC uses a variable speed motor powered by a variable frequency drive ( VFD). VFD can control the speed of the motor by adjusting the input frequency and voltage.

5. Condenser Coil Material : Copper Vs Aluminium

Now you might have understood the importance of condensers in an air conditioner. The condenser does the job of dissipating heat to the atmosphere. That’s an important job. Is it not?

Did you notice black zig-zag tubes at the back of your refrigerator? Those are called condenser tubes. The refrigerant flows through those tubes and dissipates heat to the atmosphere.

There are two types of metal used to fabricate those pipes. One is copper, and another one is aluminum. Copper is always the preferred choice because they offer better cooling efficiency and more ductile to create those “U” shapes.

best ac in india

Aluminum is much cheaper than copper and is used in low-cost air conditioners. They suffer the issue of corrosion, and aluminum condenser coils are not that cooling efficient. However, since aluminum is cheap, manufacturers use that for low-cost models.

One of the other issues with aluminum coils is that they are not easily repairable. If there is any leak in the aluminum condenser, then you may need to replace the whole coil.

However, in a copper condenser coil, you can use some joining methods like Soldering or Brazing to seal the leak temporarily. That saves a lot of money.

CharacteristicsCopper CoilAluminium
Cooling efficiencyBetterLess than copper
Design flexibilityGoodPoor, due to less ductility
Weight of condenserMore than aluminiumAluminium coil weights less than copper coils
DurabilityMore tough and durableNot so durable
RealiabilityMore reliable Less reliable
MaintananceEasy to maintainTough to maintain
RepairsEasy repairsNeed to replace the whole coil
CostVery HighLow

Blue Fin Technology

Blue Fin Condenser or Blue coated condenser has a special anti-corrosive coating to protect condensers from the accumulation of salt, acid, and water droplets.

blue fin technology
Blue Fin Technology

Well, Blue Fin condensers not only save condenser coils from corrosion but also helps to achieve better cooling efficiency. The life of the condenser is also greatly improved.

6. Types Of Compressor : Reciprocating Vs Rotary Compressor

A compressor is the heart of a refrigerator. The performance of air conditioners largely depends on the type of compressor and the size of the compressor. The compressor increases the temperature and pressure of refrigerant gas so that it is ready to dissipate heat while it flows through the condenser.

best ac in india

There are basically two types of compressors used in air conditioners and refrigerators.

  • Reciprocating Compressor
  • Rotating Compressor

Reciprocating Compressor

A reciprocating compressor uses a mechanism similar to an automobile engine. It has a cylinder and a piston. The piston pushes the refrigerant so that the temperature and pressure get increased.

Schematic of Reciprocating Compressor
Schematic of Reciprocating Compressor

However, the problem with reciprocating compressors is that it creates a lot of noise due to the number of moving parts in the compressors.

  • Easy maintenance
  • High pressure can be obtained
  • Relatively cheap
  • Lots of noise
  • Due to moving parts, chances of frequent breakdown

Rotary Compressor

Rotary compressors use rotor blades to suck the air. When the blades are rotating, it presses the air as the air has to escape through narrow passages. This way, the pressure and temperature of the refrigerant gets increased

rotary compressor
Schematic of Rotary Compressor
  • Produce less noise
  • Less chance of break down
  • Expensive

If you still have confusion, I would suggest you read this article to determine the differences between reciprocating and rotary compressors.

7. Types Of Coolant ( Refrigerant)

Refrigerant is the main substance that helps absorb the heat from inside the room and dissipate it to the atmosphere. During the whole process, it changes from liquid to gas and then again from gas to liquid.

It also undergoes a change in pressure and temperature during the whole process. The quality and type of refrigerant decide the cooling efficiency of an air conditioner. So if you are in the mood of buying the Best AC in India, then you should also consider the type of refrigerant that is used in your AC

There are mainly four types of refrigerant used in air conditioners.

  • Chloroflorocarbons (CFC)
  • Hydrochlorofluorocarbons – (HCFC)
  • Hydrofluorocarbons – (HFC)
  • Hydrocarbons – (HC)

 Chlorofluorocarbons -(CFC)

This is the first-ever refrigerant used in air conditioners. This refrigerant is commercially known as R12. R12 causes a serious threat to the ozone layer, and that is why it is no longer used in any refrigerator or air conditioners

Hydrochlorofluorocarbons – (HCFC)

These refrigerants are commercially known as R22. R22 is better than R12 in terms of threat to the ozone layer, but still, it has some concerns to the ozone layer. That is why R22 is phased out in many countries.

However, in India, manufacturers still use R22 in air conditioners. The Indian Government has already set a deadline to phase out R22 in the next 5-6 years.

So if you want to keep your AC for more than 5-6 years then stay away from R22 based AC’s

Hydrofluorocarbons – (HFC)

Hydrofluorocarbons are commercially available under the name R410A, R32, and R134. Typically these refrigerant does not cause any depletion to the ozone layer, and that’s why these are eco friendly.

One of the main reasons that hydrofluorocarbon does not cause any harm to the ozone layer is due to the absence of chlorine.


Hydrocarbons – (HC)

Hydrocarbon-based refrigerants are the best that is available in the market. Commercially they are available with the name R600, R600A, R290. In countries like the USA and the UK, there is pressure from governing agencies to use R600 in all refrigerators and air conditioners.

R600 comes under green refrigerants and does not cause any threat to the ozone layer. However, one of the biggest problems with R600 is that they are highly flammable. It can easily catch fire if there is a leak. So extensive research and design are required for parts to use R600.

In India, you may see air conditioners with R290. But those are damn costly. R600 based air conditioners are still a few years away. But I personally feel that we have some responsivities towards the environment and should always choose a refrigerant that is environment friendly.

Here is a list of refrigerant and their effect on Ozone Depletion Potential ( ODP) and Global Warming Potential (GWP)

RefrigerantOzone Depletion Potential (ODP)Global Warming Potential (GWP)

From the above list, it is clear that both R600A and R290 are good for the environment, and we should use those in our air conditioners in the future.

Must Read: Different Types Of Refrigerant: Choose The Best From R32 vs R410A vs R22 vs R290

8. Dehumidification

Moistures in the air cause discomfort to us. Right? Currently, many AC’s come with a feature called ” Dehumidification” that can remove the moisture from the air and cool the air.

If you are staying in coastal areas like Mumbai, Kolkata, or Chennai, you should look for an AC with a dehumidifier option. It will cost a bit more, but that will bring more comfort also.

9. Noise Label

You should always check for the noise level before you buy an AC. Split AC’s are good at the noise level. But again, there are some cheap Split AC’s that make a lot of noise.

Not only does the noise create noise pollution, but it also creates discomfort for you. When you are spending so much money buying an AC, why can’t you check the noise level for your comfort and family?

10. Brand Value And After Sales Service

When you are buying the Best AC In India, you should also check if it has a brand value or not. Also, you need to check for after-sales service. After all, AC is a machine, and every machine is prone to breakdown.

Some companies in India make very good air conditioners with a lot of advanced features. But when you go for repairs, their actual faces come into the picture. So you should always consider these aspects.

Here are some Best AC Brand / Best AC company in India

Best AC Brand / Best AC Company In India

Although numerous companies in India make AC’s, you should go with that brand that has a good presence in India, has good after-sales service, and make some good products. Based on that, here are some of the best AC brands in India.


No doubt why LG is the best AC brand in India. Not only AC but in the home appliance market, they have a good hold.

One of the areas they always excel in is innovations. You will always see some innovative features in their AC’s. Other brands follow LG. So if you buy an LG AC, I can confidently say that you won’t be disappointed.

One of the downsides of LG is that their AC’s are a bit costly. But the kind of features LG AC offers justifies the price tag. On top of that, LG AC’s are aesthetically good too.


Voltas is there in the industry for a long time. It’s a collaboration between Tata and Volkart Brothers. Voltas AC’s are known for great reliability and excellent cooling efficiency.

One of the best parts about Voltas is that their product portfolio is only into HVAC. What that means is that it only sells HVAC products. That is why they are the expert in that field and spend too much money on research and development.


Carrier is a 100 years old American Company deals in manufacturing HVAC products. Their products are extremely reliable and come with exciting new features.


Daikin is a Japanese company that has a good footfall in India. Although they don’t have any tie-up with any Indian company, they make some good AC’s.

You know that Japanese manufacturers are perfect at maintaining quality. For example, Toyota, Nissan Subaru. All are Japanese brand and has a global brand value. So you can expect good quality AC if you buy from the Daikin brand.

Blue Star

Blue Star is another great company specializing in manufacturing air conditioners. They also launch new technologies in their air conditioners, but the only downside is that Blue Star AC’s are a bit costly.


Like Daikin, Hitachi is also a Japanese company that manufactures ACs in India. Although their main business is into consumer electronics, recently, they have been more focused on appliances like air conditioners. Hitachi AC’s are full of new features and reliable too.


Whirlpool is an American brand, and in fact, they are the number one home appliances brand in the USA. In India also comes under the top 5 appliance manufacturers.

The good part about whirlpool is that their appliances are relatively cheap to buy, and they make products considering common people’s mindset.

For example, they focus more on energy saving than new features. As a common person, you want less electricity bill rather than hi-fi features. Right?

Must Have Features You Should Ask For In An AC

When we buy the Best Air AC in India, it is necessary to have some essential or must-have features apart from whatever is already mentioned in this article. Here are a few of those features that you can look for in the best AC in India.

Anti-Bacterial Filter – This Anti-Bacterial Filters can filter out the dust, pollen, bacteria, etc. and gives you pure and fresh air

Dehumidifier – This dehumidifier feature reduces the excess moisture in the air during rainy days. A must-have feature if you are staying in the coastal areas.

Heating– Although a heater can not be considered a must-have feature considering Indian weather, in places like Himachal, Sikkim, or such areas where the cold is too much, you may need a heater in your AC.

Copper Coils – The AC condenser uses coils to cool the air. Copper is more popular in the AC market with Coils because Copper has a longer life than Aluminum, Copper cools the air quickly, and Copper Coil is easy to maintain.

Auto Clean Function – Air has moisture. If it is getting accumulated for a long time, it can create corrosion on metal parts of the AC. Look for an auto-clean function in AC’s that cleans that moisture automatically.

Swing – Actually, ACs that have multi-feature swings will be able to vent cool air in every corner of the room. With these features, the room will cool quickly

Timers – While purchasing the Best AC in India, also keep in mind that it has timers. Actually, with the help of timer features you can turn the AC on and off automatically at the time set by you. It reduces the power consumption.

Coolant Leak Detection- This is an essential feature that warns us if there is a leak of refrigerant in your AC. A leak can affect the cooling efficiency of your AC, and even it can cause a fire.

Bluetooth / Wi-Fi Enabled Remote – Traditional remote works on infrared signal, and you need to be close to operating it. But with a Bluetooth remote, you can operate the AC from 10-15 meters distance. With a Wi-Fi remote, you can operate the AC anywhere where the same wi-fi network signal exists.

What Is Remotely Accessed AC

Due to New Technologies, Remotely Accessible Air Conditioner in India has become a new revolution in the market. You can control those ACs through your Smartphone.

For example, if you are coming home from Office and want your room to be cool, then just a single tap on your smartphone, and your AC is all set to run.

And as soon as you get home, your room will be completely cool. Basically, both your smartphone and AC should be connected to the internet to enable these types of features. These AC’s has smart sensors and electronic devices to recognize those commands.

Do you know in the USA, there are some AC’s that recognizes Alexa and Siri and work through voice commands

Voltage Stabilizer In AC

It is essential to have a voltage stabilizer with the Best AC in India. Nowadays, many air conditioners in India come with an inbuilt voltage stabilizer. If not, get a voltage stabilizer considering the voltage fluctuation in India.

If your Best AC in India is 0.5–0.8 tones, then a 2KVA stabilizer will be perfect Stabilizer of 3KVA is good for AC of 1.0 ton to 1.2 ton, 4KVA for AC of 1.2 to 1.6 ton, 5KVA for 2.0 to 2.5 ton AC and 6KVA for AC over 3-ton capacity.

Maintenance and Care Of AC

You should take special care and maintenance of your AC so that it last long and give you perfect cooling. You should also take special precautions while installing AC’s so that you don’t fall into any accidents. Always call professional instead of doing it yourself.

Air Conditioner Installation Tips

Always select the right place for AC installation where there is sufficient airflow and easily reachable. In case of repair, technicians should be able to reach the AC.

It’s important to put the unit (or outdoor unit for split air conditioners) under a shaded spot. The North or south side of the home is better for installation because it prevents direct sunlight on the air conditioning system.

Don’t install the outdoor unit too far from the indoor unit. A 2-3 meter distance is fine. But more than that is not recommended.

Air Conditioner Maintenance Tips

  • Make sure that you get the filters of the air conditioning cleaned before the beginning of summer. Dusty filters impact the inflow of air into the air conditioning, thereby making it work harder (consume more electricity).
  • Change the refrigerant before every summer or follow the manufacturer instructions on when to change the refrigerant
  • Check the air conditioning settings and confirm that the ‘fresh air’ vent is closed. ‘Fresh Air’ vent is employed to urge the air from the outside into the room. But as air conditioning works by cooling indoor air, opening the ‘fresh air’ vent will get more hot air from outside into space, and therefore the condenser will need to work harder to chill it.
  • Lights, computers, televisions, and every other appliance radiate heat. Confirm that these devices are packed up when not in use, else they will increase the AC load. Actually, incandescent lights (old bulbs) radiate tons of warmth and may increase units consumed by the air conditioners.
  • Maintain right insulation of the space where air conditioning is installed for effective cooling
  • Keep air conditioning at an ideal temperature of 24-25°C for the correct quantity of cooling and energy saving.
  • Don’t place lights, computers, televisions, and other light-producing devices near the air conditioning thermostat, because it will impact the right functioning of the thermostat and thereby make the air conditioning condenser work longer and consume more electricity.
  • If you’ve got an ancient air conditioning unit and regularly needs repair, it’s better to exchange it with an energy-efficient BEE star rated best ac in India. It’ll be cheaper to shop for replacement air conditioning than repairing and maintaining old air conditioning that consumes tons of electricity.

Maintaining and operating the Best AC in India can save tons of electricity and may assist you in reducing tons of your electricity bills. So do confirm that you get your Best Air Conditioner in India in the right condition before next summer.

Tips for Efficient Use of Best AC in India

  • Make the room air resistant where the AC is installed.
  • Do not lower the room temperature below 21 degrees.
  • Use AC in energy save mode.
  • Keep the windows and doors closed.
  • Do not use 1 ton AC in rooms larger than 120 SFT
  • Keep both units at a distance determined by the company.
  • Choose the AC according to the size of the room.
  • Always do servicing of your AC on time

Final Words: Best AC In India

We hope that this list of Best AC In India would help you find the best Air Conditioner for you. The air conditioner buying guide might have given you enough knowledge so that you make an informed buying decision.

However, if you still have any questions or queries, we are just a comment away. Just pen down your questions in the comment section, and we will try to resolve your query.

Frequently Asked Questions (FAQ): Best AC In India

What Is a Dual Inverter AC?

Dual Inverter AC uses similar technology to any regular Inverter AC, but it is more refined and offers better cooling efficiency. Dual Inverter AC produces less noise too.

The term ” Dual ” signifies that the dual Inverter AC is two times more energy-efficient than a single inverter AC

Which brand is the best for AC In India

If you are bothered about new technologies and features, then LG is the best. But you are looking for reliable, and cooling-efficient AC’s then brands like Blue Star, Carrier, Daikin are way better.

However, before buying any AC, Look for service availability in your area. Some brands may be good, but they have service centers only in big cities.

What is blue fin and gold fin technology?

Both bluefin and gold fin technology uses a special type of epoxy coating on top of the condenser coil. Dust, acid, or water particles do not accumulate on the surface.

It reduces the chances of corrosion, enhances cooling efficiency and longevity of condenser coils.

What Is dehumidifier in AC

The dehumidifier function removes moisture from the air. Coastal areas like Chennai, Mumbai, or Kolkata have a lot of moisture content in the air. That causes some comfort issues.

There are some AC’s that comes with a dehumidifier function that removes the moisture with the touch of a button on the AC.

Does it make sense to buy an AC with aluminum condenser?

Yes, it makes sense if it is coming with some anti-corrosion coating. It also depends on how long you want to keep your AC.

If you want to keep your AC for just a few years, it does not make sense to invest in a cooper condenser-based AC.

If your stay has less moisture throughout the year, you can also go ahead with an aluminum condenser.

But again, nowadays the cost difference between aluminum condenser-based AC and copper condenser-based AC is very less. So copper condenser makes more sense.

Which condenser is better for coastal areas?

The copper-based condenser is best for coastal areas. There are a couple of reasons for that.

Cooper does not get corrode easily
The copper condenser is more cooling efficient
The copper condenser is more energy efficient

What is the mosquito away technology is some AC’s

This is a great feature first launched by LG. No, it does not kill mosquitoes, nor it uses any chemical.

Mosquito away technology works on the principle that the AC emits some ultrasonic waves that render the mosquito’s ability to detect CO2 exhaled by a human, becomes inactive, and flies away.

What is Inverter AC?

Inverter AC uses a variable speed compressor motor, unlike non-inverter AC’s that uses a fixed speed motor. The inverter AC compressor does not shut down when the temperature threshold is reached.

Instead, it runs at a very slow speed. Since the compressor can adjust the speed based on the load, unlike other compressors that always run at full speed, inverter compressors are more energy efficient.

What is R600 Refrigerants

R600 is a kind of green refrigerant under the hydrocarbon family. R600 has zero effect on ozone layer depletion and negligible effect on global warming potential. However, R600 is highly flammable and catches fire if there is a leak.

Do I need a stabilizer for the AC?

The answer is Yes if your AC does not come with an inbuilt voltage stabilizer or your area has frequent voltage fluctuations. Otherwise, there is no need.

How many times the AC should be serviced?

Usually, once a year should be enough. But in case there is a leak, or if you feel that the AC is not cooling properly, you can get it serviced.

When we should change the refrigerant?

Once in a year that most of the manufacture s recommend, but it depends on the usage. If you use the AC more, you may need to replace refrigerant earlier than what manufacturers recommend.

How can I save energy while using an AC?

Keep all doors and windows closed while using the AC
Keep all other appliances out if the room
Use the AC between 22-27 degree centigrade
Always clean air filters regularly.
Service your AC and replace refrigerants on time.
Use light paint color in the room that has the AC
Don’t use turbo Mode unless it is really required.

How to calculate an approximate electricity bill of running an AC?

Please look into the rated power input at 100% load on your AC box.

For example, if the rated input for a 1.5 ton AC is 1500 W/Hr, we can calculate how many units of electricity the AC may consume if you run the AC for 8 hours a day with 100% load.
Total Power consumed per day =1500X8= 12000 W/Hr= 12000/1000 KWhr=1.2 KWhr= 1.2 Unit.
