Best AC in India 2021 – Buying Guide

As you know that due to global warming the temperature of the Earth is increasing every year. In such a situation, it is very difficult to withstand heat in a country with a hot climate like India.

The best ACs has listed above, selected based on power consumption, warranty, price, size, technical specifications, and user reviews.

Now let’s see what you should keep in mind when buying the best AC so that your money is not wasted.

The market is filled with a wide variety of products, so buying the best AC is always challenging. In such a situation, it is very important to do market research before purchasing any product, so that you can bring happiness to your family this summer.

As everyone knows that summer is not easy, the summer season in India is also long. In such a situation, it is not easy to cook or do household work in the kitchen. Due to the heat, the person is not able to sleep properly at night.

So if central air conditioning is not an option, AC can be an inexpensive and energy-efficient option for cooling your home. But still, many questions come to our mind.

  • But which is the best ac in India to buy?
  • How to buy it?
  • What would be fine according to my room?

But first, let us see how the air conditioner works.

How Does An Air Conditioner (AC) Work?

When I was a kid, I used to think that the air conditioner is a cold air blower. But later it was discovered that nothing but AC converts hot air into cold air.

But how?

We all know that the air conditioning system keeps the house cool during the hot summer months, but do you know how it works?

An air conditioner (AC) collects warm air from your room, processes it with the help of a refrigerant and a bunch of coils, and then releases the cold air at that location. In simple terms, this is exactly how the air conditioner works.

The air conditioner mainly works on three principles.

  • Evaporator
  • Compressor
  • Condenser

Let’s check this.

In air conditioners, hot air is drawn inside the house through a vent. It contains a liquid called refrigerant which absorbs heat from the air and cools the air. It changes from liquid to gas. After that, the fan vents out the cool air.

The volume of the gas is reduced by compressing, which increases the pressure and temperature of the refrigerant and prepares it for the condensing process.

The refrigerant reaches the condenser and is exposed to the outside air. The outside air absorbs heat from the refrigerant, lowers the refrigerant temperature and changes the state from the gas back to the liquid.

After the refrigerant cools, it returns to the evaporator to repeat the process. This process continues until the temperature inside your house reaches the level you set.

Things to keep in mind when buying AC

If you keep the following things in mind when buying AC, you can easily buy the best AC in India for your family.

1. Types of air conditioners

First of all, you have to understand which types of AC you are looking for. There are different types of AC available in the market.

Windows AC (Air Conditioner)

As the name itself suggests, this unit is fitted in a slot in the wall of the room or usually in a window. Windows AC is commonly used for single rooms.

The benefit of Windows ACs

  • Economical price that split ACs
  • Easier to install
  • Doesn’t occupy internal wall space

Check the Best Windows AC in India here.

Split Air Conditioner

Split air conditioners have two parts: an indoor unit and an outdoor unit. Some components of the outdoor unit, such as compressors, condensers, and expansion valves, are installed outside the room or outside the home.

While the evaporator or cooling coil and cooling fan are installed inside the room and give cool air. You can cool one or two rooms using split air conditioners of different sizes.

Benefits of Split ACs

  • Substantial savings due to lower electricity consumption.
  • Inverter Split AC has a better energy efficiency vs non-inverter Split ACs.
  • Makes less noise as compressor and condenser are located outside.
  • Cools faster, thanks to the wide blowers that push out higher volumes of cool air.

2. Size / Capacity of the AC – How to Select the right Tonnage

The size of an air conditioner does not mean its size is large or small; rather, size refers to the cooling capacity of AC. In India, the capacity of AC is usually measured in tons.

A one-ton air conditioner is rated as 12000 BTU per hour (British thermal unit), or 3517 watts. Before purchasing AC, you can calculate the capacity required to cool a room by measuring the size of the room.

Taking care of things other than the size of the room, you can buy an AC of the right size for your home.

1. The climate of your city: The size of your AC also depends on the climate of your city. If you live in a city where the temperature reaches 42 to 45 degrees in summer, then you should buy a high capacity air conditioner. So that you can get comfortable cooling inside even if the temperature increases outside.

2. Area Method: To choose the correct size of AC by the area method, multiply the length and width of the room (in feet), now take the square-root of the answer and divide by 10. You will know how many tons of AC you need for your room.

3. Volume Method: To choose the correct size of AC by the volume method, multiply the length, width and height of a room (in feet). Divide the answer by 1000. You will know how many tons of AC you need for your room.

You also can check this AC Tonnage Calculator to calculate the size of the AC for your home.

Why choosing the right size AC is so important.

A small ton of AC will not be able to cool your room properly, even if it is running continuously. But due to continuous operation, your electricity bill will definitely increase.

In the same way, a larger ton of AC will cool your room quickly, but AC also extracts moisture from the room air, which takes longer. As the room cools, the AC has to switch off. Due to which moisture does not drain properly and you feel sticky.

There are a few factors that might require you to select a higher capacity unit.

Floor: The higher the floor of your home, the greater the cooling capacity that you will need, with the topmost floor needing the highest capacity.

Temperature: Living in a city with summer temperature consistently exceeding 40 degrees C.

Multiple Windows: If the room has multiple or large windows.

Room Orientation:

  • If the room is facing west or south.
  • If there is direct sunlight on the room
  • If more people live in the room than usual
  • If your room is located near the kitchen

Power consumption of the AC units:

Since the air conditioner is an electronic product, it will consume electricity. But how much power does the air conditioner consume? This question runs in the mind of all buyers. However, capacity, brand, AC type and use of AC determine the power consumption. Also, let’s look at a few more things.

Modes of Operation

There are many different types of modes in your AC, using which you can get the right cooling, but also save electricity. Let us see these modes.

Cool Mode

This is the default mode of AC on which AC is run to cool the room. In cool mode, you can adjust the fan speed and temperature. You can also save electricity by setting the temperature to 25-degree centigrade while using this mode.

Fan Mode

This mode is used to ventilate the room. Running the AC in fan mode saves power because in this mode the compressor is turned off, only the fan runs. Although it does not cool the room like other modes, in fact in fan mode it performs like a ceiling fan.

Dry Mode

The dry mode of AC is helpful in tropical cities or humid conditions. The dry mode is used to dissipate moisture from the air. In dry mode, the fan operates at a low speed, so using this mode saves electricity.

Heat Mode

In heat mode, you can use your AC as a heater. (This mode is of no use in summer)

Energy or Power Saver Mode

Energy or power saver mode starts working like cool mode. But in cool mode, the fan is always on, while in energy saver mode, when the temperature reaches the set limit, the fan is also turned off with the compressor. Due to which electricity is also saved.

Turbo or Quick Cool Mode

One thing I want to make clear is that this Turbo or Quick Cool mode does not save electricity. Rather, when you use this mode, running the fan at maximum speed for a maximum of 30 minutes helps to cool or warm the room. Another noticeable point is that temperature and fan settings cannot be changed when using turbo mode.

Sleep Mode

This special mode helps you save electricity while sleeping. It automatically increases the temperature by one degree every hour.

6th Sense cooling

The Whirlpool AC only has a 6th sense cooling mode that automatically adjusts the fan speed based on room temperature.

Inverter Technology

If you are searching for a smart and best AC in India that gives consistent and better cooling, along with energy-efficiency, then an inverter AC is worth investing in.

Hearing the name of inverter AC, many people start thinking about AC running on inverter. But trust me, it is not so. The inverter does not run on the inverter, instead, it runs on the inverter technology, making it extremely power saver.

What are the benefits of Inverter Air-Conditioners?

Reduced Electricity Bills

Inverter ACs consumes lesser power as the compressor does not have to frequently reach maximum cooling speeds.

Consistent Cooling

The compressor changes its speed for optimum cooling.


By having a lower load on the compressor, the lifespan of your AC is longer.

Inverter AC vs Non-Inverter AC

Which is best ac in India Inverter AC vs Non-Inverter AC?

When it comes to air conditioners, inverter technology has gained tremendous popularity in the past few years not only because it is easy to maintain and increases efficiency, but also because it cuts the electricity bill.

Let’s find the difference between inverter AC and non-inverter AC (regular AC).


It works on a variable speed compressor, which means it adjusts to a slower speed when the temperature of the room is right and speeds up when the temperature rises.

It works on a fixed speed compressor, which means it cools the room to the desired temperature and cuts off till the room gets warm again, and then it restarts.

Energy Consumption

Since it runs continuously at a variety of speeds, there is no sudden surge in the consumption of power. Since it doesn’t work at full capacity all the time, it consumes less energy.

A large amount of power is consumed every time the compressor goes on, and it’s because of this frequent on and off that this type of AC consumes more energy.


Since the compressor motor does not go on and off all the time, the operation is much quieter.

The compressor motor turns on and off throughout its operation, causing a significant amount of noise.


Cooling is even as the compressor never goes off. The room can be maintained at a constant temperature, which also facilitates good sleep.

The cooling is uneven as the compressor remains in a “power off” mode until the room warms up significantly.


It’s an expensive but long-term investment with benefits in the form of the low maintenance cost, lesser power bills, and better performance.

Comparatively cheaper, non-inverter ACs is good enough to cool a room and usually bought by those on a budget.

Copper Coil vs Aluminium Coil

Keeping yourself cool and fresh in the scorching heat is no longer difficult. Just switch on your air conditioner, cold air will freshen you up in a few moments. As you may have read in this article, the choice of the best AC depends on various factors.

Air conditioner coil is also included in this. Aluminum coils or copper coils are commonly used in air conditioners. But which coil is better for air conditioners?

Let’s look at the pros and cons of aluminum coil and copper wire so that you can pick the best AC.

Heat Transfer

The heat transfer coefficient of copper is higher than aluminum. This suggests that copper is a better heat exchanger than aluminum.


Copper is more expensive than aluminum, which definitely raises the price of air conditioners. Therefore, an air conditioner with the copper coil is expensive.


Aluminum can be easily molded into any shape because aluminum is more flexible than copper. This is why the use of aluminum in making air conditioner coils is the preferred choice of manufacturers.

Strength and Reliability

Copper is much stronger than aluminum because it spreads less under pressure. It requires less repair hence it is used more in air conditioners.


Condenser coils are always placed in external units. Due to exposure to the external environment, it requires regular cleaning so that it can work smoothly. On the other hand, aluminum coils are not strong and therefore must be placed in heavy-duty cabinets to prevent damage. This makes it difficult to clean and maintain.

Corrosion For metal tools and equipment, corrosion is nothing short of an enemy. Corrosion increases the risk of evaporator and condenser coil failure by 40% in air conditioners. Seacoasts and areas with salty water bodies and moist climates are more prone to corrosion, as air humidity is higher in such areas.

Blue Fin Condenser Technology

As I also mentioned above, corrosion has a severe effect on the condenser coil of the air conditioner. Bluefin condenser technology incorporates anti-corrosion paint on the condenser coil to avoid corrosion which ensures the efficiency and long life of the air conditioner.

Previously, this technology was used by Voltas in air conditioners, but due to its excellent results, it was also used in other brands.

Microchannel condenser coils

Microchannel condenser coils are aluminum coils with multiple flat tubes. These tubes have small channels or micro chains through which refrigerant flows. It incorporates angled and louvered fins in the middle of the flat tube to maximize heat transfer.
