Best AC in India 2025 – Buying Guide

What is the difference between a computer and an air conditioner? A computer requires ‘Windows’ to be open for effective functioning whereas the AC needs the windows to be shut 🙂

Having begun on a lighter note, we shall dig deep and look at the various aspects that you should understand while installing air conditioners in your homes and offices.

You have different kinds of AC units. In a single-unit window AC, the compressor, condenser, and the evaporator are located in a single unit. In case of a split AC unit, you have the compressor and the condenser situated in the outdoor unit whereas the indoor unit comprises of the evaporator coils.

Size of the AC – Select the right Tonnage

Various factors go into the selection of the right size of the AC. Let us look at all of them in brief.

What is the concept of tonnage of the AC?

As you browse your way through the AC units in the market, you find the air conditioners of different tonnage such as 1-ton, 1.5-ton, 2-ton, and so on.

What does this imply?

The tonnage is the amount of heat the air conditioner removes from the room in one hour. The mathematical unit for tonnage is BTU (British Thermal Units). 1 ton equals 12000 BTU. Higher the BTU, the greater is the cooling effect.

We have just seen that the size/tonnage of the AC depends on various factors. You can also add a couple of other relative factors such as a number of occupants in the room, the amount of furniture/appliances in the room, etc.

Electricity consumption of the AC units

How much electricity does an air conditioning unit consume? This is a common question on the minds of all AC buyers. It again depends on various factors like the tonnage, star rating, and usage of the AC and so on. Let us look at some of the principal aspects in brief.

Size of the Room

The principal job of the air conditioner is to remove the heat from the room thereby making it cool. Hence, a lot depends on the size of the room. Understand that the electricity consumption of an AC unit depends on the amount of heat present in the room.

A 1.5-ton AC in a room measuring 120 sq feet will work differently as compared to the same AC in a room measuring 150 sq feet. This is because of the greater volume of hot air.

Location

Some places in India like Delhi or Nagpur become very hot in the summer months. However, the climate remains dry. On the other hand, places like Mumbai and Chennai experience a great deal of humidity.

It might not be hot but the humidity can be a draining experience. Your AC will work differently under both circumstances.

The former case requires the AC to cool down the rooms whereas the principal job of the AC in the latter instance is to remove the humidity.

Colours

This is a surprising factor, but colours do affect the performance of the AC. Darker colours absorb more heat. Hence, they take a longer time to cool. Hence, it is always better to have lighter coloured walls and curtains.

Number of people

The more the number of people in the room, the higher is the emission of heat from the bodies. Hence, you experience that you require AC units of higher tonnage to cool rooms having a higher number of people.

A 150 sq feet room in your house can work with a 1.5-ton AC whereas the room of the same size will need two 2-ton ACs in case you run a coaching class/school with say 15 to 20 kids in the room.

Electrical appliances

Just as people emit heat, so also do electrical and electronic appliances. The simple appliances like bulbs emit heat. Hence, it is beneficial to have LED lights in your room. They not only save electricity but also emit less heat.

Having a lot of furniture in the room can also increase the electrical consumption of the AC. It is better to keep your cupboards and shelves closed in an AC room. The walls absorb heat as well. Hence, insulating the walls can also help in reducing electrical consumption.

Inverter AC – Concept, Working, and Benefits

The most common term doing the rounds today is ‘Inverter AC’. What is an inverter AC? If you think that this is an AC unit that can work on the home inverters, I am afraid, you are sadly mistaken.

The home inverters have nothing to do with inverter AC. These AC units work on the Inverter Technology whereby they save a lot of power.

In a regular AC, the compressor works at full capacity when it is on. On reaching the optimum temperature, the compressor switches off and the fan continues to operate.

Once, the temperatures rise above the threshold limit, the compressor starts again and works at full capacity. This entails that the compressor works at only two speeds, full and Zero.

This is not the case with inverter ACs. These compressors work at variable speeds. In this technology, the compressor never switches off. It is always on. But, it runs at varying speeds thereby drawing less power.

It is more or less like the functioning of the accelerator in a car. As you increase the speed, you press on the accelerator. In case you want to slow down, removing the foot from the accelerator pedal is enough. The vehicle starts cruising without consuming any fuel. Thus, inverter technology is a power-saving feature available only in the split AC models.

The benefit of using inverter AC units is that they are highly energy efficient. A 3-star inverter AC is equivalent to the 5-star normal split AC. This explains the efficiency of the inverter AC vis-à-vis the non-inverter ACs.

Copper Coil vs Aluminium Coil

AC units work on the basis of compression, condensation, and evaporation. This involves moving of the refrigerant gas inside coils in gaseous as well as liquid forms. The question now arises as to which of the coils is better, copper or aluminium.

Copper has a higher heat transfer coefficient than aluminum, making it a more efficient heat exchanger. It is also significantly stronger than aluminum. Copper coils have a reputation for lasting much longer than aluminum coils, requiring fewer repairs and being easier to maintain.

Aluminium is cheaper than copper. Therefore AC units with aluminium coils are cheaper.

Corrosion

The AC works in a damp environment at all times. Hence, there is always a danger of corrosion. This corrosion results in the formation of a layer over the coils thereby affecting its conductivity. People living in humid areas near the sea should be extremely cautious about this aspect.

Blue Fin, Gold Fin, Durafin Coating

On the subject of corrosion, one must add that there are technologies available today that work towards reducing corrosion. Gold Fin+, Dura Fin and Blue Fin are the most popular Anti Corrosion coating materials.

Air conditioning Refrigerants

Normally, when you find that the AC does not deliver enough cooling, the mechanic suggests that you replace the coolant. What exactly is this coolant or the gas as they call it in many parts of the world?

Coolant is also known as the refrigerant gas and forms an important part of air conditioning and refrigeration equipment. The principal function of the air conditioning refrigerants is to absorb the heat from the room and deliver it outside. Once you eliminate heat from the room, the air in the room automatically cold. R32 is the most popular Refrigerant used in Latest Air Conditioners.

Star Ratings

Whenever you venture to buy an AC, the first thing you normally look out for the star ratings. What exactly are the star ratings?

The Bureau of Energy Efficiency, Department of Energy Savings Government of India prescribes these star ratings for various electronic products. A lot of factors go into the formulation process.

These ratings are fixed for specific periods. The latest star ratings released by BEE are from January 01, 2022, to December 31, 2025.

Understand that the 5-star AC is always going to be more expensive than the 3-star AC. However, you do save a lot in energy consumption over a long period.

Indian Seasonal Energy Efficiency Ratio (ISEER)

The concept of SEER and ISEER is the same. However, you need to consider two additional factors. A higher ISEER value indicates greater power savings.

In 2025, a 5-Star AC should have a minimum ISEER of 5, while a 3-Star AC should have a minimum ISEER of 3.8.

Cooling Seasonal Energy Consumption (CSEC): Total energy consumed by the AC when it is in active mode

Cooling Seasonal Total Load (CSTL): Total heal removed by the AC in active mode.

Now, we come to the concept of ISEER.

ISEER = CSTL/CSEC (Total amount of heat removed to the total amount of energy consumed)

The BEE makes it mandatory for Indian AC manufacturers to declare the ISEER on the star rating label.
