Things to Consider Before Buying a AC in India

Below are the things to consider before buying a ac in India.

The best air conditioner for the home is essential, as it can affect the health of the family, the comfort level, and overall energy consumption. The right air conditioning system will save money on utility bills while helping to keep the air quality in the home at its best. With technological advancement, air conditioning systems are available in many different types and brands. 

Many different features you should consider when selecting an air conditioner. This buyer’s guide will help you make an educated choice.

AC Type

In India, there are mainly two popular ACs: window ac and split ac. Let’s know about them in detail below.

Window AC: Window air conditioners are the most common type of air conditioning. They are generally installed in windows to cool the room where they are located. They work by pulling air through the unit and passing it over a refrigerant that absorbs heat. The cool air is then circulated across the room where it is installed.

Split AC: A split air conditioner is a ductless air conditioning system with an indoor unit used to cool air and an outdoor unit used to release hot air. The indoor unit has a digital display for operation, and the outdoor unit consists of a pipe and a compressor. The pipe collects all the hot air from the room, releasing it in the form of water.

Portable AC: A portable air conditioner (PAC) is the perfect solution for cooling single rooms. They are easy to install, and they can be moved from one room to another, making them a great alternative to window units and split air conditioners. 

Capacity (Tonnage)

When you want to cool a room, there are several factors you need to consider. The size of the rooms, the number of heat sources, and the ambient temperature of the region all play into how well your cooling system will work. Additionally, windows and surfaces exposed to direct sunlight can also impact the efficiency of your air conditioner. By taking all these factors into account, you can ensure that your cooling system is working as efficiently. For example, you need a 1-tonne air conditioner for a small bedroom to cool the room. In contrast, you need a 1.5-2 tonne air conditioner to cool a big or living room.

Cooling capacity

The cooling capacity of an AC depends on the size of the air conditioner. The bigger the air conditioner, the more the cooling capacity.

As the cooling capacity of the air conditioner increases, the running cost also increases. The cooling capacity of the air conditioner is measured in BTU. A BTU is calculated as the amount of energy required to raise the temperature of 1 pound of water by 1 degree.

Coil type

Aluminium: Aluminium air conditioners are less expensive compared to copper air conditioners. However, aluminium air conditioners have a lesser coefficient than their copper counterparts, making them less energy efficient.

Copper: Copper coils cool the room faster because of their effective heat transfer characteristics. They are also energy efficient, which means you will have lower power bills. However, copper coil-based air conditioners are more expensive.

Power consumption

The power consumption of an air conditioner varies based on the capacity and the energy star rating. A 1-star rating air conditioner consumes 35% more energy than a 5-star air conditioner. Similarly, a 1-tonne air conditioner consumes less power than a 1.5-tonne air conditioner. Hence, it is advisable to buy the air conditioner based on the energy ratings and the capacity needed for your room.

Compressor type

Standard: If you’re looking to save on energy costs, a standard AC is not the way to go. The compressor runs on full power until the room reaches the desired temperature and then stops working. This start-stop procedure suddenly loads the power supply and consumes more power overall. 

Inverter: If you’re looking for a more power-efficient air conditioner, an inverter AC is a way to go. However, they are more expensive than traditional ACs. There’s a common misconception that inverter ACs need a power inverter (power back up) to run, but that’s not the case. 

Inverter AC compressors are more power-efficient than non-inverter ACs because they run continuously and continuously adjust the energy consumption according to the need. Though inverter ACs might be expensive, they will cover your monthly utility bills in the long run.

Energy efficiency

The EER rating (energy efficiency rating) of an AC has been made compulsory by BEE (Bureau Of Energy Efficiency). The higher the rating, the higher the power efficiency, which means lower power consumption for cooling the room. 

After-sale service

When buying an expensive appliance like an air conditioner, it is crucial to look at the after-sale services provided by the company. Most reputed companies like LG, Samsung, and Voltas, offer an excellent after-sale service and wide coverage areas. Choosing an air conditioner from such reputable brands will help you when there is a sudden appliance breakdown.

Extended warranty

When shopping for an AC, it’s essential to look at the brand’s warranty on the compressor. The compressor is the most critical part of any AC, so you must ensure that the brand offers a reasonable warranty period. It can help protect you from expensive repairs down the road. 


These are a few crucial factors to consider when shopping for a new air conditioner. Make sure to choose one that will suit your needs and budget. You may need to make some tough decisions, but it’ll be worth it when you have the perfect AC unit for your home.
