How to choose between window and split AC?

We have reviewed both window ACs as well as split ACs. Before you choose any air conditioner, there are a few points you should consider:

The number of units:

A window AC is made up of one single unit. Usually, it is placed in a cavity with a part of it facing outside while the other part faces inside. 

On the other hand, split AC contains two units. One is the outdoor unit consisting of expansion valves, compressor, and condenser. This unit is situated outside your room and is connected to the indoor unit manually. It works on pushing the air to the outside.

The indoor unit is the unit you fix in your room. It consists of an evaporator, cooling fan, and capillary tube. This unit works to cool the air in your room.


A split AC fares much better than a window AC in terms of looks. They are sleek and stylish and usually located at the upper portion of the wall. Window ACs usually appear bulky since they comprise one single large unit.


Window ACs are noisier than split ACs. This is because the outdoor part of the window AC is connected to the indoor part. Since all the components are in a single place, you can constantly hear the noise. 

Split ACs on the other hand are more silent. The noise that the outdoor component makes can’t be heard inside your room. This can make the overall experience more peaceful and calm.

Energy consumption:

Though sometimes split ACs consume more energy, usually the energy consumption is dependent on the energy star rating, tonnage, and ISEER value. So, for ACs with similar values, the energy consumption is also similar.


Due to the two components in a split AC, the maintenance requires a skilled professional. Whereas, due to the compact design of a window AC, it requires low maintenance.


Usually split ACs cost more than window ACs. But, you should also take into consideration the brand of the AC as the cost can vary from brand to brand.



We have seen the six best products from three different brands. When choosing an AC, the star rating, tonnage as well as different other factors are needed to be considered.

Each brand has its own advantages as well as disadvantages. We hope that by reading about each air conditioner in detail, you can find an air conditioner that you love!
