How Split AC’s and Window AC’s are different from each other

In this article, we have seen both the types of Air conditioners, the Split AC’s as well as the Window AC’s. But when looking for an Air conditioner the first confusion that arises is - Which type of Air conditioner is better and which one should we go for?

Well, both of these Air conditioners work on the same principle but have some different characteristics and therefore, are used at different places. So let’s see the differences

No of units

Split AC’s basically have 2 units, one is the indoor unit, and the other one is the outdoor unit. The indoor unit gives you cool air and is installed inside the room. It consists of a Capillary tube, a cooling fan, and an Evaporator. While the outdoor unit throws out the hot air and is installed outside the room. The outdoor unit consists of a Condenser, Compressor, and expansion valves.

Window ACs, on the other hand, are made up of a single unit comprising all its components.


When talking about looks Split AC’s are more aesthetically pleasing than Window AC’s and will surely enhance the look of your room.


The indoor units of Split ACs are quiet because the compressor is placed in the outdoor unit. Whereas the Window ACs are a bit noisy as the compressor is positioned in the same unit.

Energy Consumption

The energy consumption of both types of ACs with the same energy ratings is almost similar. However, Split ACs might sometimes consume a bit more electricity.


The maintenance of Split AC requires a proper technician while the maintenance of a Window AC is comparatively easy due to its compact design.


Split ACs are usually 10–20% costlier than the Window AC. Moreover, when talking about cost the brand also matters
