If one is looking to place an air conditioner in the room or other small places, a window air conditioner is the best option. They are designed to be fixed on the windows without taking up much space.

It is not possible for everyone because of budget constraints to buy central air conditioners so buying window air conditioners is a better idea if you are tight on budget. Also, central air conditioners require a lot more maintenance. Importantly, window air conditioners will not add excessively to your electricity bills.

There are two coils present in window air conditioners, a hot coil and a chilled coil fitted with two fans. Their purpose is to suck out the humidity and the heat present in the room by blowing air over the coils and sending it outside.

One key feature one should keep in mind before buying an air conditioner is its tonnage.
