If you don’t know the accurate size then you will end up installing the wrong AC. It shouldn’t be either too large or too small. If it is too big then it can cool your room too much, the room will feel less comfortable, more power consumption, and you will have to pay more electricity bills. In case of too small a system, the unit will dry the room and the unit will have more workload.

To avoid any hassle, you can use online calculators. But use the right calculator that asks every detail of your room. It can give false results too so you must gather accurate data.


To make your room thermally efficient, the walls must be insulated.


The orientation of the room is also important. If the window is southern-faced, then it will remain cooler.
