What size Aircon do I need?
There are so many factors that we need to consider before we decide the correct Aircon size. 
The Main factor to determine the size of the unit is the area size and then comes other factors like how well the area is insulated, how many people normally inside and whether we have other sources of heat and how many windows we have in the room etc.
But for the main part the room size has the biggest influence on the Aircon size.
