Answer by  dee68 (244)

Consider the size of the room your trying too cool first. Find out the square feet of the room then compare that with the statistical information about the air conditioner.

Depending on air conditioner type, first make sure the physical size fits with your installation area. A second size is more commonly the unit’s BTU rating which indicates how much cooling it can perform. A baseline would be 15 BTU/square foot – so a 500 sqft room would require around a 7500BTU/hour air conditioner. More complicated calculations consider aspects such as insulation, appliances, number of occupants, etc.
