How Many Btu Per Square Foot?

Are you feeling a bit warm, even in the winter? I'm teasing of course, if you're trying to determine how many BTU's per square feet you will need for your house or building, you will need to determine the climate of your area. Sizing your air conditioning system varies greatly on how much work it will have to do, generally speaking an A/C unit can cool 10 degrees lower than the outside .
