usually the units are sized based on the square footage of the area, and the amount of glazing.

rule of thumb = 500 to 750 s.f. per ton, depending on the ceiling heights (vaulted ceilings = 500, flat 8' ceilings = 750)

If the ground floor is 1.5X the size of the second floor, and has large expanses of windows, then the heat load is larger, requiring more tonnage
