Manual J is good, but I wouldn't call it an exact answer. It uses several variables, such as number of occupants, and ceiling height. Most houses have multiple ceiling heights, and there are definite differences in the number of occupants. I would think that an over 55 community would have fewer occupants per house than other places. But, it is pretty clear that a 2000 SF house in The Villages does not need a 4 ton heat pump.
