Required cooling capacity

Roughly 3 tons of cooling is being estimated for a 2,700 square foot residential building. Choose 2 locations in which this estimation can be applied.

A. Rhode Island
B. Ontario, Canada
C. Nevada
D. North Carolina

AnswerA and B are the best answers. As a rule of thumb, 1 ton will cool 800-1000 sf
in the northern US and Canada, but only 450-700 sf in the southern US. Thus, 2700 sf divided by 900 sf per ton = 3 tons.
