You are saving a lot of money this way. Considering a 50 cubic-feet-per-minute fan moves 72,000 cubic feet per day, and a 2,000 square foot home contains about 16,000 cubic feet, that's the equivalent of dumping the entire conditioned air content of your home outside 4.5 times per day. | This is the one that just works.
