TL;DR

A whole house fan is a ceiling mounted exhaust fan that cools your home by pulling cool outdoor air in through open windows and pushing hot indoor air out through the attic. You run it in the evening, overnight and early morning, when it is cooler outside than in, and it uses a fraction of the electricity of central air.
