The most effective, say Summers, are those that face up, toward the ceilings, pushing hot air off the ceiling and more quickly cooling a room. Of course, whole-house fans can recirculate air for an entire home. They bring cool air in. A whole-house fan is like a large exhaust fan in the ceiling or attic. It sends hot air trapped in the house outside through attic vents, and draws in cool air.

Ceiling fan motor housings have been revamped, too, with streamlined, contemporary looks and more fanciful, decorative designs.
