Fans: Use and Care

Use & Care

Fan Care: Maintenance. 

When used and cared for properly, fans can help reduce the amount of energy your AC uses, or even replace it completely.

Above Board: Ceiling Fans

Use ceiling fans in rooms with ceilings at least eight feet high.1

Keep It Handy: Portables

Portable fans can be good energy savers. They cool people (not rooms) so you can move portable fans throughout the house as needed.

It’s a Breeze: Window Fans

Window fans can be effective at moving cool air into homes. Turn your window fans on in the morning and evening to circulate fresh, cool air into your living space.

Finished Fanning? Shut It Down

Fans (except window fans) work by cooling people, not rooms—so remember to turn fans off when you leave.


If you’re thinking about making efficiency improvements, the Fans Overview is a great place to get acquainted with the basics and your options, before you buy or install fans in your home.
