Maximize House Fan Use

How do you get the most from your house fans?

Nearly 20% of average American household’s energy expense goes toward their air conditioning bill. A cost-effective aid, even if you have air conditioning is using fans.

Tips to get the most from your fans—and energy use:


  • Ceiling fans are most effective when installed 7′ to 9′ above the
    floor and 10″ to 12″ below the ceiling.


  • Switching a ceiling fan to turn counter-clockwise pushes air toward
    ceiling will draw cool air up and move it throughout  a room.


  • Exhaust fans can provide significant cooling benefits bt removing hot/warm
    or moist air.


  • Whole house fans are powerful units that pull air in from open windows
    and push it through a home’s duct system into the rest of the house.


  • Portable fans offer the least options for cooling a house. One way to
    increase their effectiveness is to drape a wet ice-cold towel over them so
    they’re blowing cold air into a room.


  • Window fans are the most cost-effective fans —only about $15 at most stores
    and can be used in various ways to maximize their cooling potential.

– Install a window fan on a cool side of the house to increase the
air is blowing into the house to be cool.

– Use a window fan to push hot air out. This is only effective when the air
outside is cooler than inside. Instead of pointing the fan into a room, point
it outside. This works best at night.

– Use two window fans to move cool air through the house. Opening
windows and doors—particularly on opposite sides of the house—
can create ventilation.
