Save on cooling costs this year by utilizing a ceiling fan in the rooms throughout your home. Simply installing a fan and turning it on isn't going to do the trick, though.
When the mercury climbs, be sure your fans are spinning in a counterclockwise direction to maximize cooling potential. The counterclockwise rotation creates a wind-chill effect - an actual breeze - so air conditioning can be set a little higher while you remain comfortable.
Additionally, make sure you close your exterior doors and windows tightly when the A/C is running. Making sure the weather stripping on all your doors and windows is as important during the summer as it is during the winter; keeping the cool inside while it's hot outside and vice versa in the winter keeps energy costs from skyrocketing.
When cold weather rolls around, ceiling fans can help circulate warm air by changing the fan's rotation to clockwise.
Because warm air rises, the clockwise turn of the fan picks up the air and forces it out and down. The natural circulation of the air means the warm air will rise again, and the fan will distribute the air out and down over and over again.
The clockwise rotation eliminates the breeze effect of the summer and instead creates more warmth throughout the room.
Because cooling down often means feeling a breeze, fan speeds can be medium or higher in the summer but should come down to low for the winter.
For optimal performance in any season, fan blades should be no more than 10 to 12 inches below the ceiling. If your ceilings are taller than nine feet or are vaulted, a good general rule is keep blades eight to nine feet above the floor.
