Using ceiling fans in your home may help cut down your energy costs; however there are a few things of which you should be aware to use your ceiling fan efficiently. Ceiling fans do not actually cool air in the room. The only reason a ceiling fan should be turned on is if there is someone in the room who will feel the benefits of the air movement.
“Ceiling fans are considered the most effective of these types of fans, because they effectively circulate the air in a room to create a draft throughout the room. If you use air conditioning, a ceiling fan will allow you to raise the thermostat setting about 4°F with no reduction in comfort… Install a fan in each room that needs to be cooled during hot weather.” When you raise the thermostat’s setting, you can save about 1 percent on your energy bills for every one degree you lower your thermostat. Over the summer, that 4 percent savings will add up.
When buying ceiling fans, be sure to look for the Energy Star label. Fans that earn the label move air on average 20% more efficiently than standard models. Be sure to check the noise ratings, and, if possible, listen to your fan in operation before you buy it.
When installing a ceiling fan, remember “ceiling fans are only appropriate in rooms with ceilings at least eight feet high. Fans work best when the blades are 7 to 9 feet above the floor and 10 to 12 inches below the ceiling. Fans should be installed so their blades are no closer than 8 inches from the ceiling and 18 inches from the walls.
“Larger ceiling fans can move more air than smaller fans. A 36- or 44-inch diameter fan will cool rooms up to 225 square feet, while fans that are 52 inches or more should be used in larger rooms. Multiple fans work best in rooms longer than 18 feet. Small and medium-sized fans will provide efficient cooling in a 4- to 6-foot diameter area, while larger fans are effective up to 10 feet.”
