Fort Worth/Arlington-area homeowners are always looking for ways to keep their homes cool without seeing their utility bills hit the roof. Although high-efficiency air conditioners are an excellent start, ceiling fans can greatly reduce energy use while maintaining comfort.
Ceiling fans work by moving air, not by cooling it as might be expected. Heat radiates into cooler spaces. As heat moves from your body into the air-conditioned air, the ceiling fan moves the air away from your body. New cooled air takes its place and the whole process starts over again. From a practical standpoint, this wind chill effect allows most homeowners to raise their thermostats four degrees higher without noticing a difference in their comfort level. Over the course of a summer, this reduction in energy usage can save a significant amount off your utility bills.
Ceiling fan selection and installation tips
When buying and using ceiling fans, the location of the fan and size of the room affect fan efficiency. Fans that are 36-44 inches in diameter work best in rooms that are 225 square feet or less. Larger rooms do better with fans that are 52 inches in diameter or larger. If the room is 18 feet long or longer, two fans will work better to cool the room than one.
To get the most out of a ceiling fan, you should install it between seven and nine feet from the floor. If you have high ceilings, you can buy an extension rod to bring the fan down to the correct height. Although fans work best if they are approximately one foot from the ceiling, you can install them at eight inches below the ceiling if you have a low ceiling.
Fan noise is another important factor in choosing a fan. Noise from fans is measured in sones. A quiet fan runs at about 1.5 sones, but you can find even quieter ones that run as low as 0.5 sones.
