Ceiling fans are more than decorative fixtures that require an occasional dusting; they can provide a whole new spin on energy savings. If used correctly, ceiling fans can help reduce your cooling and heating costs, while making you feel more comfortable.
How do ceiling fans save energy?
Ceiling fans save energy by reducing the need for air conditioning. Although they don't lower the temperature in your home, they do make it feel more comfortable. Have you ever noticed how a breeze helps you cool off on a hot day? Ceiling fans do the same thing; they create air circulation that makes your skin feel cooler, even when the room temperature remains the same.
Ceiling fans also provide an energy-efficient supplement to air conditioning systems in the occupied parts of your home. According to the U.S. Department of Energy, running a ceiling fan allows you to raise the temperature on your thermostat 4°F with no reduction in comfort. In winter, reverse the direction of the fan to draw air flow up, forcing warm air circulating near the ceiling down where you want it.
Ceiling fans do use a little bit of energy, and they only work in occupied spaces. To avoid wasting energy, turn them off when you leave a room.
Getting the most from your ceiling fans
To optimize energy savings, install ceiling fans in frequently used areas of your home, such as the family room, bedrooms and the dining room. For optimal performance, ceiling fans should be 7 to 9 feet above the floor and 10 to 12 inches from the ceiling. Locate ceiling fans as close to the center of the room as possible.
When purchasing a new ceiling fan, select a model that's ENERGY STAR®-certified. ENERGY STAR ceiling fans are more efficient than standard models.
