ceiling fan installation and use





energy efficient ceiling fans
How well your ceiling fan performs and how much energy it will help you save depend a great deal on proper installation and use. Here are some tips offered by the US EPA to help get the most out of your appliance.
  • Read and understand the manufacturer's instructions before attempting to install a ceiling fan.

  • Be sure to use the appropriate UL-listed metal box, marked "For Use With Ceiling Fans." This outlet box is mounted above the ceiling and also is the point where the fan is attached. It houses all wiring needed to operate and connect the ceiling fan. If you are replacing a ceiling fixture, you will most likely need to replace the electrical box.

  • Anchor the ceiling fan to a ceiling joist if possible. In the case that the joist isn't located in the center of the room, a special ceiling fan mounting bracket with spiked ends should be installed between joists. Keep in mind that ceiling fans can weigh as much as 50 pounds! For tips on installing a ceiling fan, click on the file below.

  • All fan blades should be balanced prior to shipment; however, if the fan is wobbly after installation, there are ways to fix it. First, make sure that all connections are properly aligned and tightly fastened. Check the alignment of the blades by holding a yardstick vertically along the edges; you may be able to gently bend a misaligned blade holder back into proper place. If all blades are aligned, a balancing kit can then be used to pinpoint the culprit. These kits are either provided within product packaging (e.g., balancing clips and blade weights) or can be sent by the manufacturer free of charge. View a video with tips on fixing a wobbly fan.

  • Turn off when not in the room. Ceiling fans cool people, not rooms. If the room is unoccupied, turn off the ceiling fan to save energy.

  • In the summer, use the ceiling fan in the counter-clockwise direction. The airflow produced by the ceiling fan creates a wind-chill effect, making you "feel" cooler.

  • In the winter, reverse the motor and operate the ceiling fan at low speed in the clockwise direction. This produces a gentle updraft, which forces warm air near the ceiling down into the occupied space.

  • Remember to adjust your thermostat when using your ceiling fan for additional energy and dollar savings.
