Though not exactly difficult, installing a ceiling fan is not also a typical DIY task.
Unless you are very comfortable with electrical wiring, hire a certified electrician.
Ceiling Fan Size and Electrical Box
Before buying and installing a ceiling fan, consider carefully its quality and size. That’s important for energy savings.
The Lighting Association and the Energy Star program recommend the fan size showed in the table below. Also consider a UL-listed “For Use With Ceiling Fans” metal electrical outlet box (the box that houses the wiring).
Anchoring The Ceiling Fan
A ceiling fan is a heavy device that should be securely fastened to a ceiling joist or a support bracket. That’s important for safety and to ensure stability to the fan.
The Downrod Length
Ceiling fans should also be installed at a proper distance from the ceiling, floor and walls.
The blades should be at a distance of 8 inches (20 cm) or more from the ceiling, and at least at 18 inches (50 cm) from any wall. For maximum efficiency ceiling fans should also be positioned 8 to 9 feet (2.4-2.7 m) above the floor.
The downrod length can be calculated through the following formula: ceiling height (in feet) minus 9'... In other words a 12 foot/3.6 m ceiling will need a 3 foot/90 cm downrod …
New installed ceiling fans should be tightly fastened; blade holders should not be misaligned.
Ceiling fans should not wobble. You can use a fan balancing kit to balance the blades and stop the wobble. Follow the manufacturer instructions.
