Fans | Ceiling Fans
A ceiling fan is an electrically powered mechanical fan that is mounted on the ceiling of a space. Unlike air conditioners, fans do not change the air temperature, but instead use hub-mounted rotating blades to move the still and hot air of a room with various speeds of movement. Manually operated Punkah-type ceiling fans, originating from India, date back to 500 BC, but following the energy crisis in the late 1970s and early 1980s, ceiling fans found commercial success as an energy conservation application. Ceiling fans include an electric motor, blades, blade irons, flywheel, rotor, and a system to mount the fan unto the ceiling.
The recommended size of a ceiling fan is dependent on the size of the room. For a room up to 75 sq. ft, the maximum diameter for the fan should be 36 inches or a range between 29”-36” (73.7-91.4 cm). Up to 175 sq. ft calls for a maximum diameter of 48 inches or a range between 42” to 48” (106.7-121.9 cm).
Before attempting to balance a ceiling fan, make sure the blades are not warped. If so, they will need to be replaced. Check the screws of the mounting bracket, electrical box, and fan itself and tighten them if needed. Any bent blade can be adjusted by carefully pushing up or down on the bracket. Each blade should have the same distance from its tip to the ceiling.
To remove a ceiling fan, first determine whether the fan is down-rod mounted or bracket mounted. For both, make sure the power is off. Remove the metal cover of the mounting bracket to clearly see the ball at the top of the fan pole. Next, remove the wire nuts of the electrical connections, hold onto the light fixture and move the ball positioned at the top of the fan pole from the mounting bracket. The final step is to remove the mounting bracket from the ceiling. For a flush mounted fan, detach the blades and undo the screws that secure the fan to the ceiling bracket. Remove the fan body then the mounting bracket.
