Ceiling Fans can be a great investment in the comfort of your home; studies have shown they can keep you comfortable in temperatures as high as 86 degrees without having to use your air conditioner. During winter the ceiling fan will circulate the warm air trapped at the ceiling with the cold air at the floor by rotating the fan clockwise. Changing the direction of the fan to counter clockwise in the summer the fan will create a wind chill effect which cools our bodies by as much as 8 degrees!
Ceiling fans come in a variety of sizes, so you will want to size it according to the occupied space of the room. A good rule of thumb when sizing your fan is to divide the square footage of the occupied space by four; this will give you the diameter of the ceiling fan. If your living room equals 600sqft and the occupied space equals 200sqft, divide 200sqft by 4 equaling a 50inch fan. The ideal height of your ceiling fan should be 8 to 10 feet from the floor, so if you have a high ceiling or are installing it in your stair well, it is recommended to use a down rod for your fan.
The ceiling fan is a heavy fixture so it will need more support than a standard light fixture. The ceiling box must be fan rated and supported to the framing enough to hold at least 50lbs. - Donily Electric "Your Burnaby Electrician"
