It’s basic, but it’s true: If you keep the air in your house moving with a ceiling, box, or window fan, you’ll feel cooler. The simplest way to install a new ceiling fan is to substitute it for an existing ceiling fixture. Many ceiling fans also have light fixtures built into the units, so you won’t be losing your lighting. Their cost savings comes from their ability to keep a room cool without running an air conditioner all the time. Ceiling fans are an extremely effective way of cooling your home. Most ceiling fans use only about as much power as a 60 watt light bulb, which equates to around 2 cents per hour.
A reversible feature allows for the rotational direction of the fan blades to be changed at the flick of a switch. A ceiling fan can be operated in an anti-clockwise direction during winter to push warm air down your ceiling along the walls to keep the room warmer and reduce heating costs by up to 10%. In summer the fan is switched to a clockwise direction generating a cooling breeze.
