The direction a fan rotates determines whether it heats or cools a room.
The direction a ceiling fan rotates determines its effect on the perceived temperature of the room. Although ceiling fans do not change the actual temperature of a space, the breeze and air circulation can make it feel warmer or cooler.
Cooling
A ceiling fan that rotates counterclockwise makes a room feel cooler, because the blades circulate air through the room, making perspiration evaporate more quickly. This is similar to a breeze on a warm day.
Heating
A ceiling fan that rotates clockwise makes a room feel warmer. Warm air rises, and the clockwise rotation will disperse the warmer air near the ceiling throughout the room, closer to where the occupants are sitting or sleeping.
Significance
Ceiling fans cool and heat rooms at a much lower cost than a traditional heating or cooling system, particularly when used in tandem. According to the Hansen Wholesale company, a ceiling fan costs 3 cents per hour, while central air conditioning costs $1 per hour. The ceiling fan represents a significant savings.
Warning
A ceiling fan installed 6 inches or less from the ceiling will not be able to disperse air efficiently. Follow installation instructions closely when putting in a new ceiling fan.
Considerations
Not all ceiling fans are equal. The stronger and faster the blades, the more of a heating or cooling effect the fan can have. A ceiling fan with variable-speed settings can provide more control.
