In Portland’s mild climate, your ceiling fan can do a lot to help you stay comfortable efficiently. To get the most out of your fan, keep these tips in mind:
A Little Help for Your Air Conditioner
On days that aren’t too hot, stick to using your ceiling fans for as long as you can before turning on your air conditioner. Once you do turn on the A/C, don’t turn off the ceiling fan. A ceiling fan can make you feel around 4 to 5 degrees cooler, allowing you to raise your air conditioner’s thermostat temperature by the same amount with no loss of comfort.
Every degree you raise your A/C temperature can cut your cooling bills by around 3 to 10 percent. Make sure the fan blades are set to spin counterclockwise as seen from below. Spinning in this direction, they blow a cooling breeze downward over your skin. If the blades aren’t set correctly, look for a small switch on the motor housing that lets you change their direction.
Comfort in Winter, Too
When the cool fall weather moves in, set your fan blades to spin clockwise and run the fan on the lowest speed. When spinning this way, the blades create an updraft that pulls cool air from the lower part of the room toward the ceiling. This air pushes the warm air near the ceiling out towards the walls and down to where you are. The warm air in your room will circulate around you rather than pooling near the ceiling.
Maximizing Your Fan’s Efficiency
Fans make you feel more comfortable, but they don’t change the air temperature so they don’t help when you’re not in the room. To save energy, turn off the fan when you leave the room.
To move air efficiently, your fan must be the right size for the room. For a room of less than 144 sq. ft., a 42-inch fan is enough. For a room of up to 225 sq. ft., choose a 50-inch fan.
