Ceiling Fan winter prep tips from ‘This Old House’ star Tom Silva

Reverse ceiling fan direction. When it’s 30 degrees outside, the last thing you’re probably thinking about is your ceiling fan. But it can help you stay warm too.

Look for a small switch next to the motor of your ceiling fan that changes the blades’ direction. In the winter, set the blades to run in reverse to circulate warm air from the ceiling down into the room.

Throughout the year, Silva’s ceiling fans run continuously on low speed. In the winter, the warm air that is being pushed up from the radiators or the hot-air furnace is pushed back down. “I don’t want the fan to cool the air, I want it to move the air,” Silva explains.
