Ceiling fans have a switch that adjusts the spin direction of the fan blades, which can be used to keep you comfortable in both summer and winter. The switch is usually located on the side of the fan base or on an external control, like a fan remote. The direction of the fan blades affects the airflow and can create either an updraft or downdraft.

In the summer, the ceiling fan blades should rotate counterclockwise to create a downdraft that pushes air toward the floor, creating a cooling breeze. This can help keep a rooms temperature consistent throughout the day and reduce the need for an air conditioner to run constantly.

In the winter, the ceiling fan blades should rotate clockwise at a low speed to create an updraft that draws cold air up to the ceiling, displacing the warm air there and sending it down. This can help distribute and maintain heat pumped out by your furnace, allowing you to adjust your thermostat to a lower setting and save on your heating costs.

To change the direction of the fan blades, turn off the fan and let it come to a complete stop before switching the direction. For fans with pull chains, slide the reversing fan switch to the opposite direction. Using a ceiling fan in conjunction with an air conditioning unit can also help you save on air conditioning costs in your home.
