Most homeowners use their ceiling fans in the summer to beat the heat, but a well-known fact is that ceiling fans can also be used during winter to help keep homes more comfortable and cut energy bills by up to 15%. All it takes is a simple change in the direction that the fan blades spin.
Most fans have a switch on the motor that can change the way the blades move. During the summer, it should be set to rotate counterclockwise, creating a downdraft that helps cool things off. In the winter, however, you want to flip that switch to rotate clockwise. This causes the fan to pull air upwards, which redistributes the warm air that tends to collect near the ceiling, keeping the room more evenly heated and saving you money on heating costs.
How to know if your ceiling fan is set to rotate the right way in the winter
To check if your ceiling fan is set properly, stand directly under it when it’s on high speed and test out which mode you feel the most air movement in. If you do not feel any air at all, then the switch is flipped to the winter mode.
For maximum savings, turn your ceiling fan to run clockwise at a lower speed. This will help keep your home warmer by maintaining the warm updraft created by your furnace and reducing the need for supplemental systems such as space heaters and electric blankets.
