Ceiling fans are crucial to surviving humid Minnesota summers. They provide a welcome extra breeze to keep us cool, and they shrink our monthly energy bill by giving our air-conditioning a break. Many people don’t realize ceiling fans can help regulate temperature during the winter months too.
Ceiling fans can make a room feel either cooler or warmer depending on how the blade rotation affects air currents. In the summer, your ceiling fan should rotate counterclockwise. This pushes cool air downward, producing the fan’s cooling effect.
In the winter, switch your fan to rotate clockwise. This creates an updraft that disperses the warm air collecting on your ceiling and redistributes it throughout the room.
You can adjust your rotation setting by flicking a small switch found on the base of most ceiling fans. Homeowners who use ceiling fans to circulate airflow during the winter save up to 15% on heating costs because the heat they do use warms the room more effectively.
It’s important to understand that ceiling fans don’t warm or cool the air; they warm or cool you. The idea that leaving a ceiling fan on when you leave a room will help regulate temperature while you’re going is an energy saving myth. The very opposite is true—running a fan in an empty room is a waste of energy and money.
Start taking full advantage of your ceiling fan to enjoy extra comfort and energy savings all year long.
