Why Should My Fan Rotate Differently in the Summer and Winter?

Spinning Ceiling Fan

Many people have ceiling fans in their homes to help move the air, make it more comfortable, and increase the energy efficiency of their homes. But are you using them correctly? Believe it or not, the direction your fan rotates makes a difference.

Summertime Cooling

In the summer when you want to boost the effectiveness of your air conditioner and keep yourself cooler, it’s common to flip on that ceiling fan. The important thing here is the direction it’s rotating. When you look up at the fan it should rotate in a counter-clockwise direction in the summer.

When the weather is hot we want to feel cool. A counter-clockwise rotation will blow air down on you and into the room creating a wind-chill effect. The hotter it is, the faster the fan should be moving. This makes you, and the room, feel cooler while making your air conditioner work less for the same level of comfort.

Wintertime Warmup

It might seem counterintuitive to turn on a ceiling fan when the weather is cooler, but in the winter your fan can be just as effective as in the summer, as long as it’s rotating in the right direction. As you look up at it, your fan should move in a clockwise direction.

When it’s cool outside we need an effective way to keep the warm air in our homes circulating for consistent warmth. A fan moving clockwise will help to pull the room air up and recirculate it throughout the room. Instead of blowing down which causes cooling, it will pull air up toward the ceiling, which then forces more of the warm air back down into the room. Running it at a low speed is the most effective way to keep your home comfortable.

For more effective heating in the winter and cooling in the summer, it really does matter which direction your fan blows. For more tips to increase the energy efficiency of your home contact Helms Heating and Air Conditioning by calling 877-GO-HELMS, 704-821-6255, or by clicking here.
