What direction should your ceiling fan spin during summer and winter?
Ceiling fans are a huge help in making our homes comfortable all year round. However, setting your ceiling fan to rotate in the correct direction ensures that the air is properly circulated during specific times of the year. You might notice that most ceiling fans have a switch to change the direction that the fan blades spin, either clockwise or counterclockwise. To find out what direction your ceiling fan should spin, you need to understand how airflow works.
Ceiling Fan Direction in Winter - Clockwise
For the winter months, switch your ceiling fan to run in the clockwise direction. Even though fans are generally not needed during winter, turning them on helps regulate the indoor temperature and works hand-in-hand with your thermostat.
Warm air generally accumulates near the ceiling, so the goal is to circulate that air downward and let it fill the room. Run your ceiling fan clockwise and at the lowest speed. This will push the warm air at the top downwards along the walls and all the way to the floor.
At the same time this movement displaces the cool air at the bottom and pulls it upward where the warm air used to be. Getting rid of cold spots greatly reduces heating costs and makes you more comfortable at home.
Ceiling Fan Direction in Summer - Counterclockwise
During the summer months, your ceiling fan needs to run counterclockwise. While the fan technically does not change the temperature of the air, the circulation creates a wind or breeze effect that makes the room feel cooler. This generates airflow throughout the room and produces a pleasant cooling effect. For best results, run your fan at the highest setting.
The clockwise motion creates the opposite effect of running the fan counterclockwise during winter. This time, the fan is pushing the cooler air downward to fill the room and displace the warm air. This works really well with your thermostat so you don't need to rely on air conditioning too much.
Running you ceiling fan in this direction for the hottest months of the year will lower your energy costs and keep your home from getting too hot.
Advantages of Ceiling Fans to Keep Your Home Cool
If you want to save on energy by not running your thermostat the whole day, ceiling fans are a great alternative to keep your home cool and comfortable at any time of the year. Using your ceiling fan correctly reduces both heating and cooling costs significantly. Not only do fans work indoors like in bedrooms, dining rooms, and living rooms, they are also effective outdoors like in patios and balconies.
However, leaving your fan on even when there is no one in the room is counterintuitive and defeats the purpose of saving energy and electricity. As mentioned before, fans do not change the air temperature and make it colder or hotter. They merely generate airflow and distribute the air properly to make the room more comfortable for people inside.
