Did you know that Ceiling fans are also good for the colder Months ...
They are right.
I do not think most people realize the benefits of changing the directions of your ceiling fans, based on the seasons.
In the Summer the Ceiling Fan should be rotating counter clockwise
The effects of a ceiling fan in the summer months are directly related to the well know wind chill factor. By producing a breeze or wind chill, a ceiling fans downward airflow can make a room with a thermostat setting of 78 degrees feel like 72 degrees. The actual thermostat in the room will not change, it does not cool the room, people in the room will feel the wind chill effect making them more comfortable.
In the Winter the Ceiling Fan should be rotating clockwise
Ceiling fans are generally associated with warm weather usage. However, when a ceiling fan is in the reverse motion (winter mode), the upward flow of air will push the warmer air trapped at the ceiling back down to earth making your feet feel as warm as your neck. With out a ceiling fan pushing the warm trapped air the ceiling of a room would be 15 degrees warmer than on the floor.
