Is your ceiling fan spinning in the right direction this winter? In winter or summer, ceiling fans can help save energy costs by improving the comfort of your living space. Most ceiling fans will have a switch installed that will allow you choose clockwise or counterclockwise rotation.
In winter, fans should be set to turn in a clockwise rotation. This will help to redistribute the warmer air trapped at the ceiling. Cooler air below the fan will be pushed up and the warm trapped air at the ceiling will be pulled down the sides of the room improving heat distribution. This setting will also quell the “draft” and you should feel practically no air movement underneath and only a little air circulation closer to the walls.
In summer, fans should be set to run counterclockwise. This will create a breeze that will help keep you cool on hot days. The air moving over you will evaporate moisture from your skin and keep you a bit cooler. So in summer to battle the hot, stifling air in a room have the fan rotate counterclockwise blowing straight down.
