Most of us know that we can use our ceiling fan to cool a room in the summer. It does this by spinning (typically) counter-clockwise to push cool air downward. However, your fan may have a switch that allows you to spin in the opposite direction to pull air upwards, which pushes the warm air that naturally rises back down.
