Clockwise Ceiling Fans
Ceiling fans are everyone's favorite summer budget-saver. But they can help out in the winter as well! Have your ceiling fans move in a clockwise direction so they push hot air along the ceiling towards the floor. If they're going counterclockwise, they won't be as effective.
Cost: free if you have a fan.
