That same cooling effect caused by blowing air currents keeps many people from using their ceiling fans in winter. But most fans have a switch that changes the direction in which the blades turn. Instead of forcing air downward, the blades will push air up toward the ceiling, where hot air normally rises, and drive it back down around the edges of the room. That can result in more even heating. And better heat circulation will help to combat the problem of sweating windows that some homes experience in the wintertime because of condensation on the glass.
Ceiling fans can help solve other cold weather problems as well.
In winter, with the furnace on, the upstairs would get hot, while the downstairs - where the thermostat is would stay cold. The furnace would run all the time. His solution was to mount a ceiling fan at the top of his stairway to help mix the air more evenly. It makes the house much more comfortable. It's another example of how - in summer and in winter fans can help you increase the comfort of your home while you decrease your monthly energy bills.
