In the summer, the preferred direction for a ceiling fan to spin in is a counterclockwise direction as you look up at the fan blades. You will feel a cool downward airflow as you stand directly under the fan. In the winter, the preferred direction for a ceiling fan to spin in is a clockwise direction.
Running the fan in the reverse direction draws cooler air from near the floor and blows it toward the ceiling. At the same, the fan moves warm air trapped near the ceiling and pushes it out toward the walls and down to the floor.
