Turn off the ceiling fan, if it's running, and wait for it to stop. Position a stepladder under the ceiling fan and climb as high as you need to in order to reach the fan.
Locate the forward and reverse slide-switch control on the side of the ceiling fan.
Push the slide switch to the reverse setting so that cool air will be pulled up, and warm air close to the ceiling will be forced downward.
Start the fan and allow it to reach full speed.
Adjust the speed if it's too fast for you.
Adjust ceiling fans in other rooms so that they will also pull up cool air and force down warm air that's close to the ceiling.
Install additional ceiling fans in rooms that don't have them.
Open doors to rooms that need to be warm. Open doors from rooms where ceiling fans are running. This will facilitate warm air flow from room to room.
Close doors to rooms that are not frequently used and do not need to be heated. This will confine warm air circulation to areas that you do use.
