When to use fans Run fans only when someone is there to appreciate the cooling effect. During operation the fan motor generates heat energy, and energy is wasted in the space around it. Room placement Ceiling fans are usually mounted in the center of a room where the light fixture would normally go. For this reason, they often contain their own lighting fixture just below the fan blades. Lights located above the blades will appear to flicker psychedelically when the fan operates.
Some ceiling fans offer reversible operation.
The benefit is that they can blow air down in summer when the breeze will create a cooling effect, and up in winter to circulate warm air that has risen to the ceiling. This feature is particularly advantageous in rooms where high ceilings trap warm air during the heating season.
