A ceiling fan makes occupants feel cooler through air movement; it does not lower room temperature like air conditioning. ENERGY STAR advises a downward breeze in summer, a slow upward flow in winter and turning the fan off in an empty room. Check the actual model's direction control.

0 / 6 done

1. Visually check for wobble or abnormal noise; stop and seek service if anything seems loose.
2. In summer, use the manufacturer-designated direction that produces a downward cooling breeze.
3. In winter, if supported, try the reverse direction at low speed to redistribute warm ceiling air.
4. Stop the fan fully before changing direction and never touch moving blades.
5. Adjust heating or cooling settings based on comfort; a fan does not replace outdoor-air ventilation or filtration.
6. Turn the fan off when the room is unoccupied to avoid wasting electricity.
