In summer, ceiling fans should generally rotate in a counterclockwise direction. This direction creates a downdraft that pushes cool air down directly, producing a breeze that makes the room occupants feel cooler through the wind chill effect. This helps reduce reliance on air conditioning and saves energy. To confirm the direction, stand below the fan and check if you feel the breeze; if not, the fan might need its direction switched to counterclockwise for summer use.
