Why It Matters Which Way Your Ceiling Fan Turns
Strategically changing the direction of the fan is also a great way to save money on cooling and heating costs. That's because the direction the fan is turning will dictate how the air is distributed throughout the room.
Does ceiling fan direction really matter?
The blade rotation should be set to counterclockwise for cooling, while a clockwise rotation helps to redistribute warm air during the heating season. Ceiling fans can make a huge difference as a complement to your HVAC system.
Why do you change the direction of a ceiling fan?
The airflow directly underneath the ceiling fan should push down, creating a wind-chill effect, which is going to make you feel cool. Reversing your fan, to a clockwise direction, creates a gentle updraft, recirculating heat down.
