Ceiling Fan Settings: Clockwise or Counter Clockwise?

The Mountain Life Team Blogger May 5, 2009

With the start of May comes warmer temperates. But just because the mercury’s rising doesn’t mean your energy bills have to. 

This quick Weather Channel video shows how a ceiling fan can cool a 78-degree room by up to 6 degrees and reduce the costs of running an HVAC unit.  The key is to have the fan’s blades rotating in the right direction.

  • When the heating system is on, blades should rotate clockwise
  • When the air conditioning is on, blades should rotate counter-clockwise

By changing a ceiling fan’s blade rotation, a homeowner can push heat back into circulation to warm a room, or create a downward draft to make a room feel cooler.
