Summer vs. Winter Ceiling Fan Rotation

Do you have an existing, or looking to purchase a new ceiling fan, and wonder the purpose of having a reverse fan direction option?

Well, the forward and reverse fan rotation optimizes airflow for winter and summer seasons, therefore, creating a more comfortable living space. Let’s go into more detail.

Summer Fan Rotation

  • Forward blade direction (counter-clockwise = blue arrows)
  • Pushes air downward.
  • A ceiling fan does not cool a room like air conditioning. The rotating blades only generate a breeze over a given area, which varies based on fan blade size.
  • If a room will be unoccupied for any length of time you may want to lower the fan speed as to continue air circulation, but there is no person present that requires a stronger breeze.

Winter Fan Rotation

  • Reverse blade direction (clockwise = red arrows)
  • Pulls air upward.
  • In this reverse direction, the fan deflects the rising warm air off the ceiling, and pushes it back down.
  • Air will circulate without creating a direct, and most likely, an unwanted cool breeze.
  • NOTE: Some fan models do not have a reverse function. Check your model for availability.

Ceiling Fan Extras to Know

  • Fan direction can be confusing when looking up at the fan, as a ceiling fan appears to be moving from left to right (clockwise) for the forward direction, and vice versa. Imagine the fan mounted on a wall and the directions will become more clear.
  • Opinions may vary on airflow wants and needs (some say “use reverse fan direction” for summer to pull cool air up off the floor and “forward fan direction” in the winter season to pull hot air off the ceiling), but the default answer given by manufacturers like Casablanca, agree with the initial instructions listed.
  • Air movement will vary based on room design, ceiling height, and fan blade size.

Fan Control Options

Looking for a convenient way to control the speed and direction of your ceiling fan. Manufacturers will have their own specific series of fan controls, but there are several 3rd party options for ceiling fan wall controls, which will need to be hard wired.

If you like having apps control as much in your home as possible, you’re in luck, as there are wireless apps for ceiling fan control too.

NOTE: Not all fans and controls are compatible, or a module may need to be installed inside the fan canopy for the control to work. Carefully read fan control specifications (may be available as an online document) and installation directions before purchasing and installing.
