Ceiling fans are an energy-efficient way to spot cool a specific room or area in your house. You may be surprised to learn that a ceiling fan does not actually cool the air, but because it improves air circulation and creates a breeze, you experience it as a wind chill/evaporative effect. In fact, most people feel just as comfortable utilizing ceiling fans even when the AC temperature is set a few degrees higher. It’s important to remember, however, that your ceiling fans must be rotating the correct direction in order for this to work. In the summer, the fan blades should rotate COUNTERCLOCKWISE so that the blades will push cooler air downwards.

Here’s what you do to enjoy that wind chill effect:

  1. Turn the fan on and stand under it to see which direction is turning.
  2. If you feel a downward breeze, then it’s moving in the right direction (counterclockwise).
  3. If not, turn off the fan and wait until it stops completely. Flip the direction switch (see fan’s instruction manual), and turn the fan back on.
  4. Increase the fan speed to medium or high for maximum cooling. Some programmable ceiling fans have the option of setting a temperature by which the fan adjusts its speed to maintain the desired wind chill temperature.
