All There Is to Know About Ceiling Fans During the Summer

Introduced in the 1800s by Thomas Edison’s contemporary, Philip Diehl, the electric ceiling fan has helped billions of people beat the heat and stay comfortable. What’s more, this practical and energy-efficient invention is still highly relevant in today’s high-tech world and in your own Yuma-area home. Read on to discover how using your ceiling fans can help prevent you and your cooling bills from overheating this summer.

What Ceiling Fans Do (and What They Don’t Do)

To get the best results when using ceiling fans, it helps to understand what these fans do and what they don’t do. Firstly, unlike your central AC or ductless mini-split, a ceiling fan does not remove heat from a room, which would act to lower a room’s temperature. A ceiling fan provides heat relief by using the windchill effect.

As the ceiling fan moves air across your skin, the air movement aids in your body’s evaporative cooling and convective cooling without lowering the cooling setting on your AC system. In fact, according to the U.S. Department of Energy’s website, by using your ceiling fan in occupied rooms, you can increase the thermostat set point 4 degrees to save energy and still feel comfortable.

Tips for Using a Ceiling Fan

A ceiling only provides relief to your energy bills if it is used correctly. Here are some important tips:

  • Occupancy. To maximize energy savings, a ceiling fan should only be used in rooms when people are present.
  • Fan placement. The windchill effect of a ceiling fan works best when the fan is positioned 7 to 9 feet above the floor. This requires a minimum ceiling height of 8 feet.
  • Blade size. While larger fan blades produce a greater windchill effect, it is advised to install a ceiling fan that is the appropriate size for the room. Always follow manufacturer guidelines for ceiling-fan selection and installation.
  • Energy Star: If you are installing a ceiling fan, select a model that carries the Energy Star rating for the greatest energy savings.
