Subscribe to our RSS Feed Your A/C and Ceiling Fans: A Dynamic Duo

Friday, May 03, 2013 is a great place to find tips for saving energy and improving home comfort. And we have another tip that can help you to do both those things this summer: Use your ceiling fans to give your air conditioning a boost.
Ceiling fans are certainly not a new idea, as they were in use many decades before air conditioning was even invented. But they are an idea that still works, and works even when you have your A/C running.

Here's how:

A ceiling fan puts the air within a room in motion, creating the equivalent of a breeze indoors. Moving the air does not make the air any colder, just like a gust of wind outdoors does not change the outside temperature. However, as we have all experienced, that sudden breeze outdoors can instantly make it feel cooler, regardless of the temperature. Meteorologists call it "wind chill," though they generally only use that term in the winter -- because the colder the air is, the bigger difference a breeze makes on how you feel.

That is also why fans actually work better now that we do have air conditioning to cool the air. The cooler air increases the wind chill effect. At room temperatures, the wind chill effect from a ceiling fan averages about four degrees; if your thermostat is set to 75 degrees, turning on the fan will make it feel like only 71 degrees.

Of course, you don't want to be too cold, so the real benefit from turning on a ceiling fan is that it allows you to turn up the thermostat. If your target temperature is 75, you can turn up the thermostat to 79 and then let your fan handle the rest. Fans use less electricity to provide that last four degrees of cooling than your A/C would, especially since you only need the fan on when someone is in the room.
