Will Running Ceiling Fans All Day In Every Room Keep My Home Cooler?
Short Answer: No. Running ceiling fans all day in every room of your home will NOT keep your home cooler.
Wind Chill Factor
Ceiling fans will make you feel cooler when you stand in a room where one is running, but they don’t actually cool the air in your home. They only make you feel cooler because of the wind chill factor: by moving the air, it feels like a breeze is cooling your skin.
Don't Waste Electricity
A ceiling fan that’s running in an unoccupied room is using electricity without doing any good. Turn off your ceiling fans when you leave a room and flip them on when you come back in.
Install A Ceiling Fan In Every Room
Do install ceiling fans, especially in rooms where your family tends to congregate. A ceiling fan will allow you to raise the thermostat setting about 4 degrees with no reduction in comfort. If you tend to run on the hot side, having that nice moving air makes a world of difference in the middle of the summer.
