Everyday Cheapskate: Let's Clear up the Mystery of Ceiling Fan Direction

THE SCIENCE

To make this easy, first we need to understand the principle behind moving air. You may be familiar with the terms "wind chill" and "heat index." These terms indicate what the temperature feels like, not what it is in reality on the thermometer.

 

Ceiling fans cannot reduce the temperature inside your home in the summer, but they can certainly make you feel like they do. Ditto for making you feel warmer in the winter. A ceiling fan that is set properly can make you feel as if the temperature is either cooler or warmer.

Knowing how to use fans in summer to send a rush of air downward, cooling your skin and making it seem up to eight degrees cooler than it is, lowers the chill factor.
