Ceiling fans and window shading

Below are frequently asked questions about household fans.

Q: Can ceiling fans reduce my air-conditioning costs?

A: Ceiling fans can lower your summertime energy costs. They create a wind chill effect by accelerating the evaporation of moisture on your skin. This wind chill effect makes you feel cooler, so you can set your thermostat at a higher temperature. Because ceiling fans cool people and not rooms, turn fans off when rooms are unoccupied.

Q: Can window shading reduce my air-conditioning costs?

A: In the summer, controlling the amount of heat that enters your home can help you reduce the cost of air conditioning by up to 25% and increase your comfort level. Windows account for nearly half of the heat gain in your home during the summer. Shade all sun-struck windows in your home with devices such as outside shade screens and awnings, and indoor draperies. The most effective shading approach is to prevent sunlight from passing through your windows into your home.
