Ceiling Fan Savings Tips
Summers can get hot. Keeping cool is a priority, and air conditioning can make up to half of your energy usage. Ceiling fans can help you use your air conditioning less while maintaining your comfort. A central air conditioning unit typically uses around 3,500 watts of electricity while running, and running a ceiling fan on high consumes only 60 watts. That’s a drop of 98%. The strategy is to use your ceiling fans as much as you need in order to keep your AC unit running as little as possible.
How do ceiling fans work?
Ceiling fans don’t actually cool a room, but they make you feel cooler by creating a wind chill effect. A simplified explanation is that the breeze from the fan helps blow the heat away from you and speeds evaporation of sweat to help cool you. So keeping a ceiling fan running in an empty room is a complete waste of energy. Also running a ceiling fan without adjusting your thermostat a few degrees higher is double-dipping and will actually use more energy and cost you more money.
Save money in every season
Most current ceiling fans allow you to move a switch to control the direction the blades turn. For cooling in the summer the fan typically should turn counter-clockwise to blow air down creating the wind chill effect. In the winter, reverse the motor so the blades turn clockwise to create an updraft. This pushes the warmer air near the ceiling down, mixing it with the colder air below to raise the ambient temperature in the room a few degrees. Running the fan at a slower speeds in the winter is more effective for warming the room.
