Ceiling Fans
Question: Can ceiling fans lower a utility bill?
Ceiling fans can help lower your utility bill if you also increase your thermostat setting. With a ceiling fan running, you can raise the thermostat setting by 2 to 4 degrees during the cooling season with no reduction in comfort. Increasing the room temperature by even two degrees can cut your cooling costs 4 to 6 percent. Ceiling fans give the sensation that a room is cooler than it actually is because it creates a breeze. This breeze will help perspiration evaporate from your skin so that you feel cooler
Question: Should you use ceiling fans in place of air conditioning?
No. Unlike your air conditioning system, ceiling fans do nothing to lower humidity levels. When we use air conditioning, we are not only cooling the air we are also removing moisture from it. Ceiling fans are best used in conjunction with air conditioning.
Question: Is it ever appropriate to use ceiling fans alone?
Using ceiling fans alone is advisable only when the relative humidity is less than 50%.
Question: Should I leave the ceiling fan running at all times?
No, because they cool people, not rooms. Ceiling fans are less costly than air conditioning, but they still use electricity. Turn the fan on only when someone is in the room.
