How to lower the cost of running a ceiling fan

Ceiling fans don't lower the room temperature; they make you feel 3–4°F cooler through wind-chill on your skin. That is why they save money only when you also raise the thermostat. A standard AC-motor fan uses 50–90W on high, while efficient DC-motor fans use 15–35W. Running a fan in an empty room just wastes electricity.

  • Turn fans off when you leave the room — they cool people, not spaces.
  • Raise the AC thermostat by 3–4°F when the fan is running.
  • In winter, reverse the direction (clockwise) on low to push warm air down from the ceiling.
  • Summers in Montana are relatively mild, so cooling costs are concentrated in a few hot weeks each year.
