Choosing and Using Ceiling Fans to Improve Home Comfort

According to the U.S. Environmental Protection Agency (EPA), ceiling fans allow homeowners to adjust their air conditioner thermostat up four degrees with no loss in comfort. Besides the wind chill effect such mechanical ventilation provides, moving air also helps heat escape the home.

To maximize these potential benefits, the following guidelines may help you:


  • In small rooms of four to six feet in diameter, a small or medium fan is sufficient; however, use 36- to 44-inch fans in rooms up to 10 feet, and combine multiple fans in rooms longer than 18 feet.
  • Although larger fan blades cool at slower speeds relative to smaller blades, making them a better choice for home offices or other rooms where loose papers are a constant, the smaller blades may be more aesthetically pleasing.
  • If possible, listen to the fan before purchase, and check its noise rating. More expensive ceiling fans typically operate more smoothly, resulting in a quieter, more trouble-free experience.


  • Besides common spaces such as living areas and kitchens, install ceiling fans in bedrooms and other areas that require cooling.
  • Install the fans at least eight inches below the ceiling (10 to 12 inches allows even better air circulation), seven to nine feet above the floor and at least 18 inches from walls.
  • Carefully follow the manufacturer’s instructions. Rattling or other noises during operation can result from faulty installation, reducing its value to that of cheaper models.


  • Observe the natural airflow through your home and remove obstructions such as large artificial trees or room dividers.
  • To minimize heat buildup, avoid using the oven or other heat-generating appliances as much as possible. Use sun-blocking window coverings in unshaded rooms.
