Ceiling Fan Buying Guide
Ceiling fans from the mid-1800's were powered by steam; turbines moved belts and fan blades. Philip Diehl, who invented the motor that powered the Singer Sewing Machine, used that same motor in the first two-blade electric ceiling fan in 1882. Diehl added a light kit, and competitors arrived on the scene to reap the rewards of this popular invention. By the roaring '20s, four-blade ceiling fans were the craze, then disappeared by the end of World War II, only to return again in the '50s. A few decades later, sales of ceiling fans dropped along with the prices of air conditioners.
With rising costs of fuel, the reasonable pricing of ceiling fans, and the ability of ceiling fans to lower heating and cooling expenses, the popularity of ceiling fans is soaring. By circulating warm air that rises in the winter and redistributing cool air from summer air conditioners, ceiling fans can reduce energy bills 20-30 percent. Selection of ceiling fans is based on room size, in conjunction with motor size and angle (pitch) of fan blades.

Fact: Ceiling fans mount by rod, or have hugger, slanted, or convertible mounts. Most chain-pull ceiling fans offer three speeds; wall or remote-controlled ceiling fans have up to six speeds. Greater blade pitch and higher RPMs provide more airflow. Canopies, switch housings, and outer case coverings of cheap ceiling fans are thin and often rattle or vibrate. Ceiling fans warranties cover up to 1 year - some offer limited lifetime warranties on motors.
Choosing the Right Ceiling Fan Motor
High-quality ceiling fans match motor capacities to the length of the blades. Ceiling fan selection should be based on construction and manufacturer's reputation, not warranties. Flimsy construction, unbalanced blades, and insufficient motor sizes can cause rattling and early burnout. Beware of operating ceiling fans with dimmer switches - this can damage motors and other components.
How Ceiling Fans Work
For best results, position ceiling fans at the center of the room, 8 to 10 feet above the floor, with blades 12 inches from the ceiling. If ceiling fans are placed too close to the ceiling, it is difficult for blades to grab the air and push it downward. The tilt of the fan blades determines the efficiency with which blades push the air. Major components of ceiling fans work together with heating and cooling systems to conserve energy and maximize comfort.
The Benefits of Ceiling Fans
It costs about 50 cents for every 100 hours that a ceiling fan is in operation. Look for yellow Energy Guide labels that indicate annual operating costs. Energy Guides compare the ceiling fan brand you are purchasing to other brands. Ceiling fans tagged with EnergyStar logos significantly exceeding federal energy-use standards.
