During the summer, a ceiling fan will disburse cool air from the air conditioner to reduce energy costs.
Most ceiling fans are reversible to be utilized during the winter to disburse hot air from the heating system. Running the fan in reverse mode will change the direction of the blades to push down warm air from the ceiling.
For maximum efficiency and lowest energy costs, buy Energy Star ceiling fans that use up to 60 percent less energy than traditional ceiling fans.
Most ceiling fans can also be converted to light fixtures with optional installation kits. The lower use of energy reduces electric costs for lighting.
Ceiling fans range from $50 to over $1,000. The better models, usually over $250, are quiet, and the high-end models come with computer sensors that let the fan automatically change speed or direction.
