Ceiling Fan Vs. Central Air

Ceiling fans often double as light fixtures

While central air-conditioning can have a powerful effect on the temperature of a room, many people continue to use ceiling fans to cool indoor spaces during hot summers. Both appliances have their advantages, and the right solution really depends on the homeowner's needs.

Energy Use

Central air conditioning, on average, uses 1,000 watts per room, while a ceiling fan set on high typically uses 200 to 500 watts. Ceiling fans use less electricity and therefore save money.

Room Temperature

Ceiling fans do not adjust the room temperature but instead create a cool feeling through a windchill effect. Central air actually changes the temperature in a room.

Room Size

Central air is suitable for any room size, whereas a ceiling fan is only appropriate in rooms with ceilings that are at least 8 feet tall. A room longer than 18 feet should have more than one ceiling fan.

Noise

Ceiling fans can be noisy depending on the quality of the fan. Central air makes a noise that fills the house, but the noise is not as loud as some fans can get.

Lighting

Ceiling fans sometimes include light fixtures, allowing homeowners to have two appliances in one place. Central air does not provide lighting.

Ornamentation

Central air units often appear as nothing more than white boxes, while ceiling fans come in all sorts of designs that can aesthetically enhance a home.
