Central Air Conditioners: Fan Only
Central air conditioners also have a fan-only setting. When you put the thermostat on this setting, the air conditioner wonโt run any cooling cycles. However, it will keep the air handlerโs fan running. The air handlerโs fan will circulate the air in your home. All of the air will pass through the air conditionerโs filter. This will improve your homeโs air quality, but it wonโt affect the temperature or humidity level in your home. Some people like to put their air conditioners on in this setting during the nighttime. When the central air conditioner is on the fan-only setting, it will use about 750 watts per hour no matter what its cooling capacity is. In comparison, a 42-inch ceiling fan uses about 800 watts per hour of electricity.
