Blower cleaning: ac, heat pumps and furnaces

Dirt in the air conditioner blower - or in the furnace or heat pump blower - will diminish the efficiency of your cooling (or heating) equipment.

A professional task

The blower compartment is often extremely tight, making cleaning and lubrication difficult. Besides, blowers are very close to line voltage, which makes its cleaning a professional job.

Cleaning procedures

A thorough cleaning may require the removing of the blower from the air handler.

Once removed, if the debris isn’t greasy, use a brush or a vacuum with a brush to clean the blower.

A more professional and deep cleaning will use pressurized water or air. In this case, protect the blower’s motor, using a taping plastic or an equivalent cover over controls and openings.
