Check the filter(s) once a month and replace as necessary. Homes with pets or residents with asthma should check even more frequently. A rule of thumb is to check every month and change at least every three.
Have ductwork checked at least once a year for open joints, dust buildup, mold and rust. Open joints should be resealed with duct tape. Corroded ducts will be repaired or replaced.
Clean ductwork and registers as needed. Where there are no obvious problems, having ducts cleaned by a professional once every three years may be adequate. In dusty environments or those where occupants have pets or suffer from allergies, more frequent cleaning may prove beneficial.
Clean dust and soot from the furnace combustion chamber. Your technician will check this chamber as part of their periodic checkup. He’ll ensure that electricity and gas to the unit is turned off, and after inspecting the chamber, he’ll clean it.
Clean the blower. This is a procedure in which the HVAC technician will vacuum out the area where the blower is housed.
Inspect the blower belt (if present). Many furnaces have direct-drive blowers, but if your technician encounters a drive belt as they clean, he will inspect it for proper tension and overall condition.
