According to Doctor HVAC, furnace maintenance should be scheduled once a year, if possible — while duct cleaning should happen every three to five years. When it comes to cleaning your furnace duct, Doctor HVAC advises homeowners to begin by covering the workspace to protect the surface.
Then remove the covers and have a look at the ductwork. You’ll then vacuum the ducts, registers, and vents. Don’t forget to disinfect the ducts and clean the blower area.
In addition to questions about cleaning the ducts and regular furnace maintenance, many wonder about cleaning their furnace filters. “One of the biggest culprits of a faulty gas furnace is a dirty filter,” Service First Heating and Cooling noted. The maintenance company explained that if you can remember to change your furnace filters every couple of months, you can avoid troublesome gas furnaces.
