Nine months of heating pushes a lot of air through your ducts
Your furnace runs September through May here, nine months out of the year. On winter nights that average 6°F, it cycles on and off for hours at a stretch, and every cycle pushes air through the same ductwork. Whatever rides in that air, dust, dander, the fine grit that blows in around doors, settles along the way and builds up over a season that long.
Ducts carry that air into every room of the house. What has settled inside them keeps moving through the living space each time the furnace runs, and with nine months of runoff a year, that ductwork does not get much of a break to sit clean.

- How often should air ducts be cleaned?
- There's no fixed schedule that fits every home. A contractor can look at the ducts and tell you if there's a real reason to clean them, dust buildup, pest debris, mold, or a musty smell coming through the vents. Homes here run the furnace from September through May, so it's worth having the system checked before that stretch starts.
- Is air duct cleaning worth it?
- It's worth it if your ducts actually have a problem, dust buildup, pest debris, mold, or a musty smell coming through the vents. It won't lower your heating bill or fix an airflow problem caused by something else, like a clogged filter or a closed damper. A contractor can look at the ducts and tell you whether cleaning will help your specific situation.
- What does air duct cleaning involve?
- A technician connects a vacuum system to the ductwork, then uses brushes or air tools to knock loose dust and debris from inside the ducts and pull it out. They'll also clean the grilles and registers, and check the coil and blower if those are part of the job. The furnace filter isn't part of duct cleaning, that's a separate part that gets replaced on its own schedule.
