Nine months of heating pushes a lot of air through your ducts
Your furnace runs September through May here, close to nine months a year. Every one of those months it's pulling air through the same ducts, and whatever rides in that air settles out along the way. Dust collects along the inside walls of the duct where the airflow can't sweep it out.
With the furnace running most of the year, that buildup doesn't get much chance to settle before more is added on top of it. Ducts that stay dirty for months at a time have more surface for dust to cling to, and a return vent that's coated in it is pulling harder to move the same air through your house.

- How often should air ducts be cleaned?
- There is no fixed schedule that fits every house. Homes here run the furnace nine months out of the year, September through May, so dust and pet hair have more time to settle in the ducts than in a place with a shorter heating season. A contractor can look inside your ducts and tell you whether they need attention now or can wait.
- Is air duct cleaning worth it?
- It is worth it if the ducts are visibly dirty, if a vent has been open to a renovation, or if dust settles again soon after you clean a room. It will not lower your heating bill or fix a furnace that is not working right, so do not go into it expecting either. A contractor can look at your vents and tell you whether cleaning will actually help your air.
- What does air duct cleaning involve?
- A contractor connects a vacuum system to the ductwork, then uses brushes or air tools to knock dust and debris loose so the vacuum can pull it out. Every supply and return vent gets cleaned this way, and the furnace or air handler often gets attended to at the same time since dust collects there too. The work is done from inside the house, so nothing about your roof or siding needs to be touched.
