Nine months of heat means nine months of dust through your ducts
Your furnace runs September through May here. Every one of those months, it's pulling household air through the return and pushing it back out through the same ducts, and whatever is riding in that air, dust, pet hair, the fine stuff that settles on shelves, gets pulled through too. Some of it clings to the inside of the ductwork instead of passing through.
With winter nights averaging 6°F, that furnace is working hard and running long cycles to keep up. Longer runtime means more air movement through the same ducts, more chances for buildup to collect along the way. A duct system carrying that kind of buildup can push dustier air into the house all winter.

- How often should air ducts be cleaned?
- There is no fixed schedule that fits every house, but a good marker is when dust keeps coming back fast after cleaning or someone in the house has allergies acting up more than usual. Homes here run the furnace nine months out of the year, September through May, so more air is moving through the ducts than in a place with a short heating season. A contractor can look at what has built up and tell you whether it is time.
- Is air duct cleaning worth it?
- It is worth it when there is a real reason behind it, like dust that keeps coming back, a musty smell when the air kicks on, or work that was just done on the ductwork itself. It will not fix an allergy problem on its own and it will not lower a heating bill by itself either. The value is in clearing out what has built up so the air moving through the house is cleaner, especially in a place where the furnace runs most of the year.
- What does air duct cleaning involve?
- A contractor uses a vacuum system to pull dust and debris out of the ducts, then brushes or air whips loosen anything stuck to the walls of the ductwork so it can be pulled out too. The supply and return vents get cleaned along with the main trunk lines, and the furnace blower compartment usually gets attention as well since that is where a lot of dust collects. The job is done room by room, sealing off vents that are not being worked on so dust does not get pushed into the rest of the house.
