Ten months of heating pushes dust through your ducts
Your furnace runs from September through June here, close to ten months a year. On winter nights averaging 13°F, it cycles on and off for hours at a stretch, and every cycle pushes air through the same ductwork. Dust and the fine debris that settles in a house over a long winter get pulled in and blown back out, over and over, for most of the year.
That long stretch of steady cycling gives buildup a lot of time to collect. The more that settles inside the ducts, the less air actually reaches each room, and the furnace has to run longer to make up for it.

- How often should air ducts be cleaned?
- There is no fixed schedule that fits every home. Homes here run the furnace from September through June, so the ducts are moving air for most of the year, which gives dust and debris more chances to build up than in a place with a short heating season. If anyone in the house has allergies, or you can see dust collecting around the vents, have a contractor look sooner rather than later.
- Is air duct cleaning worth it?
- It depends on what is actually in the ducts. If a contractor finds heavy dust, pet hair, or signs that pests have gotten in, cleaning them makes a real difference to the air moving through the house. If the ducts are in decent shape already, cleaning them will not fix an unrelated heating or cooling problem. A contractor can look at the actual ductwork and tell you whether it needs it.
- What does air duct cleaning involve?
- A contractor connects a vacuum system to the ductwork and uses brushes or air tools to knock loose dust and debris, then pulls it out through the vacuum so it does not just settle somewhere else in the system. This covers the supply and return ducts, the grilles, and usually the coil and blower area too. The furnace filter is a separate part and gets checked or replaced on its own, since it is what filters the air rather than carries it.
