Eight months of heating moves a lot of dust through your ducts
Your furnace runs October through May here. That is most of the year with air moving through the same ducts, and the dust in the house rides that air and settles along the way, on the inside of the duct walls and around the seams.
Winter nights averaging 26°F keep the furnace cycling on and off for months at a stretch. Every cycle pushes more air, and more dust, through the same path. Over a long heating season that buildup narrows the space air has to move through, and the furnace has to work harder to push the same heat into the room.

- How often should air ducts be cleaned?
- There's no fixed schedule that fits every house. It depends more on what's going on inside than on the calendar. Pets, a recent renovation, or someone with allergies can move up the timeline. If you can see dust building up around the vents or nobody can remember the last time they were looked at, that's a reasonable time to have them checked.
- Is air duct cleaning worth it?
- It's worth it if there's a real reason behind it, like dust that keeps coming back, a musty smell when the furnace kicks on, or work done on the ductwork itself. It won't cure allergies or lower your heating bill on its own. What it does is clear out the buildup so the air moving through your vents isn't carrying it into the rooms. A contractor can look at your ducts and tell you honestly whether cleaning them will actually help your situation.
- What does air duct cleaning involve?
- A contractor uses a vacuum system to pull dust and debris out of the ductwork, often with brushes or air tools to knock loose what's stuck to the sides. Each supply and return vent gets cleaned along with the main trunk lines. The furnace or air handler itself usually gets attention too, since dust collects there as well. The whole point is to get the buildup out of the system, not just out of sight.
