Nine months of heat moving through the same ducts
Your furnace runs September through May here, nine months a year. On the winter nights that average 10°F, it runs long and often to keep the house warm, and all that air moving through the ducts carries dust with it.
Nine months of that is a lot more than a house somewhere warmer ever sees. The dust that settles in the ducts over a winter like this moves back into the house every time the furnace kicks on.
- 9 months
- September through May, your furnace pushes air through your ducts

- How often should air ducts be cleaned?
- There's no fixed schedule that fits every home. If anyone in the house has allergies, or you've had a renovation that left dust behind, that's a reason to clean sooner rather than wait. Pets and smokers in the house also mean the ducts collect more than average. A contractor can look inside your ducts and tell you if you're due.
- Is air duct cleaning worth it?
- It depends on what's going on in your ducts right now. If you can see dust coming out of the vents, or there's a musty smell when the furnace kicks on, cleaning solves a real problem. If your ducts look fine and nobody in the house has breathing issues, you may not need it yet. A contractor can check the ducts and tell you honestly whether cleaning will make a difference in your case.
- What does air duct cleaning involve?
- A contractor loosens the dust and debris built up inside the ductwork, then vacuums it out with a powerful vacuum system connected to the ducts. This covers the supply and return ducts, and often the grilles and registers too. Some contractors also clean the blower motor and coils if they're accessible, since dust settles there as well. The whole system gets sealed back up when the work is done.
