Eight months of heating pushes dust through your ducts
Your furnace runs October through May here, eight months out of the year. Every time it fires, air moves through the ducts, and whatever has settled in them gets pushed into the rooms you're heating. With winter nights averaging 23°F, the furnace is cycling on and off often to keep up, and each cycle stirs up more of what's sitting in the bends and low points of the duct run.
Dust that keeps moving through the system also settles back into it, and ducts carrying less clean air make the furnace work harder to heat the same rooms.

- 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 just finished a remodel that kicked up dust and drywall grit, that's a reason to clean sooner rather than later. Ducts that stay dry and sit behind a filter changed regularly don't collect much in between. A contractor who looks inside the ductwork can tell you what yours actually needs.
- Is air duct cleaning worth it?
- It depends on what's actually in your ducts. If you can see dust blowing out of the vents, or you pull the filter and it's caked after just a few weeks, cleaning will help. If the ducts are just carrying normal household dust and the filter looks fine, you likely won't notice much difference. A contractor can look at the actual ductwork and tell you whether it needs it.
- What does air duct cleaning involve?
- A contractor hooks up a vacuum system to the ductwork and uses brushes or air whips to knock dust and debris off the inside walls of the ducts, then pulls it all out through the vacuum. Every supply and return vent gets cleaned, along with the main trunk lines. The furnace blower and coil often get cleaned at the same time since they sit in the same air path.
