Eight months of heating puts a lot of dust through your ducts
Your furnace runs October through May here, and every one of those months it is pushing air through the same ductwork. Dust, pet hair, and the fine grit that comes in on shoes and settles in carpet all get pulled into the return and pushed back out through the vents, over and over, for most of the year.
Most homes in Washington County are single-family houses people own rather than rent, and in a house you own, that buildup is yours to deal with. Winter nights averaging 14°F mean the furnace is cycling hard and often, moving more air through the ducts than it would in a milder climate. Over a season, that adds up to more dust settling in the trunk lines and more of it circulating through the rooms you live in.

- How often should air ducts be cleaned?
- There's no fixed schedule for this, it depends on what's built up inside the ducts. If anyone in the house has allergies, or you've had work done that left dust behind like a furnace swap or a remodel, it's worth doing sooner rather than later. Homes with pets or a recent water leak in the ductwork also tend to need it more often. A contractor can look inside the ducts and tell you honestly whether they need cleaning now or can wait.
- Is air duct cleaning worth it?
- It's worth it when there's a real reason for it, not just as routine maintenance. If you can see dust kicking out of the vents, if the filter is dirty again within days of changing it, or if someone in the house has unexplained allergy symptoms, cleaning the ducts can help. It won't lower your heating bills or fix a furnace that's struggling, so if that's the goal, the problem is likely somewhere else. A contractor can look at the ducts and tell you honestly whether cleaning them will make a difference in your case.
- What does air duct cleaning involve?
- A contractor connects a vacuum system to your ductwork and uses brushes or air tools to knock loose the dust and debris built up on the inside walls of the ducts, then pulls it all out through the vacuum. They'll clean the supply and return ducts, the grilles and registers, and check the furnace or air handler itself since dust collects there too. The whole system needs to be sealed properly afterward so it's not pulling in unfiltered air from the attic or basement while it runs.
