Eight months of heat pushes a lot of air through your ducts
Your furnace runs October through May here. Every one of those months it is pulling air back through the same ducts, and every pass carries in dust, pet hair, and whatever else settles in the house. On nights that average 24°F, it is doing that for hours at a stretch. Most homes in the county are single-family and owner-occupied, so it is one system doing that work year after year for the people who live there.
Power loss adds to it. More than a third of households in this state went at least a day without power in 2024, and this county has seen 57 damaging wind events and 5 winter storms in the last ten years. Each time the system shuts off and starts back up, the dust sitting in the ducts gets stirred loose again. Over time that buildup can block airflow to some rooms and make the furnace work harder to push air through the rest.

- How often should air ducts be cleaned?
- Most homes do fine getting ducts cleaned every few years, though there's no fixed schedule that fits every house. If anyone in the house has allergies, or you've had renovation work that left dust behind, sooner makes sense. Homes with pets tend to need it more often too.
- Is air duct cleaning worth it?
- It depends on what's going on in your ducts. If you can see dust building up around the vents, or you're running the furnace most of the year the way homes here do from October through May, clean ducts mean the air moving through the house isn't carrying that dust into every room. It won't fix an allergy problem on its own, and it won't lower your heating bill, but it does clear buildup that a filter alone doesn't reach.
- What does air duct cleaning involve?
- A contractor uses specialized tools to loosen dust and debris from inside the ductwork, then pulls it out with a vacuum system before it can resettle. This covers the supply and return ducts, and often the grilles and registers too. The furnace or air handler may get a look as well, since dust builds up there the same way it does in the ducts.
