Nine months of heating pushes a lot of air through your ducts
Your furnace runs from September through May here, nine months out of twelve. Every one of those months it's pushing air through the same ducts, over and over, and whatever is riding in that air settles out along the way. Dust, pet hair, the fine grit that comes in on boots and paws all winter. It builds up on the inside of the duct walls where the airflow can't sweep it clean.
Vermont also sees its share of power loss. Statewide, 21% of households went at least a day without power in 2024, and Addison County has logged 55 winter storms and 94 damaging wind events over the past ten years. When the power drops, the furnace stops moving air and whatever is loose in the ducts has time to settle further before the system starts back up. Over a winter with that many stops and starts, it adds up.

- How often should air ducts be cleaned?
- There's no set schedule that fits every home, so a contractor will tell you based on what they find inside your ducts. If anyone in the house has allergies, or you've had a furnace swap or renovation that left dust behind, it's worth having them looked at sooner. Homes with pets or a smoker in the house 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 at the vents, or the air coming out smells musty, cleaning them will make a real difference. If nobody in the house has breathing trouble and the system's been running fine, it may not be worth doing on a schedule. A contractor can look inside the ducts and tell you whether there's enough buildup to matter.
- What does air duct cleaning involve?
- A contractor connects a vacuum system to your ductwork and uses brushes or compressed air tools to knock loose dust and debris, then pulls it out through the vacuum. Every supply and return vent gets cleaned, along with the main trunk lines. On most jobs, the furnace or air handler gets a look too, since dust collects around the blower and coil.
