Nine months of heat moving through the same ducts
Your furnace runs September through May here, nine months a year. That is nine months of dust and dry air pulled through the return and pushed back out through every vent in the house. On winter nights that average 3°F, the furnace cycles on and off for hours at a stretch, and each cycle moves more of that dust through the same runs of duct.
The county has recorded 67 winter storms and 70 damaging wind events over the past ten years. Storms like that can knock out power, and when the furnace shuts down and starts back up, whatever has settled in the ducts gets stirred loose again. Over a heating season this long, that buildup lines the ducts and works its way back into the air the furnace pushes through the house.

- How often should air ducts be cleaned?
- Most homes do fine with duct cleaning every few years. Homes here run the furnace nine months out of the year, September through May, so ducts see a lot of use and collect dust faster than in a milder climate. If anyone in the house has allergies, or you just finished a remodel, moving it up makes sense.
- Is air duct cleaning worth it?
- It's worth it when there's a real reason behind it, like visible dust coming out of the vents, a musty smell when the furnace kicks on, or work done recently that left debris in the system. It won't lower your heating bills or fix a furnace that's struggling. Think of it as keeping the air moving through your house clean, not as a repair.
- What does air duct cleaning involve?
- A contractor connects a vacuum system to your ductwork and uses brushes or air tools to knock loose dust and debris, then pulls it out before it resettles. They'll usually check the vents, the returns, and the coil area near the furnace or air handler since dust collects there too. A contractor can walk you through what your specific system needs.
