Ten months of heat running through the same ducts
Your furnace runs September through June here, and most nights that stretch are cold enough that it cycles on and off for hours at a time. Every cycle pushes air through the same ductwork, and dust sitting in that duct moves with it, coating the inside a little more each season.
Franklin County has seen 62 winter storms and 10 damaging wind events over the past ten years, and outages come with that kind of weather. When the power drops and the furnace stops, dust in the ducts settles instead of moving on through the vents. It builds back up the moment the system starts again. Over ten months a year, that adds up to a duct system doing a lot more work, and collecting a lot more, than one that only ran a few months out of the year.

- How often should air ducts be cleaned?
- There's no fixed schedule that fits every house. What matters more is whether anyone in the house has allergies, whether you've had a remodel or other work that left dust behind, and whether you have pets, since fur and dander build up in ductwork faster than in a home without them. A contractor can look at the ducts and tell you whether they need cleaning now or can wait.
- Is air duct cleaning worth it?
- It's worth it if your ducts actually have a buildup problem, not as something to do on a schedule regardless. Signs it's time include dust that resettles soon after you clean, musty air when the system kicks on, or visible dust coming out of the vents themselves. A contractor can look at the ductwork and tell you whether cleaning will make a real difference in your case.
- What does air duct cleaning involve?
- A contractor connects a vacuum system to the ductwork and uses brushes or air tools to loosen dust and debris from inside the duct walls, then pulls it out through the vacuum. Every supply and return vent in the house gets cleaned this way, along with the main trunk lines. The furnace or air handler itself, including the blower, often gets cleaned as part of the same visit since it's connected to the same airflow.
