Eight months of heat means eight months of dust moving through your ducts
Your furnace runs October through May here, close to eight months a year. Every time it cycles on, air pushes through the ductwork, and whatever is sitting in those ducts moves with it. Dust, drywall dust, pet hair, all of it circulates through the house every time the system kicks on.
Harrison County has seen 124 damaging wind events and 9 winter storms over the past ten years. Wind that strong works dust and debris into places it would not otherwise reach, including attic ductwork and returns near windows and doors. Add in the power outages that hit a third of West Virginia households last year, and a system that sits off for a stretch, then restarts, kicks loose whatever settled while it was down.

- How often should air ducts be cleaned?
- There's no fixed schedule that fits every house. It depends more on what's going on inside the ducts than on the calendar, so a contractor who can look inside is the one who can tell you if it's time. If anyone in the house has allergies, or you've had construction, dust or a pest problem, that's a reason to check sooner rather than wait.
- Is air duct cleaning worth it?
- It's worth doing when it's actually needed, not on a fixed schedule regardless of condition. Signs it's time include visible dust coming out of the vents, a musty smell when the furnace or AC runs, or dust that resettles on furniture soon after cleaning. A contractor can look inside the ducts 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 knock dust and debris loose, then pulls it out through the vacuum. Registers and grilles get cleaned too, and the furnace or AC coil and blower may be checked since they sit in the same airflow path. The job covers the supply and return ducts throughout the house, not just a few vents.
