Seven months of running ducts pull in a lot of dust
Your furnace runs October through April here, seven months of the year. That's seven months of air moving through the same ducts, carrying dust and whatever else settles in the return before it gets pulled through again. On the cold nights that average 30°F, the system cycles on and off often to keep up, pushing that same air through the house over and over.
Chesterfield County has also seen 9 winter storms and 138 damaging wind events over the past ten years, and a lot of households in Virginia have gone a full day or more without power. Each time a system shuts down and starts back up, whatever has settled in the ducts gets stirred loose again once the blower kicks back on.

- How often should air ducts be cleaned?
- There's no fixed schedule that fits every home. Homes with pets, a recent renovation, or someone with allergies tend to need it more often than others. If a room stays dusty even after you clean it, or you notice a smell when the system kicks on, that's a sign to have the ducts looked at rather than waiting on a calendar.
- Is air duct cleaning worth it?
- It's worth it when there's a real reason behind it, like dust that keeps coming back, a musty smell when the system runs, or ducts that were left open during construction work. It won't lower your heating bills, and it won't fix an allergy by itself. A contractor can look at the ducts and tell you whether cleaning will actually help your situation.
- What does air duct cleaning involve?
- A contractor connects a vacuum system to the ductwork, then uses brushes or air tools to knock loose dust and debris so the vacuum can pull it out. This covers the supply and return ducts, the grilles, and usually the blower compartment. The furnace filter is a separate part on its own schedule, not something that gets cleaned along with the ducts.
