Seven months of heating pushes air through the same ducts
Your furnace runs from October through April here, seven months out of the year. On the cold nights in between, the kind that average 28°F from December through February, that system is moving air through the ductwork for hours at a stretch. Whatever is sitting in those ducts gets pushed into every room that long.
Dover has also had its share of storms, 10 winter storms and 120 damaging wind events over the past ten years. Power interruptions come with that, and about 12% of Delaware households lost power for a day or more in 2024. When a system shuts down and starts back up, it stirs up what has settled in the ducts instead of carrying it along steadily. Over years of that cycle, dust and debris build up along the duct walls and get redistributed through the house every time the air kicks back on.

- How often should air ducts be cleaned?
- There's no fixed schedule that fits every house. What matters more is what a contractor finds when they look. Dust coming out of the vents when the blower kicks on, a musty smell that wasn't there before, or someone in the house dealing with more allergy symptoms than usual are all reasons to have it looked at sooner. If your ducts were never cleaned since the house was built, that's worth mentioning when you call.
- Is air duct cleaning worth it?
- It depends on why you're asking. If your filter is clogged fast, if you can see dust building up around the vents, or if the ductwork was exposed during a renovation, cleaning solves a real problem. If you're just going by a general feeling that it's been a while, a contractor can inspect the ducts first and tell you whether cleaning will actually change anything. Ducts that look fine inside won't clean any better than they already are.
- What does air duct cleaning involve?
- A contractor connects a vacuum system to the ductwork and uses brushes or compressed air tools to knock loose dust and debris from the inside of the ducts, then pulls it out through the vacuum. They'll usually go through every supply and return vent in the house, along with the main trunk lines. The filter itself isn't part of duct cleaning. That's a separate part you or a contractor replace on its own schedule.
