Seven months of heating pushes air through the same ducts
Your furnace runs October through April here, seven months of the year. Winter nights average 30°F from December through February, so the burner is cycling on and off most nights that whole stretch, pushing air through the same ductwork night after night. Dust and everything else riding that air settles along the duct walls and on the coil.
Maury County has seen 104 damaging wind events and 9 winter storms over the past ten years. A storm like that can force outside air, dust, and debris into a duct system that already has months of buildup sitting in it, and that buildup keeps choking off airflow until rooms farther from the furnace stop getting their share of the heat.

- How often should air ducts be cleaned?
- Most homes don't need it on a fixed schedule at all. It matters more if anyone in the house has allergies, if you have pets shedding into the return vents, or if you just finished a renovation that kicked up drywall dust. Homes here run the furnace October through April, so anything sitting in the ducts over summer gets blown through the house as soon as the heat kicks on for the season. A contractor can look inside with a camera and tell you whether there's enough buildup to justify cleaning.
- Is air duct cleaning worth it?
- It's worth it if your ducts are visibly dirty, if dust is blowing out of the vents, or if rodents or construction debris have gotten into the system. A contractor can check inside the ducts and tell you whether there's real buildup or not. It won't fix a musty smell caused by a leak somewhere else, and it won't lower your energy bills on its own, so it helps to know what problem you're trying to solve before you book it.
- What does air duct cleaning involve?
- A contractor connects a vacuum to the duct system, then uses brushes or air whips to knock dust and debris loose from inside the ducts so it can be pulled out. They also clean the supply and return vents, and usually check the furnace or air handler while everything is open. The job covers the ductwork itself, not the filter, though most contractors will point out if yours needs replacing.
