Seven months of heating pushes air through ducts that rarely get a break
Your furnace runs October through April here, seven months of the year. That is seven months of air moving through the same ducts, carrying dust and whatever else settles in them back into the rooms you live in.
Loudon County has had 10 winter storms and 60 damaging wind events over the past ten years. Storms like that knock out power, and a fifth of Tennessee households lost power for a full day or more last year alone. When the furnace stops and starts back up after an outage, it pushes through ducts that had time to collect dust while the system sat idle. In a county where most homes are single-family and owner-occupied, that buildup is something you deal with once, not something that gets replaced with the next tenant.

- How often should air ducts be cleaned?
- There's no set schedule that fits every home, so most contractors go by condition rather than a fixed number of years. Homes with pets, a recent renovation, or someone with allergies may need it sooner. If you can see dust building up at the vents or the air feels dusty right after the furnace or AC kicks on, that is a sign to have someone look sooner rather than later.
- Is air duct cleaning worth it?
- It is worth it when there is a real reason behind it, like visible dust, a musty smell from the vents, or work that left debris in the ductwork. It will not lower your heating or cooling bills and it will not fix an allergy on its own. A contractor can look at your ducts and tell you whether cleaning will actually help your situation.
- What does air duct cleaning involve?
- A contractor connects a vacuum system to your ductwork and uses brushes or air tools to knock loose dust and debris from inside the supply and return ducts, then pulls it out through the vacuum. The vents, the furnace blower compartment, and sometimes the coil get cleaned as part of the job too. Once it's done, the ducts should be free of the dust and debris that had built up inside them.
