Seven months of forced air through the same ducts
Your furnace runs October through April here, seven months a year. Every hour it runs, it pushes air through the same trunk lines and returns, and whatever has settled in them gets stirred up and carried through the house again.
Rutherford County has had 137 damaging wind events and 9 winter storms over the past ten years. Wind that strong can force dust and debris into ductwork that runs through the attic or crawlspace, working it in through loose joints and gaps in the seams. That's more for the system to move through the house each time it cycles on.

- How often should air ducts be cleaned?
- There is 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 you see dust building up around the vents or notice a stale smell when the air kicks on, that is a sign to get it looked at rather than wait.
- Is air duct cleaning worth it?
- It is worth it when there is a real reason behind it, like dust that keeps coming back, a musty smell from the vents, or work that was just done on the ductwork itself. It will not lower your heating bills or fix an allergy on its own. A contractor can look at the ducts and tell you whether cleaning will help, or whether the real problem is the filter or a leak somewhere in the duct.
- What does air duct cleaning involve?
- A contractor connects a vacuum system to the ductwork, then uses brushes or air tools to loosen dust and debris along the way so it pulls out through the vacuum instead of blowing further into the house. The vents, the return grilles, and usually the coil get cleaned too, since dust settles there as much as inside the ducts. On a full house, that means working through room by room so nothing gets skipped.
