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. Most of that on nights averaging 31°F, so the blower is moving air through the ducts for hours at a stretch, day after day. Dust, pet hair, and whatever settles in the ductwork gets pushed through the house every time the system runs.
Wilson County has had 260 damaging wind events and 11 winter storms over the last ten years. When wind drives dust and debris into a house, or a storm knocks out power and the system sits idle then kicks back on, more of that gets pulled into the ducts and stays there. In a county where most homes are owner-occupied, that buildup is something you live with rather than something a landlord deals with for you.

- How often should air ducts be cleaned?
- There's no fixed schedule that fits every house. Pets, a recent renovation, or someone with allergies are reasons to have it done sooner, since more dust and dander end up pulled into the return air. If no one in the house has noticed dust at the vents or breathing issues, there's no reason to move it up.
- Is air duct cleaning worth it?
- It's worth it when there's a real reason behind it, like visible dust blowing out of the vents, a musty smell when the furnace or AC kicks on, or debris left behind from recent work on the house. It won't lower your heating bill or fix an efficiency problem on its own. If nobody in the house is having breathing trouble and the vents look clean, cleaning the ducts on a whim doesn't buy you much.
- What does air duct cleaning involve?
- A contractor connects a vacuum system to the ductwork and uses brushes or air whips to knock loose dust and debris from inside the supply and return runs, then pulls it out through the vacuum. The vents, the coil area, and the blower compartment usually get cleaned in the same visit since they collect the same buildup. A contractor can walk through what your specific system needs before starting.
