Seven months of heating pushes air through the same ducts
Your furnace runs October through April here, seven months out of the year. Every one of those months, air moves through the same ducts, and whatever is sitting in them moves with it. Dust, pet hair, and anything that settled over the warm months gets stirred up and pushed into the rooms you're heating.
Randolph County has seen 202 damaging wind events and 7 winter storms over the past ten years. Storms like that knock out power, and a quarter of North Carolina households lost power for 24 hours or more in 2024 alone. When a system sits off during an outage, dust settles into the ductwork, then blows loose again the moment the furnace kicks back on.

- How often should air ducts be cleaned?
- There's no fixed schedule that fits every home. Clean them when you see a reason. Dust that keeps coming back after you wipe it down, a musty smell when the furnace or AC kicks on, or a renovation that left dust behind the vents all count. Ducts that look clean and cause no problems don't need attention just because time has passed.
- Is air duct cleaning worth it?
- It's worth it when there's a real reason behind it, not as routine maintenance on its own. Dust blowing out of the vents, a musty smell when the system runs, or a home that was recently renovated are all good reasons to have it done. If none of that applies, the dust sitting in your ducts probably isn't costing you anything.
- What does air duct cleaning involve?
- A contractor connects a vacuum system to your ductwork. Brushes or air tools knock dust and debris loose from inside the supply and return ducts as the vacuum pulls it out. They'll also clean the grilles and check the coil and blower while they're in there, since dust in the ducts often ends up on both. A contractor can walk through what your specific system needs before starting.
