Seven months of heating means seven months of dust moving through your ducts
Your furnace runs October through April here, close to seven months a year. Every time it kicks on, air pulls through the ductwork and carries whatever has settled in there back into the rooms you're heating. On the cold nights, down near 22°F, it's cycling on and off for hours at a stretch, so that same air is moving through the ducts again and again.
Clay County has also logged 9 winter storms and 116 damaging wind events over the past ten years. Storms like that can knock out power and shut the furnace down, and when it starts back up, it pulls in another round of whatever is sitting in the ducts.

- How often should air ducts be cleaned?
- There's no fixed schedule that fits every home. Homes with pets, a recent renovation, or someone with allergies tend to need it more often than homes without those things. If you can see dust building up around your vents or blowing out when the system starts, that's a sign to have them looked at rather than waiting.
- Is air duct cleaning worth it?
- It's worth it when there's a real reason for it, like visible dust, a musty smell when the system runs, or work done on the ductwork itself. It won't fix an allergy problem on its own and it won't lower your heating bills. A contractor can look at your ducts and tell you honestly whether cleaning will help your situation or whether the dust is coming from somewhere else, like a dirty filter.
- 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, then pulls it out through the vacuum before it can resettle. Every supply and return vent gets cleaned, along with the main trunk lines. The furnace or air handler and the coil often get attention too, since dust collects there and gets pushed through the ducts every time the system runs.
