Ten months of heating pushes dust through your ducts
Your furnace runs September through June here, ten months of the year. That's ten months of air moving through the same ducts, pulling in dust and grit and pushing it back out through the vents.
Wind adds to it. Natrona County has logged 269 damaging wind events over the past ten years, and wind works dust into a house through every gap it can find. That dust settles in the trunk lines and the branches feeding each room. A duct coated in it forces your furnace to push harder to move the same air, and what comes out the vents carries more of that dust into the rooms you breathe in.

- How often should air ducts be cleaned?
- There's no fixed schedule that fits every home. Heat runs here from September through June, so the system moves air through the ducts most of the year, and that means more dust settles inside them than in a house that only runs a few months a year. A contractor can look inside the ducts and tell you whether they need cleaning now or can wait.
- Is air duct cleaning worth it?
- It's worth it if you're seeing dust blow out of the vents, catching a musty smell when the system kicks on, or you can actually see debris built up inside the ducts. Cleaning clears that material off the duct walls so it stops circulating through the house. It won't fix weak airflow or a system that's running poorly for other reasons. If the ducts look and smell fine, there's no need to clean them just to keep to a schedule.
- What does air duct cleaning involve?
- A contractor hooks a vacuum system up to the ductwork, then uses brushes or air tools to knock dust and debris loose from inside so the vacuum can pull it out. Every supply and return vent gets done, along with the main trunk lines. The furnace or air handler is often cleaned in the same visit, since dust builds up there too. Vent covers usually come off, get cleaned on their own, and go back on at the end.
