Ten months of heating pulls dust through your ducts
Your furnace runs from September through June here, ten months of the year. That is ten months of air moving through the same ductwork, night after night, in a place where winter lows average 13°F. Dust and debris settle into the ducts over that stretch and the moving air keeps stirring what is already there.
Gillette has seen 49 winter storms and 202 damaging wind events over the last ten years, and statewide, 8% of households lost power for at least a day in 2024. Each outage shuts the system down cold, and each restart pushes another rush of air through ducts that were already holding buildup from the months before.

- How often should air ducts be cleaned?
- There is no fixed schedule that fits every house. Homes with pets, smokers, or someone with allergies tend to need cleaning sooner than others. If you see dust collecting around the vents or notice a musty smell when the furnace kicks on, that is a sign to have someone look at the ducts.
- Is air duct cleaning worth it?
- It is worth it when the ducts are actually dirty or something is restricting airflow. A contractor can look inside and tell you whether there is real buildup or whether the ducts are fine as they are. With the furnace running from September through June here, clean ducts mean less resistance for it to push against most of the year.
- What does air duct cleaning involve?
- A contractor runs brushes and a high-powered vacuum through the ductwork to loosen and pull out dust and debris. This usually covers the supply and return ducts and the grilles, and sometimes the coil and blower housing if those are within reach. The point is to clear out what has built up so air moves through the system the way it was designed to.
