Ten months of heat means ten months of dust moving through your ducts
Your furnace runs September through June here, ten months a year. That is most of the year pushing air through the same ductwork, and whatever rides in that air settles along the way. On nights that average 14°F, the furnace cycles on and off for hours, and every cycle moves more of it through the ducts.
Big Horn County has seen 91 damaging wind events over the past ten years. Wind like that drives dust into a house through every gap it can find, and the return duct pulls it straight into the system. Once it settles in the ducts, it does not leave on its own. It sits there until the air moving through the house is carrying it again.

- How often should air ducts be cleaned?
- There's no fixed number of years that fits every house. Your furnace runs September through June here, ten months of the year, so the ducts move a lot more air than they would somewhere with a shorter heating stretch. Signs like dust at the registers, a musty smell on startup, or anyone in the house with allergies are better guides than a calendar. A contractor who looks inside the ducts can tell you whether yours need it now.
- Is air duct cleaning worth it?
- It's worth it when there's a real reason behind it, not as something you do on a schedule. Dust blowing out of the vents, a musty smell when the system kicks on, or debris you can see at the register are signs worth acting on. A contractor can look inside the ducts and tell you honestly whether cleaning will help or whether the problem is really the filter or the coil.
- What does air duct cleaning involve?
- A contractor connects a vacuum system to the ductwork and uses brushes or air tools to loosen dust and debris from inside the duct walls, then pulls it out through the vacuum. Every supply and return in the house gets covered, along with the grilles and registers themselves. Depending on the job, parts of the furnace or air handler that the air passes through may get cleaned too. A contractor looking at your system can tell you what it needs before the work starts.
