Nine months of heating pushes dust through the house
Your furnace runs September through May in Washakie County. That's most of the year moving air through the same ducts, and every pass carries a little dust and fine debris onto the duct walls. On winter nights averaging 12°F, the furnace cycles on and off often just to hold the temperature, and each cycle pushes more air through.
Wind is part of the picture too. The county has seen 27 damaging wind events over the past ten years, and wind drives dust and debris into any gap around vents or returns. That buildup settles in the ducts and gets circulated through the house every time the furnace runs, which is most days from fall through spring.

- How often should air ducts be cleaned?
- There is no set schedule that fits every home. Homes with pets, smokers, or someone with allergies tend to need it more often than homes without. If you had construction work or water damage that reached the ductwork, get it cleaned before you turn the heat on for the season. A contractor can look at your ducts and tell you whether they need it now or can wait.
- Is air duct cleaning worth it?
- It depends on what is actually in your ducts. If you see dust blowing out of the vents, or you can see buildup when you pull a vent cover off, cleaning them will help your air and can help your furnace run the way it is supposed to. If your ducts look clean and nobody in the house has breathing trouble, you may not need it yet. A contractor can look and tell you honestly whether it will make a difference in your house.
- What does air duct cleaning involve?
- A contractor connects a vacuum to your duct system to pull air through it while agitating the inside of the ducts to loosen dust and debris. They go vent by vent, cleaning the supply and return runs along with the grilles and registers. If your furnace has a blower or coil that is dirty, that gets cleaned too, since it is part of the same air path.
