Eight months of heating pushes air through the same ducts
Your furnace runs from October through May here, eight months of the year. That is a long stretch of the same air moving through the same ducts, and whatever is sitting in them gets pushed into every room over and over during that time.
Winter nights average 19°F in Brigham City, so the furnace is cycling on and off often to keep the house warm. Every cycle pushes air through the ducts again. A duct system that starts the season with dust and debris in it keeps circulating that through the house for the full eight months.
- 8 months

- How often should air ducts be cleaned?
- There is no fixed schedule that fits every house. Homes here run the furnace eight months of the year, October through May, so dust has more months to move through the system than in a place with a shorter heating season. 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 is worth it when there is a real reason for it, like dust visibly blowing out of the vents, a musty smell, or signs that rodents or insects got into the ductwork. It will not fix a furnace that is running poorly and it will not lower your heating bill on its own. A contractor can check the ducts and tell you whether cleaning will actually help your situation.
- What does air duct cleaning involve?
- A contractor connects a vacuum system to the ductwork, then uses brushes or air tools to knock loose the dust and debris built up inside the supply and return ducts so it can be pulled out through the vacuum. The grilles and register covers get cleaned too, along with the coil and blower housing where dust tends to collect. The system is sealed back up afterward so air is not leaking into the walls or attic.
