Eight months of heat moving through the same ducts
Your furnace runs from October through May here, eight months of the year. Winter nights average 18°F from December through February, so on the coldest nights the burner is cycling on and off for hours at a time, and the blower pushes air through the same trunk lines and branches every time it fires. Dust and whatever else is in the house rides along with that air, and some of it settles on the inside walls of the ducts with each pass.
Colorado saw 13% of households go at least 24 hours without power in 2024, and the county has logged 202 winter storms over the past ten years. When the power drops and the furnace shuts off, then comes back on, the first blast of air can knock loose what has settled in the ducts and send it into the house.

- How often should air ducts be cleaned?
- There is no fixed schedule that fits every home. Look at the registers themselves. If dust is visible around them, or the air coming out carries a smell or a haze, that is the sign to get them cleaned. A pet in the house, a recent renovation, or someone with allergies are all reasons to check sooner rather than later.
- Is air duct cleaning worth it?
- It depends on what is actually in your ducts. If there is visible dust, mold, or construction debris, clearing it out can ease breathing problems that buildup was causing. If the ducts look and smell fine and no one has new allergy symptoms, there may be nothing to gain from cleaning them right now.
- What does air duct cleaning involve?
- A contractor uses brushes and a high-powered vacuum to loosen and pull dust and debris out of the ductwork. The registers and grilles get cleaned along with the vents themselves. Access points are opened as the work moves through the system, so the ducts you cannot see get cleaned, not just the parts near the vents.
