Eight months of heating runs the dust through your ducts
Your furnace runs October through May here, eight months out of the year. Every time it kicks on, air moves through the ducts and pulls along whatever dust and debris has settled in them. On nights averaging 16°F, that furnace is cycling on and off for hours at a stretch, and each cycle pushes more air through the same ductwork.
Wind is part of the picture too. Arapahoe County has seen 97 damaging wind events over the past ten years, and wind drives dust and debris into any gaps around vents and duct seams. That buildup sits in the ducts and gets circulated through the house every time the system runs, which is most of the year here.

- How often should air ducts be cleaned?
- There's no fixed schedule that fits every home, so a contractor is the one who can tell you what yours needs. If anyone in the house has allergies, or you've had a rodent problem or a water leak near the ductwork, it's worth having them looked at sooner rather than later. Homes with pets or a recent renovation tend to collect dust and debris faster, which is a reason to move sooner, not a reason to wait for a set number of years.
- Is air duct cleaning worth it?
- It's worth it when there's a real reason behind it, like visible dust coming from the vents, a musty smell when the furnace runs, or debris you can see when you pull a vent cover off. It won't lower your heating bill or fix an allergy on its own. A contractor can look at your ducts and tell you whether cleaning will actually address what you're noticing.
- What does air duct cleaning involve?
- A technician connects a vacuum system to the ductwork and uses brushes or air tools to knock dust and debris loose from the inside of the supply and return ducts, then pulls it all out through the vacuum. The vent covers come off first, and the furnace or air handler often gets cleaned at the same time since it connects to the same air path. A thorough job covers every vent and return in the house, not just the ones you can reach easily.
