Nine months of heat means nine months pushing dust through your ducts
Your furnace runs September through May here, nine months out of the year. Every time it kicks on, air moves through the ductwork and carries dust, pet hair, and whatever else settles in there along with it. On the nights that drop to 17°F, that furnace is cycling on and off for hours, and each cycle pushes more air through the same ducts.
With the power going out for a day or more in a good number of Colorado households last year, storms here also mean a furnace that stops and restarts more than it would somewhere calmer. Every restart stirs up what has settled in the ducts since the last one. Over a winter that runs this long, that buildup can block airflow to some rooms and make the furnace work harder to heat the house evenly.

- How often should air ducts be cleaned?
- There's no fixed schedule that fits every home, so a contractor should look at the ducts to tell you what they need. If anyone in the house has allergies, or you've had a furnace swap or a remodel that left dust behind, get them checked sooner rather than waiting. Homes with pets or a lot of dust tend to need it more often too. Going by what the ducts actually look like beats going by the calendar.
- Is air duct cleaning worth it?
- It depends on what's going on in your ducts. If you can see dust building up around the vents, or the house seems dustier than it should, cleaning them makes a real difference. If nobody in the house has allergies and the ducts look clean, you may not get much out of it. It won't lower your heating bills or fix a furnace that's running poorly, those are separate problems with separate causes.
- What does air duct cleaning involve?
- A contractor connects a vacuum system to the ductwork and uses brushes or air whips to loosen dust and debris, then pulls it out through the vacuum. Every supply and return in the house gets cleaned, not just a few. The furnace or air handler usually gets attention too, since dust collects on the blower as much as anywhere in the system. The filter should be changed afterward, since it does a different job than the ducts and won't clean itself.
