Step 1 of 3: Equipment
Nine months of heat moving through the same ducts
Your furnace runs September through May here, close to nine months of the year. That's nine months of air pushed through the same ductwork, carrying dust into the runs and settling it along the seams and corners.
Winter nights averaging 16°F mean the system is running hard and often, not just long. Every one of those runs pulls household dust through the ducts and leaves more of it behind, and by the time the season breaks in May there's a lot sitting in the runs.

- How often should air ducts be cleaned?
- There's no fixed schedule that fits every home. If anyone in the house has allergies, or you've had a duct replacement or remodel that left dust behind, it's worth cleaning sooner rather than waiting. Homes with pets or a recent water issue in the ductwork tend to need it more often too. A contractor can look at your system and tell you what it needs.
- Is air duct cleaning worth it?
- It's worth it if your ducts are visibly dirty, dust settles fast after you clean the house, or you can see mold or debris at the vents. It won't lower your heating bills or fix a furnace that's struggling, so don't expect that from it. What it does is clear out what's built up so the air moving through your vents isn't carrying it into the rooms.
- What does air duct cleaning involve?
- A contractor runs equipment through the ductwork to loosen and pull out dust and debris, usually working from a vacuum connected to the system while agitation tools knock material loose inside the ducts. The supply and return vents get cleaned too, along with the grilles covering them. On a full job, the contractor will also check spots like the blower motor housing and coils where dust tends to collect.
