Eight months of furnace air moving through your ducts
Your furnace runs from October through May here. That is most of the year with air moving through the same ducts, and every month it runs, dust and fine debris settle along the duct walls. With winter nights averaging 13°F, the furnace is cycling on and off often to hold the temperature, pushing that air through again and again.
That buildup narrows the space air has to move through, so the furnace works harder to push the same amount of heat into your rooms.

- 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 doing sooner rather than later. Homes with pets or a recent water issue in the ductwork also tend to need it more often. A contractor can look at what's actually in your ducts and tell you if you're due.
- Is air duct cleaning worth it?
- It depends on what's in your ducts. If you can see dust building up around your vents, or a family member's allergies flare up more at home than elsewhere, cleaning will likely help. If your ducts are clean and your filter gets changed on schedule, there may not be much to gain. A contractor can inspect the ductwork and tell you honestly whether it's needed before any work starts.
- What does air duct cleaning involve?
- A technician connects a vacuum system to your ductwork and uses brushes or air tools to loosen dust and debris from inside the ducts, then pulls it out through the vacuum. They'll typically go through each supply and return vent, and check the vent hood and the coil area near the furnace, since dust collects there too. Once the ducts are clean, they close everything back up and check that airflow is moving through the system the way it should.
