Eight months of heating runs a lot of air through your ducts
Your furnace runs October through May here, eight months out of twelve. That is eight months of air moving through the same ducts, carrying dust, pet hair, and whatever else is in the house, and leaving some of it behind on the walls of the duct with every pass.
Winter nights averaging 13°F mean the furnace is cycling hard and often to keep up. More running time means more air moved and more buildup left behind. A duct system carrying that much dust pushes it right back into the rooms you're heating, and a blower working against a dirty duct system works harder to move the same air.

- How often should air ducts be cleaned?
- There's no fixed schedule that fits every home, and a contractor can tell you what your ducts actually need by looking at them. If anyone in the house has allergies, or you've had a pest problem or water damage in the ductwork, that's a reason to have them checked sooner rather than later. Homes here run the furnace October through May, so ducts are moving air most of the year and can collect more dust and debris in that time.
- Is air duct cleaning worth it?
- It depends on why you're considering it. If you're seeing dust come out of the vents, or you can see buildup when you look inside a duct, cleaning solves that. It won't lower your heating bills or fix an allergy on its own, since most of the dust in a house comes from the room itself, not the ductwork. Where it does matter is after construction work, a pest issue, or if the ducts were never cleaned since the house was built.
- What does air duct cleaning involve?
- A contractor uses a vacuum system to pull air through the ductwork while brushes or air whips loosen dust and debris stuck to the inside walls. Every supply and return duct in the system gets done, along with the grilles and registers. The furnace or air handler itself, including the blower and coil, gets cleaned as part of the job since it's connected to the same airflow. Access panels get cut into the ductwork where needed and sealed back up afterward.
