Eight months of heating pushes dust through your ducts
Your furnace runs October through May here, close to eight months a year. Every time it kicks on, air moves through the ducts and carries dust, pet hair, and whatever settled on the floor of that ductwork back into your rooms. With winter nights averaging 25°F, the furnace cycles on and off many times a day for months straight, and each cycle pushes more through the system.
Canyon County has seen 37 winter storms and 13 damaging wind events over the past ten years. Wind like that drives dust and debris into homes around doors, windows, and vents, and it ends up in the ductwork along with everything else. A duct system loaded with that buildup blows dustier air into the house and makes the furnace work through a dirtier path to heat every room.

- How often should air ducts be cleaned?
- There is no fixed schedule that fits every house. If anyone in the house has allergies, you had pets shedding into the return vents, or you just finished a remodel that filled the house with drywall dust, it is time. Check the supply vents for dust buildup around the edges. That is a sign the ducts are due.
- Is air duct cleaning worth it?
- It is worth it when there is a real reason for it, not on a fixed schedule just to have it done. Dust blowing out of the vents, a musty smell when the furnace kicks on, or dust that resettles on furniture within a day or two of cleaning are all signs the ducts themselves are the problem. If none of that is happening, the furnace filter is probably doing its job and cleaning will not change much.
- What does air duct cleaning involve?
- A contractor connects a powerful vacuum to the duct system, then uses brushes or air tools to knock loose dust and debris from inside the metal so it gets pulled out rather than pushed further into the ducts. Every supply and return vent gets opened up and cleaned, and the furnace or air handler itself usually gets a pass too since that is where a lot of the buildup collects. The job covers the whole system, not just the vents you can see.
