Ten months of heating pushes a lot of air through your ducts
Your furnace runs September through June here, which means the blower is moving air through your ductwork most of the year. Every pass carries dust, pet hair, and whatever else is in the house, and some of it settles in the ducts instead of coming back out through the vents.
Spokane County sees its share of winter storms, and outages come with them. When the power drops and comes back, the furnace starts back up and pushes out whatever settled in the ducts while it was off. Over years of that cycle, the buildup can work its way into the air moving through the house.

- How often should air ducts be cleaned?
- There's no fixed schedule that fits every home. Have them checked sooner if anyone in the house has allergies, if you just finished a remodel that put drywall dust into the vents, or if there are pets or a smoker in the house. A contractor can look inside the ducts and tell you whether they actually need cleaning.
- Is air duct cleaning worth it?
- It depends on why you're doing it. If dust is building up fast on furniture or someone in the house has breathing trouble, cleaning the ducts can help, since the same air keeps circulating through them all day. If you're hoping it will lower heating bills, there's less to it, ducts carry air and don't affect how much fuel the furnace burns. A contractor can look at your ducts and tell you what's actually in there before you decide.
- What does air duct cleaning involve?
- A contractor connects a vacuum to the duct system and uses brushes or air tools to knock loose dust, debris and pet hair from inside the ducts, then pulls it out with the vacuum. Every vent gets covered, including the return, and the furnace or air handler itself usually gets cleaned too since it's part of the same airflow path. Afterward there's no dust or debris left to blow back into the rooms.
