Eight months of heat pushes a lot of air through your ducts
Your furnace runs October through May here. That is most of the year moving air through the same ducts, and whatever is sitting in them gets pushed into every room over and over.
Walla Walla County has seen 67 winter storms and 37 damaging wind events over the past ten years. Storms like that knock out power, and when the furnace shuts off and starts back up, it stirs up whatever has settled in the ducts since the last cycle. With nights averaging 29°F in December through February, that system runs often enough that dust does not get much chance to just sit still.

- How often should air ducts be cleaned?
- There is no fixed schedule that fits every home, but most people have it done every few years unless something changes that sooner. Pets, a recent renovation, or someone in the house with allergies are reasons to move the timeline up. If you can see dust building up around your vents or notice a musty smell when the furnace kicks on, that is a sign to get it done rather than wait.
- Is air duct cleaning worth it?
- It is worth it when there is a real reason behind it, like visible dust, a musty smell, or work that opened up the ducts during a renovation. It will not lower your heating bill or fix an allergy on its own. What it does is remove buildup that has settled in the ducts over time, which matters in a house that runs its furnace from October through May like homes here do.
- 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 and debris from inside the ducts, then pulls it out through the vacuum. They will also check the supply and return vents, and often the coil and blower compartment near the furnace, since debris collects there too. The filter is a separate part and cleaning the ducts does not replace it.
