Seven months of heating pushes dust through the same ducts
Your furnace runs October through April here, seven months out of the year. The same air keeps moving through the same ducts that whole time, and whatever is loose in them settles a little more with each pass.
Sierra County has seen 32 damaging wind events over the past ten years. Wind like that drives dust into a house through every gap it can find, and that dust ends up pulled into the return and settled along the duct runs. With winter nights averaging 27°F, the furnace is doing most of the work moving air through this house, so what collects in the ducts is what the house breathes for seven months straight.
- 7 months
- October through April, your furnace pushes air through your ducts

- How often should air ducts be cleaned?
- There is no fixed schedule that fits every home, so go by what you notice. If anyone in the house has allergies, or you have had rodents or a water leak near the ductwork, get it done. Pets and recent renovation work also put more debris into the system, so those homes tend to need it sooner than others.
- Is air duct cleaning worth it?
- It is worth it when there is a real reason behind it, like dust coming out of the vents, a musty smell when the air kicks on, or work that was just done on the ducts themselves. It will not lower your heating bills or fix a furnace that is not working right. Think of it as keeping the air moving through your house clean, not as a repair.
- 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 the inside of the ducts, then pulls it all out through the vacuum. The supply and return vents get cleaned along with the ducts themselves. On most jobs the coil and blower get a look too, since dust that builds up there affects how well the air moves through the whole system.
