Eight months of heating pushes air through your ducts
Your furnace runs October through May here, eight months of the year. On winter nights that average 14°F, it runs long and often to keep the house warm, and all that time moving air pulls dust and debris deeper into the trunk lines and vents.
Marshall County has seen 21 winter storms and 65 damaging wind events over the past ten years. Storms like that can knock out power and shut the furnace down mid-cycle, and when it starts back up it pushes whatever settled in the ducts while it sat idle back through the house.

- How often should air ducts be cleaned?
- Most homes do fine having it done every few years, not every year. If anyone in the house has allergies, or you have pets that shed, or you just finished a remodel, do it sooner since dust and debris build up faster in those cases. A contractor can look at what is actually in your ducts and tell you if it is time.
- Is air duct cleaning worth it?
- It depends on what is actually in your ducts. If you can see dust blowing out of the vents, or there is visible mold, or a pest problem, cleaning solves a real issue. If the ducts look fine and nobody in the house has breathing trouble, the payoff is smaller. A contractor can look inside the ducts with a camera and tell you whether there is enough buildup to matter before you decide.
- What does air duct cleaning involve?
- A contractor connects a vacuum system to the ductwork and uses brushes or air tools to knock loose dust and debris, then pulls it out through the vacuum. Each supply and return vent gets cleaned, and the main trunk lines get the same treatment. The furnace or air handler blower compartment usually gets cleaned too, since that is where air picks up whatever is sitting in the system before it moves through the ducts.
