Nine months of heat pushes a lot of air through your ducts
Your furnace runs September through May here, nine months of the year. Every one of those months it is pulling air through the same ductwork, over and over, night after night when it is 10 below outside. Dust and pet hair settle in the bends and the long runs, and nine months gives it plenty of time to build up.
Rice County sees its share of storms too, 34 winter storms and 36 damaging wind events over the last ten years. Wind that strong can force outside air and debris into a duct system through gaps most homeowners never see. That buildup sits in the ducts and blows back into the house every time the furnace kicks on.

- How often should air ducts be cleaned?
- There's no fixed schedule that fits every house, but a contractor can tell you what your ducts need by looking inside them. If anyone in the house has allergies, or you've had a remodel or a new furnace put in that left dust behind, it's worth checking sooner rather than later. Homes with pets often need it more often too, since fur and dander build up in the ductwork faster than dust alone.
- Is air duct cleaning worth it?
- It depends on what's going on in your ducts right now. If you can see dust kicking out of the vents when the furnace runs, or there's a musty smell when the air kicks on, cleaning them will make a real difference. If nothing looks or smells off and no one in the house has breathing trouble, you may not need it yet. A contractor can look inside the ducts with a camera and tell you what's actually in there before you spend money on it.
- What does air duct cleaning involve?
- A contractor hooks up a vacuum system to your ductwork and uses brushes or air tools to knock loose dust and buildup from inside the ducts, then pulls it all out through the vacuum. They'll typically go through the supply and return ducts, the vents themselves, and often the furnace or coil area since that's where a lot of buildup collects. Most jobs also include a check of the filter, since a clogged one will just undo the cleaning within a few months.
