Eight months of forced air packs your ducts with dust
Your furnace runs October through May here, close to eight months of the year. That is a long stretch of air moving through the same ductwork night after night, on winter nights that average 13°F. Every pass carries dust and pet hair through the system, and some of it settles in the ducts instead of blowing back out through the vents.
Wind is part of the picture too. Yankton County has logged 62 damaging wind events over the past ten years, and wind that strong works dust and debris into gaps in a duct system that most homeowners never see. Over eight months of heating, that buildup sits in the ducts and gets pushed into the air every time the furnace runs.

- How often should air ducts be cleaned?
- There's no fixed schedule that fits every home, so a contractor should look at your ducts before you pick a number of years. Dust buildup, a musty smell when the furnace runs, or visible debris around the vent covers are what actually signal it's time, not the calendar. Homes here run the furnace October through May, eight months a year, so ducts get more hours of airflow than they would in a place with a shorter heating season, which gives dust more chances to settle.
- Is air duct cleaning worth it?
- It's worth it when your ducts have a real buildup problem, not as routine maintenance on a schedule. Signs it's worth doing include dust blowing out of vents when the furnace kicks on, a musty smell, or debris you can see around the registers. A contractor can run a camera through the ductwork and tell you whether cleaning will make a real difference in your air or whether the money is better spent elsewhere.
- What does air duct cleaning involve?
- A contractor connects a vacuum system to your ductwork and uses brushes or air tools to loosen dust and debris from the inside of the duct walls, then pulls it out through the vacuum. Registers and return grilles get cleaned along with the ducts themselves. On a full job the furnace fan and coil may get cleaned too, since the same air that moves through the ducts moves through those parts.
