Eight months of heating pushes air through your ducts nonstop
Your furnace runs October through May here, eight months out of the year. On nights that average 13°F in December through February, it cycles on and off for hours at a stretch, pulling household dust and whatever settled in the ducts back through the house every time it runs.
Wind and power are part of the picture too. Plymouth County has seen 51 damaging wind events and 26 winter storms over the past decade, and 15% of Iowa households lost power for a day or more in 2024. A furnace that stops and restarts, or a duct system that sits idle during an outage, gives dust more chances to settle before the next cycle stirs it up again.

- How often should air ducts be cleaned?
- There's no fixed schedule that fits every home, so let a real reason drive the timing. Visible dust blowing out of the vents, a musty smell when the furnace kicks on, or signs of pests in the ductwork all mean it's time. Homes here run the furnace October through May, eight months a year, so ducts get more use than in places with a shorter heating season and collect more of what moves through the air.
- Is air duct cleaning worth it?
- It's worth it if there's a real reason for it, like visible dust blowing out of the vents, a musty smell when the system runs, or signs of rodents or insects in the ductwork. It won't lower your heating bills or fix a furnace that's struggling, and there's no proof it prevents illness. For most homes without a specific problem, it's a maintenance choice rather than a necessity.
- 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 from inside the vents, then pulls it out through the vacuum. They'll go through every supply and return vent in the house, along with the main trunk lines, and check the coil and blower housing since those collect buildup too. A thorough job also seals off registers during the work so nothing gets pushed back into the room instead of out.
