Nine months of heating leaves a lot behind in your ducts
Your furnace runs September through May here, nine months of the year. That is nine months of air moving through the same ductwork, carrying dust through the same runs day after day. On nights that average 8°F, the furnace runs long and often to keep the house warm, and every one of those cycles pushes more air, and more of what's in it, through the ducts.
Brookings County has logged 34 winter storms and 77 damaging wind events over the past ten years. Weather like that keeps a furnace working hard for most of the year, and all that runtime is what fills a duct system over time.

- How often should air ducts be cleaned?
- There's no fixed schedule that fits every home, but a good rule is to have them checked if it's been a few years since the last look. Homes with pets, a recent renovation, or anyone with allergies tend to need it sooner, since dust and hair build up faster in those cases. Heat is running through your ducts nine months out of the year here, so it's worth having a contractor check them if you can't remember the last time anyone did.
- Is air duct cleaning worth it?
- It depends on what's actually in your ducts. If dust is visibly blowing out of the vents, there's a musty smell when the furnace kicks on, or you know there's debris from a renovation or a pest problem, cleaning them is worth it. If the ducts look fine and nobody in the house has allergy symptoms tied to the air, you're probably not gaining much. A contractor can look at the actual ductwork and tell you whether there's buildup worth removing.
- What does air duct cleaning involve?
- A contractor connects a vacuum system to your ductwork and uses brushes or air tools to knock loose dust and debris from the inside of the duct walls, then pulls it out through the vacuum. They'll also clean the supply and return vents, and check the coil and blower near the furnace or air handler since dust collects there too. The system gets sealed back up afterward so air isn't leaking out at the joints.
