Nine months of heating means nine months of dust moving through your ducts
Your furnace runs September through May here, close to nine months a year. Every time it kicks on, air pushes through the ductwork and out into your rooms, carrying along whatever has settled inside. On the nights that drop to 13°F, that furnace is cycling on and off for hours at a stretch, and each cycle moves more air through the same ducts.
Outagamie County has seen 22 winter storms and 79 damaging wind events over the past ten years. A power outage during one of those means the furnace stops moving air until it comes back on, and then it is pushing against nine months of buildup all over again.

- How often should air ducts be cleaned?
- Most homes do fine with a cleaning every few years, but there's no fixed schedule that fits every house. If anyone in the house has allergies, or you've had a rodent problem or a renovation that kicked up dust and drywall debris, it makes sense to do it sooner. Homes here run the furnace nine months a year, September through May, which pushes more air and more dust through the ducts than a house that only heats for a few months of the year. A contractor can look at what's actually built up in there and tell you if it's time.
- Is air duct cleaning worth it?
- It's worth it when there's a real reason for it, like visible dust coming out of the vents, a musty smell when the furnace or AC kicks on, or debris you can see when you pull a vent cover off. It won't fix an allergy problem on its own, and it won't lower your heating bill. What it does is remove the dust, pet hair, and buildup that collects in the ducts over years of use. If your ducts look clean and nobody in the house has breathing problems, there's usually no urgent need for it.
- What does air duct cleaning involve?
- A contractor connects vacuum equipment to the duct system and pulls the dust and debris out, often loosening what's stuck to the duct walls first with brushes or air whips. They'll access the system through the vents in each room and at the main trunk lines near the furnace. The filter gets checked or replaced as part of the job, since it's what actually catches particles from the air rather than the ducts themselves. A good contractor will also check the vent hood and any exhaust connections while they're in there.
