Eight months of heat means eight months pulling air through the same ducts
Your furnace runs October through May here. Every one of those months, it is pulling household air through the ducts and pushing it back out, and whatever is riding in that air settles along the way. Eight months is a long stretch for dust to build up in a system.
St. Clair County sees real storms, 13 winter storms and 82 damaging wind events over the past ten years. Power drops with them, and across Michigan a third of households lost power for a full day or more in 2024. When the furnace stops and starts back up, it pushes against whatever has settled in the ducts since the last cleaning.
- 8 months
- October through May, your furnace pushes air through your ducts

- How often should air ducts be cleaned?
- Most homes do fine having it done every few years, not on a strict yearly schedule. Get it done sooner if anyone in the house has allergies, or you've had a rodent problem, water damage, or a renovation that kicked up dust and debris. Homes with pets or smokers tend to need it more often too, since hair, dander, and residue build up faster in the ductwork. If you can't remember the last time it was done, that's reason enough to have a contractor take a look.
- Is air duct cleaning worth it?
- It's worth it when there's a real reason behind it, like visible dust coming from the vents, a musty smell when the system runs, or someone in the house dealing with unexplained allergy or breathing issues. It won't lower your heating bills or fix a system that's running poorly for other reasons, so it's not a cure-all. But clearing years of dust and debris out of the ducts does mean cleaner air moving through the house, and that matters here with the furnace running eight months out of the year. A contractor can look at your ducts and tell you honestly whether cleaning makes sense right now.
- What does air duct cleaning involve?
- A technician connects a vacuum system to the ductwork to create negative pressure, then uses brushes or air whips to loosen dust and debris from inside the ducts so it gets pulled into the vacuum instead of blown into the house. Every supply and return vent gets cleaned, along with the main trunk lines. The furnace or air handler itself, including the blower and coil, usually gets attention too since that's where a lot of buildup collects. The filter isn't part of the ductwork, so make sure to replace it separately once the job's done.
