Eight months of heating runs a lot of air through your ducts
Your furnace runs October through May here, eight months of the year. Winter nights average 21°F from December through February, so the blower is moving air through those ducts most hours of the day and night for most of the year. Every pass carries dust and whatever else is in the house, and some of it settles inside the duct instead of blowing back out through the vents.
Monroe County has seen 95 damaging wind events and 8 winter storms over the past ten years. When a storm knocks out power, the furnace stops and the house sits without airflow until it comes back. Across Michigan, a third of households lost power for at least 24 hours in 2024. Dust settles in the ducts during those stretches, and it is still there when the blower starts moving air again.

- How often should air ducts be cleaned?
- There's no fixed number of years that fits every home. Homes with pets, a recent renovation, or someone with allergies usually need it more often than one without those things. If you notice dust building up fast after a cleaning, or musty air when the furnace kicks on, that's a sign to have it looked at sooner rather than waiting.
- Is air duct cleaning worth it?
- It's worth it when there's a real reason behind it, like heavy dust, a smell you can't place, or work done on the ductwork itself. It won't lower your heating bill or fix a furnace that's struggling, so don't expect that from it. What it does is clear out what's built up inside the ducts so the air moving through your home isn't carrying it.
- 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 inside, then pulls it out through the vacuum so it doesn't spread into the house. The supply and return vents get cleaned along with the main trunk lines. Register covers usually come off during the process and get wiped down or cleaned separately.
