Eight months of heating pushes air through your ducts
Your furnace runs October through May here, eight months out of the year. On nights that average 23°F, it cycles on and off for hours at a stretch, and every cycle pushes air through the same ductwork. Dust and the fine debris that settles in a house get pulled through and pressed into the seams and turns of the trunk lines over a season this long.
Miami County has also logged 69 damaging wind events over the past ten years, more than one every two months. Wind that strong can drive debris into vents and shift pressure through the return side of the system. None of that clears out on its own. It sits in the ducts and gets circulated every time the furnace runs.

- How often should air ducts be cleaned?
- There is no fixed schedule that fits every home. Most homes go years between cleanings, and it makes sense sooner if anyone in the house has allergies, if you just had a furnace swap or a remodel that left dust behind, or if you have pets shedding into the return vents. A water issue in the ductwork is another reason to move the timeline up rather than wait.
- Is air duct cleaning worth it?
- It depends on what is actually going on in your ducts. If you can see dust building up around the vents and nobody has looked at the ductwork in years, cleaning it makes sense, especially with the furnace running from October through May here. It will not fix an allergy problem by itself and it will not lower your heating bill, so go in expecting cleaner air moving through the house, not a cure for other problems.
- What does air duct cleaning involve?
- A contractor connects a vacuum system to your ductwork, then uses brushes or air tools to knock loose the dust built up on the inside walls of the ducts before pulling it out through the vacuum. They usually check the supply and return vents too, along with the coil and blower housing, since debris settles there as well. The filter typically gets replaced or cleaned at the same time, since a dirty filter puts dust right back into ducts that were just cleaned.
