Nine months of heat running through the same ducts
Your furnace runs September through May here, nine months of the year. Winter nights averaging 5°F mean it doesn't cycle off for long. Warm air moving through the ducts that whole stretch carries dust into every room, and it settles in the runs between cycles.
McLean County sees hard weather too, 27 winter storms and 88 damaging wind events over the last ten years. Wind that strong finds the gaps around a house, and what it pushes in ends up pulled through the return and into the ductwork along with everything else.

- How often should air ducts be cleaned?
- Most homes only need duct cleaning every few years, and some go longer than that. Pets, a recent renovation, or someone in the house with allergies can call for it sooner. A contractor can look at your ducts and tell you whether now is the time or whether it can wait.
- Is air duct cleaning worth it?
- It's worth it when there's a real reason for it, like dust coming out of the vents, a musty smell when the furnace kicks on, or work that opened up the ductwork recently. It won't lower your heating bill or fix a furnace problem on its own. A contractor can look at your ducts and tell you whether cleaning will actually help your situation.
- 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, then pulls it out through the vacuum before it can resettle in the ducts. They'll also check the vents, the return, and the coil area near the furnace, since dirt collects there too. The furnace filter still needs regular changes after cleaning, since that's what keeps dust out of the air in the first place.
