Eight months of heating pushes air through your ducts nonstop
Your furnace runs from October through May here, eight months of the year. Every time it kicks on, air moves through the ductwork, and whatever is sitting in those ducts moves with it. Dust, pet hair, and the fine debris that settles between cleanings gets stirred up and pushed into the rooms you're heating.
McLean County has seen 136 damaging wind events and 11 winter storms over the past ten years. Wind drives dust and debris into attics, crawl spaces, and anywhere ductwork runs through unconditioned space. That debris finds its way into the return air and settles inside the ducts, building up over a heating season that runs longer than most.

- How often should air ducts be cleaned?
- There's no fixed schedule that fits every house. If anyone in the house has allergies, or you just finished a remodel that kicked up dust and drywall debris, it's worth cleaning them sooner rather than later. Homes with pets or a smoker tend to need it more often too. Outside of those cases, a contractor can look at your ducts and tell you whether it's needed.
- Is air duct cleaning worth it?
- It depends on why you're considering it. If you can see dust blowing out of the vents, or a room fills with dust again days after you clean it, cleaning the ducts will fix that. It won't lower your heating bills or stop unrelated allergy symptoms, so if that's the goal, the money is better spent elsewhere.
- What does air duct cleaning involve?
- A contractor connects a vacuum to the duct system and uses brushes or air tools to knock loose dust and debris from inside the vents, then pulls it all out through the vacuum. Every supply and return vent in the house gets cleaned this way, and the vent covers themselves get wiped down. On a forced-air system, the coil and blower housing usually get checked at the same time, since dust builds up there too.
