Seven months of forced air moving through your ducts
Your furnace runs October through April here, and every bit of that heat travels through your ductwork before it reaches a room. Seven months of near-constant airflow pulls dust, pet hair, and the fine debris that collects in a house down into the trunk lines and branches, where it settles on the inside walls of the duct instead of passing through the filter.
Vigo County has seen 49 damaging wind events and 5 winter storms over the past ten years, the kind of weather that can knock out power and shut a furnace down mid-cycle. When the system stops and starts back up, it stirs up whatever has settled in the ducts and pushes it back into the air. In a house with forced air running most of the year, that buildup has a lot of chances to work its way into the rooms you live in.

- How often should air ducts be cleaned?
- There's no fixed schedule that fits every home. If you can see dust building up around your vents, the air coming out smells musty, or someone in the house has been dealing with more allergy trouble than usual, that's when cleaning makes sense. Homes with pets or a recent renovation tend to need it sooner than others. Short of those signs, a contractor can look at your ducts and tell you whether it's time.
- Is air duct cleaning worth it?
- It's worth it when there's a real reason behind it, not just as a routine chore. If your ducts have visible mold, a rodent or pest problem, or dust so heavy it's blowing back into the rooms, cleaning solves an actual problem. If nobody in the house has allergy trouble and the vents look clean, you likely won't notice a difference in comfort or in how your furnace or air conditioner runs.
- What does air duct cleaning involve?
- A contractor uses brushes and a vacuum system to loosen and pull debris out of the supply and return ducts, then checks the vent covers and the area around your furnace or air handler. The registers get cleaned too, since dust collects right at the opening. A full job covers every duct run in the house, not just the ones you can reach by hand.
