Eight months of heat means eight months of dust moving through your ducts
Your furnace runs October through May here, and on winter nights that average 12°F it doesn't shut off for long. Every time it kicks on, air moves through the ductwork and stirs up whatever has settled in there since the last cycle.
With 77 damaging wind events on record over the past ten years, homes in this county see a lot of gusty, blowing conditions that push dust and debris toward doors and windows. That works its way into the return air and settles in the ducts over a long heating season. The buildup doesn't stop your furnace from running, but it is what you're breathing every time the system kicks on.

- How often should air ducts be cleaned?
- There is no fixed schedule that fits every house. Homes with pets, a recent renovation, or someone with allergies tend to need it more often than others. If you can see dust building up at the vent covers, or the system seems to be pushing out more dust than it used to, that is a sign to have it looked at rather than wait.
- Is air duct cleaning worth it?
- It depends on what is actually in the ducts. If there is visible dust, debris, or signs of pests or mold, cleaning them makes sense and can cut down on what gets circulated through the house. If the ducts are newer or already reasonably clean, cleaning them on a fixed schedule regardless of condition does not add much. A contractor can look at the ductwork and tell you whether there is enough buildup to justify it.
- What does air duct cleaning involve?
- A contractor uses tools to loosen the dust and debris built up inside the ducts, then pulls it out with a high powered vacuum before it can resettle. This usually covers the supply and return ducts, the grilles and registers, and sometimes the coils and housing near the furnace or air handler. The point is to remove what has built up inside, not to change how the ductwork is laid out.
