Nine months of heat moves a lot of dust through those ducts
From September through May your furnace is pushing air through the same ductwork, with nights averaging 13°F in the dead of winter. That is a long season of dust and dander getting pulled through the system and settling in the runs where the air moves slowest.
Grand Isle County has seen 16 winter storms and 33 damaging wind events over the past ten years, and outages come with that kind of weather. When the power drops and the furnace stops, then kicks back on, it stirs up whatever has settled in the ducts and pushes it back into the rooms you live in.

- How often should air ducts be cleaned?
- There is no fixed schedule that fits every home. Houses with pets, a recent renovation, or someone with allergies tend to need it more often than others. If no one in the house has noticed dust at the vents or an odor when the furnace runs, there is no reason to move the timeline up. A contractor who looks at the actual ducts can tell you what makes sense for this house.
- Is air duct cleaning worth it?
- It depends on what is going on in the ducts. If dust is visibly blowing out of the vents, there is a musty smell when the system runs, or the ducts were exposed to construction dust or pests, cleaning is worth doing. If the ducts are newer and the filter gets changed on schedule, there may not be much to gain from it right now. A contractor can look at the ducts and tell you whether cleaning will make a real difference in this house.
- What does air duct cleaning involve?
- A contractor connects a vacuum system to the ductwork and uses brushes or air tools to knock loose dust and debris from inside the duct walls, then pulls it out through the vacuum. Registers and grilles get cleaned too, along with the return air ducts. On a forced air system, the blower compartment and coil are often checked at the same time since air moves through them on its way to the ducts.
