Nine months of heat pushes a lot of air through your ducts
Your furnace runs September through May in Woodstock, nine months out of the year. That is nine months of air moving through the same ductwork, picking up dust and pulling it along every run in the house.
Winter nights here average 12°F, so the furnace is cycling on and off through the night to keep up. Every time it shuts off and starts again, it pushes another round of whatever has settled in the ducts back into the rooms you're heating.

- How often should air ducts be cleaned?
- There's no fixed schedule that fits every home, but a few years between cleanings is reasonable for most. If anyone in the house has allergies, or you've had work done that left dust in the attic or crawlspace, sooner makes sense. A furnace that runs September through May here is moving air through those ducts most of the year, so buildup happens steadily rather than in just one season.
- Is air duct cleaning worth it?
- It's worth it when there's a real reason for it, like dust visibly blowing out of the vents, a musty smell when the furnace kicks on, or recent work done in the attic or crawlspace. It won't lower your heating bill or fix a furnace that's struggling. What it does is clear out what's actually built up in there, so ask a contractor to look at your ducts before deciding rather than doing it on a schedule alone.
- What does air duct cleaning involve?
- A contractor connects a vacuum system to your ductwork and uses brushes or air tools to knock loose dust and debris, then pulls it out through the vacuum. Each supply and return vent gets cleaned, along with the main trunk lines. They should also check the furnace or air handler itself, since dust collects on the blower and coil too, not just in the ducts.
