Eight months of heat means eight months pulling air through your ducts
Your furnace runs October through May here, close to eight months a year. Every one of those months it's pulling air through the same ductwork, and whatever is riding in that air, dust, pet hair, the fine grit that comes in on shoes, settles out along the way. It's a long stretch of the year for buildup to collect and not much of a stretch when it doesn't.
The buildup doesn't move on its own. It sits in the runs until the day the furnace pushes hard enough to carry some of it back into the rooms you're heating.

- How often should air ducts be cleaned?
- Most homes do fine having ducts checked every few years, though there is no fixed schedule that fits every house. If anyone in the house has allergies, if you have pets shedding into the return vents, or if you just finished a renovation that kicked up drywall dust, check them sooner. Look inside a supply vent with a flashlight. If you see dust matted along the sides rather than just a light coating, it is time.
- Is air duct cleaning worth it?
- It depends on what is actually in your ducts. If you can see dust buildup, if the house smells musty when the furnace kicks on, or if someone in the home has breathing trouble that gets worse indoors, cleaning is worth doing. If none of that applies, cleaning ducts that are already fairly clean will not make a noticeable difference in air quality. A contractor can look at your system and tell you which case you are in.
- What does air duct cleaning involve?
- A contractor connects a vacuum system to your ductwork and uses brushes or air tools to knock dust and debris loose so it can be pulled out, working through each supply and return line. The furnace or air handler itself gets cleaned too, since dust collects around the blower and coil. Grilles and vent covers usually come off for a proper wipe-down before they go back on. A full job covers every line in the house, not just the ones near the furnace.
