Eight months of heat pushes a lot of air through your ducts
Your furnace runs October through May here, eight months of the year. That is most of the calendar, and every one of those months your blower is pushing air through the same ductwork, pulling in dust and pet hair and whatever else settles in the return before sending it back out warm.
Cedar Rapids winters add wind on top of that. Linn County has seen 156 damaging wind events and 30 winter storms in the last ten years, and wind finds the gaps around older duct joints, drawing in attic dust or crawlspace air with it. On nights that average 15°F, your furnace is running long and often to keep up, so anything sitting in that ductwork is moving through the house right along with the heat.

- How often should air ducts be cleaned?
- There is no fixed schedule that fits every house. Pets, a recent renovation, or someone in the house with allergies are reasons to have it done sooner rather than wait for a set number of years. If you see dust building up around the vent covers or notice a musty smell when the furnace kicks on, that is a sign to have it looked at.
- Is air duct cleaning worth it?
- It is worth it when there is a real reason behind it, like dust that keeps coming back after you clean, a musty smell from the vents, or renovation work that likely sent debris into the duct system. It will not lower your heating bill or fix an allergy on its own. The value is in clearing out what has built up inside ducts you cannot reach yourself.
- What does air duct cleaning involve?
- A contractor connects a vacuum to the duct system to pull it under negative pressure, then uses brushes or air tools to knock dust and debris loose so it gets pulled into the vacuum instead of blown into the house. This covers the supply and return ducts, the grilles, and often the coil and blower compartment inside the furnace or air handler. The filter usually gets replaced too, since it is the last thing catching what moves through the system.
