Seven months of heating pulls a lot of air through your ducts
Your furnace runs October through April here, close to seven months a year. Every one of those months, it is pulling air through the same ducts, over and over, night after night when it is 25°F outside. That much moving air carries dust and settles some of it out along the way.
Rolla has also seen its share of wind, 56 damaging wind events and 10 winter storms over the last ten years. Storms like that push outside air into houses through gaps a normal day would not, and whatever comes in with it ends up moving through the same ductwork. Over enough months and enough storms, that buildup is what a duct cleaning is meant to clear out.

- How often should air ducts be cleaned?
- There is no set schedule that fits every house. A home with pets, a smoker, or recent renovation dust will need it sooner than one without. If anyone in the house has started noticing more dust or allergy symptoms indoors, that is worth acting on rather than waiting.
- Is air duct cleaning worth it?
- It depends on what is actually in your ducts. If you can see dust building up at the vents, or you know there has been construction, rodents, or water in the ductwork, cleaning solves a real problem. If your filter gets changed on schedule and nothing unusual has happened to the system, dirty ducts are less likely to be behind allergy complaints or dust in the house, and a contractor can look before you pay for a cleaning you may not need.
- What does air duct cleaning involve?
- A contractor connects a vacuum system to your ductwork and uses brushes or air tools to knock debris loose from the inside of the duct walls, then pulls it out through the vacuum before it can resettle. Supply and return vents get cleaned along with the ducts themselves, and the furnace or air handler's blower compartment usually gets attention too since it moves the air through everything else. The filter gets replaced or checked as part of the job, since a clogged filter puts dust right back into the system.
