Seven months of heating means seven months moving air through those ducts

Your furnace runs October through April here, seven months out of the year. On the cold nights, the ones that average 22°F through the winter, it runs longer and more often to keep the house warm. Every hour it runs, air moves through the ductwork, and whatever is sitting in those ducts moves with it, out through the vents and into the rooms you're breathing in.

Platte County has also seen 68 damaging wind events and 10 winter storms over the past ten years. Storms like that put strain on a house, and a furnace working through seven months of heating with ducts that haven't been cleaned is pushing that same buildup through the house on every run.

How often should air ducts be cleaned?
There is no fixed schedule that fits every home. Homes with pets, a recent renovation, or someone with allergies often need it more often than others. If you see dust building up around the vents or notice more dust in the house than usual, that is a better signal than any calendar date.
Is air duct cleaning worth it?
It depends on what is going on in your ducts right now. If there is visible dust, debris, or signs of pests, cleaning them out can help the air moving through your home. If your ducts look clean and your filter is doing its job, you may not need it yet. A contractor can look at your system and tell you whether it will make a real difference in your case.
What does air duct cleaning involve?
A contractor uses brushes and a vacuum system to loosen and pull dust and debris out of your ductwork. They work through each supply and return vent, cleaning the full run of duct rather than just what is visible at the opening. Some will also check the coil or blower housing while they are in there, since debris tends to collect in those spots too.
