Air Duct Cleaning in Liberty, MO

Usually yes, though what we find varies a lot in those homes. A lot of the 19th and early 20th century houses around downtown Liberty have been through at least one or two heating system changes, so you'll see original metal trunk lines with newer branches spliced in, sometimes old gravity-furnace runs that were converted rather than replaced. Those big old trunks hold decades of debris along the bottom. The joints are often taped or sealed inconsistently, which matters because a basement that pulls in damp air will move that air through the system. We look at the condition of the metal first — if seams are rusted through or a section was abandoned in place, cleaning it isn't the answer and we'll say so.

This is the most common call we get in Liberty, and the ducts are often not the source. Limestone and clay soils here hold water against foundations, so basements stay damp and many homes run a sump pit. That humidity gets pulled into the return side, hits the cold evaporator coil, and you get biological growth on the coil and in the drain pan. The ducts then distribute the smell, which is why it seems like a duct problem. Cleaning supply runs without addressing the coil, the pan, and the return-side moisture gets you a few weeks of improvement at best. We inspect the coil as part of the job and tell you what's actually generating the odor.
