Air Duct Cleaning in Independence, MO

We clean both, but they get handled differently. The oversized plenum and the large round trunks off it hold a lot of settled debris, often decades of it, so those get worked with a rotary brush and heavy vacuum. The original wall stacks are the harder part: they're often plaster-lined or built into the framing, with no clean access and sometimes a nail or old patch inside. We reach those through the register openings and from the trunk side rather than forcing a tool down a stack that may not be sheet metal the whole way. If a stack is deteriorated enough that cleaning would make it worse, we'll tell you that instead of running equipment through it.

Cleaning helps, but in Independence the smell usually starts outside the ducts. Older basements here stay damp through humid summers, and when the return path runs through joist bays or panned-off floor cavities (common in the postwar ranches east and south of town), that damp basement air is part of what your system breathes. Cleaning removes the dust and organic material the moisture feeds on, which knocks the odor down. But if the basement itself stays wet, the smell comes back. We'll tell you what we find at the return, including whether the panned bays are open to the basement, so you know whether you're dealing with a duct problem or a moisture problem.

Mostly the system, not the square footage. A 1980s or 1990s build on the edge of town with a straightforward supply trunk and a reasonable number of registers is on the simpler end. A converted gravity system with an oversized plenum, several large round trunks and original wall stacks takes longer because of access alone. Some of those registers haven't come off in decades. Postwar ranches land in between, though panned return bays add time. Other things that move the number: the number of returns, whether there's a second system, and whether anything we open up turns out to be holding water damage rather than dust. We walk the house and tell you where it falls before we set up.

Same-day happens, mostly when a morning job finishes early or someone cancels, and it's more likely midweek than Friday. Normal scheduling is usually within a few days. Spring and early fall are our busiest stretches in eastern Jackson County. The tree pollen here runs heavy and people call when the system starts cycling after a long off season, so plan on a bit more lead time then. If you're calling because of a smell or something you can see at the register, say so when you call; that moves you up.

A few things repeat. In the converted gravity systems, disconnected or partly fallen joints inside the old plenum, where someone tied in modern trunk and the transition has worked loose. In the 1950s and 60s basement sheet metal, rust at the bottom seams and tape that's long since given up. In the panned return bays, open gaps pulling basement air. And scale and mineral buildup on anything near the humidifier or coil, because the water here is hard enough that it shows. We photograph what we find and show you, rather than describing it after the fact.
