Air Duct Cleaning in Humble, TX

That's the most common call we get in Humble, and it usually traces back to the attic. On slab-on-grade homes with flex duct run through an unconditioned attic, the cold supply air hitting humid attic air makes the duct jacket and the boots sweat. Over years that moisture collects in low spots of sagging flex, settles dust into a damp film, and you smell it on startup before the line dries out. Cleaning the ducts and the plenum removes what's feeding the odor, but we'll also point out sagging runs, torn jacket, or a boot that isn't sealed at the ceiling, because if the sweating keeps up the smell comes back. The high water table and rainfall around here mean humidity isn't something you clean away once.

Usually yes, but it's a different job than the newer subdivisions. The 1950s–70s frame and brick ranches around the older part of Humble often still have original sheet metal trunks or ductboard. Sheet metal cleans up well and holds up to brushing. Ductboard is more delicate. The interior fiberglass face can be eroded by aggressive tooling, so we use softer agitation and more vacuum. If the ductboard is already flaking, water-stained, or the facing has broken down, we'll tell you straight that cleaning won't fix it and you're looking at replacement of that section. We'd rather say that than take money for work that won't hold.

It makes a real difference here. Loblolly pine is everywhere in this part of northeast Harris County, and the yellow pollen from roughly February through April gets into everything. You've also got needle and bark litter year-round and the jet and highway particulate drifting in from Bush Intercontinental. Most of the subdivisions built in the 80s through 2000s have a single hallway ceiling return, which means every bit of that goes through one filter. If that filter is a cheap one or it's been in longer than it should, the fines load up the blower wheel, the evaporator coil, and the supply runs. That's the mechanism, not pollen sitting in your ducts for years, but pollen that got past one return and settled downstream.

A few things move the number most around here. First, how many supply runs and returns you have: the single-return hallway layouts in the newer subdivisions are simpler than an older ranch that's been added onto with a second system. Second, duct type. Attic flex is straightforward, but original sheet metal or ductboard in the older town-core homes takes more time and more care. Third, attic access and condition. Humble attics get hot and tight, and if the flex is buried under blown insulation or the runs are long and sagging, the work takes longer. We look at all of that before we give you a number, not after.
