Flex duct + plenum cleaning in Missouri City (77459) π before and after.
Scroll the first few photos: that's dust and grime built into the fiberboard plenum and packed down the inside of the flex duct runs. Now look at the after shots β clean collars, clean plenum, clean duct.
Here's what most homeowners never get told. Your supply plenum is the box where conditioned air collects before it's pushed out to every room, and the takeoff collars are the openings each duct branches off from. If those are dirty, every cycle of your system is dragging that air back through the house. A budget "vent cleaning" hits the registers you can see and stops there. Cleaning the plenum and the collars is what actually resets the system at the source.
This was a straight duct and plenum cleaning β no upsells, no invented problems, just the full system done right. Family-owned here in the Houston area since 2002, A+ with the BBB, 600+ reviews.
