United Air Duct Cleaning And Restoration Services

Before and after from a dryer vent in west Houston this week. That gray wall in the first photo? All lint. It's the number one cause of dryer fires, and the homeowner's only clue was towels needing two cycles. One hour later: bare metal, full airflow. When did yours last get cleaned?

See that rust line? That's what condensation does when nobody's looked inside the AC closet for a few years. Found it on a Katy job, sealed it up after a full duct cleaning. Worth having someone open yours up once in a while.

That little blue glow is the last step of a duct cleaning done right. UV lamp aimed at the coil, keeping mold from moving back in after we've cleared everything out. Kelliwood job, start to finish in an afternoon.

Opened up a return plenum in Kelliwood Greens this week and the duct board hadn't seen daylight in years. Cleaned it wall to wall, resealed the collars, and set a UV lamp at the coil before we buttoned it up. The after photos say the rest.

That blue glow is doing real work. This PURE-M UV light went in right after a full duct cleaning at a Houston-area home, aimed straight at the evaporator coil so mold never gets a foothold on the wet surface. Cleaned once, protected after. Full photo walkthrough on the blog if you want to see what came out of those ducts first.

Katy humidity doesn't just make summer miserable — it works on the inside of your ductwork too.

Fiberglass duct board holds moisture longer than metal, which makes it a favorite spot for mold to settle in. That's why on duct board jobs we don't stop at cleaning. We finish with Foster 40-20, a fungicidal coating made for HVAC systems that seals the board surface and blocks microbial growth from re-establishing.

The photo shows a full trunk run after coating — sealed end to end. If your AC has a musty smell on startup, this might be why.

Quick test for Katy homeowners: pull one supply register off the wall and shine your phone light inside.

If you see a fuzzy gray surface with dark speckling on it — that's fiberglass duct board, and that speckling is exactly what we found on a recent job in the area. Duct board can't be cleaned with the steel brushes used on metal duct; the wrong equipment tears the surface and puts fibers into your air.

We clean it with soft-bristle agitation and HEPA negative air, then seal it with Foster 40-20 antimicrobial coating so it stays clean.

That white coating isn't paint.

We just wrapped up a duct board job here in Katy, and the difference speaks for itself. The first photo is what years of dust and surface buildup look like inside fiberglass duct board. The second is the same system after cleaning and a full application of Foster 40-20 — an EPA-registered antimicrobial coating that seals the fiberglass and keeps mold from coming back.

If your home was built in the 80s, 90s, or early 2000s, there's a good chance you have duct board instead of metal duct. It needs a different cleaning approach, and most companies won't touch it.

We do. See the full job: https://airductcleaningkaty-tx.com/duct-board-cleaning-katy-tx/
