Air Vent Cleaning in Houston, TX

What waiting on vent cleaning actually costs you

A disconnected branch run in a Houston attic dumps conditioned air into blown insulation. The jacket sweats. Insulation stays damp through August. Ceiling stains show up months later. Rodent and insect intrusion in attic flex is common here, and the blower pushes whatever is in there into the bedrooms. That is the real stake. Not dust on a register grille.

The work differs by duct type. Insulated flex on sheet-metal or ductboard plenums, standard from the 1980s on, has a thin inner liner that tears under aggressive brushing. Sagging loops hold the settled dust, so those get addressed first. Round galvanized and rigid fiberglass board trunks in 1950s–70s houses take different tooling. Rusted or corroded ductboard at the plenum cannot be cleaned back to new.

Odor usually starts at the coil and drain pan, not the runs. Constant latent load here keeps the pan wet. Skip that and the smell returns.

Pull one register and look down. Gray fuzz in the low loops. A torn outer jacket. Compressed insulation. Three to five years is the normal interval, sooner after flooding, remodeling, roof work, pets or smokers.

If the liner is shredded and the run is kinked, cleaning it is wasted motion. Replacement is the honest answer.
