AC & Air Duct Mold Removal in New Caney, TX

Why does mold keep showing up on my New Caney vents?

Usually because the grilles are colder than the room air around them. When indoor humidity climbs, moisture condenses on the metal and on the drywall right beside it, and dust there gives mold something to feed on. Wiping the grille only buys time. The lasting fix is lower humidity, proper airflow and insulation on the duct boot behind the register. If spots return within weeks of cleaning, the assessor will want to look upstream at the coil, pan and duct runs in the attic, where most of the moisture originates.

Our area flooded in May 2024. Should the AC be checked?

If water reached the air handler, a floor return or ductwork, yes. Heavy rain in the Lake Conroe watershed flooded the Lake Houston area in May 2024, and New Caney residents were directed to the Montgomery County Disaster Recovery hotline for help. Caney Creek runs through the community. EPA's disaster guide says to assume mold growth when a home could not be dried within 24 to 48 hours, and ducts that held floodwater are often replaced rather than cleaned. Even without flood damage, a week of rain and a closed-up house can push indoor humidity high enough to wet a system.

Who does what on an AC mold job?

Texas splits the work. A mold assessment consultant inspects and writes a protocol listing the components to clean or remove, the containment and the clearance criteria. A separate company that holds a TDLR mold remediation license does the work, and the consultant comes back for the post-remediation assessment. An HVAC contractor often handles the equipment itself: a new pan, a cleaned or replaced coil, a corrected drain slope. Ask how the three will coordinate so the system isn't switched back on too early.

A note for New Caney

New Caney is unincorporated, about 30 miles from Houston, so building work runs through the Montgomery County Permit Department under Environmental Health, which keeps a separate East Montgomery County phone line. Its FAQ says substantially damaged structures in the floodplain need a Development Permit. The Montgomery County Public Health District does not list mold among the complaints it takes, so the assessment is private.
