Fresno AC mold usually develops where cold, wet parts meet humid air: the evaporator coil, the drain pan, attic ductwork that sweats, and supply registers. Under Texas law a mold assessor scopes the job and a different company removes the growth, while an HVAC contractor often fixes the source.

Local conditions in Fresno
Fresno is an unincorporated community in eastern Fort Bend County, about 17 miles from downtown Houston, on FM 521 at the Brazoria County line. Large bedroom-community subdivisions such as Teal Run, Winfield Lakes, NewPoint Estates, Andover Farms and Cambridge Falls have been built over former forest and grazing land. Many of these homes put the air handler and duct runs in the attic. Newer construction is often tighter, which keeps cool air in but can also hold moisture inside when the system is oversized or the drain line clogs.
Fort Bend County points residents to FEMA's Flood Map Service Center to check whether a property is in a flood hazard area. Any home where water reached floor registers or a return should have those parts inspected.
Who does what
| Role | What they handle | Notes |
|---|---|---|
| Mold assessment consultant | Inspection, written protocol, post-remediation assessment | Must be a different company from the remediator on the same project |
| Mold remediation company | Containment, cleaning, removal of contaminated duct and parts | Writes a work plan that meets the protocol |
| HVAC contractor | Drain line, pan, insulation, equipment repairs | Fixes the moisture so mold doesn't return |
| Homeowner | Small surface cleaning, humidity control, keeping records | May clean their own home without a TDLR license |
Signs to look for
- A musty odor in the first minutes after the system starts
- Black or gray dots on supply diffusers and the ceiling around them
- Rust or water in the pan under the attic unit
- Rooms that feel damp even when the thermostat is satisfied
Timing
Problems peak in the long summer, when the system runs almost constantly. Schedule the assessment early, since EPA advises against running a system you suspect is contaminated. Keep indoor humidity below 60 percent while you wait. If work afterward involves modifying an existing building of 400 square feet or more, or any work in a floodplain, Fort Bend County Engineering issues the development permit for unincorporated areas. Fort Bend County Health & Human Services lists mold complaints among services it does not provide, so a mold assessor is the right first call.
