In Webster, AC mold most often grows on the coil, in a drain pan that holds water, and on ducts and registers that sweat in humid Clear Lake air. A mold assessor inspects the system and writes a protocol, and a different company cleans or replaces what is contaminated once the moisture is fixed.

Local conditions
Webster is a bedroom community about 26 miles from downtown Houston, tied closely to the Clear Lake area and the high-tech industry that grew up around NASA's Johnson Space Center. Clear Creek forms its southeastern border, which is also the Harris County and Galveston County line. Interstate 45 runs through town, with Baybrook Mall just across the line in Houston. The air here is humid most of the year, and homes and apartments alike keep their AC running for months at a stretch.
That steady cooling makes the usual trouble spots predictable, whether the system is original to the house or a recent replacement: a condensate line that clogs, a pan that stays wet, flex duct that sweats in the attic, and ceiling registers that collect droplets on muggy afternoons. In apartments, a stacked closet unit with a shared drain can back up into more than one ceiling. The fix in every case starts with the water, not the spots.
Inspection or testing?
| Mold inspection (assessment) | Mold testing (sampling) | |
|---|---|---|
| What it does | Looks at the coil, pan, ducts and registers and finds the moisture source | Collects air or surface samples for a lab |
| When it helps | Nearly always the first step | When growth is hidden, or to check cleaning afterward |
| EPA view | Fixing moisture is the key to mold control | Usually unnecessary when mold is visible; no federal limits exist |
| Typical cost | Angi's Houston cost data: about $453 on average for inspection and testing; Angi national figures add $50 to $75 for an HVAC sample | |

Signs to watch for
- A sour or earthy smell when the air handler starts
- Gray or black spotting on diffusers in the same rooms each summer
- Water on the closet floor under the unit
- Peeling paint or stains around registers
Seasonal notes
Spring and early summer are good times to schedule an inspection, before the system runs nonstop. EPA advises against running a system you suspect is contaminated, which is hard to do in August. If ceiling drywall or other parts of the building need replacing afterward, the City of Webster Building Division handles permits and inspections. Renters can report violations through the Building Division; Webster's adopted codes include the International Property Maintenance Code.
