AC and duct mold in Splendora tends to settle on the coil, in the drain pan, on sweating duct runs and around registers. Removal starts with stopping the moisture and continues with cleaning or replacing the contaminated parts under a Texas protocol.

Local conditions in Splendora
Splendora is a small city about 35 miles from Houston that grew around a railroad spur, and most of its residents live in areas the 2020 census classed as rural. The East Fork of the San Jacinto River runs nearby; during Harvey its floodwater swamped mobile homes near East River Road just outside the city, knocking some off their foundations, with one resident describing water rising about four feet in an hour. Homes that took water then may still have ducts or equipment that were never fully dried. Most AC mold here, though, comes from routine condensation in a humid climate: coils that stay wet for months, drain lines that clog, and attic or underfloor ducts that sweat.
Clean or replace?
| Component | Usually cleaned | Usually replaced |
|---|---|---|
| Supply and return grilles | Light surface spotting | Rusted or heavily stained grilles |
| Evaporator coil | Surface growth on intact fins | Corroded or flood-soaked coil |
| Drain pan | Plastic pan in good shape | Cracked or rusted metal pan |
| Flexible duct | Rarely | Growth on the inner liner |
| Sheet-metal trunk | Most cases, under containment | Crushed or floodwater-filled sections |
The mold assessment consultant's protocol makes the final call, and a separate company that holds a TDLR mold remediation license does the work.

Signs to watch
- Dark speckling on ceiling grilles or the drywall around them
- A sour smell for the first minute after the blower starts
- Water in the auxiliary pan or a dripping outdoor drain that has gone dry
- Insulation around a duct that feels wet
- Mildew on the closet door or walls around an indoor unit
- Rooms that stay sticky after the thermostat says they've cooled
A smell or a few spots don't prove the system is contaminated, and color says nothing about risk. A mold assessor can trace the source and decide whether sampling would add anything.
Timing and the seasons
Problems usually show up in late spring, when the system starts running long cycles, and peak through the humid summer. That is also when shutting the AC off is hardest, so ask about temporary cooling before work begins. Fall and the mild winter months are easier for duct replacement in a hot attic, and a pre-summer AC service that flushes the condensate line can head off the next round. Repairs inside city limits go through the City of Splendora Building Department at City Hall, with third-party building inspections.
