AC and duct mold in Rosharon most often forms on the coil, in a drain pan that holds water, on sweating ducts and around supply registers. Removal means stopping that moisture, then cleaning or replacing contaminated parts under a Texas protocol and confirming clearance. Call the number on this page to be connected with a local mold remediation company in Rosharon.

What happens when you call
The number connects you with an independent local company. They will ask what you've noticed: grille spotting, a smell at startup, water near the indoor unit or a ceiling stain. A mold assessment consultant then inspects the air handler, coil, pan, condensate line and reachable ducts, and writes a protocol before any removal begins. Texas law requires that a different company, one holding a TDLR mold remediation license, perform the removal. The consultant returns for the post-remediation assessment, and you should end up with a Certificate of Mold Damage Remediation.
What drives the price
- Extent. Grilles and a pan are a modest job; mold through the blower and trunk lines is a large one.
- Replacement. Moldy flex duct and storm-damaged equipment usually get replaced.
- Access. Attic clearance and rural travel distance add time.
- HVAC repairs. Drain corrections, pan replacement or coil work, usually by an HVAC contractor.
- Assessment. The consultant's protocol and clearance are billed separately.
National ranges (HomeGuide, 2026) list $2,000 to $10,000 for HVAC system or duct mold work.

Rosharon conditions
Rosharon is an unincorporated, rural community in Brazoria County, about 28 miles from Houston, at FM 521 and FM 1462, with farming history and newer subdivisions such as Savannah Plantation, Sterling Lakes and Southern Colony. Chocolate Bayou lies west of some neighborhoods along FM 1462. Hurricane Ike in 2008 damaged the area known as Little Cambodia, and Harvey damaged it again. Storm-driven roof leaks can reach attic ducts and air handlers, but most AC mold here grows from routine condensation during long, humid summers, especially in homes where the condensate line has never been flushed. Brazoria County Floodplain/911 Administration issues building permits for the unincorporated area and determines whether a property sits in a FEMA flood hazard area; allow up to 20 business days for a permit.
Checklist before the company arrives
- Turn the system off if mold inside it is suspected, as EPA recommends.
- Check that the outdoor condensate line is dripping.
- Photograph stains, wet insulation and the pan if reachable.
- Look both companies up on TDLR's license search.
- Write down when the smell or spots first appeared and any storm or roof repairs since.
- Move stored boxes away from the attic hatch and the equipment.
