AC & Air Duct Mold Removal in Porter, TX

What to expect when you call

The call puts you in touch with an independent local company. Have a few details ready: where the growth or smell is, whether water has leaked from the unit or a ceiling, how old the system is, and whether the house has flooded. On a hired project, Texas requires a mold assessment consultant to inspect and write a protocol before any removal. The removal itself goes to a separate company that holds a TDLR mold remediation license, and the consultant returns afterward to confirm clearance.

What sets the price

• Scope. Growth limited to grilles and a pan is a small job; growth on the blower and through trunk lines is not.
• Duct type. Moldy flex duct is usually replaced; sheet metal can often be cleaned.
• Access. Low attic clearance, blown-in insulation and summer heat add labor.
• Flood history. Equipment or ducts that took water may need full replacement.
• The assessor. Texas law makes the consultant's protocol and clearance visit a second bill.

National ranges (HomeGuide, 2026) put HVAC system or duct mold work at $2,000 to $10,000. Angi's Houston cost data reports inspection and testing averaging $453.

Local conditions in Porter

Porter is an unincorporated community about 24 miles from Houston, loosely defined by ZIP code 77365, along I-69 and FM 1314 where the Grand Parkway crosses. During Harvey, Montgomery County received about 36 inches of rain, Peach Creek ran out of its banks, and a Porter resident died when a tree fell on her home. Storm-damaged roofs let rain reach attic ducts and air handlers, and wet insulation around a duct holds water against it for weeks. Day to day, the bigger driver is humidity: a long cooling season, ducts in hot attics and drain lines that slowly clog. Replacement work in unincorporated Porter goes through the Montgomery County Permit Department, which keeps a separate East Montgomery County phone line.

Checklist before anyone arrives

• Turn the system off if you suspect mold in it, following EPA's advice.
• Clear the path to the air handler, attic hatch and outdoor drain outlet.
• Photograph stains and any water near the unit.
• Look up both companies on TDLR's license search.
• List storm or roof repairs since you moved in.
