Professional HVAC Mold Remediation Services in Waco, TX
Mold inside an HVAC system can spread to new areas each time the system cycles on. Our pros remove the growth and address the moisture that caused it. We start by inspecting the HVAC system to find where mold is growing and how far it has spread. We explain each step so you know what to expect. We then run HEPA air scrubbers to capture airborne spores during the work. We treat the HVAC surfaces with antimicrobial solutions that help slow regrowth. A final walkthrough confirms the treated areas are dry and free of visible growth. The specific HVAC mold remediation services we provide for residential and commercial properties are listed below.
Air Duct Mold Remediation in Waco
Condensation forms inside ducts when cold supply air runs through humid attics, and dust on the duct walls gives mold a food source. Waco Air Duct Cleaning Pro runs a camera through each supply and return branch to mark where growth appears and how far it extends. Our HVAC duct cleaning team isolates affected runs, places the system under negative pressure with a HEPA collection unit, and brushes the growth off metal duct surfaces. After cleaning, an EPA-registered antimicrobial labeled for HVAC use goes on the cleaned surfaces. Flex duct with growth inside its inner core gets replaced, since that material cannot be cleaned reliably. Musty odors fade, and the ducts deliver air without carrying spores into living spaces.
HVAC Mold Removal in Waco
The air handler cabinet stays dark and damp during cooling season, and mold often grows on its interior insulation, blower housing, and fan wheel. Our air duct cleaning services technician shuts off power, opens the cabinet, and inspects every interior surface with a light and camera. Containment around the air handler closet keeps disturbed spores from reaching nearby rooms. We remove the blower assembly and clean the wheel and housing with brushes, a HEPA vacuum, and a cleaner approved for HVAC components. Fiberglass cabinet liner with visible growth gets cut out and replaced with new foil-faced insulation. Cleaned metal surfaces receive an EPA-registered antimicrobial before reassembly. The blower stops spreading spores, and the air handler runs with a clean interior.
HVAC Mold Cleaning Service in Waco
Supply registers and boots sweat when cold air meets humid room air, and dark spots form on the grille and the ceiling around it. Our home air duct cleaning team removes each affected grille and inspects the boot and the first few feet of duct behind it. Grilles get washed with a mold cleaning solution and dried before reinstallation, or replaced when rust has set in. We clean the boot interior, apply an antimicrobial, and seal the boot to the drywall with mastic so humid ceiling air stops reaching the cold metal. Missing insulation on the attic side of the boot gets replaced. The spots stop coming back, and the vents look clean against the ceiling.
Evaporator Coil Mold Cleaning in Waco
The evaporator coil stays cold and wet whenever the AC runs, and mold grows between its fins where airflow carries in dust. Our team inspects the coil face with a light and camera to check how deep the growth reaches into the fins. We apply a foaming coil cleaner that lifts growth from between the fins, then rinse the coil with low-pressure water that drains into the pan. Heavily fouled coils get a second cleaning pass and a fin comb to straighten bent fins. A UV-C light can be installed afterward to keep the coil clear of new growth. The coil transfers heat better, and the air leaving the system smells clean.
Drain Pan Mold Treatment in Waco
Standing water in a clogged or rusted drain pan feeds mold and slime that spread odors into the air handler. Our commercial air duct cleaning team checks the pan for standing water, rust holes, and biological buildup, then tests the condensate line for clogs. We clear the drain line with a wet vacuum, scrub the pan, and treat it with an EPA-registered antimicrobial. Rusted metal pans get replaced with a corrosion-resistant pan sized to the air handler. The technician confirms the pan slopes toward the drain and installs a float switch when one is missing. Drain tablets go in to slow new slime growth in the line. Water drains out with every cycle, and the pan stops feeding growth inside the unit.
Duct Board and Liner Replacement in Waco
Fiberglass duct board and internal duct liner absorb moisture and hold mold inside their fibers, where cleaning cannot reach it. Our air duct replacement technician inspects these materials with a camera and probes suspect areas for dampness. Following NADCA guidance, we remove porous duct materials that show mold growth instead of cleaning them. The crew bags removed material inside containment and carries it out sealed. We replace duct board plenums with sheet metal or new duct board and replace lined sections with metal duct wrapped in exterior insulation. Every new joint gets sealed with mastic to keep humid air out of the replaced section. The new materials start clean, and the growth hidden inside the old fibers is gone.
Return Plenum Mold Remediation in Waco
Return plenums in closet platforms and wall cavities pull in humid air through gaps, and mold grows on the wood framing, drywall, and duct board around them. Waco Air Duct Cleaning Pro removes the return grille and filter and inspects the plenum interior with a camera and moisture meter. We set up containment, remove moldy drywall or duct board, and HEPA vacuum the framing. Wood surfaces get cleaned and treated with an EPA-registered antimicrobial before the plenum is rebuilt with sealed sheet metal or new duct board. Every seam gets sealed with mastic so the return draws air only through the grille. The return stops pulling spores into the system, and the closet stays dry.
Moisture Source Correction in Waco
Mold returns quickly when the moisture that fed it stays in place, so remediation has to include the source. Our technician measures indoor humidity, supply air temperature, and duct surface temperatures to find where condensation forms. Common sources include sweating ducts with thin insulation, leaky return plenums, oversized AC units that short-cycle, and blocked drain lines. We fix the source by sealing duct leaks, adding insulation, clearing drains, or recommending a whole-home dehumidifier when humidity stays high. Our indoor air quality improvement approach explains each source in your report so you know what caused the growth. A follow-up humidity reading confirms the correction, and treated surfaces stay clean.
