Mold

Q: I think there's mold in my HVAC system. Should it be tested before any work is done?

Yes, and testing is a job for a licensed mold inspector. We work with several licensed mold inspectors and environmental testing companies in Central Texas. If you don't have one yet, we'll refer you to someone who can do air sampling and surface testing and write a protocol before any remediation begins.

Q: What does HVAC mold remediation cost?

It depends on how far the mold has spread, which parts are affected (coil, air handler, drain pan or ducts) and what the protocol requires. We give a free estimate with a clear scope of work before anything starts.

Q: How do I know if there's mold in my HVAC system?

The usual signs are a musty smell when the system runs, dark growth on the vent covers or the air handler, and standing water in or around the drain pan. A licensed mold inspector can confirm it with air or surface sampling. If you notice any of these, call us at 512-489-4653 to have the air handler, coil and drain pan looked at.

Q: Do you work with insurance claims?

Yes. Insurance sometimes covers HVAC mold remediation when the mold comes from a covered water loss. We provide scoped documentation to support your claim; the coverage decision is your insurer's.

Q: What areas do you serve?

Austin and nearby Central Texas towns, including Buda, Kyle, Cedar Park and Round Rock.

Mold in your AC system or ductwork? Gold Eagle Services is a licensed Texas mold remediation company that handles HVAC mold: the air handler, evaporator coil, drain pan and ducts. On a larger project, we do the HVAC scope of the remediation protocol alongside the licensed mold remediation contractor who leads it. Mold in walls, attics or belongings goes to a general mold remediation company.

Why HVAC Mold Work Takes Two Texas Licenses

Texas licenses air conditioning work and mold remediation separately, and mold inside an AC system needs both. The TACLA license (Air Conditioning Contractor) covers opening the system: the air handler, the coil compartment, the plenums and the ductwork. The RCO license (Mold Remediation Company) covers applying biocides, treating contaminated surfaces and carrying out a mold remediation protocol.

Gold Eagle Services holds both:

RCO1783: Texas Mold Remediation Company License
TACLA119235: Texas Air Conditioning Contractor License

Before you hire anyone for HVAC mold work, ask for both license numbers and look them up at tdlr.texas.gov.

Mold on the Evaporator Coil & Air Handler

In most Austin homes the air handler sits in the attic, and its evaporator coil sweats water through the whole long cooling season. Dark, damp and fed humid air on every cycle, it is exactly where mold takes hold. Mold that grows here rides the airflow into every duct each time the system runs. Treating it properly means opening the coil compartment and following a documented treatment protocol.

Mold in Ducts & Plenums

Mold can grow inside supply ducts, return ducts and the ductboard plenum boxes of an attic system long before it shows at the registers. When a mold inspection or environmental assessment finds it in the ducts, the protocol usually calls for opening the affected sections, HEPA vacuuming, treating the surfaces and, in severe cases, replacing the duct. We handle the mechanical access and the HVAC-side work the protocol assigns to us, and coordinate with the mold remediation contractor who leads the project.

Drain Pan, Condensate & the Moisture Source

Standing water in the drain pan is one of the most common ways mold starts inside an air handler. A clogged drain line, a failed float switch or a pan pitched the wrong way keeps that water sitting there, and the mold comes back even after remediation. That is why we fix the moisture source along with the mold.

For Mold Remediation Contractors: the HVAC Scope

If you’re a mold remediation contractor (MRC) with a protocol that includes HVAC scope, send it to us. We review the protocol, quote the HVAC portion as its own scope, and do the mechanical side of the remediation, so you aren’t subcontracting that part blind. When post-remediation verification or clearance sampling is part of the protocol, we work alongside the environmental consultants and testing companies doing it across Central Texas. More on how we work with MRCs: HVAC scope for mold remediation contractors.

Frequently Asked Questions

Can I get a quote on just the HVAC scope of my remediation protocol?

Yes. Send the protocol over and we'll review the HVAC scope, ask any clarifying questions, and set up a free on-site inspection if needed. We work within an existing protocol and coordinate directly with the MRC or environmental consultant managing the project.
