Environmental Medicine-Aware HVAC

Built for homes recovering from mold & CIRS exposure.

If you or a family member is working through CIRS (Chronic Inflammatory Response Syndrome) recovery with your physician, the building matters as much as the medicine. We specialize in the HVAC side of that equation — on-site mold testing, medical-grade filtration, verified humidity control, and post-remediation air quality confirmation — across Orange County.

We are HVAC and indoor air quality specialists, not a medical provider. Nothing on this page is medical advice or a claim to diagnose, treat, or cure CIRS or any condition. Always work with a licensed physician for medical decisions.

Why the building matters for CIRS recovery

Environmental medicine physicians treating CIRS routinely emphasize that recovery stalls if a patient returns to — or continues living in — a water-damaged building with an elevated mold burden. Standard HVAC service doesn't address this; a typical filter swap or refrigerant top-off does nothing for hidden moisture, biofilm on coils, or ductwork pulling in contaminated attic or crawlspace air. Getting this right requires testing first, then targeted changes to filtration, humidity, pressure balance, and duct integrity — which is where we specialize.

On-site mold testing — real data, not a guess

Rather than sending swabs to a lab and waiting a week or more, we run on-site qPCR testing (the same underlying method used for ERMI and HERTSMI-2 style panels) directly at your home. That means:

  • • Species-level mold identification, not just a spore count
  • • A same-visit baseline before we recommend any HVAC changes
  • • Re-testing after remediation or system changes to confirm the numbers actually improved
  • • Clear, physician-shareable reports if you're working through a CIRS protocol

The HVAC changes that actually move the needle

  • Humidity control below 50% RH: Dedicated dehumidification sized to your home — most mold species need sustained humidity above 55–60% to thrive, and Southern California's coastal humidity swings make this an easy thing to miss without measurement.
  • Medical-grade filtration: MERV 13+ or true HEPA bypass filtration where your system's static pressure allows it, sized correctly so airflow isn't choked.
  • UV-C and coil treatment: Targeting the wet coil surface where mold and biofilm actually grow inside the system itself — often an overlooked contamination source.
  • Duct sealing, or replacement when needed: Correcting leaky return ducts that pull unconditioned attic, crawlspace, or garage air — a common hidden contamination path even in homes that look clean. For duct-board or fiberglass-lined ductwork that's been contaminated, cleaning often isn't enough — mold can grow into the porous material itself, not just sit on the surface. In those cases we recommend replacing the affected sections rather than cleaning them.
  • Remediation-safe HVAC isolation: If you're mid-remediation, we seal supply/return registers in the containment zone and advise on negative-pressure setup so spores aren't pushed through the ductwork into the rest of the home.

Frequently asked questions

What is CIRS and why does it matter for my HVAC system?

CIRS (Chronic Inflammatory Response Syndrome) is a condition some physicians associate with prolonged exposure to water-damaged buildings and mold biotoxins. Homes that support CIRS recovery need verified low mold burden, tightly controlled humidity, and high-efficiency filtration — all things your HVAC system directly controls. We are not a medical provider and don't diagnose or treat CIRS, but we specialize in getting the building side of the equation right, working alongside your physician's environmental recommendations.

Do you test for mold, or just fix HVAC systems?

Both. We use a portable qPCR (ERMI/HERTSMI-2 style) testing device to identify and quantify mold species directly from your home, rather than relying on slower lab mail-in turnaround. This lets us verify a baseline, target remediation and HVAC changes to the specific species found, and re-test after work is complete to confirm improvement.

What HVAC changes actually help a mold-sensitive or CIRS home?

The big levers are: sealing and insulating ductwork so it isn't pulling in attic or crawlspace air, upgrading filtration (MERV 13+ or true HEPA where the system allows it), adding dedicated dehumidification to hold indoor relative humidity below 50%, UV-C or bipolar ionization at the coil to limit microbial growth on wet surfaces, and correcting any negative pressure in the home that draws in unconditioned, potentially contaminated air.

Can you help during active mold remediation, not just after?

Yes. During remediation we can help isolate the HVAC system from the work area (sealing returns/supplies in the containment zone), advise on negative-pressure setup so spores aren't pushed through ductwork into the rest of the home, and then handle post-remediation duct cleaning, filtration upgrades, and verification testing before you move back in.

Is this covered by insurance or a water-damage claim?

Sometimes, if the HVAC work is tied directly to a documented water-loss claim. We'll provide detailed, itemized documentation and testing data that you or your remediation contractor can submit to your insurer or public adjuster.

Do you work with my CIRS-literate doctor or environmental medicine physician?

We're glad to communicate directly with your physician's office or environmental consultant about the building-science side — humidity targets, filtration specs, and test results — so the medical and building teams are working from the same data.
