Commercial Hospital HVAC Sterilization in Orange, CA

Hospitals and healthcare campuses in Orange depend on precise HVAC sterilization to help control airborne pathogens, protect patients and staff, and sustain continuous operations. #1 AC Guys brings deep commercial expertise to these critical environments, combining engineering rigor with field‑proven installation, commissioning, and maintenance.

Our fourth‑generation family company focuses on one mission: healthy air for healthier lives. With 80+ years of engineering experience, we deliver hospital‑grade solutions that integrate advanced filtration, disinfection, pressure control, and smart monitoring—tailored to each room’s clinical purpose and your compliance requirements.

What we engineer and service

• HEPA and ULPA air filtration banks with validated seals and low‑leak housings
• UV‑C germicidal irradiation for coils and airstream sterilization
• Negative and positive pressure rooms (AIIR/ISO, OR, sterile storage)
• Temperature and humidity control for ORs, pharmacies, and labs
• Dedicated outdoor air systems with energy recovery (DOAS/ERV)
• Room pressure monitors, alarms, and trend logging
• Redundant fans, isolation dampers, and emergency bypass strategies
• Air change rate optimization and zoning for acuity‑based areas
• Sealed ductwork, cleanable plenums, and antimicrobial drain strategies

We design to meet or exceed applicable healthcare guidelines such as ASHRAE 170 and industry best practices, and we coordinate with your compliance team for FGI, CDC recommendations, and California authorities as required. Our field teams work discreetly in live patient environments, with infection‑control barriers and shift scheduling to minimize interruptions.

AC PRO equipment options and multi‑brand integration

On request, we supply and integrate AC PRO equipment and accessories within new or existing systems. We also optimize mixed‑brand facilities, ensuring components operate cohesively—fans, coils, filtration racks, UV‑C arrays, and controls tuned to your clinical and energy objectives.

Our engineers are factory‑trained by Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China), enabling precise design and service across variable‑refrigerant, split, and hybrid systems frequently used in non‑sterile areas and support spaces.

Technologies that raise the standard

• Filtration: H13/H14 HEPA and ULPA with scan testing and gasket verification
• Disinfection: UV‑C coil irradiation and in‑duct arrays sized for contact time
• Airflow control: smart VAV/VVF, pressure‑independent control valves, and ECM fans
• Monitoring: continuous differential pressure, ACH, RH/°F, and alarm integration
• Resilience: N+1 fan arrays, quick‑swap filters, and maintainable coil access
• Efficiency: demand‑based ventilation, heat recovery, and advanced economizer logic

Every design is documented with sequences of operation, commissioning checklists, and owner training, so your facility team can maintain consistent, verifiable performance.

Our process in Orange, CA

1) Assessment and compliance mapping: we survey spaces, identify clinical use cases, and align targets for pressure, ACH, temperature, and humidity.
2) Engineering and submittals: sealed drawings, equipment schedules, and sequences of operation with clear verification points.
3) Clean installation: infection‑control measures, work‑area containment, and sterile handling of filters and coils.
4) Commissioning and validation: instrumented testing, balancing, and functional performance tests—plus staff handoff.
5) Continuous care: 24/7 service, PM programs, and rapid‑response containment when conditions change.

Rapid response and maintenance

Healthcare never sleeps. Our Orange‑based crews provide 24/7 emergency support, from restoring room pressurization to addressing alarm conditions. Planned maintenance includes filter changes, UV‑C efficacy checks, coil hygiene, sensor calibration, and verification of alarms, safeties, and setpoints.
