Commercial Hospital & Lab Ventilation in Orange, CA

At #1 AC Guys, our mission is healthy air for healthy lives. For hospitals, clinics, pharmacies, and laboratories in Orange, CA, that means ventilation systems engineered to maintain precise air changes, pressure relationships, temperature, and humidity—24/7. We combine design-build delivery with rigorous commissioning so your environment performs as modeled and stands up to audits.

What we deliver

• Hospital ventilation systems: isolation rooms (AIIR), protective environments (PE), operating rooms, ICUs, pharmacies, and imaging suites
• Laboratory ventilation: fume hoods, snorkels, biosafety cabinets support, general lab exhaust, and make-up air
• Cleanrooms: ISO 5–8 layouts, gowning/ante rooms, cascading pressure, HEPA/ULPA, and low-leakage envelopes
• Pressurization control: stable negative/positive zones with continuous monitoring and alarms
• Filtration and disinfection: high-MERV, HEPA, ULPA, UV-C, and air quality sensing for verification
• Controls & integration: BAS/BMS, room pressure monitors, VAV/VRF/VFD strategies, fault detection and diagnostics
• Commissioning & TAB: full functional testing, balancing, verification reports, ongoing re-commissioning
• Maintenance & emergency: planned PM programs, uptime SLAs, and 24/7 rapid response

We serve new builds, renovations, and fast-track compliance upgrades. Whether it’s a negative-pressure isolation wing or a GMP cleanroom, our team delivers precise airflow and measurable results.

Compliance and standards we align with

Our designs and submittals are crafted to meet applicable codes and standards, including ASHRAE 170 for healthcare ventilation, FGI Guidelines, California Title 24, NFPA 99 for healthcare facilities, USP 797/800 for compounding pharmacies, ISO 14644 for cleanrooms, and CDC/NIH recommendations for laboratories. For hospitals in California, we support HCAI processes and documentation as required.

Design-build engineering that reduces risk

We start with a detailed needs assessment and airflow strategy: target ACH, pressure relationships, filtration tiers, heat loads, and redundancy. We then select equipment, controls, and distribution methods that fit your space and lifecycle cost goals. Our teams coordinate with infection control and EH&S to maintain operations during phased work, using temporary pressurization and containment where needed.

• CFD-informed layouts for critical spaces
• Low-leak ductwork, room envelope sealing, and vestibule design
• Energy optimization with heat recovery, VFDs, economizers, and demand control
• BAS dashboards with room pressure and ACH display for staff confidence

AC PRO equipment options

When your project calls for specific product ecosystems, we can source and integrate AC PRO packaged units, air handlers, ventilation accessories, and compatible controls to meet performance, budget, and lead-time targets. We evaluate every selection for airflow stability, filtration capability, serviceability, and long-term cost.

Factory-trained expertise

Our engineers are factory-trained by Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China). This background helps us commission complex systems with precision, integrate advanced controls, and verify performance under real operating conditions.

Commissioning, TAB, and verification

We execute comprehensive commissioning and test-and-balance to validate air changes per hour, fume hood face velocity, room pressurization, filtration performance, and alarms. Clear reports support internal QA, accreditation, and regulatory reviews. We also offer periodic re-commissioning to maintain performance over time.

Service area and response

Based in Los Angeles and serving Orange, CA and all of Orange County, we also cover Los Angeles County, Ventura County, and Western Riverside County. Our healthcare and lab clients count on us for rapid dispatch, stocked service vehicles, and senior engineering oversight on every critical call.
