Commercial Hospital & Lab Ventilation in Los Angeles

When patient outcomes, research integrity, and regulatory compliance are on the line, ventilation is a mission‑critical system. #1 AC Guys delivers hospital and laboratory ventilation in Los Angeles with a design‑first approach that addresses air changes per hour, contamination control, redundancy, and energy performance without compromising uptime. Our 4th‑generation team brings 80+ years in engineering to plan, execute, and maintain systems that meet healthcare and lab standards in the real world.

Standards and compliance expertise

We engineer to the codes and guidelines your facility depends on: HCAI (formerly OSHPD) requirements, ASHRAE 170, NFPA 99 and NFPA 45, USP 797/800 for sterile compounding, ISO 14644 for cleanrooms, ANSI Z9.5 for laboratory ventilation, California Title 24, CALGreen, CBC seismic restraint, and local jurisdictional requirements. Our team manages drawings, submittals, HCAI coordination, inspections, and closeout documentation to keep your project moving.

Spaces we serve

• Operating rooms, procedure rooms, sterile corridors, and sterile processing
• Negative and positive pressure isolation rooms with anterooms
• Pharmacies and cleanrooms supporting USP 797/800
• Clinical labs, BSL‑2/3 research suites, and vivaria
• Chemical fume hood and specialty exhaust systems
• Imaging, dental, ambulatory care, and outpatient facilities

Systems and technologies

We design and integrate solutions including HEPA/ULPA terminal filtration, pressure control with room‑to‑room cascades, VAV and airflow tracking, ERV/energy recovery, dedicated outdoor air systems, humidity control, and BACnet‑based building automation with alarms and trending. Our team delivers Daikin‑compatible ventilation and VRV/VRF integration where appropriate, alongside other leading technologies, to balance reliability, maintainability, and lifecycle cost.

• High‑efficiency HEPA arrays and ceiling grid integration
• Direct pressure monitoring with local and central displays
• Redundant fans and N+1 strategies for critical areas
• Seismic bracing and OSHPD/HCAI anchorage details
• Corrosion‑resistant materials and cleanable duct design
• MERV 13–16 pre‑filtration upstream of HEPA

Delivery methods that fit your project

Whether design‑build, plan‑and‑spec, or fast‑track retrofit, we coordinate with architects, infection prevention, facilities, and commissioning agents from concept through turnover. Our constructability reviews de‑risk installation; our pre‑functional checklists and TAB confirm performance; our trending and acceptance testing document compliance and set your team up for smooth operations.

Commissioning, TAB, and validation

We provide room pressurization verification, air change and cascade testing, filter integrity checks, controls calibration, and seasonal performance reviews. Our technicians complete balancing for supply, return, and exhaust, validate alarms and interlocks, and generate as‑built documentation your clinical and EHS teams can rely on.

Operations and maintenance

Post‑project, we support your facility with preventive maintenance, sensor recalibration, filter replacement strategies, and emergency response. We can integrate continuous IAQ metrics and pressure alarms so facilities teams see issues early and act fast, minimizing downtime in critical spaces.
