Commercial Hospital HVAC Compliance Systems in Los Angeles

What We Deliver

Hospitals and healthcare campuses in Los Angeles demand HVAC systems that are precise, resilient, and compliant. #1 AC Guys specializes in commercial hospital HVAC compliance systems built for critical environments: operating rooms, isolation rooms (AIIR/negative pressure), ICUs, NICUs, sterile processing, cleanrooms, and pharmacies. We design for pressurization, temperature, humidity, filtration, airflow rates, and controls that support clinical needs—without compromising energy performance or uptime.

• Design-build and plan/spec execution for new builds, expansions, and retrofits
• Compliance alignment with ASHRAE 170, California Mechanical Code, Title 24, and HCAI (formerly OSHPD) expectations
• HEPA and final filtration strategies, UV-C integration, and air change rate optimization
• Negative/positive pressure room controls with continuous differential pressure monitoring
• N+1 redundancy planning for fans, coils, and critical components
• BMS integration, IoT sensors, analytics, and alarm strategies
• Commissioning, TAB, validation testing, and documentation
• Preventive maintenance, retro-commissioning, and 24/7 emergency response

Compliance and Standards We Address

We engineer systems to align with core healthcare standards and local authority requirements. Our process incorporates ASHRAE 170 ventilation guidelines for healthcare facilities, the California Mechanical Code, California Title 24 energy standards, and HCAI (formerly OSHPD) expectations for healthcare construction and alterations. We also prepare documentation and performance data to support inspections and Joint Commission readiness. Your Authority Having Jurisdiction (AHJ) makes final approvals, and we help you arrive prepared.

Systems and Technologies

We implement robust air-handling and control strategies tailored to each clinical space and risk level.

• Air Handling Units (AHUs) with staged filtration up to HEPA, UV-C irradiation options, and cleanable, low-leak casings
• Pressure zoning for OR suites, isolation rooms, sterile corridors, and clean/dirty workflows
• High-accuracy sensors for temperature, humidity, and differential pressure with real-time dashboards
• VAV and hydronic systems with VFDs for precise flow, energy savings, and stable setpoints
• Redundancy and fault-tolerant design (N+1 fans, dual power, bypass and isolation strategies)
• Sealed ductwork standards, low-leak valves, and room envelope coordination to maintain setpoints
• BMS integration and alarms for excursions, filter loading, and trend analytics

Our factory-level training with Fujitsu (Japan), Mitsubishi Elektrik (Thailand), Midea (China), Gree (China), and Hier (China) strengthens our engineering insights and commissioning rigor. This background supports dependable, repeatable performance in complex healthcare environments.

Process: From Assessment to Validation

Every hospital and clinic is unique. We start with a compliance and risk assessment, review drawings and clinical workflows, and capture existing performance via TAB and data logging. Then we model loads and airflow, engineer sequences of operation, and coordinate with your facilities, infection prevention, and construction teams.

• Assessment and basis of design (BOD) aligned to clinical use and code
• Detailed engineering, submittals, and controls narratives
• Installation with infection control risk assessment (ICRA) best practices
• Commissioning and functional performance testing
• Independent TAB, pressure mapping, and reporting
• Training for facilities staff, O&M manuals, and turnover documentation
• Ongoing monitoring, preventive maintenance, and retro-commissioning

We emphasize clarity and documentation so your team can demonstrate compliance and maintain stable operation long after project closeout.
