Commercial Hospital HVAC Compliance Systems in Orange

Hospitals in Orange operate under demanding clinical, safety, and energy requirements. Our Commercial Hospital HVAC Compliance Systems are engineered to help you meet code, maintain reliable room pressurization, and document performance so your teams can focus on patient care. As a family business of four generations with 80+ years in engineering, #1 AC Guys brings deep technical rigor to every healthcare project—from isolation rooms and procedure suites to imaging, pharmacy, and support spaces.

Codes and standards we design to

We build systems and documentation to align with leading healthcare requirements and local Orange/California enforcement.

• ASHRAE 170 ventilation strategies, air changes per hour, and pressure relationships
• California Mechanical Code and Title 24 energy standards for compliant, efficient design
• HCAI (formerly OSHPD) coordination, submittals, inspections, and closeout support
• Joint Commission expectations for environmental control, monitoring, and records
• NFPA-related ventilation considerations in healthcare environments

An engineering-led approach to compliance

Healthcare HVAC compliance is more than equipment selection—it’s the integration of airflow physics, controls, energy use, and evidence. Our process includes calculated ventilation rates, pressure zoning, and verifiable controls, with TAB and commissioning to prove results.

• Room pressurization maps for negative and positive spaces, with door swing and leakage considerations
• Air change rate design and verification, including occupied and setback modes where allowed
• Filtration strategy: MERV 13+ and HEPA integration, terminal or centralized as appropriate
• Temperature and humidity control aligned with space function (ORs, sterile storage, isolation)
• N+1 and fault-tolerant strategies where required to support continuity of care
• Sound/vibration mitigation, infection control coordination, and constructability planning
• Continuous monitoring, alarming, and trend logs for audit-ready records
• Energy optimization through heat recovery, demand control, and smart sequences

What we deliver for hospitals and healthcare campuses

• Design-build and plan/spec execution with sealed drawings and coordinated submittals
• Retrofits and expansions: isolation rooms, pharmacy, imaging suites, clean support spaces
• Operating room ventilation improvements, laminar strategies as specified
• HEPA fan filter units, terminal boxes, and pressurization control packages
• Energy recovery ventilators (ERV/HRV) and high-efficiency make-up air
• Chilled/hot water, DX, and hybrid systems sized for healthcare duty
• VRF/mini-split solutions for non-critical areas and auxiliary spaces
• BAS integration, point-to-point checkout, alarming, and trending
• Testing, Adjusting, and Balancing (TAB), functional performance testing, and commissioning
• O&M manuals, training, and turnover binders designed for inspections

Documentation and inspection readiness

From design through turnover, we focus on traceable compliance. Expect ventilation schedules, sequences of operation, control matrices, and balanced reports that match what inspectors and surveyors request. We coordinate with HCAI field staff and your IOR, support change documentation, and provide trend logs to demonstrate performance over time.

Equipment expertise and sourcing

Our team is factory-trained at Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Hier (China). When specified, we source equipment and controls through AC PRO to meet project standards and lead-time targets, aligning submittals with your facility’s approved product lists.
