Commercial Hospital & Lab Ventilation — Los Angeles (Carrier)

Engineered Ventilation for Healthcare and Research

We build hospital- and lab-grade ventilation systems that deliver the exact airflow, pressure relationships, and filtration your facility demands. Whether the need is new construction, a complicated retrofit in an active wing, or rapid compliance upgrades, our engineers design around Carrier commercial air handlers, chillers, and rooftop units to achieve stable, measured results.

• Pressure control: negative for isolation and BSL spaces; positive for ORs and cleanrooms.
• Air changes per hour tuned to room classification and usage.
• Filtration strategies: MERV 13+ prefilters, HEPA terminal boxes, and optional in-duct UV-C.
• Controls: BAS/BMS integration, VAV and terminal devices, demand control ventilation, and trend logging.
• Commissioning and TAB to validate design intent and document compliance.

We coordinate closely with facilities, infection prevention, risk management, GCs, and AHJs to maintain safety and continuity throughout the project.

Carrier-Focused Capabilities

Our team services and integrates Carrier commercial equipment across hospitals, clinics, universities, biotech, pharma, and analytical labs. From air handlers and RTUs to hydronics and controls, we optimize each component for reliability and energy performance while preserving clinical outcomes.

• Design and retrofit of Carrier AHUs and rooftop units with energy recovery, economizers, and optimized fan arrays.
• Chiller/boiler plant ventilation interfaces and coil selections to control humidity and temperature tightly.
• BAS integration via open protocols for alarms, trending, and remote diagnostics.
• Lifecycle planning: filtration schedules, sensor calibration, and spare-parts strategies to minimize downtime.

We document before/after conditions, provide operator training, and set clear KPIs so your team can sustain performance.

Codes, Standards, and Best Practices

We design to meet or exceed applicable guidance for healthcare and laboratories, including ASHRAE 170 and 62.1, CDC recommendations, USP 797/800 for sterile compounding, NFPA 45/99, California Title 24 energy code, and HCAI (formerly OSHPD) requirements where applicable. Our submittals outline ACH, pressure relationships, filtration ratings, and control sequences in plain language, backed by calculations and cut sheets.

• Isolation rooms: verified negative pressure with continuous monitoring and alarms.
• Operating rooms: positive pressure, targeted temperature/humidity, low-turbulence diffusion.
• Cleanrooms and labs: room pressurization cascades, HEPA terminal filtration, and air-tight envelope coordination.
• Fume hood exhaust and make-up air balancing with diversity factors for real-world operation.

Every project concludes with TAB reports, sensor calibration certificates, and O&M packages tailored for your staff.

Why #1 AC Guys

• 80+ years of engineering heritage from a 4th‑generation family of engineers.
• Proven delivery on large and complex healthcare and research projects across Southern California.
• Factory training completed at Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China).
• Mission-driven focus on healthy air that protects patients, clinicians, and researchers while lowering lifecycle costs.
• Transparent process, measurable outcomes, and responsive local support.

We bring the discipline of engineering to every decision—airflow math, controls logic, and constructability—so you get predictable results the first time.

Our Process

• Assessment: site walk, data logging, and review of drawings and compliance requirements.
• Engineering: load calculations, airflow zoning, filtration strategy, sequence of operations, and submittals.
• Installation/Retrofit: phased execution to protect operations, infection control measures, and interim pressurization.
• Commissioning & TAB: verification of ACH, pressures, alarms, and controls sequences with signed reports.
• Training & PM: operator training, spare parts lists, IAQ monitoring plans, and scheduled maintenance.

After turnover, our service team continues with seasonal optimization, filter and belt changes, calibration, and analytics-backed performance reviews.

Energy and IAQ Optimization

We help you meet both clinical targets and energy mandates. Strategies include energy recovery ventilators, right-sized ventilation rates with occupied/unoccupied modes, smart reheat control, and demand control ventilation where allowed. Our approach aligns with Title 24 without compromising patient safety or research integrity.

Service Area

We serve Los Angeles County and nearby regions, including Orange County, Ventura County, and Western Riverside County. From community hospitals and academic medical centers to biotech labs and university research buildings, we respond quickly and build solutions that last.
