Rialto Commercial Hospital & Lab Ventilation

Healthcare and laboratory environments demand more than comfort—they require engineered ventilation that protects life, supports clinical outcomes, and preserves research integrity. At #1 AC Guys, we translate 80+ years of engineering experience into hospital- and lab-ready air systems for Rialto’s most demanding facilities.

Why #1 AC Guys

• 4th‑generation family engineers specializing in complex commercial HVAC
• Proven delivery on hospital, clinical, and laboratory projects of all sizes
• Design-build, retrofit, commissioning, and validation under one roof
• ASHRAE 170, FGI Guidelines, HCAI (OSHPD), Title 24, CDC, and Joint Commission alignment
• Data‑driven controls, BAS integration (BACnet/Modbus), and IAQ analytics

Our team is factory‑educated by Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China), bringing deep technical rigor to every system we touch.

Engineering ventilation for hospitals and labs

We design and validate airflow strategies that maintain correct pressure cascades, thermal comfort, and contaminant control:

• Negative and positive pressure rooms (airborne infection isolation, protective environment)
• Operating rooms and procedure suites with laminar flow strategies
• Cleanrooms (ISO classes), BSL labs, and vivaria with precise ACH and filtration
• Fume hood exhaust with VAV tracking and spill response modes
• Dedicated Outdoor Air Systems (DOAS) with energy recovery (ERV/HRV)
• High‑efficiency HEPA/ULPA filtration, MERV 13+, and optional UV‑C
• Redundant fans and N+1 strategies for mission‑critical uptime

Every system is balanced and verified through TAB, sensor calibration, and performance documentation so you can pass inspections and audits with confidence.

Lennox-focused solutions

We service and optimize Lennox air handlers, rooftop units (RTUs), split systems, and DOAS configurations for healthcare and laboratory applications—integrating advanced filtration, pressure control, and energy recovery where appropriate. Our engineers tune controls, sequence ventilation modes, and integrate Lennox equipment into your BAS to improve stability, efficiency, and compliance. Lennox is a trademark of its respective owner; we provide independent service and integration expertise.

Codes, standards, and compliance

• ASHRAE 170 and FGI Guidelines for healthcare ventilation
• HCAI (OSHPD) procedures for California healthcare construction
• Title 24 energy codes aligned with clinical requirements
• CDC, NIH/BSL considerations, and Cal/OSHA safety practices

Our documentation packages include design intent, submittals, TAB reports, pressure logs, filtration specs, and control sequences to streamline approvals and accreditation.

Services we provide

• Consulting, load calculations, and ventilation modeling
• Design-build and plan/spec execution
• Retrofits, upgrades, and expansion of existing systems
• TAB, commissioning, re‑commissioning, and validation
• HEPA/ULPA filters, UV‑C, and IAQ monitoring installations
• Controls programming, BAS integration, alarm strategies
• Predictive and preventive maintenance, filter programs
• 24/7 emergency response and critical repairs

Technology that protects and performs

We integrate DOAS with ERV wheels or plates, high‑turndown fans, variable speed drives, and VAV terminals with sash/fume hood tracking. Continuous IAQ monitoring (PM2.5, TVOC, CO2, differential pressure) feeds alarms and trend analyses so you can proactively manage risk and energy. Our sequences maintain pressure relationships during door events, filter loading, and utility fluctuations.

Where retrofits are required, we prioritize low‑downtime phasing, temporary ventilation, and pre‑fabricated skids to keep care and research moving without sacrificing safety.

Serving Rialto and the greater LA region

We support facilities in Rialto and across the greater Los Angeles area, including Los Angeles County and nearby regions: Orange County, Ventura County, and Western Riverside County. Whether you operate a hospital campus, ambulatory surgery center, diagnostic lab, university research facility, or biotech cleanroom, our team mobilizes quickly and scales to your timeline.

Our mission: healthy air for healthy lives

As a family business in its 4th generation, we believe healthy indoor air is essential to patient outcomes, staff wellbeing, and research quality. We build systems that are resilient, testable, maintainable, and energy‑smart—so you can focus on care and discovery.
