Rialto Commercial, Hospital & Lab Ventilation — Midea Factory-Trained Engineers

#1 AC Guys is the trusted partner for Rialto healthcare and research facilities that demand verifiable performance from their ventilation systems. As a fourth‑generation family of engineers with 80+ years of combined engineering experience, we specialize in complex commercial, hospital, and laboratory projects where airflow, pressure control, and indoor air quality are mission‑critical.

Healthcare-Grade Ventilation, Designed for Compliance

Our designs align with key industry standards and guidance, including ASHRAE 170 for healthcare ventilation, California Title 24 energy requirements, California Mechanical Code, and current CDC recommendations for infection control. We engineer systems to achieve correct air changes per hour (ACH), directional airflow, and pressure differentials across isolation suites, operating areas, procedure rooms, pharmacies, and support spaces.

• Negative and positive pressure room strategies with monitored pressure cascades
• HEPA and high-MERV filtration upgrades for particulate and pathogen control
• Temperature and humidity stability to support patient comfort and lab protocols
• Efficient outdoor air treatment via DOAS with ERV/energy recovery
• Quiet, low-vibration designs that protect sensitive equipment and workflows

Midea Solutions for Hospitals and Labs

Factory-trained by Midea (China), our team integrates Midea VRF with dedicated outdoor air systems (DOAS), energy recovery ventilators, and smart controls to deliver consistent ventilation, temperature, and humidity while optimizing energy use. Midea VRF enables zoning, heat recovery, and redundancy; Midea DOAS conditions and dehumidifies outside air to precise setpoints before it enters your critical spaces.

• VRF + DOAS for pressurization-sensitive zones
• Advanced controls and BMS/BAS integration
• Redundant fan arrays and service-friendly layouts
• Retrofit pathways that minimize downtime and disruption

In addition to Midea factory training, our engineers have trained at the factories of Fujitsu (Japan), Mitsubishi Electric (Thailand), Gree (China), and Haier (China). This manufacturer-level knowledge helps us optimize selection, layout, and commissioning for demanding healthcare and research applications.

End-to-End Services

• Consultation and load/ventilation calculations
• Design-build engineering and permitting support
• Equipment selection, procurement, and logistics
• Installation, start-up, and commissioning
• Testing, adjusting, and balancing (TAB) with documentation
• Controls programming, trending, and alarms
• Ongoing maintenance, IAQ audits, and performance tuning

We also provide emergency response and rapid remediation plans to restore safe operations after failures, contamination events, or environmental excursions.

Laboratory Ventilation & Safety

For research and clinical labs, we design exhaust and make-up air systems that support fume hoods, biosafety cabinets, clean benches, and process exhaust while maintaining pressure discipline. Where required, we coordinate with your EH&S team for airflow setpoints, sash performance criteria, and alarm thresholds.

• Fume hood exhaust with diversity and diversity-factor modeling
• Room-level airflow tracking and sash management support
• Make-up air conditioning for thermal comfort and stability
• Energy recovery strategies that protect containment

Proven Process for Reliable Outcomes

Every project follows a documented pathway: discovery and risk review, basis-of-design with compliance mapping, detailed submittals, installation by specialized crews, instrumented start-up, and TAB. We verify pressure, ACH, filtration, and environmental setpoints under real operating conditions, then provide owner training and digital O&M packages.
