Commercial Hospital & Lab Ventilation in Rialto — Daikin Systems

What we deliver for hospitals and laboratories in Rialto

Our engineers specialize in high-stakes environments where air quality and reliability are mission-critical. We plan and implement complete ventilation ecosystems centered on Daikin equipment to achieve stable pressure, precise air changes, temperature and humidity control, and energy efficiency.

• Daikin VRV/VRF systems integrated with dedicated outdoor air systems (DOAS) for high-density clinical and lab spaces
• Air handling units with HEPA/ULPA filtration, fan arrays (N+1), humidification/dehumidification, and corrosion-resistant coils
• Energy recovery ventilators (ERV/HRV) to reduce operating costs while maintaining compliance
• Isolation rooms (negative/positive), anterooms, and pressure monitors with continuous logging
• Operating room ventilation, laminar flow strategies, and temperature/humidity stability
• Compounding pharmacy ventilation aligned with USP 797/800 and AHJ mandates
• Lab exhaust and make-up air integration for fume hoods and biosafety cabinets
• Controls and BMS integration (BACnet/Modbus), alarm notifications, and remote monitoring
• Sound and vibration mitigation, duct leakage control, and clean construction practices

Why #1 AC Guys

#1 AC Guys is a fourth-generation family business with 80+ years in engineering. We are known for tackling complex scopes other firms avoid, delivering rigor from design through commissioning.

• Deep healthcare and lab focus: infection control, redundancy, and uptime by design
• Factory-trained engineers: Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China)
• Daikin-centric expertise: AHUs, VRV/VRF, packaged rooftop units, and controls
• Commissioning and validation: TAB, room pressure mapping, sensor calibration, and turnover documentation
• Lifecycle value: energy modeling, ERV strategies, and right-sized filtration plans
• 24/7 response and proactive maintenance programs to sustain compliance

Codes and standards we align with

We design and implement systems to align with widely adopted standards and local authority requirements, including ASHRAE 170, ASHRAE 62.1, California Title 24, HCAI (formerly OSHPD) guidelines, CDC recommendations for labs and isolation spaces, USP 797/800 for compounding pharmacies, NFPA 99 for healthcare facilities, and NFPA 45/ANSI Z9.5 for laboratories, as applicable by the AHJ.

Our documentation package typically covers basis-of-design, equipment schedules, control sequences, balance reports, pressure logs, and O&M manuals—accelerating approvals and audits.

Our process

• Assessment: site walk, data logging, pressure relationship verification, and risk review
• Engineering: load calculations, airflow modeling, filtration strategy, and controls architecture
• Submittals & permitting: coordination with the AHJ and healthcare compliance teams
• Build & integration: clean install, infection-control barriers, and BMS tie-in
• Commissioning: TAB, functional performance testing, alarms, and trending
• Training & maintenance: staff training, PM schedules, and performance dashboards

Daikin systems we service and integrate

We support Daikin VRV/VRF networks, air handlers, rooftop units, dedicated outdoor air systems, and energy recovery ventilators for healthcare and lab environments. Our team designs sequences for pressurization control, setback modes, economizer logic, and adaptive humidity management—delivering stable conditions with smart energy use.

Preventive maintenance for compliance and uptime

Planned maintenance preserves accreditation readiness and lowers risk. Our PM programs include:

• Filter and HEPA change-outs with lot tracking
• Coil cleaning, drain sanitation, and UV-C system upkeep
• Sensor calibration (temperature, humidity, pressure) and alarm verification
• Fan array checks, belt/drive inspections, and vibration analysis
• Room pressure audits and airflow rebalancing after changes

You receive detailed service records to support audits and internal quality systems.

Healthy air is our mission

Our mission is simple: healthy air for healthy life. In clinical and research settings, that mission translates into cleaner rooms, safer pressure cascades, and dependable operation—day and night.
