Commercial Laboratory Environmental Controls in Ontario, CA

Engineering‑Driven Lab HVAC for Ontario, CA

Laboratories demand rigor. #1 AC Guys brings fourth‑generation engineering discipline to every commercial lab project in Ontario, CA—uniting precise HVAC design, intelligent controls, and lifecycle service to keep your spaces stable, safe, and compliant. We handle new construction, expansions, retrofits, and mission‑critical upgrades with minimal disruption to ongoing research and production.

What We Deliver

• Environmental stability: tight temperature and humidity bands for sensitive processes
• Airflow and pressurization: clean‑to‑less‑clean cascades to protect people and products
• Contamination control: HEPA/ULPA strategies aligned to targeted clean zones
• Fume hood performance: VAV tracking, sash management, and exhaust integration
• BAS/BMS integration: alarms, trends, and data logging for audit‑ready records
• Commissioning and balancing: proven, documented performance on day one
• Service and maintenance: preventive plans to sustain specifications over time

Systems and Capabilities

From concept to closeout, our team covers the full stack of laboratory environmental controls.

• Design and load calculations for multi‑zone labs, cleanrooms, and support spaces
• Cleanroom make‑up air units, DOAS, energy recovery, and HEPA terminal arrays
• VAV supply and exhaust, fume hood control, room pressure monitoring
• Low‑vibration, low‑noise solutions for precision instruments and vivaria
• Environmental chambers and stability rooms: conditioning and control integration
• BAS/BMS architecture: graphics, alarming tiers, remote monitoring, trend logs
• Redundancy strategies (N+1) for critical areas and equipment
• Retrofit optimization to meet California Title 24 while protecting process needs

Compliance Support

We design with recognized guidance in mind and provide documentation that supports your internal quality systems. Our work helps stakeholders address elements commonly referenced in ISO 14644 for cleanrooms, ANSI/AIHA Z9.5 for laboratory ventilation, USP‑related requirements for applicable spaces, and ASHRAE best practices, while aligning with California Title 24 energy code. We do not replace your compliance team—rather, we provide stable, measurable environmental control that supports audits and SOPs.

Controls, Monitoring, and Data

Reliable data underpins reliable labs. We integrate calibrated sensing, trending, and alarm logic so deviations are detected early and investigated quickly. Typical features include:

• Room temperature, humidity, and pressure monitoring with adjustable setpoints
• Event‑driven and time‑based alarms with email/SMS notification options
• Trend logs for investigations, CAPAs, and continuous improvement
• Fume hood sash position feedback and demand‑based ventilation
• Energy optimization sequences that maintain compliance targets

Factory‑Trained Expertise

Our engineers and technicians are factory‑trained by Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China). This manufacturer training strengthens our ability to apply advanced equipment correctly, integrate it with building automation, and commission it to specification on complex lab projects.

Our Process

• Assessment and goals: site walk, risk review, and criticality mapping
• Engineering and submittals: calculations, sequences, and coordination with your team
• Installation and integration: clean execution with safety and schedule discipline
• Startup, commissioning, and balancing: verification, tuning, and documentation
• Training and turnover: operator onboarding and clear SOP‑friendly records
• Service lifecycle: preventive maintenance and continuous optimization
