Commercial Laboratory Environmental Controls in Rialto

What We Engineer and Deliver

Your laboratory’s science depends on stable, verifiable environmental conditions. We design, install, commission, and maintain complete HVAC control ecosystems for commercial labs in Rialto and the Inland Empire, including Western Riverside County. Our focus: airtight temperature, humidity, airflow, and pressure control that supports your SOPs, staff safety, and quality systems.

• Cleanrooms (ISO 14644) with validated air changes, filtration, and envelope integrity
• Compounding pharmacies supporting USP 797/800 standards
• BSL labs, vivaria, and specialized R&D suites
• VAV/VVT zoning, fume hood containment, and exhaust dilution
• Positive/negative pressure rooms with cascading differentials
• Temperature/humidity control rooms, stability chambers, and environmental rooms
• Redundant and fail-safe strategies for critical spaces
• Central plant optimization and energy recovery for lifecycle savings

Controls and Integration

We implement open, interoperable controls that fit your IT and facility standards. Our BAS solutions (BACnet, Modbus, and secure IP) enable trending, alarming, scheduling, and remote support. We integrate with lab equipment interlocks, differential pressure monitors, and data logging to support audits and CAPA workflows.

• Room pressure monitors with visual and audible alarms
• HEPA/ULPA filtration with differential pressure tracking
• Fume hood face velocity monitoring and sash position sensing
• VAV terminal control for airflow stability and energy efficiency
• Sequence of operations tailored to your protocols
• Secure remote access for 24/7 support and diagnostics

AC PRO-Sourced Speed and Reliability

Through AC PRO’s Southern California distribution network, we source commercial-grade air handlers, controls, filtration, and replacement parts quickly—helping your project stay on schedule and your facility online. Rapid procurement reduces downtime and accelerates commissioning.

Factory-Trained Engineering Talent

Our engineers have completed factory training with Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China). Combined with our fourth-generation engineering heritage (80+ years of cumulative experience), we bring disciplined design, precise installation, and documented verification to every lab environment.

Commissioning, Validation Support, and Documentation

We plan for audit-ready results from day one. Expect a detailed sequence of operations, setpoint maps, trend logs, and as-builts. We provide commissioning and validation support (IQ/OQ/PQ assistance) and help align with ISO 14644, USP 797/800, ASHRAE 170/62.1, and California Title 24 requirements applicable to HVAC performance.

• Pre-functional and functional testing with calibrated instruments
• Airflow balancing and pressurization verification
• Temperature/humidity stability testing and trending
• Alarm setpoint verification and failover exercises
• Turnover packages to support inspections and SOP integration

Preventive Maintenance and 24/7 Response

Critical environments demand zero surprises. Our preventive programs include filter strategies (HEPA/ULPA), coil hygiene, sensor calibration, damper and valve verification, and seasonal re-commissioning. We offer 24/7 emergency response with stocked AC PRO-sourced parts to minimize MTTR and protect your research and product integrity.

Project Delivery Built for Complex Labs

From retrofit to new construction, we coordinate with architects, GC/CM teams, and validation consultants to minimize lab downtime and contamination risk.

• Design-build or design-assist delivery
• Phased cutovers and temporary conditioning plans
• Containment protocols to protect active spaces
• Risk and impact assessments with mitigation steps

Health-Focused Mission

Our mission is healthy air for a healthy life. For laboratories, that means dependable controls that protect people, processes, and patient outcomes—without sacrificing energy performance. We leverage energy recovery, variable-speed drives, and advanced sequences to curb operating costs while preserving strict environmental targets.

Service Area

We are a Los Angeles-based, fourth-generation family business proudly serving Rialto and nearby Inland Empire communities, including Western Riverside County, as well as Los Angeles, Orange, and Ventura counties.
