Commercial Control Systems in Long Beach

What We Deliver

Our Commercial Control Systems service equips Long Beach businesses with smart, scalable HVAC automation. We design and program control sequences that stabilize temperatures, improve indoor air quality, and reduce energy spend—without sacrificing tenant comfort or uptime. Every project is led by engineers who understand both the physics of air and the realities of facilities operations.

• Design/build and retrofit control systems for new and existing facilities
• BACnet and Modbus integration across multi-vendor equipment
• VRF, RTUs, VAV, economizers, make-up air, exhaust, and ventilation control
• IAQ monitoring: CO2, VOCs, PM, humidity, and temperature
• Dashboarding, scheduling, alarm strategies, and trend logging
• Retro-commissioning, optimization, and ongoing service

Systems and Protocols We Integrate

We connect your mechanical assets into a coherent, secure, and maintainable controls ecosystem. Whether we’re deploying a new BMS or enhancing an existing one, our focus is reliability, transparency, and future-ready scalability.

• BACnet/IP, BACnet MS/TP, and Modbus TCP/RTU
• VRF systems, packaged rooftop units, heat pumps, and split systems
• VAV boxes, fan coils, DOAS/make-up air, economizers, and exhaust fans
• Demand-controlled ventilation and advanced economizer logic
• Utility-responsive strategies and load shedding where applicable

AC PRO Supply Advantage

Parts availability drives project speed and uptime. We source controls, sensors, and OEM-approved components through AC PRO across Southern California to keep projects on schedule and equipment performing. This supply chain strength minimizes delays and supports long-term maintainability for Long Beach facilities.

Engineer-Led, Factory-Trained

Our fourth-generation team brings 80+ years of engineering experience to every job. We are factory-trained by five manufacturers—Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China)—so your VRF and split-system controls are configured and commissioned according to best practices. Complex sites and multi-building campuses are our specialty.

Healthy Air, Lower Energy

Our mission is healthy air for healthy living. We deploy smart ventilation that responds to occupancy and air quality, helping you meet Title 24 while maintaining comfort. Strategies may include CO2-based ventilation, optimized economizer use, filtration upgrades, humidity control, and fault detection to sustain performance over time.
