Commercial Building Management System (BMS) Services in Long Beach

Why #1 AC Guys for Commercial BMS in Long Beach

We are a fourth-generation family business with 80+ years of engineering heritage, built on precision, safety, and measurable performance. Our mission is healthy air for healthy living, delivered through intelligent Building Management Systems that balance comfort, IAQ, and energy use. Our engineers are factory-educated by Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China). We integrate AC PRO–supplied HVAC equipment and controls into unified, open-protocol BMS architectures tailored to the realities of Long Beach coastal conditions, occupancy patterns, and energy codes.

What We Do

• BMS design/build and upgrades for commercial facilities, campuses, and mixed-use properties
• Open-protocol integration: BACnet/IP, BACnet MS/TP, Modbus RTU/TCP, LonWorks, and Niagara N4 frameworks
• VRF/VRV, DOAS, boiler/chiller plant, and airside controls with precise sequences of operation
• AC PRO–compatible controls integration, field devices, and service parts alignment
• IAQ strategies: ventilation optimization, filtration strategies, sensor placement, and continuous monitoring
• Energy optimization: scheduling, economizer logic, trim-and-respond, load shedding, and demand response
• Retro-commissioning and rebalancing to resolve comfort drift, nuisance alarms, and rogue energy use
• Dashboards, trending, and analytics that turn raw data into actionable maintenance insights
• Alarming, fault detection, and notifications for faster root-cause resolution
• Operator training, documentation, and ongoing support with planned maintenance

We support both ground-up construction and complex retrofits in occupied buildings, coordinating with owners, GCs, and facility managers to minimize downtime and disruption.

Platforms, Protocols, and Interoperability

Our team builds resilient BMS architectures around open standards so you are not locked into a single vendor’s ecosystem. We integrate BACnet and Modbus devices, tie legacy and new systems together, and unify them under Niagara N4 for consistent graphics, trends, alarming, and role-based access. This approach keeps your Long Beach facility flexible as needs evolve and as equipment is updated over time.

For variable refrigerant systems and advanced air handlers, our factory-educated engineers bring deep application knowledge of Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China). We translate manufacturer best practices into reliable sequences that protect compressors, maintain humidity control, and deliver stable comfort across diverse zones.

AC PRO Alignment

We work seamlessly with AC PRO–supplied HVAC equipment and components, aligning controls, sensors, actuators, and service parts with your BMS for maintainability and uptime. Whether your site uses AC PRO–stocked RTUs, split systems, or accessories, we integrate them into a standards-based control strategy that is easy to service and scale.

Healthy Air, Healthy Buildings

Healthy air is our mission. We design BMS sequences that actively support indoor air quality: demand-controlled ventilation tuned to occupancy, enhanced filtration strategies, appropriate economizer use, and continuous monitoring of temperature, humidity, and CO₂/TVOC where applicable. The result: cleaner air, more consistent comfort, and documented performance for compliance and ESG reporting.

Industries and Facilities We Serve in Long Beach

• Class A offices along Ocean Blvd and downtown Long Beach corridors
• Industrial and logistics near the Port of Long Beach
• Healthcare and life science facilities with tight IAQ requirements
• Education, municipal, and cultural venues
• Hospitality, retail, and mixed-use properties

If your facility is large, multi-tenant, or operationally complex, we bring the engineering depth to simplify operations and improve outcomes.

Our Process

• Discovery and goals: define comfort, IAQ, energy, and compliance targets
• Site survey and data logging: verify equipment inventory, controls topology, and performance baselines
• Design and sequences: develop open-protocol architecture, graphics, trends, and alarm strategy
• Integration and commissioning: verify points, tune loops, and validate sequences under real loads
• Training and turnover: equip your team with clear SOPs and quick-reference guides
• Support and optimization: monitor KPIs, refine schedules, and adapt to seasonal changes

Results You Can Measure

Owners and facility teams see immediate value: stabilized zone temperatures, fewer hot/cold calls, lower kWh and kW peaks, cleaner trend logs, and alarms that actually mean something. Over time, your O&M plan shifts from reactive to predictive, extending equipment life and protecting capital budgets.

Long Beach–Focused, Southern California–Wide

We proudly serve Long Beach and surrounding communities across Los Angeles County, plus Orange County, Ventura County, and Western Riverside County. From coastal corrosion considerations to utility demand response programs, we tailor your BMS to local conditions and regulations.
