Commercial Building Management System (BMS) – Los Angeles

Your building deserves a BMS that is engineered for reliability, clarity, and long‑term value. #1 AC Guys designs and integrates commercial Building Management Systems that connect HVAC equipment, ventilation, IAQ sensors, and energy analytics—so you can control costs, enhance occupant comfort, and document performance with confidence.

What we deliver

• Full BMS/BAS design and integration for commercial properties
• HVAC controls for VRF/VRV (Fujitsu, Mitsubishi Electric) and conventional systems
• Chiller/boiler plant, air handler, VAV, economizer, and ventilation control strategies
• BACnet (IP/MSTP) and Modbus integration, gateways, and device commissioning
• Energy dashboards, trend logging, alarms, and remote access
• IAQ monitoring (CO2, PM2.5, VOCs, humidity, temperature) and demand‑control ventilation
• Sequence of operations development, tuning, and optimization
• Integration around AC PRO–specified equipment, parts, and accessories
• Documentation, as‑builts, and operator training

From single buildings to multi‑facility portfolios, our systems help operations teams detect issues earlier, respond faster, and run equipment in line with design intent and local codes.

Why #1 AC Guys

• 80+ years of engineering experience from a fourth‑generation family of engineers
• Factory‑trained at Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China)
• Specialists in large and complex commercial projects with phased deployments
• Engineered, code‑aware sequences that support California Title 24 requirements
• Proactive commissioning, functional testing, and performance validation
• Local access to AC PRO–specified equipment and parts for timely upgrades and service
• Clear documentation, training, and knowledge transfer for your facilities team

Our mission is healthy air for healthy lives. We bake indoor air quality into the controls strategy—balancing ventilation, filtration, and energy use—so occupants feel the difference while owners see measurable operational clarity.

How our BMS process works

• Discovery and goals: We assess your facility, loads, and operational priorities.
• Design and controls submittal: We craft a tailored sequence of operations and integration plan.
• Installation and integration: Controllers, sensors, networks (BACnet/Modbus) and dashboards are deployed.
• Commissioning and testing: Point‑to‑point verification, trend reviews, and functional testing.
• Training and handoff: Operators learn the system, alerts, and best‑practice maintenance.
• Lifecycle support: Ongoing optimization, expansions, and data‑driven improvements.

Need to modernize legacy controls without disrupting tenants? We can phase upgrades by floor, zone, or plant while maintaining comfort. Want portfolio‑level visibility? We design dashboards that unify multiple buildings, standardize alarms, and surface actionable KPIs.

AC PRO alignment and parts availability

We routinely integrate controls around AC PRO–specified HVAC equipment and components, leveraging local availability for faster turnarounds and reduced downtime. Whether you’re adding BACnet cards, gateways, or field devices, our team coordinates a clean, standards‑based integration and verifies performance from sensor to screen.

Healthy air and compliance

Healthy air is central to our work. We implement sensor‑driven ventilation, filtration strategies, and real‑time IAQ dashboards, helping your team monitor CO2, particulate matter, and humidity. Our engineered approach supports alignment with California energy standards and local code requirements while prioritizing occupant comfort and clarity for facility teams.
We avoid one‑size‑fits‑all controls—your sequences are tuned to your building’s loads, envelope, and use patterns.

Industries and buildings we serve

• Office towers and corporate campuses
• Retail centers and mixed‑use developments
• Healthcare clinics and ambulatory facilities
• Education and municipal buildings
• Hospitality and entertainment venues
• Industrial, light manufacturing, and warehouses
• Multifamily and condo common areas

Los Angeles business moves fast—your BMS should, too. Our engineered systems and local supply alignment help your facilities team respond quickly to alarms, streamline maintenance, and make data‑backed decisions that extend equipment life.

Service area

We serve Los Angeles County and nearby regions, including Orange County, Ventura County, and Western Riverside County. From downtown high‑rises to coastal campuses and inland industrial parks, our commercial BMS team is ready to help.
