Commercial Building Management System (BMS) in Fullerton

In Fullerton and throughout Orange County, mission‑critical buildings demand reliable control, clean indoor air, and verifiable energy performance. Our commercial BMS solutions bring your mechanical and electrical systems together under one secure, intuitive interface—so your team gets real‑time insight, faster decisions, and fewer surprises.

What we deliver

• End‑to‑end BMS: design, integration, programming, commissioning, and lifecycle service
• Open protocols: BACnet and Modbus for interoperable, future‑ready systems
• HVAC integration: VRF/ductless, RTUs, chillers, boilers, VAV/VVT, VFDs, and ventilation
• IAQ and health: CO2, PM, VOC, humidity, filtration, demand‑controlled ventilation
• Dashboards and analytics: trending, alarms, FDD logic, and energy KPIs
• Retrofits: migrate legacy and stranded assets without disrupting operations
• Cyber‑aware architecture: network segmentation and role‑based access

Our mission is healthy air for a healthy life. We align sequences of operation with IAQ best practices to improve comfort and productivity while keeping energy in check.

Open integration without lock‑in

We prioritize open standards so your building stays flexible. Whether you need BACnet MSTP/IP or Modbus RTU/TCP, we integrate field devices, meters, and controllers into a single pane of glass. Result: fewer vendor silos, simpler upgrades, and a lower total cost of ownership.

Equipment expertise matters. Our team holds factory training from manufacturer facilities with Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China). That training informs how we commission VRF, economizers, heat recovery, and ventilation to protect equipment life and occupant health.

Healthier indoor air, better workplaces

Healthy air is not optional. We engineer BMS strategies that monitor and control CO2, humidity, filtration status, and outdoor air, enabling demand‑controlled ventilation and air changes based on occupancy and air quality signals. You get cleaner air, steadier temperatures, and less wasted energy.

• Dynamic outdoor air control to balance IAQ and savings
• Filtration monitoring to maintain performance
• Smart scheduling for after‑hours and partial occupancy
• Alarm strategies that surface what matters and suppress noise

Our process

• Assessment and goals: site walk, data collection, and objectives (comfort, IAQ, energy, code)
• Design and scope: sequence of operations, point lists, network topology, and phasing
• Integration and programming: standards‑based controls with clear naming and tagging
• Commissioning: functional testing, trend verification, and training for your team
• Optimization: analytics, alarm tuning, and seasonal re‑commissioning

We document every step—so you own your data, your drawings, and your outcomes.

Frequently asked questions

What systems can you integrate?
HVAC (VRF, RTUs, chillers, boilers), ventilation and IAQ sensors, meters, lighting interfaces, and more via BACnet or Modbus.

Can you retrofit our existing controls?
Yes. We phase replacements, reuse viable components, and migrate data to minimize downtime and protect your investment.

How fast can we start?
Most projects begin with a same‑day or next‑day assessment in Fullerton, followed by a detailed scope, schedule, and budget.

Do you provide training and support?
Absolutely. We train your staff on day‑one and offer ongoing optimization and service plans tailored to your facility.
