Commercial Modbus Integration in Glendale, CA

When your Glendale facility depends on accurate HVAC data and dependable automation, Modbus is often the backbone that ties everything together. #1 AC Guys integrates Modbus RTU over RS‑485 and Modbus TCP/IP into your existing BMS/BAS, SCADA, or energy platforms so you can monitor, control, and optimize equipment with confidence. As a 4th‑generation family business with 80+ years in engineering, we approach controls with an engineer’s rigor and a builder’s practicality—delivering systems that are stable, well‑documented, and easy to expand.

What we integrate

• Rooftop units (RTUs), AHUs, MAUs, heat pumps, fan coils
• VRF/VRV systems from Fujitsu, Mitsubishi Electric, Midea, Gree, and Haier via supported gateways
• Chillers, boilers, cooling towers, heat exchangers
• VFDs, dampers, valves, pumps, and actuators
• Energy and power meters, gas/water submeters, IAQ sensors (CO2, PM, VOC), and economizers
• Bridging Modbus to BACnet/IP or BACnet MS/TP for enterprise BMS

Our engineers select and configure gateways, map registers with clear naming conventions, set alarm thresholds and priorities, and build trend logs that make sense to operators and analytics tools. The result is clean, validated data and reliable control loops that enhance comfort, air quality, and energy efficiency.

Factory-trained on key systems

Our team has trained at manufacturer facilities of Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China). That background helps us integrate VRF/VRV and split systems using approved gateways, expose the right read/write points (modes, setpoints, fan speeds, thermistors, error codes), and ensure safe command limits that protect equipment life.

Engineering-first workflow

• Site and network assessment: inventory devices, confirm RS‑485 topology, IP scheme, grounding, and terminations
• Design and submittals: point lists, sequence of operations, gateway selections, addressing plans, and cybersecurity posture
• Programming and staging: lab test registers, simulate faults, verify scaling, units, and control authority
• Commissioning: live I/O checks, trending, alarm validation, rollback plan, and handover testing
• Training and documentation: O&M manuals, point maps, network diagrams, and operator training
• Support: remote monitoring, change management, and scheduled tune‑ups

We design for serviceability. Every integration ships with a readable point list, register map, and wiring/network diagram, plus a change log so your team always knows what changed, when, and why.

Healthier air, better outcomes

Healthy air is our mission. By surfacing the right Modbus points and logic—outdoor air flow, CO2‑based ventilation, filter pressure drop, coil temps, humidity control—you can maintain cleaner air and meet ventilation targets while minimizing energy waste. Trend logs support data‑driven maintenance and help demonstrate conformance with internal policies and standards like ASHRAE guidelines and California Title 24 requirements.

Glendale focus

We support offices, medical suites, retail, hospitality, multi‑family common areas, schools, and light industrial sites across Glendale. Our team coordinates work around business hours to minimize downtime, and we can assist with documentation for utility incentive applications (including Glendale Water & Power programs where applicable). If you operate across LA County, we also cover nearby Orange County, Ventura County, and Western Riverside County.

Cybersecurity and reliability

We adhere to network segmentation best practices, role‑based access, and documented addressing so your BAS remains manageable and secure. Where appropriate, we employ protocol isolation, read‑only mirrors for analytics, and backups for gateways and controllers. Redundant power, surge protection, and proper grounding ensure robust RS‑485 performance and long equipment life.
