Commercial Modbus Integration in Calabasas

Expert Modbus Integration for Commercial HVAC

#1 AC Guys connects your HVAC assets to a single source of truth using Modbus RTU and Modbus TCP. From rooftop units, chillers, boilers, ERVs, and VFDs to VRF and mini‑split systems, our integrations give facility teams clear visibility and actionable control. Expect consistent data, clean naming, accurate scaling, and resilient networks that reduce downtime and support better indoor air quality.

We engineer every detail: register maps, byte order and data types, polling rates, timeouts, and exception handling. Whether we are adding a Modbus master to your BMS or bridging legacy devices through gateways, our goal is dependable performance and intuitive operation.

Our Process

• Discovery and survey: inventory equipment, communication ports, and existing controls; gather submittals and register lists.

• Design and documentation: network topology, gateway specifications, point lists, addressing, and sequence of operations.

• Implementation: shielded cabling, proper terminations, addressing, grounding, and panel integration with clear labeling.

• Commissioning: device verification, live trending, alarm proofs, failover tests, and operator training.

• Turnover and support: as‑builts, point mapping, O&M documentation, and responsive post‑project support.

Technical Capabilities

We integrate Modbus RTU over RS‑485 and Modbus TCP over IP networks, implement multi‑segment topologies with proper termination, and apply best practices for noise immunity and addressing. Our team configures gateways for Modbus‑to‑BACnet when required, normalizes units and scaling, and implements alarm thresholds, schedules, and overrides with clear operator graphics and trends.

For VRF and mini‑split fleets from Fujitsu, Mitsubishi Electric, Midea, Gree, and Haier, we connect indoor and outdoor units through manufacturer interface modules where applicable, exposing temperature, fan, mode, setpoints, error codes, and energy data for your building management system.

Healthy Air by Design

Healthy indoor air is our mission. Through Modbus integration, we tie IAQ sensors for CO₂, VOC, humidity, and particulate matter to demand‑controlled ventilation, optimize outdoor air economizers, and coordinate filtration and ERV heat recovery. The outcome is better comfort, reduced energy use, and verifiable IAQ metrics for stakeholders.
