Commercial BACnet Integration for Carrier Systems in Orange, CA

Why #1 AC Guys for Carrier BACnet in Orange

We are a 4th‑generation family of engineers with 80+ years in engineering, focused on commercial HVAC controls that improve comfort, efficiency, and indoor air quality. Our team is trained at the factories of Fujitsu (Japan), Mitsubishi Elektrik (Thailand), Midea (China), Gree (China), and Hier (China). We apply that deep, hands‑on rigor to integrate Carrier systems into reliable BACnet ecosystems—without vendor lock‑in, finger‑pointing, or downtime surprises.

Headquartered in Greater Los Angeles, we serve Orange and all of Orange County with same‑week site assessments and after‑hours cutovers. We also cover Los Angeles County, Ventura County, and Western Riverside County.

What We Integrate

• Carrier rooftop units (RTUs), chillers, and air handlers (AHUs)
• VAV, FPB, and fan coil units with BACnet controllers
• Existing and new BMS platforms via BACnet MS/TP or BACnet/IP
• Plant equipment: pumps, towers, and heat exchangers
• Room‑level devices: thermostats, IAQ/CO2 sensors, and airflow stations

Our scope runs from device discovery and instance numbering to sequences of operation, trend logs, alarms, schedules, and graphics that make daily operations intuitive.

Deep BACnet Expertise

Whether your project calls for BACnet MS/TP on RS‑485 trunks or BACnet/IP with BBMDs and foreign devices across VLANs, we engineer the topology for stability and speed. We standardize device instances, object naming, COV subscriptions, and priority arrays, and we validate every point against the sequence of operations.

• MS/TP tuning: token timing, max masters, baud rates, and biasing for noisy trunks
• IP routing: BBMD config, broadcast management, and subnet planning
• Cyber‑hygiene: credential policies, segmented networks, and change tracking
• Standards‑based graphics: readable naming, units, and color conventions

Carrier‑Focused Integration Deliverables

We routinely integrate Carrier RTUs, chillers, and AHUs into existing or new BMS platforms. While we are not affiliated with Carrier, we understand how to expose the right points to BACnet and make them functional for operators.

• Point lists: writable setpoints, command priorities, and alarm thresholds
• Trending: energy, runtime, supply/return temps, static pressure, and CO2
• Alarming: actionable limits and deadbands to reduce nuisance noise
• Schedules: holiday tables and demand‑response strategies
• Graphics: one‑line plant overviews and floor‑by‑floor equipment views

Healthy Air, Healthy Operations

Healthy air is our mission. We design integrations that support indoor air quality, including MERV‑13+ filtration strategies, UV‑C options, outdoor‑air verification, pressure‑based ventilation control, and CO2‑driven demand control ventilation. Your Carrier equipment becomes a data‑rich asset that supports both wellness and energy efficiency.

Process You Can Trust

• Assessment: on‑site survey in Orange to document equipment, networks, and goals
• Design: BACnet architecture, point maps, and sequence alignment
• Submittals: drawings, naming conventions, and commissioning plan
• Deployment: staged or after‑hours cutover to protect operations
• Commissioning: point‑to‑point testing, graphics, alarm tuning, and training
• Support: remote monitoring options and rapid response service

Title 24 and Local Compliance

We align controls with California Title 24 Part 6 and CALGreen objectives, helping owners meet code requirements and utility incentive criteria. From fault detection and diagnostics points to trend durations and ventilation verification, we configure BACnet objects that support compliance and documentation.
