Commercial BACnet Integration in Fullerton, CA

Why BACnet Matters for Fullerton Facilities

Open BACnet integration gives building owners in Fullerton the flexibility to connect diverse HVAC assets under one interoperable platform. From VRF and rooftop units to boilers, VAV boxes, economizers, and IAQ sensors, a unified BACnet network streamlines control, trends performance, and exposes real energy savings opportunities. Our mission is healthy air for healthy life—so every sequence we design balances indoor air quality, comfort, and efficiency across seasons.

As a 4th‑generation family of engineers with 80+ years in engineering, #1 AC Guys is built for large and complex projects. We translate real‑world mechanical behavior into reliable BACnet logic that operators can trust day after day.

What We Integrate

We connect new and legacy equipment to a common BACnet backbone to improve visibility and control.

• VRF and ductless systems via manufacturer gateways (Fujitsu, Mitsubishi Elektrik, Midea, Gree, Hier) with approved data points and sequences.
• Rooftop units (RTUs), split systems, heat pumps, boilers, and chillers with standardized control objects for modes, safeties, and alarms.
• Airside devices: VAV/VVT, economizers, fans, air handlers, and ERVs with demand‑controlled ventilation.
• Indoor air quality: CO₂, PM, TVOC, humidity, and temperature sensors tied to ventilation strategies.
• Energy meters and demand management: trend logs, schedules, and reset strategies that support comfort and lower consumption.
• Bridging of smart thermostats and stand‑alone controllers into BACnet networks where appropriate.

We maintain consistent naming conventions and units, so operators and analytics tools can quickly understand point data across the portfolio.

Our Process

• Assessment & Planning: Site walk, network review, equipment inventory, and objectives alignment for comfort, IAQ, and energy.
• Design & Sequences: BACnet architecture, controller selection, gateways, and sequences of operation aligned with manufacturer guidance.
• Programming & Panels: Control logic, graphics, and panel layout with service access and future expansion in mind.
• Integration & Commissioning: Point‑to‑point verification, functional testing, alarm strategy, and trend setups for verification and tuning.
• Documentation & Training: As‑builts, network diagrams, point lists, sequences, and operator training for confident day‑to‑day use.
• Support & Optimization: Seasonal tune‑ups, updates, and enhancements as needs evolve.

Throughout the project we follow pragmatic cybersecurity practices (role‑based access, segmented networks, and backups) appropriate for building control systems.

Deliverables You Can Count On

• Clear BACnet device IDs, naming standards, and point lists.
• Graphics, schedules, alarms, and trend logs configured for fast diagnostics.
• Functional test sheets and commissioning reports.
• As‑built drawings and network topology diagrams for future serviceability.
• Sequences of operation focused on healthy air, comfort stability, and energy performance.

We also help align your controls approach with California energy objectives and good engineering practice, supporting Title 24 compliance efforts in collaboration with your project team.

Built for Complex Commercial Projects

We specialize in commercial and mixed‑use buildings where multiple systems must act as one: campuses, healthcare clinics, hospitality, retail, education, multifamily common areas, and light industrial. Our factory training at Fujitsu (Japan), Mitsubishi Elektrik (Thailand), Midea (China), Gree (China), and Hier (China) helps us integrate VRF equipment with the right gateways and sequences while preserving intended protections and manufacturer guidance.

Whether you are migrating from a proprietary platform, expanding an existing network, or standardizing multiple sites, we deliver a roadmap that scales.

Service Area & Response

We are based in Southern California and serve Fullerton and the surrounding region: Orange County, Los Angeles County, Ventura County, and Western Riverside County. We coordinate closely with owners, GCs, MEP engineers, and facility teams to minimize disruption during cutover and commissioning.

Fullerton’s climate and code environment reward smart ventilation and staged control. We design sequences that respond to local conditions—optimizing outside air, reset strategies, and occupancy schedules to keep spaces comfortable and air quality high.

Getting Started

Every successful BACnet integration begins with clear goals and a solid plan. We start by listening, then provide a practical scope, timeline, and integration diagram so you know exactly how we will connect each device and validate performance.

• Discovery call and data gathering.
• On‑site survey and equipment review.
• Proposed architecture, device list, and sequence outline.
• Implementation, commissioning, and training.
• Post‑occupancy tuning and seasonal optimization.
