Commercial BACnet Integration — Ontario, CA

When your building depends on clarity, uptime, and energy accountability, BACnet is the open protocol that keeps vendors honest and data accessible. #1 AC Guys engineers deploy BACnet gateways, controllers, and network architecture that bring AC PRO–supplied equipment and multi‑brand HVAC assets into one high‑performing, future‑ready platform.

What we integrate

• AC PRO–supplied rooftop units, split systems, heat pumps, economizers
• VRF/mini‑split systems from Fujitsu and Mitsubishi Electric via native BACnet or gateway
• Air handling units, VAV/FPB, DOAS and ventilation with CO2‑based demand control
• Boilers, chillers, pumps, heat exchangers, cooling towers, and associated safeties
• Room and duct sensors (temperature, humidity, CO2), fan arrays, and filtration status

We connect via BACnet/IP or BACnet MS/TP, tune network speeds, set device instance ranges, implement BBMDs for routing, and map points with naming that aligns to your sequence of operations. You get organized folders, alarm priorities, trend intervals, and graphics that actually match the field devices.

Why #1 AC Guys for BACnet in Ontario

• 80+ years of engineering and 4th‑generation family expertise focused on HVAC controls
• Factory‑trained at Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China)
• Specialists in large, complex commercial and multi‑site integrations
• Documentation first: drawings, point lists, sequences, and as‑built packages delivered
• Title 24–aligned commissioning, trend‑based verification, and training for your staff

Healthy air is our mission. We integrate ventilation, filtration, and IAQ sensors so your BACnet system maintains proper airflow, pressurization, and CO2 levels—supporting comfort, productivity, and compliance.

Our technical approach

Every project begins with a site survey and controls audit. We capture equipment schedules, existing controls, network topology, and your operational goals. Then we engineer a BACnet design that fits: IP or MS/TP trunks, controller selection, gateway strategy, and security posture. We build a clear sequence of operations, point list, and naming standard before programming starts.

Commissioning includes loop tuning, alarm setpoints, trend plans, and functional tests against the sequence. We hand over as‑builts and train your team so the system is maintainable long after day one.

What you gain

• One interface for schedules, setpoints, alarms, and trends across AC PRO–supplied and mixed fleets
• Actionable alarms with priorities, delays, and recipients to cut nuisance noise
• Energy insights through normalized trending and runtime analytics
• Open, non‑proprietary access that prevents vendor lock‑in and eases future expansion
• Cleaner indoor air through integrated ventilation control and IAQ monitoring

Compliance and standards

Our work aligns with ASHRAE 135 (BACnet), California Title 24 controls requirements, and best practices for naming, trending, and documentation. We coordinate with your commissioning agent and facility stakeholders to prove performance with real data.

AC PRO compatibility

Whether your site uses new AC PRO–supplied equipment or a mixed legacy fleet, we can integrate via native BACnet cards or robust gateways. We replace outdated thermostats with DDC controllers where needed, preserve existing investments, and phase upgrades to minimize downtime.

• Retrofit and new‑build BACnet/IP or MS/TP networks
• Gateway strategies for VRF and packaged units
• Migrations from proprietary controls to open BACnet
• Graphics, naming, and data models that mirror field reality
