Commercial Building Management System (BMS) in Fontana — AC PRO Integration

Why Fontana chooses #1 AC Guys for Commercial BMS

We are a Southern California family business serving Fontana and the Inland Empire with engineering‑first BMS solutions. Our fourth‑generation team blends 80+ years of engineering experience with modern controls to stabilize comfort, improve indoor air quality, and reduce energy spend. We excel at large and complex projects, expansions, and mission‑critical retrofits where precision and uptime matter.

We integrate AC PRO equipment and components within open‑protocol Building Management Systems, ensuring your rooftop units, VFDs, economizers, terminal units, and IAQ sensors speak the same language via BACnet or Modbus. The result: transparent data, easier service, and long‑term flexibility.

Comprehensive commercial BMS services

• Design and engineering: load analysis, control drawings, sequences of operation, point lists, and submittals for plan‑spec and design‑build projects.
• Controls integration: BACnet/IP, BACnet MS/TP, Modbus TCP/RTU, gateways for legacy devices, dashboards, trending, and alarming.
• Installation and startup: panel fabrication, sensor placement, wiring, field device calibration, functional testing, and documentation.
• Commissioning and retro‑commissioning: verify sequences under real loads, optimize setpoints, and validate KPIs for comfort and energy.
• Upgrades and retrofits: migrate pneumatics or proprietary systems to open platforms, add VFDs, DCV (CO2‑based), and advanced economizer control.
• Maintenance and monitoring: scheduled inspections, firmware updates, backups, analytics reviews, and rapid response to alarms.

Healthy air is our mission

Healthy buildings perform better. Our BMS strategies prioritize ventilation quality and filtration to support occupant health and productivity. We implement demand‑controlled ventilation using CO2 sensing, verify outside air with economizer logic, and support advanced filtration options. Where appropriate, we coordinate IAQ devices such as particulate sensors and UV‑C within the BMS to track and respond to air quality conditions.

We align control strategies with industry best practices and applicable standards to help you meet ventilation targets while avoiding energy waste. Clear trending and reports help facility teams prove performance.

Technical capabilities you can rely on

• Open protocols: BACnet and Modbus for device interoperability and future‑ready expansions.
• Energy optimization: scheduling, supply air reset, static pressure reset, VFD control, optimal start/stop, and demand limiting.
• Sequence of operations: engineered for your occupancy, process loads, climate, and utility rates.
• Dashboards and analytics: role‑based views for property managers, engineers, and executives.
• Security and resilience: segmented networks, user roles, change logs, and redundant backups.

Our engineers are factory‑trained with Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China). This manufacturer‑level perspective guides our field practices and quality benchmarks from submittal to turnover.

AC PRO integration for commercial performance

We specify, source, and support AC PRO equipment and components as part of comprehensive BMS solutions. From packaged rooftop units and air handlers to sensors and accessories, we integrate AC PRO‑supplied gear into open control architectures so your facility benefits from reliable parts availability and serviceability. No lock‑in—just a future‑proof path that keeps options open.

Industries we serve in Fontana

• Warehouses and logistics centers
• Office and medical office
• Retail and mixed‑use
• Hospitality and entertainment
• Light industrial and manufacturing

Each facility type gets a tailored sequence of operations to match occupancy patterns, ventilation needs, and process loads—ensuring comfort and efficiency across all zones.

Our process

• Discovery: site walk, equipment survey, and data review.
• Engineering: drawings, point lists, and sequences aligned to goals.
• Build and integrate: panels, devices, programming, and graphics.
• Commission: verify operation under real conditions and document results.
• Optimize: analytics‑driven improvements after the first weeks of operation.
• Support: planned maintenance, monitoring, and rapid service.

We collaborate with owners, GCs, architects, and property managers to deliver on schedule and within budget—without compromising quality.

Results you can measure

• Comfort stability: tighter control bands and fewer hot/cold calls.
• IAQ confidence: CO2, temperature, and humidity trends at a glance.
• Lower OPEX: optimized schedules, resets, and demand strategies.
• Fewer surprises: alarms, alerts, and clear fault diagnostics.

Service area and dispatch

Based in Southern California, we serve Fontana, the Inland Empire, Western Riverside County, Los Angeles County, and nearby areas including Orange and Ventura counties. Our teams coordinate closely with building staff to minimize downtime and maintain operations during cutovers and upgrades.
