Commercial BAS (Building Automation System) Maintenance in Orange

Your BAS should be a reliable engine for comfort, air quality, and efficiency—not a source of surprises. Our commercial BAS maintenance program in the City of Orange focuses on predictable performance, clear documentation, and long‑term asset protection across AC PRO‑equipped facilities.

What we maintain and optimize

• Controls networks and protocols: BACnet/IP, BACnet MS/TP, Modbus, LonWorks
• Supervisory servers, gateways, and front ends: backups, updates, database hygiene
• Controllers and I/O: firmware, reboots, lifecycle checks, sequence verification
• HVAC assets: AC PRO RTUs and split systems, AHUs, VAVs, ERVs, economizers
• Sensors and safeties: temperature, humidity, CO2, VOC/PM, pressure, airflow
• Schedules, setpoints, resets, and demand‑limiting for energy and comfort
• Alarms and trends: normalization, deadbands, root‑cause analysis, noise reduction

We align your sequences of operation to real‑world loads, occupancy, and weather. Expect smoother startups, fewer nuisance trips, and healthier indoor air that supports productivity.

Our process blends engineering rigor with field practicality. We verify intent, measure outcomes, and close the loop with data—then document every step so you can budget, plan, and prove savings.

Our BAS maintenance deliverables

• Baseline assessment and risk ranking of your controls stack
• Seasonal inspection and cleaning of critical control components
• Point‑to‑point verification and calibration of priority sensors
• Database backups, firmware updates, and controller health checks
• Trend setup, alarm rationalization, and fault detection rules
• Economizer and ventilation optimization for IAQ and energy
• Setpoint, schedule, and reset strategy tuning with change logs
• Energy and comfort KPIs with before/after snapshots
• Staff coaching and turnover notes to reduce operator dependency

We also prepare sites for seasonal transitions—heating to cooling and vice versa—to minimize surprises at first demand. This reduces overtime calls and extends the life of your AC PRO and related HVAC assets.
When issues surface, our engineers trace root causes, not symptoms, so fixes stick.

AC PRO and your BAS

Whether your facility uses AC PRO rooftop units, split systems, or accessories, we keep the BAS talking clearly to each device and subsystem. That includes verifying control points, economizer logic, fan safeties, and ventilation targets so your AC PRO equipment operates within design intent. We coordinate with your existing front end or help standardize your graphics, naming, and trends for a cleaner operator experience.

Industries we serve

• Office and mixed‑use buildings
• Retail and shopping centers
• Healthcare and clinics
• Education and campuses
• Light industrial and R&D
• Hospitality and entertainment

In each environment, we prioritize occupant health and uptime while driving measurable reductions in kWh and maintenance spend.

Compliance, IAQ, and energy outcomes

Our maintenance supports California Title 24, including ventilation verification, optimal start/stop, and demand‑controlled ventilation where applicable. We calibrate CO2 and other IAQ sensors and adjust outside air strategies to balance health and efficiency. The result: cleaner air, steadier comfort, and predictable bills.

Service area

We proudly serve the City of Orange and greater Orange County, with rapid dispatch across Los Angeles County, Ventura County, and Western Riverside County for regional portfolios. One team, one standard—consistent results across every site.
