Commercial BAS (Building Automation System) Maintenance in Calabasas

What our Commercial BAS maintenance includes

We keep your Building Automation System dependable and efficient with a methodical maintenance program designed for Calabasas commercial properties and campuses. Our focus is to protect uptime, improve comfort, and deliver measurable energy savings while supporting healthy indoor air.

• Point-to-point verification of critical HVAC and ventilation I/O
• Sensor, thermostat, and actuator calibration (temperature, humidity, CO2, VOC, PM)
• Controller health checks, firmware care, license verification, and backups
• BACnet/Modbus network stability review, device discovery, and addressing clean-up
• Alarm rationalization and nuisance alarm reduction
• Graphics and naming standardization for easier operations
• Sequence of operations tuning for comfort, energy, and IAQ
• Trend setup, data analysis, and exception reporting
• VFD inspections, setpoint optimization, and economizer verification
• Demand response readiness and peak-load strategies

Every visit culminates in a maintenance report that documents findings, corrective actions, and next-step recommendations. Your facilities team receives practical takeaways and backups to maintain continuity and resilience.

Engineered for complex sites

Our family has practiced engineering for over 80 years, now in its fourth generation. That depth shows when projects get complex—multi-building campuses, mixed vintages of controls, or integrations with advanced VRF. Our factory training with Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China) gives us hands-on knowledge of how these systems behave in the field and how to tune BAS logic to get the best from them.

Whether your property uses packaged RTUs, VRF, VAV air distribution, dedicated outdoor air systems, or heat recovery, we diagnose bottlenecks quickly and restore stable, efficient operation.

Healthy air, productive spaces

Our mission is healthy indoor air for a healthy life. We maintain and trend IAQ sensors, verify ventilation and filtration strategies, and tune sequences that balance comfort, energy, and wellness. By catching drift in sensors and sequences early, we help you keep occupants comfortable and confident.

How we work

• Assess: Review current BAS architecture, sequences, alarms, trends, and pain points.
• Stabilize: Fix the fundamentals—sensors, communications, alarming, and setpoints.
• Optimize: Implement energy-saving strategies aligned with Title 24 and your KPIs.
• Document: Provide backups, revisions, and a clear punch list for ongoing improvements.

We collaborate with property managers, facility directors, and asset teams to align maintenance with operational goals, lease obligations, and occupant expectations.

Deliverables you can use

• Maintenance and calibration logs with before/after data
• Network and device maps for BACnet/Modbus devices
• Alarm matrix updates and priority/routing recommendations
• Sequence tuning notes and energy opportunity list
• Title 24 and local code compliance support

Industries we support
