Commercial BAS (Building Automation System) Maintenance in Los Angeles

What Our Commercial BAS Maintenance Includes

Our program focuses on reliability, healthy indoor air, and measurable performance. We combine field inspection with data‑driven analysis to keep your Building Automation System operating the way it was designed.

• Controls and sequence verification: review modes, setpoints, resets, and safeties
• Sensor calibration: temperature, humidity, pressure, CO2 and IAQ points validated and adjusted
• Network health checks: BACnet/Modbus device status, communication errors, time sync, trends
• Firmware and software updates per approved change control
• Alarms review and rationalization: priority, nuisance reduction, response guidance
• VFDs, actuators, and economizers: command/feedback alignment and damper motion checks
• Schedules and holidays: occupancy alignment and off‑hour optimization
• Energy optimization: trim and respond strategies, supply air reset, economizer enable points
• Trend setup: key point logging for diagnostics and continuous improvement
• Documentation: findings, adjustments, and recommendations with a clear action list

Healthy Air, Smarter Energy

Comfort starts with clean, well‑controlled air. We verify ventilation rates, CO2 control, filtration strategies, and economizer operation so your BAS supports healthier indoor environments. At the same time, we target avoidable energy waste by tightening schedules, correcting setpoint drift, and enabling smart sequences that adapt to weather and occupancy.

Expect steadier temperatures, quieter operation, fewer hot/cold calls, and actionable insights from trends—not just a checkbox inspection. Our approach helps facilities teams anticipate issues before they become breakdowns.

Industries and Facilities We Serve

Service Area

We serve Los Angeles County and nearby regions across Southern California, including Orange County, Ventura County, and Western Riverside County. If your property portfolio spans multiple counties, we coordinate maintenance to minimize disruption and align standards across sites.

Maintenance Plans and Process

We tailor frequency and scope to the complexity of your building and mission‑critical needs.

• Assessment and benchmarking: review existing graphics, trends, and sequences
• Seasonal tune‑ups: cooling/heating changeover checks and economizer readiness
• Point‑to‑point verification: critical points tested and documented
• Alarm and trend optimization: reduce noise, increase signal, and track KPIs
• Operator coaching: quick tips and playbooks for faster on‑site resolution
• Improvement roadmap: prioritize fixes, retrofits, and control updates

We can also integrate maintenance with capital planning so recommended upgrades are budgeted and sequenced sensibly.
Need after‑visit support? We offer follow‑up check‑ins to review data and tune settings as conditions change.

Systems, Protocols, and Integration

We work across open protocols such as BACnet, Modbus, and more—aligning air‑side and water‑side control strategies with your HVAC equipment. Our team is factory‑trained by Fujitsu (Japan), Mitsubishi Elektrik (Thailand), Midea (China), Gree (China), and Hier (China), and we regularly integrate BAS with VRF/mini‑split networks, air handlers, VAV, economizers, and IAQ sensors to deliver stable, efficient operation.

Documentation and Compliance Support

Each visit includes a concise report summarizing findings, adjustments, and next steps. We can help you align operations with California energy‑efficiency best practices and provide documentation useful for audits, commissioning, and continuous improvement programs.
