Commercial BAS Maintenance in Long Beach

What Our Commercial BAS Maintenance Includes

• Sensor calibration and validation for temperature, humidity, pressure, and CO2 to ensure accurate control responses.
• Sequence of operation verification and tuning to match design intent and real-world loads.
• Airside economizer optimization, demand-control ventilation, and ventilation resets for healthier, efficient buildings.
• VFD, actuator, and damper health checks to prevent failures and extend equipment life.
• Schedule alignment with occupancy patterns, holidays, demand response, and after-hours policies.
• Alarm rationalization, prioritization, and nuisance reduction to focus your team on true issues.
• Trend setup, analytics, and reporting that expose energy waste and comfort drift.
• Firmware and security updates, credential hygiene, and role-based access reviews.
• Network diagnostics across BACnet/IP, BACnet MS/TP, Modbus TCP/RTU, and LonWorks.
• Database backups and restore testing for supervisory platforms such as Niagara N4.
• Energy tune-ups aligned with ASHRAE guidelines and California Title 24 requirements.
• Inspection and replacement recommendations for sites utilizing AC PRO-sourced components and parts.

Our Process

• Discovery and site walk: review drawings, sequences, and past issues; identify risk and comfort hot spots.
• Data collection: pull trends, alarms, and network health; baseline energy and comfort KPIs.
• Optimization sprint: calibrate sensors, tune loops, refine resets, and clean up graphics and naming.
• Validation: functional tests under varied loads; verify economizer and ventilation performance.
• Reporting: deliver a clear action list, energy savings opportunities, and compliance notes.
• Follow-through: schedule corrective work, set new trend packs, and confirm backups.

Built for Long Beach Facilities

Coastal conditions, marine-layer temperature swings, and salt-air corrosion can destabilize controls and accelerate wear. Our Long Beach BAS maintenance program addresses these local realities: protective enclosures for sensitive devices, corrosion-aware inspection intervals, and ventilation strategies that balance comfort, air quality, and energy in waterfront environments. From Downtown Long Beach and Bixby Knolls to Belmont Shore and the Port-adjacent districts, we keep mission-critical spaces operating smoothly.
