Commercial Variable Air Volume (VAV) Box Repair in Oxnard

Precision VAV Box Repair for Commercial Facilities

When a Variable Air Volume (VAV) box fails, occupants feel it first—hot and cold spots, noise, or poor airflow. Our Oxnard commercial VAV repair team diagnoses the entire control loop: damper mechanics, actuator torque, reheat operation, temperature and pressure sensing, and DDC sequences. We address failures at the component and system levels to restore comfort, efficiency, and stability across zones.

• Actuator and damper repair or replacement
• Reheat coil service (electric or hot water) and limit checks
• Sensor testing, calibration, and replacement
• Controller troubleshooting and sequence validation
• Airflow setpoint verification and balancing support
• Noise and vibration mitigation at the box
• Leak sealing and insulation touch‑ups at terminals

Every repair is verified with live readings and functional testing against design intent and applicable California Title 24 requirements, helping you reduce energy use while improving indoor comfort.

Our Oxnard-Focused Process

We tailor our approach to the realities of Oxnard’s commercial properties—medical offices, Class A buildings, retail centers, schools, light industrial, and more. Each service call follows a clear, engineered workflow for predictable results.

• Discovery: Interview facility staff, review comfort complaints, and collect available VAV schedules or sequences.
• Diagnostics: Measure supply temps, static pressure, cfms, damper position, and reheat behavior; check sensors and controls.
• Targeted Repair: Replace or repair failed actuators, linkages, sensors, and reheat components; correct wiring and configuration issues.
• Calibration & Setups: Re‑establish minimums/maximums, tune PIDs where applicable, and confirm airflow to design.
• Verification: Zone walk‑through, data capture, and a clear report with before/after readings for your records.

Need multi‑box remediation? We can phase work to minimize disruption, coordinate with your BAS/BMS provider, and support Testing, Adjusting, and Balancing (TAB) teams.
