Commercial Daikin VAV Box Repair in Burbank, CA

#1 AC Guys is the Burbank partner facilities trust for accurate, lasting repair of Daikin Variable Air Volume (VAV) boxes. We combine precision engineering with practical field experience to restore airflow control, temperature stability, and indoor air quality—reducing hot/cold calls while improving energy performance.

What we repair and optimize on Daikin VAV terminals

• Damper actuators, linkages, and blade alignment
• Airflow sensors, flow rings, and pressure pickups (cleaning, replacement, recalibration)
• Discharge air, space, and duct temperature sensors (testing and re‑mapping)
• Reheat systems: electric elements, hot‑water valves, and control sequencing
• Controller programming, setpoints, schedules, and overrides
• BACnet MS/TP and BACnet/IP communication, addressing, and BMS integration
• Noise, vibration, and airflow balancing across zones
• Title 24 and ASHRAE 62.1 ventilation compliance checks

Whether your building uses a central air handler with Daikin VAV terminals or a mixed fleet, we isolate root causes instead of masking symptoms—so fixes hold under real‑world loads.

Signs your VAV boxes need service

• Hot/cold complaints in certain zones or at specific times of day
• Low airflow alarms, whistling, or excessive noise from terminals
• Damper stuck open/closed or actuators hunting
• Reheat not engaging or short‑cycling
• Sensor drift leading to inconsistent readings and comfort issues
• BMS trending shows unstable CFM, temperature, or communication faults

If any of these sound familiar, our team can quickly pinpoint faults, provide a clear estimate, and perform code‑compliant repairs that restore stable, efficient operation.

Our repair and recommissioning process

• Diagnostic scan: inspect terminals, trend data, verify addressing, and review alarms
• Functional testing: command damper travel, verify actuator torque, and confirm endstops
• Airflow calibration: reset K‑factors, correct sensor placement, and validate CFM
• Reheat verification: stage electric or modulate hot‑water valves, test safeties
• Controls tuning: optimize control loops, changeover logic, and schedules
• Zone balancing: correct distribution for comfort and ventilation compliance
• Documentation: before/after readings, photos, and punch‑list for facility records

We coordinate with your building engineer and BMS vendor to minimize downtime and maintain accurate trending for future maintenance.
