Commercial Variable Air Volume (VAV) Box Repair in Burbank

Why VAV Boxes Fail and How It Affects Your Building

VAV boxes regulate zone airflow and temperature, so even minor faults ripple through comfort, noise levels, and energy use. In Burbank’s dynamic commercial environments—offices, studios, and retail—common issues include worn damper actuators, stuck or misaligned blades, failed or drifting differential pressure sensors, compromised insulation, reheat coil failures, and BAS/DDC setpoint or communication errors. The result: hot/cold spots, poor ventilation, rising utility bills, and comfort complaints.

• Temperature swings and occupant discomfort from improper airflow or failed reheat control
• Excess fan energy and noise when dampers fail to modulate correctly
• IAQ shortfalls from inadequate outside air or miscalibrated sensors
• Code and compliance risks when airflow and ventilation aren’t verified

Our Engineering‑Driven Diagnostic Process

We approach every VAV repair with an engineering mindset built over 80+ years and four generations. Our process focuses on root cause, not guesswork, delivering reliable repairs and measurable results.

• System review: drawings, sequences, recent BAS trends, and service history
• Live testing: damper operation, actuator torque, sensor accuracy, and control response
• Airflow verification: pitot/flow hood testing and pressure readings against design specs
• Electrical and controls check: power, wiring, terminations, and DDC point mapping
• Calibration: controller tuning, setpoint validation, and final functional testing
• Documentation: before/after readings, findings, and recommendations

Repairs and Calibrations We Perform

• Damper and blade alignment, lubrication, and sealing to eliminate leakage and noise
• Actuator replacement and torque verification for smooth modulation
• Pressure sensor and transducer replacement with precise calibration
• Controller repair/replacement and reprogramming to restore sequences
• Reheat coil repairs (electric/hot‑water), valve actuators, and overheat protections
• Sound attenuation, insulation repair, and panel sealing to restore quiet operation
• Airflow balancing to design CFM, including minimum and maximum flow setpoints

BAS/DDC Integration and Controls

VAV performance is only as good as its controls. We diagnose communication issues, incorrect setpoints, and unstable loops, then align sequences with your building’s needs. Our team ensures each VAV box communicates reliably with your BAS/DDC, trends correctly, and maintains pressure‑independent control where required. Expect clear labeling, updated point lists, and verified alarms to simplify ongoing facility management.

Proactive Upgrades for Comfort, IAQ, and Efficiency

• Conversion from pneumatic to DDC for tighter control and analytics
• Pressure‑independent retrofit kits for consistent airflow despite duct pressure changes
• CO2 sensor integration for demand‑controlled ventilation and better IAQ
• Reheat optimization and high‑efficiency components to reduce energy spend
• Insulation upgrades and leakage sealing to cut noise and thermal loss
• Portfolio‑wide testing and standardization for multi‑tenant buildings
