Burbank Commercial VAV Box Repair — Fujitsu Factory‑Trained Engineers

Reliable VAV Performance Starts with Engineer‑Level Diagnostics

Uneven temperatures, noise, and rising energy bills often point to a failing VAV box. Our engineer‑led process pinpoints root causes, repairs precisely, and validates results with data, not guesswork.

Common VAV Symptoms We Fix

• Hot/cold spots, poor zoning, or rooms that never meet setpoint
• Frequent hunting or short cycling due to bad tuning
• Stuck or slow dampers, failed actuators, or broken linkages
• Airflow sensor or transducer drift causing incorrect CFM
• Reheat coil failures (electric or hydronic) and valve/relay issues
• High noise from turbulent flow, loose insulation, or worn parts
• BAS/DDC alarms, BACnet communication errors, or mapping faults

Each finding is documented and explained so you can make confident, cost‑effective decisions.

Fujitsu Expertise and Intelligent Integration

Our team is factory‑trained by Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China). That depth matters when integrating VAV zones with VRF/heat pump systems, optimizing supply air temperatures, and coordinating controls strategies. In Burbank’s studio and office buildings—where quiet operation and precise comfort are non‑negotiable—we align VAV logic, setpoints, and reheat with upstream equipment and your BAS for seamless performance.

What We Repair, Calibrate, and Optimize

• Damper actuators, linkages, and spring returns
• Airflow pickup tubes, velocity pressure sensors, and transducers
• Controller boards, thermostats, zone sensors, and relays
• Electric reheat elements, hydronic coils, valves, and actuators
• Insulation, sound attenuation, and vibration/noise issues
• CFM setpoint tuning, k‑factor checks, and pressure‑independent control
• BAS/DDC/BACnet point verification, trend setup, and alarm logic

Every repair is followed by calibration and functional testing so zones deliver the CFM they’re designed for—at the energy cost you expect.

Balanced Airflow and Commissioning That Holds

We don’t just swap parts. We restore the engineered intent with a commissioning mindset:

• Measure and verify actual airflow versus design, then correct
• Optimize minimum and maximum CFM for comfort and savings
• Coordinate supply temperature with reheat strategies
• Validate sequences of operation and damper modulation
• Trend critical points to prove stability over time

Expect clear reports and actionable recommendations for ongoing reliability.
