Advanced VRF/VRV Diagnostics

We don’t guess—we measure. Our technicians use advanced instrumentation and proven test procedures to find true root causes, not just symptoms. We verify communication integrity, electronic expansion valve operation, refrigerant mass flow, superheat/subcooling, fan performance, and sensor accuracy. We pressure‑test with nitrogen, evacuate to deep vacuum, and confirm system balance before returning your equipment to service.

Common Fujitsu VRF/VRV Issues We Repair

• Inverter PCB and outdoor drive failures impacting compressor speed and capacity.
• Indoor comfort drift from EEV malfunction, sensor drift, or airflow restrictions.
• Communication bus faults and addressing issues across multi‑zone networks.
• Heat recovery and branch box problems, including valve leakage or sticking.
• Refrigerant leaks at flare joints, coil connections, or service ports.
• Oil return concerns, compressor protection trips, and nuisance lockouts.
• Defrost irregularities, low heating output, or seasonal performance loss.
• Vibration, noise, and balance issues affecting occupant comfort.
