Common Lennox VRF/VRV Issues We Diagnose and Repair

• Communication and network faults between outdoor, branch/selector boxes, and indoor units
• Inverter and drive errors, compressor lockouts, and overcurrent conditions
• Heat-recovery mode faults, zone temperature imbalances, and changeover issues
• EEV/expansion control problems, thermistor/sensor failures, control board defects
• Refrigerant leaks, charge inaccuracies, oil return challenges, and capacity loss
• Indoor unit failures: fan motors, coil fouling, condensate drain/pump problems
• Outdoor unit issues: coil contamination, fan performance, ambient/defrost logic
• BMS integration faults, setpoint conflicts, scheduling and occupancy control errors

Our approach safeguards compressors and electronics while restoring stable operation with verified superheat/subcooling, proper airflow, and correct charge.
