At Maqsood and Sons, we understand that VRF systems, while highly efficient, can face several technical challenges. That’s why our certified technicians in Islamabad & Rawalpindi are trained to diagnose and resolve every issue swiftly.
Different rooms stay warmer or cooler due to refrigerant imbalances, sensor malfunctions, or zoning logic errors. We inspect sensors, recalibrate refrigerant levels, and update control settings to fix it.
VRF systems display fault codes like U4 (indoor-to-outdoor communication issue), E7 (fan motor fault), or L5 (compressor overload). Maqsood and sons experts use brand-specific tools (e.g., Daikin, LG, Gree) to interpret these codes accurately and repair the correct components.
Clogged coils, poor airflow, or outdoor fan failures can cause outdoor units to overheat. We perform coil cleaning, fan motor repairs, and ensure proper refrigerant flow to restore normal operation.
During peak heat, VRF systems can shut off due to high load, low gas, or electrical issues. We conduct system diagnostics, check circuit parameters, and optimize refrigerant charge to safeguard performance.
VRF systems are vulnerable to small leaks due to their different pipe connections. With sensitive leak detectors and pressure testing, with our tailored vrf ac service we try to locate leaks, reseal connections, and recharge exactly to spec.
Clogged condensate drains or disconnected lines can cause overflow. We clear drain traps, realign piping, and ensure proper drainage to prevent water damage and avoid errors like “Drain Level Control Malfunction.”
7. Temperature Swings Between Rooms
If temperature fluctuates between zones, the root causes might be refrigerant imbalance, control board issues, or sensor mismatches. Our vrf ac service includes zoning recalibration, thermostat tests, and load balancing to get your system back to smooth operation.
