Components We Diagnose
Compressor
The heart of the cooling system — we test for electrical fault, mechanical wear, and refrigerant pressure.
Condenser Coils
Critical for heat exchange. Dust buildup causes overheating and poor cooling.
Evaporator Fan
Circulates cold air inside the cabinet. Bearing failure causes noise and uneven cooling.
Thermostat / Temperature Sensor
Controls when the compressor cycles. A faulty sensor leads to overcooling or undercooling.
Control Board
The electronic brain. We diagnose error codes and replace failed boards with OEM parts.
