We walk through key measurements from the compressor through the system, including suction pressure/temperature, discharge temperature, volts/amps, oil temperature, condenser inlet/outlet conditions, receiver inlet/outlet checks, liquid line temperature changes, and evaporator outlet pressure/temperature to verify subcooling and superheat. Write these checkpoints down, learn from other techs, and leverage data to spot trends and root causes to speed up service and reduce callbacks.
