Aluminum Evaporator Coil
The evaporator coil is susceptible to formicary corrosion, which creates microscopic pits in the tubing and leads to a complete loss of refrigerant charge. When the system lacks refrigerant, the compressor cannot create the pressure differential necessary for the Joule-Thomson effect, resulting in no heat exchange. The system 'runs' as the control board attempts to meet the thermostat demand by engaging the blower and outdoor fans, but the air remains at ambient temperature.
