Indoor Evaporator Coil
The cooling cycle depends on the evaporation of refrigerant within this coil to absorb heat. A leak in the coil's aluminum or copper tubing results in a loss of refrigerant charge, preventing the system from reaching the necessary saturation temperature. The unit will continue to 'run' as the inverter attempts to reach the setpoint, but no sensible cooling will occur.

Electronic Expansion Valve (EEV)
The EEV is a precision metering device that regulates refrigerant flow based on signals from the controller. If the internal stepper motor fails or the valve sticks, refrigerant flow to the evaporator is choked. This results in the compressor running without the ability to circulate enough refrigerant to facilitate heat exchange.

High-Efficiency Media Air Filter
A severely restricted filter reduces airflow over the evaporator coil below the critical threshold. This leads to the coil temperature dropping below the dew point and freezing, creating a block of ice that prevents further heat absorption. The system runs continuously, but the ice layer insulates the air from the refrigerant, resulting in no cold air delivery.
