One of the leading causes of low suction pressure is refrigerant leakage. When refrigerant leaks occur, the system’s refrigerant charge decreases, resulting in reduced pressure levels. Leaks can occur at various points, including connections, joints, valves, or even within the coils themselves. 2. Dirty Evaporator or Condenser Coils.The most fundamental difference between high and low-pressure systems is the movement of air. In high-pressure systems, air descends toward the ground, resulting in stable atmospheric conditions. In low-pressure systems, air rises, leading to more unstable atmospheric conditions. Air also always moves from high pressure to …180 suction line pressure 320 discharge 10 degree temp split. No temp difference across the filter drier.
