If the suction pressure is 45 psi, (which converts to 22 ° F) and the suction temp is 32 ° F, the system still has 10 ° F of superheat. The fact that these readings are normal indicates the low suction pressure is not caused by low refrigerant, but insufficient heat getting to the evaporator. CAUSE #2: Defective, plugged, or undersized ...Hence, R410A refrigerant is considered safer than R22 refrigerant which is why it is a direct replacement for R22 refrigerant despite being slightly higher in GWP.
