The low pressure side carries R22 gas while the high pressure line carries R22 in a liquid state. R22 changes from a liquid to a gas in the evaporator coils of the air handler. Normal temperatures: With compressor running and as reference, on a 90 degree F. day: - Goodman runs 45degrees F on low pressure side and 115degrees F on high pressure side.In this case, this pressure (46 psig) will correspond to a temperature of 23 degrees, which is 15 degrees cooler than the lowest desired box temperature of 38 degrees. If the pressure control has a high event (cut-in) and a differential setting, the cut-in will be set at 68 psig and the differential will be set at 22 psig (68 psig - 46 psig).R410a suction pressure may be around 120psi, and R410a head pressure may be anywhere from 225psi to 350psi. Many conditions could apply here, there’s absolutely ‘no’ set point pressure for 410a, r22, or anything else.

Step 12. Compare the super-heat reading to the gauge's psi reading. If the super-heat reading is more than 20 degrees above the P/T chart's reading, then add R-22 until the super-heating reading reaches the optimal range -- between 8- and 18-degree super-heat, depending on the environmental conditions. Many technicians charge the system until ...

The minimum, recommended low pressure cut-out switch settings for Air-conditioning and chiller application are 55 psig (3.8 bar) for R410A, 25 psig (1.7 bar) for R22 and R407C, and 10 psig (0.7 bar) for R134a.
