In this HVAC Video, I go over how to Pressure Test Refrigeration Lines for an Air Conditioner. I show where to Find the Max Design Pressure, how long to hold the test, how to check the joints, and how to do an initial test before doing the higher nitrogen pressure test. Always follow manufacturers' instructions if they prescribe higher pressures or a longer wait time. I have the nitrogen tank set on the side so it was close up for the video but I usually stand it up vertically. Supervision is needed by a licensed HVACR Tech while performing tasks as Experience and Apprenticeship garners Wisdom and Safety.
