Installing an Air Conditioning System: Brazing and Pressure Testing Part 3!

Installing an Air Conditioning System: Brazing and Pressure Testing Part 3! This is about an Air Conditioning System Replacement where I replace the Evaporator Coil, the Lineset, and the Condensor. This is Part 3 of the Brazing and Pressure Testing Procedure where I give a step-by-step process of connection of the refrigerant lines. I show proper 3cfh purging of the copper lines with nitrogen while brazing in order to eliminate oxidation, I show proper copper preparation, what to look for, and other tips along the way!
