"We're getting ready to pressure check the system with nitrogen. Actually a while ago I come out was putting a little nitrogen through it as I was soldering the joint in there that helps keep those joints cleaner. But now we'll pressurize it. Put my valve stems back in. Pressurize the system and check for leaks. This is my suction side here. My high side line. And here's my gages. So I'm going to turn my nitrogen on. And I'll start now putting nitrogen in the line right now and into my coil. Now I'm just over ninety pounds on my suction. And will look and see if it holds at ninety pounds. Looks like we're holding. But I'm going to let it set for a few minutes and make sure. And then we'll do, we'll put a vacuum, we'll dump the nitrogen out and put a vacuum pump on it. And I'll also check it for leaks too. And also get any moisture that's in the refrigerant lines or anything like that."
