"Good morning, My name is Tony. I'm a master HVAC technician. The other day we took the old condensing unit out on a Fisher air conditioner, which we just call condensing unit. We've already set the new one in place but we haven't connected it to the house at all. My copper, my refrigerant lines from here to my new unit. My high side, which is the smaller line and my suction line and then run new electrical. We've removed the old electrical, sealed tight and all last time I was here. Remove the old copper thing here, that was crudely put in and I ran new copper from here out to my condensing unit. This is a suction side line and this is my high side. When we worked you see how they had it covered in concrete and everything else. They actually had a kink in it, and damage too. I'm going to see if I can't clean that up and make it where it's going to be a good seal for me. I'll make sure I get a good seal, it just may take a little bit of fighting with it to get it straight. These are my saline torches. I got action and saline. Some people use a map gas, a smaller tank. I like this system, for me it works real well. Especially on this line set here, which is a seven eighths line set. It's a larger line set because we got a four ten unit, smaller units use a smaller line set than this is. What I'm calling line set, that's our copper from the inside. The outside, we call it the line set."
