Cleaning Home Air Conditioner Joints

Video Transcript

"Now I'm cleaning the ends of it with some just some emery cloth. Plumber's. We want a real good clean joint here. So our solder sits good and so there are no problems. Now I use a fifty-fifty silver solder. It's quite expensive, but it's good. It's the best I can get. You don't want to use, I don't use, there's some other brands out there. Some of it's cheaper that I don't use. You definitely don't want to use lead on refrigerant lines. That's for water lines. It's cheaper but it's not going to give you the good solder joints you've got to have for your high pressures that you're going to have on a refrigerant line. Now let's see if I can form this to make it fit where I want it to fit. And what all I'm going to have to do here. OK, now I've got my coupling started on there. It's going to have to go a little further, but I'll heat it up and it'll slide on. I happen to have a kink, a little offset in my pipe anyway that's going to line up to where I can line it up without using my forty five here. I'm going to be able to use the pipe itself. The forty five in it I believe. I'm going to go ahead and unsolder this joint. This is my high side line. I'm going to go ahead and take it off. I've also got to take and remove my refrigeration caps. Because they will melt of course, the plastic. And I'm also going to remove the valve stems that's in here. Now these two, these are our valves. This is the high side and low side valves. And right now the Freon for this unit is in the unit. These are shut off and they're closed. They're screwed all the way down here. And since they're closed there's no pressure on these valves stems. And I can take and take the valve stems out. If I left those valve stems in there and tried to solder this I would damage those valve stems. And I don't want to do that. Because then they would leak. And that's just like a valve stem on an automobile's tire, for bicycle or whatever like that. There we go."
