I found the leak before it cause major damage it must have bust right before I got back. Shut the water off at the road and knocked a whole in the drywall to let the water out so it would not fall on my head while I looked for the leak. I had to take down some drywall from the celling to find the pipe. Now for the heat going to have to replace the whole unit. It was going to cost almost as much to fix this as to replace it. The unit has struggled the last couple of summers so I knew it almost done but was hoping for one more year. Harbone I was concerned about electricity while I was pulling down the drywall. I did not think there were any wires in the area but I did not know for sure. I got the first piece down were I could see what was behind there and all was clear of wires.
