I changed my blower motor out and in the process a wire arced out on a small copper line and blew a hole in it. What leaked out? I have since soldered up the hole and have not run the unit. I fear that if it was freon that leaked out it would damage unit by running it. It wasn't a cold gas though cause I put electrical tape around the hole as it was leaking just to try and keep dirt and outside air from it. The big copper line with insulation around it is fine.
It wasn't liquid. I figured it was freon but it wasn't cool to touch. On the inside of my house at the air handler there are two copper pipes that run up to my coil. One is big and insulated the one right next to it also runs to coil but is only like a 1/4 inch in diameter more or less. This small one is the one I blew a hole in. It was some type of gas or air. I taped it as it was leaking out but like I said it wasn't cold. Here's my worse thought, if it was freon then I will have to pay to vacume and dry then recharge which is about 700.00 dollars. 70.00 x 5lbs of freon 90.00 for them to drive out rest is labor. Just was hoping it was not freon that leaked cause it would save some trouble. I can weld pipe and work metal but I don't do freon lol.
