Yes so far it has
been a very expensive hole. Still not as much as a new unit but it still remains to be seen whether or not I'll need to buy one. I was enlarging a hole that was already present in the cabinet when the drill bit caught and went straight through a condenser line. I thought I was going to be sick...
Anyway here is what I installed that caused this chain of events.
My A/C guy wanted to replace the unit and he may be right. I used to be an auto mechanic and we would repair leaky A/C lines all the time with no problems. However this one has been hard to get to and apparently the compression fitting wasn't the way to go. Brazing or flared fittings seem to be much more reliable and so I decided that flaring the lines would be much easier than trying to braze aluminum.
