2 year old unit stopped cooling, diagnosis was a small leak in the coil which ran up from the unit in my garage through the attic and back down the outer wall to the outside unit.
The repair consisted of not replacing the old coil line that went up through my attic but running a new one down along the back of my garage and drilling a new hole through the side of my house. The old coil line was left throughout and cut off on the outside, just hanging there. Is this the norm for replacing a leaking coil? At the very least, the new hole was not sealed (I can see light from the inside of my garage) and this seems improper. But what about the new extra coil line, new unsealed hole in the side of my house and leaving the old coil line? Couldn't the existing line have been repaired and/or replaced. It seems sloppy to me but I'm just a new home owner; any input? Thanks in advance.
