And why did it fail? Comp permanently open at IOL.
Changing out a 3 ton Goodman system in an upstairs lake house and when I removed the condenser, I noticed the armaflex had a crease in it and it moved easily. Found a major kink in the line and will have to cut up the wall to get to good copper. No way to replace this copper without major retrofitting (No attic and up stairs between floors).
Then inside with the air handler out, I saw another crease in the armaflex- yep- another kink.
Been like this since day one. Customer said it never cooled much. Amazing it lasted this long.
