A friend had me remove a section of drywall to see why there was moisture damage at the baseboard height on one wall.
I found the refrigerant line that runs from outside compressor to attic mounted air handler was poorly insulated and dripping in the wall cavity.
Upon close inspection I also found that the larger copper line,the suction line, was nearly flat where a 90 degree turn to the outside was bent into it.
I estimate 10% of the capacity of the line is available due to the severity of this bend.
The A/C is brand new and cooling well.
The Home was built 15 years ago and this is the third AC replacement. The kinked line was done during construction.
I believe this kinked line is the cause of premature failure of the last 2 units and if left unfixed will lead to a third unit failing.
Tell me what can happen to a system over time in a case where the 3/4 suction line is crushed like this.
Edit: the kinked section was cut out and new line put in.
