If the "tech" had bothered to check the evap coil *before* replacing the
compressor, he would have probably seen that the tube sheets were rusted to
hell and would have at least checked the damn thing before installing the
new compressor. How hard is it to put a little trash gas from the recovery
can in the system to do a leak check??
Its gonna be evacuated and have a new filter/drier installed anyway.
