Kink in the large line of the lineset right where it comes out of the foundation. Im sure its been there since the lineset was installed 18 years ago.
What would this kink cause?? With the new system installed the house was 72 and 38RH but the compressor was loud after 4 days. Would the kink thats been there for 18 years all of a sudden made the new scroll compressor run loud after it had run quiet and cooled the house fine for 4 days??
