A/C works quietly and dependably
The installation was challenging as the existing unit was installed before the wall was built. The installers assessed the situation and made the most reasonable decision as to how to proceed. The wall was carefully removed (more challenges) and the old was removed and new put in place. The surrounding area was appropriately protected (but of course dust was everywhere). They made sure the area was clean before they left.
The A/C is working well and is much quieter than the old installation.
