Just had a new split system (1.5 ton) system installed for my upstairs. Had to run about 80' of new copper line. The gas return is 3/4" copper rubber covered tubing.
I was very careful to minimize bends/and the use of copper 90s to keep the flow smooth and unrestricted. Despite this the installer damaged the 3/4 inch line where it came out of wall to attach to compressor/condenser.
There is a dent of 1/8" to 3'16" now in the copper line. Should I have them come back to fix this or is this a negligible thing?
