Heat pump line set appeared to have been cut with a hacksaw rather than separating at joints. The refrigerant was either recovered or released into the atmosphere. It should have been pulled back into the condensor and valves closed. The valves were left open allowing moisture to contaminate the compressor lubricant.This eventually rendered the system inoperable.The lineset was, also, left open allowing moisture and dirt to enter the each pipe, possibly damaging the air handler. The house was purchased in May 2018 but prior to that, when we toured the house everything appeared to be in working order. The lineset was noticed first and covered with tape to prevent more moisture and dirt from entering. this was noticed in May, the valves being left open was noticed about two weeks later. I have no photos. I do have a receipt for the purchase of a 25 pound cylinder of r410 refrigerant. I had agreed to the reconnection of the heat pump as part of my responsibility ( i have a copy of the mechanical building permit) so we didnt notice the valves open and no refrigerant until later. I know there is a stiff fine for releasing refrigerant into the atmosphere. I would like to see repair or replacement of the affected parts. Have contacted Clayton three times to no avail
