Upon arrival I went to roof with Nate. Found circuit 2 operating with 24 degree delta at Evap coil, unit only pulls in fresh air from outside, EAT 96 LAT 72. Circuit 2 running at 100psi suction and 350psi discharge. Refrigerant pressures and temps look ok, not performing leak search on this circuit because I have normal pressures and temps. Put gauges on circuit 1 to find it flat. Opened up all panels to find evap coil had been previously cut open and pipes still open. Coil is unrepairable and needs to be replaced. Sent picture to Nate and also uploading to file. Quoting customer to replace Evap coil. Can not determine if Compressor 1 runs until coil is replaced and refrigerant circuit closed. Found outdoor coil needs to be cleaned, causing higher head pressure. Also found condenser fan motor 2 was rattling loudly. Adjusted height of blade to stop rattle. Finally I found gas valve in off position. Inspected heat exchanger but found no cracks and barely any rust. Unclear if heat works a
