Upon arrival technician found a 410 a system from 2006 with a failed evap coil or failed TXV that is causing a failed evap coil, and then overcharged condenser to compensate for the failed evap coil. The failed coil is causing the system to seem low on refrigerant. So when other techs put refrigerant in the system it raises the head pressure and causes the system to shut off with 600 psi or more. The system is currently at 115/530 psi. Considering the condition of the system the system should be replaced.
