No cooling, did a complete evaluation of ACC system. Found evaporator coil freezing up. Checked refrigerant pressures. Getting very low suction pressure with a high head pressure. TXV is restricted, also capillary tubes on evaporator coil are rubbing against metal and are very corroded. Gave client options to repair system, however, recommended replacing system due to condition and cost of repairs. Client decided to replace system at this time. We are installing new packaged heat pump system on Wednesday, July 2. Client paid $2637 down and finance $6000 through upgrade.
