This estimate is to replace and out of warranty evaporator coil. This includes pumping down refrigerant, removing the faulty coil and installing a new OEM coil, pressure testing with nitrogen and then placing system on vacuum. Releasing refrigerant. Any additional refrigerant is needed it will be charged separately. Thurs Aug 31st- Jess- Returned today and pumped refrigerant down. Locked refrigerant off in condensing unit. Removed faulty evaporator coil and installed new OEM evaporator coil. Pressure tested with nitrogen and then placed system on vacuum to 497 µm.
