Customer said that unit is not keeping up the temp. After finishing diagnosing found out that unit almost lost half of the Freon and found leak in evaporation coil. No oil sign on condenser coil. Customer agreed to replace the evaporation coil. We have to schedule the repair asap we have the coil. Customer is without ac. Came back at 08/05/25 and found unit completely 0 on Freon. Replaced coil . Pressure test it up to 400 push make sure there is no other leak and it hold . Added up to 12 lbs 1.5 lb more than factory charge because there is a long line set. Turned on the unit and make sure that pressures , subcool and DT are at the right level. Unit is operating as designed now
