Arrived at customer's residence and found system completely out of refrigerant. During leak inspection, found rubbed out compressor and CFM wiring on liquid lineset. Repaired wiring, checked condition of both motors, repaired the lineset leak, replaced filter drier, pressure tested, pulled a deep vacuum, and recharged 10.5 lb of R-410A into the system. Strapped all adjacent wiring in order to prevent further rubouts. Work completed. Service warranty.
