Upon arrival turned on the system in cooling then checked pressures. Pressures were low and within minutes noticed frost on the suction line at the condenser. When into the attic and found the coil was also frosted over. Turned system off then performed electronic leak search. Finding leak multiple leaks at the condenser coil. The system is covered under service warranty until April 29, 2020. Will have office order new condenser coil and call back to schedule return visit for repair.
