Ac maintenance in Murrayville, Georgia. 7 systems. Added chlorine tablets to condensate pumps. Tested mechanical and electrical components. Found main house basement evaporater coil to be rusty, corroded and therefore likely to leak refrigerant. Found upstairs dual capacitor to be bad (45/5 mfd), no reading on compressor side at all. Replaced main house upstairs dual capacitor. Changed main level and upstairs filter for main house. Systems are cooling at this time. For the main house- upstairs system is in the attic, main level and basement systems are in the basement. For guest house there are two upstairs units located in the attic, one in a closet in the basement and another in the tool room.
