Ac maintenance in Lilburn, Georgia. Two systems. Changed filters. Tested mechanical and electrical components. Found upstairs blower capacitor to be weak (4 mfd). Found upstairs system to be completely void of r22 refrigerant. Upstairs main electrical switch is burnt and in bad shape. Due to age and condition of upstairs system, recommend upgrading system to a more reliable and more efficient system. Chemically washed condenser coils. Main level system is cooling at this time. Set up consultation for upstairs system. Thank you so much for your buisiness today!
