Went for a maintenance call today. Tested for static pressure, both system are failing when in cool. Tested for amperage is passing for blower, compressor and fan for both systems. Upstairs capacitor is fail and main floor is passing. Temp split passes for upstairs and fails for main floor. Refrigerant is passing for upstairs and main floor is failing. Will recommend to replace capacitor and add refrigerant. Main floor coil is rusted and the cause for the refrigerant to leak. Did replace capacitor and added refrigerant. Both system are up and running before leaving. Thank you for choosing LBA services-Johann
