Upon arrival spoke with customer and he had shut system breaker off for outdoor upstairs. Went upstairs, filters are clear. Blower and coil are clean, found no leaks on coil. Drain line is clear. Went outside and found capacitor had gone bad, replaced capacitor and started system. Found power on disconnect for upstairs. Customer had turned power off to downstairs outdoor. Turned power on and outdoor downstairs came right on. Let upstairs run contacter checked out good. Fan amped at 1.1amps. Compressor amped at 6.1amps. Refrigerant levels where 65/201. System is cooling properly at this time. Priced up membership for customer and also explained with the age of these systems they can fail at any time and I would look at replacement coming soon.
