Performed maintenance on 13 year old Rheem system. Cycled system for cooling . Checked system electrical and components. Pulled condenser fan motor and thoroughly washed out condenser coil inside and out. Refrigerant pressures are in range and system is producing proper temperature split. Fully evaluated system, concerns are as follows: 1. Capacitor for compressor has fallen out of allowed range. 2. Condenser fan motor has started to leak oil near shaft. This can cause motor to seize up due to lack of lubrication 3. Primary motor control is starting to hum at low voltage coil. Went over findings and recommendations with homeowner, wife not present for appointment. Also went over recommendations from previous visit. Homeowner wants to hold off on any work today since unit is still operating and they hardly ever use it. Cycled system. System is operational upon departure.
