Found system to have a weak run capacitor for the blower motor, it is pulling 6.4/7.5 mfd. Changed for new per customer approval. Cleaned indoor and outdoor coils as well as drain line and treated drain pan with antimicrobial agent. Checked all electrical connections and amp draws as well as refrigerant circuit pressures and temperatures. Found compressor to be running with slightly high amps, capacitor is good. This is to be expected on a 19 year old system. System is performing and draining the way it should be.
