When technician arrived the AC downstairs was not working thermostat was blank. Technician went to attic and found plugged drain, found the drain lines run into masterbath sink so I removed that and found plugged line going into the sink so I cleared the plugged line re installed the flex hose and water drained through it. Technician got some bleach water from homeowner and flushed both attic systems. Then technician checked coils, blower wheel, temperature splits, refrigerant pressures including superheat and subcool, checked capacitors and contactor, and washed outdoor coil. 70/5 capacitor tested at 68.4 and 5 and contactor starting to pit will quote to customer. Homeowner asked for technician to install the new contactor and dual run capacitor so I replaced and tested. Unit is good to go
