Preformed cooling maintenance. Tested inside units electrical components. All components tested within manufacturer specifications. Treated drain lines with total c. Replaced filter for client 16x25x1. Temperature split across the coil inside is 19 degrees, 54 supply temperature and 73 return temperature. I proceeded outside to test all the electrical components outside, along with run and start amps of the fan motor and compressor motor. Capacitor tested within manufacturer specifications. Contactor was testing on the high side of manufacturer specifications at 20.4 ohms. All run and start amps are within manufacturer specifications. I provided an estimate for a new Contactor. I rinsed outdoor coils. Unit was cooling upon departure.
