Preformed cooling maintenance on downstairs gas system 2022. I tested all electrical components on the inside unit. All tested within manufacturer specifications. I did notice the blower wheel to be dirty and could benefit from a pull and clean. Tightened all electrical connections. Temperature across the coil was at 18 degrees. Filter did not need to be changed at this time. I treated the drain line with total c. I proceeded outside to test all electrical components as well as the run and start amps for he compressor and fan motor. The capacitor was testing within manufacturer specifications range. I ohm’d out the Contactor and it was testing within range but it was testing closer to the lower side at 12 ohms. Run and start amps for both the fan and compressor tested within manufacturer specifications range. I rinsed the outdoor coil but it could also benefit from a chemical wash. Unit was cooling upon departure.
