Performed AC diagnostic on 2007 carrier condenser. Prior to diagnostic Mac had stated that home warranty had done a diagnosis on the system and recommended that he replaced everything due to it not working. I begin my diagnostic at the outdoor unit and found that it was not energized with 240 V. Capacitor was also replaced and left accidentally buy home warranty company. Found that outdoor breaker coming from panel were miss labeled And breaker for AC was off. Flipped the breaker back in the on position And system fired up properly. Compressor was pulling 9 Amps considering at the highest is 14. System also contained R22 refrigerant which was completely phased out January 1, 2020. Contactor was pitted.

Also found signs of water leakage coming from primary pan of the evap coil due to it rusting out over the years. Ultimately system worked but Mac would like to replace the system once he moves into
