On arrival, I found that the outdoor fan motor was running, however the compressor was not pumping any refrigerant throughout the refrigerant circuit. I tested the run capacitor and found that it had failed across the HERM terminal. I checked up in the attic and verified the air filter was not dirty and also tested the fresh air damper system as well. I went over my findings with the homeowner and they chose to replace the capacitor. Installed a new run capacitor at the outdoor condenser. Cycled high voltage power and checked over operations. Tested and verified refrigerant was operating at a 13°SH and a 13°SC value. Indoor air temp prior to leaving was around 80° at 80% humidity. I did let them know it would take some time to cool the house down as it has to remove all the heat and humidity from the home. Everything is working at this time.
