Began by performing diagnostics on the American Standard heat pump unit at the main house. I found that the indoor unit was running so I went outside. The fan was running but the compressor was not pumping refrigerant. Upon closer inspection, I found that the system had a failed capacitor and two melted wires coming from the contactor. I was able to repair one wire and replace the other, along with the capacitor. After replacing the capacitor, I fired the system off and everything worked properly in heat mode. I then performed the rest of the maintenance on the main system as well as the Daikin mini split for the pool house. Both systems are working properly at this time. Thank you for your business.
