Arrived to our clients home. For the unit not cooling properly. On arrival the unit was off. I proceeded to turn the thermostat on and proceeded into the attic. I did a visual inspection on the air filter and ensured the indoor unit was on and running. I then went outside to the outdoor heat pump. I found the compressor was not running due to a failed capacitor. I checked other electrical components and ensured there was standing refrigerant pressures. I showed my finding to our client and they elected to replace the capacitor only today. They do have a maintenance plan with another company but want to check the status before potentially switch over to us. Once the work was completed I went back inside to test the temperature drop and checked refrigerant pressures again. The system is under a lot of heat load and will take a few hours to reach the desired temperature. The compressor is starting at 74 amps which is more than 50% its capacity, I am recommending a hard start kit also. T
