Performed Tune up on 2019 Carrier system. Checked all components of the Airhandler and found no issues with the functionalities of the Airhandler. Checked all components of the Heatpump and found two issues. Could not force Heatpump into defrost mode so not 100% confirmed that the system will properly go into defrost if needed, also found dual run cap to be just outside of the manufacture tolerance. Talked with customer about issues and recommendations, customer does not want to do anything at this time.
