Heat pump was working properly when I arrived so I put heat pump through defrost mode more than once and ran heat pump in charge mode as well. I checked all amp draws and components. I tested refrigerant pressures. I tested temp split as well. Heat pump is running within manufacture specifications. We tested out the furnace today as well and put in a different air filter which lowered the airflow pressure on the system. Inducer capacitor is testing out of range so we will need to return with a new one and replace it under part and labor warranty. Furnace is running within manufacturer specifications at departure.
