Apr 15, 2021 · Trying to diagnose a 2 year old Amana heat pump with high suction and discharge pressures in heat mode. ASZ 16 SEER OD unit matched up with an ARUF Goodman piston air handler. Both are 2 ton 410A units. 10kw heat kit and lineset is about 20ft long. HEAT MODE Unit is tripping out on high head(600psi). Jun 6, 2019 · In the case of heat pump units running in heat mode, the most common causes are dirty air filters or other indoor airflow restrictions (because the condenser is now inside during heat mode). In short, high discharge temp can commonly be caused by: Low charge (high suction superheat, low suction pressure, low subcool) Severe overcharge.The calculation for charging refrigerant is critical in heating mode. The overcharging of the refrigerant leads to many unwanted problems in the system. One of the primary cause of head pressure to be high is the overcharging of the refrigerant. High head pressure on heat pump. The high head pressure in any device deteriorates the performance.Heat pumps are an energy-efficient way to heat and cool your home. They work by transferring heat from one area to another, which can help reduce your energy bills. But with so many different types of heat pumps available, it can be difficu...
