Tech performed CMA inspection on two systems. Tech adjusted belt tension on Trane package unit, also wrapped wiring in compressor compartment to prevent any potential shorts in the future. Tech found no challenges with this system. Amp draws and capacitors tested within spec. System is heating and cooling properly. Tech inspected Trane split system and found system running fine in cool mode with proper refrigerant pressures. However, once switching to heat mode the system cuts out on high head pressure. Suction pressure is within spec but head pressure gradually rises above 500 until pressure switch opens. Airflow is good, tech found a 6 degree temp difference across filter drier. Drier is restricted, indoor and outdoor TXV are operating properly. Recommend replacing filter drier. Amp draws are within spec, Condensor fan motor is almost over amping. 5MFD run cap for fan motor is testing weak, recommend replacing. Compressor run cap (70MFD) is testing within range. Trane split system is
