Watch Troubleshooting Heat Pump Refrigerant Systems

This video offers a practical approach to understanding mechanical refrigeration as it applies to residential heat pump operation. Included in the video are real time demonstrations of normal equipment operation relative to system pressures, superheat and subcooling, as well as demonstrations of the most frequently occurring failure situations: low charge, over charge, low evaporator air, low condenser air, liquid line restrictions and TXV failures. The video is a valuable tool for increasing your analysis and diagnostic skills.
