HVAC Know It All Podcast (HVAC Know It All )

In this Episode of the HVAC Know It All Podcast, Host Gary McCreadie is Joined by Jamie Kitchen, an HVAC Expert from Danfoss, to Break Down How Heat Pump Thermostatic Expansion Valves (TXVs) Work and Why Check Valves are Essential.

Jamie Kitchen explains the differences between heat pump Thermostatic Expansion Valves (TXVs) and straight cooling TXVs, why heat pump valves need built-in check valves, and how refrigerant flow reverses in heat pumps. They also discuss the evolution of expansion valves, the transition from pistons to TXVs and now to electronic expansion valves (EEVs), and why technicians often misdiagnose TXVs as the problem.

This episode is packed with technical knowledge, troubleshooting tips, and expert insights that will help HVAC pros better understand metering devices, improve system performance, and reduce misdiagnoses.

Jamie Kitchen shares insights on improving technician expertise and fostering a deeper understanding of heat pump TXVs and check valves. He highlights strategies such as mastering refrigerant flow dynamics, adopting universal TXV kits, and recognizing common misdiagnoses. This episode provides practical advice for HVAC professionals looking to enhance their troubleshooting skills, work more efficiently with modern TXVs, and stay ahead in the ever-evolving HVAC industry.
