Hvac Know It All Podcast

In this episode of the HVAC Know It All Podcast, host Gary McCreadie talks with John Davidson, Regional Trainer at Fujitsu General America, Inc. John explains how heat pumps work in cold climates by using refrigerant technology to move heat from outside to inside. He discusses the role of coil temperature, pressure, and energy transfer in the heating process. The episode also covers inverter technology, the importance of base pan heaters, and how matched air handlers improve system efficiency. John shares tips for choosing between dual-fuel and all-electric setups based on cost, climate, and home design. In this conversation, John explains how heat pumps use refrigerant and pressure changes to move heat in cold weather. He gives clear examples to help listeners understand how coils absorb energy even in freezing temperatures. John also talks about the role of inverter compressors in matching indoor heating needs and how newer models improve low-temperature performance. He highlights the importance of base pan
