In this episode of the HVAC School podcast, host Bryan and guest Jesse Stewart from NAVAC discuss the generational divide in the HVAC industry and the importance of embracing new technologies and processes. They explore the challenges faced by both experienced technicians who may be set in their ways and newcomers to the trade who need proper mentoring. Jesse emphasizes the importance of respecting traditional methods while making way for new techniques. He discusses how bad habits can be passed down from mentors to apprentices, highlighting the need for continuous learning and adaptation in the rapidly evolving HVAC industry. The conversation touches on the importance of treating apprentices with respect and providing them with educational experiences rather than just menial tasks. The podcast delves into specific HVAC practices, particularly focusing on evacuation and recovery processes. Jesse explains the significance of using proper tools and techniques, such as valve core removal tools, high-quality vacuum pump oil, and appropriate hoses for different tasks. He debunks common misconceptions about hose sizes and manifold use, providing practical analogies to help listeners understand these concepts.
