A Conversation with NAVAC at AHR 2025

In this engaging episode of the HVAC School Podcast, host Bryan sits down with Jesse from NAVAC to dive deep into the evolving landscape of refrigeration technology, focusing primarily on the transition to A2L refrigerants. The conversation offers a refreshingly pragmatic approach to addressing industry concerns about these new, mildly flammable refrigerants, dispelling myths and providing practical insights for HVAC technicians.

The discussion begins by addressing the most pressing question for many technicians: Do you need to buy all new tools to work with A2L refrigerants? Jesse from NAVAC provides a nuanced response, emphasizing that while there are currently no regulations mandating new equipment, the company has proactively developed tools that are safety-certified and compatible with the new refrigerant types. They explore the intricacies of safety certifications like UL and CSA, explaining the differences between UL Listed and UL Verified, and highlighting the importance of intrinsically safe equipment, especially for tools like vacuum pumps and recovery machines.

NAVAC's approach goes beyond mere product promotion, with Jesse positioning himself as an educator first. The podcast delves into the technical details of A2L refrigerants, challenging common misconceptions and providing context about their flammability. Bryan and Jesse draw parallels with previous refrigerant transitions, noting how technicians were initially skeptical about R-410A but eventually adapted. They emphasize the importance of best practices, proper training, and understanding the actual risks associated with these new refrigerants, rather than succumbing to fear-based narratives.

The episode also showcases NAVAC's latest technological innovations, including smart probes, a Bluetooth scale, a smart valve for charging and recovery, and an advanced vacuum pump with a one-touch oil testing feature. These tools represent the company's commitment to improving technician efficiency and safety, with features that address real-world challenges faced by HVAC professionals.
