$Advanced Refrigerant Recovery: Best Practices for Diverse Systems and Environments In this live episode of the HVAC School podcast, host Bryan Orr sits down with Jim Bergmann (MeasureQuick), Jesse Stewart, and Zane Stewart for an conversation on Advanced Refrigerant Recovery. The crew covers Best Practices for Diverse Systems and Environments and pushes into more advanced territory that separates a fast, clean recovery from a frustrating, stalled-out one. Topics include vapor vs. liquid recovery, when to switch to a push-pull method, why core depressors and hose sizing are the biggest overlooked bottlenecks, and how to properly evacuate and prep a recovery cylinder before you start. The panel also digs into recovery cylinder valve quirks, protecting your machine with a dryer, checking for moisture and fractionation before reusing refrigerant, and the surprisingly diverse environments techs actually work in — from residential splits to centrifugal chillers with hundreds of pounds of charge. The group wraps with a candid, sometimes heated discussion on cold-weather recovery, EPA-required levels, and why a system can still be holding a heck ton of refrigerant even after youve pulled it down to zero. Whether youre brand new to the trade or youve been doing this for decades, these best practices apply across diverse systems and every environment youll encounter in the field.$
