In this episode of the HVAC Know It All Podcast, host Gary McCreadie wraps up his chat with Tyler Nelson from Sauermann Group. In Part 02 of their discussion on refrigerant leaks, sealants, and best practices in HVAC diagnostics. Diving deeper into controversial yet evolving topics, Gary and Tyler examine both the theory and field-tested realities of leak detection and system maintenance, shedding light on how technicians can balance practicality, ethics, and innovation in their everyday work.

Tyler and Gary talk about how leak sealants in HVAC systems are seen differently now, with some techs testing them and finding they work well in certain cases. They explain how formicary corrosion causes small leaks that are hard to fix fast, and why sealants can be a good short-term option. They also cover how to properly check for leaks using tools, bubbles, and even just your hands. Tyler shares details about a new leak detector from Sauermann that works on modern refrigerants and is easy for techs to use and afford.

This episode is full of real-world HVAC advice, smart leak detection tips, and honest talk about when and how to use sealants. It helps techs learn better ways to find leaks, choose the right tools, and keep systems running safely while saving time and money.
