How Improper Handling and Low Airflow Kill HVAC Compressors Without Warning with Glen Schwarzman

In this episode of the HVAC Know It All Podcast, host Gary McCreadie talks with Glen Schwarzman from Copeland about compressors and refrigerants. They discuss why using the wrong refrigerant can cause problems and void warranties. Glen explains different types of compressors, how variable speed tech works, and the importance of protecting compressors with things like phase monitors. They also cover tips for oil return in modulating compressors and why understanding new tech is key for HVAC techs. The episode is full of helpful info for anyone working with modern HVAC systems. Glen Schwarzman explains how using the right refrigerant and compressor protects HVAC systems and avoids costly failures. He breaks down the differences between single-stage, two-stage, and variable speed compressors and why electrical protection is important. Glen shares tips on oil return in modulating compressors and the role of vapor injection in heat pumps. He also stresses the need for techs to learn modern HVAC technology to better serve customers and avoid costly mistakes. Throughout the episode, Glen explains why using the correct refrigerant is crucial to avoid compressor damage and warranty issues. He walks through different compressor types, how variable speed technology works, and why electrical protections like phase monitors matter. Glen also shares tips on keeping oil flowing in modulating compressors and how vapor injection boosts heat pump performance. He encourages techs to embrace new HVAC tech and use resources like Copeland Mobile to stay informed. Expect to Learn: Why using the right refrigerant matters for compressors.
