Hvac Know It All Podcast

In this episode of the HVAC Know It All Podcast, host Gary McCreadie talks with Eric Ruggles, Director of Engineering at Ritchie Engineering Co., Inc. (YELLOW JACKET), about airflow, static pressure, and modern diagnostic tools. In Part 2, they discuss proper system commissioning, checking pressure across components, and identifying airflow restrictions without disassembling equipment. Eric explains how tools like a digital manometer and wireless probes help measure system performance, airflow, and gas pressure. They also cover the shift from manifolds to probes, including concerns about refrigerant loss and system contamination. The conversation wraps up with practical insights on using airflow, temperature, and CFM measurements to determine true system capacity and improve service decisions. Gary and Eric discuss airflow testing, static pressure, and how modern tools improve system diagnostics and performance. They explain how proper commissioning sets baseline readings and helps identify issues like plugge
