Jim shares insights on decay testing, an often overlooked but crucial step in HVAC maintenance that enhances equipment longevity and minimizes maintenance issues.
Jim explains the process of performing a decay test using the BluVac App and a TruBlue vacuum hose, highlighting the importance of maintaining a decay rate below one micron per minute. He also demonstrates how to identify leaks and moisture using linear graph analysis, emphasizing the need for consistent testing, especially in cold climate heat pumps. The video underscores the significance of decay testing in improving system reliability and avoiding service calls in adverse weather conditions.
