Good QC, Startup, and Punchout Processes

byBryan Orr

In this episode, Bryan is joined by guests Jacob and JD to discuss quality control (QC), punch out procedures, and best practices in HVAC installation and service. The conversation delves deep into the various aspects of maintaining high standards in workmanship, from aesthetic considerations to technical performance metrics that affect system longevity.

The discussion begins with an exploration of workmanship quality and how to instill pride in work among team members. The guests share insights about the importance of company culture in maintaining high standards, emphasizing that quality control isn’t just about catching mistakes but about fostering an environment where everyone takes ownership of their work. They discuss how photo documentation can be a powerful tool for quality control, allowing team members to review work remotely and catch issues that might be missed in the field.

The conversation then shifts to the more technical aspects of quality control, particularly focusing on procedures that affect system longevity but might not be immediately visible to clients. This includes proper brazing techniques, pulling adequate vacuums, and proper system charging. The guests emphasize the importance of having a culture where team members hold each other accountable for following proper procedures, even when cutting corners might be tempting. The episode concludes with a detailed discussion about working with inspectors and handling code compliance, offering practical advice for maintaining good relationships with authorities having jurisdiction (AHJ) while ensuring work meets all necessary standards.
