Adam Mufich and Casey Contreras talk with Jeff Sturgeon about economizers, digging into installation challenges, the health and cognitive benefits of proper ventilation, and how saved data reveals real system performance.

In this episode, Adam Mufich and Casey Contreras interview Chris Hughes (The Energy Conservatory) and Roman Baugh (HVAC School) about cold-climate heat pumps and VRV systems. From charging to system-specific service tips, we break down what contractors need to get right in the field.

David Richardson and Adam Mufich sit down with Todd Titus from HARDI to break down ultra-low GWP refrigerants, upcoming regulations, and the real-world trickle-down effects on contractors and consumers. We also dig into how HARDI is pushing back and advocating for the HVAC industry.

Jim Davis takes us through the real-world experiences that led him to uncover what actually affects combustion efficiency. Along the way, he challenges common trade myths and simplifies the basics of heat transfer, showing how they play a critical role in combustion.

Not all duct leakage is created equal. Steve Rogers from The Energy Conservatory explains the critical differences between leakage inside and outside the thermal envelope and how each affects comfort, efficiency, and performance. He also dives into diagnostic testing strategies that help uncover the real sources of airflow and comfort issues.

Tony Amadio is the President of First Dimension Software and the developer of TrueLoads, a residential HVAC system design application. He brings more than 18 years of engineering experience in the HVACR industry, along with a strong background in HVAC education. Tony holds a Master of Science in Mechanical and Aerospace Engineering from the University of Central Florida.

In this episode, Tony compares different methods of load calculations. He also talks about the importance of accuracy and what makes heat balance different.
