In this episode of the HVAC Know It All Podcast, host Gary McCreadie continues his discussion with John Ellis, a Product Ambassador at Dust Free, LP, an Instructor at Amana/Goodman/Dakin, and a Field Service Trainer at The New Flat Rate, Inc, on air quality, system design, and the role of UV lights in HVAC systems. In Part 02 of their talk, Gary and John explore the importance of air mixing, static pressure, and system performance. They break down how proper air distribution and good filtration can improve efficiency and comfort. They also dive into UV lamp use and its effectiveness in residential applications, offering practical insights for technicians on balancing technology with system design.

John and Gary discuss the importance of air mixing in HVAC systems and how it affects air quality and comfort. They explain how poor air circulation can lead to stagnant pockets of air, causing pollutants to build up. John shares how using ceiling fans or proper system design can help improve air movement. They also talk about the impact of static pressure on airflow and how to balance it when designing systems. Finally, John gives his thoughts on UV lamps in HVAC systems, explaining why they can be useful but may not always be the best solution.

This episode is packed with practical HVAC tips, air quality insights, and expert advice on system design. It helps techs understand the importance of air mixing, managing static pressure, and improving airflow. John and Gary also share their thoughts on UV lamps and how they can be useful in certain situations. This episode is all about using the right techniques to improve system efficiency and comfort while making informed decisions.
