But are they working with your air handler or quietly fighting it? In episode 535 of the Smart Buildings Academy Podcast, you step back from sequences and setpoints to look at VAV box control theory as a complete system. Because a VAV box is not just a damper and a reheat coil. It is a decision-making device balancing comfort, ventilation, and energy while the air handler tries to keep the entire building stable. When airflow, static pressure, supply air temperature, and ventilation minimums are not coordinated, you feel it in callbacks, energy bills, and unhappy occupants. This episode challenges you to think beyond individual points and start thinking system-wide. Topics Covered How VAV boxes and air handlers must coordinate to maintain stability Static pressure control and why reset strategies change everything Supply air temperature reset and its impact on airflow and reheat Ventilation minimums, occupancy, and indoor air quality control Reheat coordination and preventing simultaneous heating and cooling If you design, program, or troubleshoot VAV systems, this conversation will change how you approach your next project.
