In this episode of the HVAC Know It All Podcast, host Gary McCreadie continues his conversations with Gord Cooke, President at Building Knowledge Canada, and Ian Walker, Sales & Marketing Manager at Aeroseal, about duct sealing and building performance. They explain how Aeroseal works by sealing leaks at the source without coating the entire duct, clearing up common misconceptions. The discussion highlights how leaky duct systems can lose a large amount of airflow, affecting comfort, balance, and system efficiency in a home. Gord shares insights on why sealing ducts improves airflow control and helps deliver air where it is needed most. They also talk about return air design, common issues with panned returns, and why proper airflow measurement matters for HVAC performance.

Gary, Ian, and Gord discuss how Aeroseal works to seal duct leaks using pressure and a targeted sealant that only sticks at gaps. They explain that the process does not coat the full duct system and instead seals leaks from the inside. The conversation covers how duct leakage can reduce airflow, comfort, and system balance in a home. They also talk about how sealing ducts can improve air delivery and make balancing systems more effective. Gord shares insights on return air design, explaining common issues with panned returns and why they often do not move much air. They finish by highlighting how proper sealing and airflow checks help improve overall HVAC performance and comfort.

Expect to Learn:

• How Aeroseal seals duct leaks by targeting gaps without coating the full duct system.

• How duct leakage can reduce airflow, comfort, and system balance in a home.

• How sealing ducts can improve air delivery and make system balancing more effective.

• Why return air systems often move less air than expected, especially when not fully ducted.
