Earth Advantage & BetterBuiltNW welcome HVAC contractors, builders, architects and other interested building professionals for this 1-hour on-demand training to learn about common ductwork installation performance issues that can be easily avoided.

Clients expect high-performance homes that meet their comfort, health, and energy-efficiency expectations, and well-designed and installed modern HVAC systems are vital to success. 

A well-performing system starts with a good design but that alone is not a guarantee. Proper duct installation significantly impacts the delivery comfort and energy efficiency. We'll cover topics that include:

  • Understand how to select and install various ducting materials and optimize performance, comfort, and energy efficiency. 
  • Hear about some of the more common problems of duct installation encountered in the field.
  • Discuss how to get the best performance from flex duct. 
  • Learn about the terms like Equivalent Length of Duct Fittings, Zonal Pressure Relief, the "2-foot" rule, and why it's crucial to comfort.  
This training discusses common duct installation challenges and is an excellent resource for entry-level installers as well as a great refresher for more seasoned technicians alike. We encourage high performance builders to share this training opportunity with their HVAC contractors.
