HVAC Design: Understanding Proper Ductwork Design & the Importance of Manual D & T with Alex Meaney

Описание: Have you ever thought about how duct design and grille placement impact your comfort?

Manuals D and T are the playbooks that ensure air flows efficiently and evenly throughout your home. In Part B of this two-part class, Alex Meaney explains how Manual D helps your ducts get sized and laid out correctly, while Manual T fine-tunes the details of registers and grilles so air gets where it needs to go. You’ll learn how poor duct design can undermine even the best HVAC system, plus smart ways to improve existing ducts, choose the right contractor, and spot sales-driven red flags.

If you're ready to build an HVAC system that runs efficiently without wasting energy or causing new problems, this class is for you. If you missed Part A on Manuals J and S, be sure to catch it first for the full picture.
