Why Good HVAC Design Needs Verification | Venting with the Pros with Matthew Cooper

Send us Fan Mail (https://www.buzzsprout.com/2525743/fa...) What happens when a well-designed HVAC system reaches the jobsite—but the finished installation doesn’t perform as intended? In this episode of HVAC ADHD™ Vodcast’s Venting with the Pros, Jeremy Begley sits down with Matthew Cooper, Senior Vice President and Chief Operating Officer at PEG, to explore the gap between residential HVAC design and actual system performance. Matthew shares observations from PEG’s design, inspection, and testing work. Together, they discuss equipment oversizing, inconsistent design review, compact duct systems, return-air pathways, and the importance of verifying the completed installation. They also explore why variable-speed equipment cannot substitute for sound design—and how coordination among builders, designers, and installing contractors can help protect the investment in better HVAC equipment. In this episode, we discuss: • Manual J, Manual S, and Manual D—and the limits of default assumptions • Equipment over sizing and variable-speed performance • Compact duct layouts and interior high-wall supply registers • Ducted returns, jump ducts, and transfer grilles • Construction coordination and product availability • HVAC grading, commissioning data, and comfort complaints For builders, HVAC contractors, designers, and HERS raters, this conversation offers a practical look at connecting design intent with measured performance.
