Matt Risinger centers the conversation on blower door testing with Building Scientist Sam Myers from RetroTec, exploring how it functions as a practical tool for measuring and improving air tightness in residential construction. Myers outlines design choices that influence results, including keeping mechanical systems inside the conditioned envelope and minimizing major air leakage pathways. The discussion covers blower door equipment, typical costs, and training options, while emphasizing the value of builders owning and operating their own systems. Risinger frames testing as a hands-on method to diagnose air leakage, compare performance across projects, and refine construction practices in real time.
