The Build Show Podcast

In this episode of the Build Show Podcast, Matt Risinger sits down with Jordan Smith to work through the full spectrum of residential HVAC mechanical systems — from the bare minimum to the over-engineered. The conversation moves quickly from what not to do (single-stage compressors with flex duct in unconditioned attics) to what actually performs: separate air handlers per floor, dedicated dehumidification, and ERV systems for continuous fresh air. For two-story homes, both agree that zone dampers are a dead end and that two independent systems are the only real solution. The middle-ground sweet spot they land on is dual single-stage units paired with at least one dehumidifier and a basic fresh-air intake strategy. A recurring theme is that equipment brand matters far less than installer quality — a well-installed Goodman beats a poorly installed premium unit every time.

Matt Risinger welcomes Kristof Irwin of Positive Energy for a deep discussion on the relationship between HVAC design, moisture management, and high-performance construction. Irwin explains how modern homes require a systems-based approach, where airtight enclosures, ventilation, and properly sized mechanical equipment all work together to improve comfort and indoor air quality. The conversation also covers humidity control, energy modeling, and the growing need for testing and verification as building standards evolve. Matt and Kristof discuss how builders, architects, and HVAC professionals coordinate early in the design phase to avoid performance issues later in construction.

Matt Risinger sits down with Kristof Irwin of Positive Energy to discuss how mechanical systems, enclosure design, and building science work together in high-performance homes. Irwin explains how HVAC design impacts comfort, humidity control, indoor air quality, and long-term durability, especially in challenging climates. The conversation explores right-sizing equipment, balancing ventilation with airtight construction, and using data-driven testing to verify performance. They also touch on homeowner expectations, evolving energy standards, and the importance of integrating architects, builders, and mechanical designers early in the process.

Matt Risinger talks with Jason Todd of TimberHP about the growing role of wood fiber insulation in high-performance construction. Todd explains how wood-based insulation products fit into modern wall assemblies, offering vapor-open performance, thermal control, and compatibility with airtight building strategies. The discussion covers manufacturing, supply chain challenges, and how these materials compare to foam and mineral wool in durability and environmental impact. They also touch on prefabrication, evolving building codes, and the shift toward low-carbon materials in residential construction.

Matt Risinger sits down with Bill Graber and Steve Rogers of The Energy Conservatory to explore how diagnostic testing informs high-performance construction. The conversation centers on blower door testing, pressure mapping, and airflow measurement as tools to verify airtightness and identify leakage pathways. They discuss how builders and energy raters use data to refine building enclosures, improve indoor air quality, and coordinate HVAC system performance. The group also touches on evolving codes, training, and the growing expectation for measurable results in residential construction.
