In this episode of The Build Show, Jordan Smith breaks down the mechanical systems behind an affordable high-performance home. As the fourth and final installment in this series, Jordan explains why there is no single “right” HVAC or water-heating solution—and why proper design, modeling, and installation matter far more than brand names. He walks viewers through the importance of investing in a Manual J, S, and D before construction begins, outlines best practices for heat pumps, ERVs, and heat pump water heaters, and discusses smart recirculation strategies for comfort and efficiency. Jordan also touches on emerging battery and solar solutions, emphasizing the value of modeling performance upfront and commissioning systems at the end to ensure real-world results that match the design intent.
