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.  Huge thanks to our episode sponsor,  JELD-WEN.
