Cheapest Good Mechanicals | Build Show Podcast Ep 218
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.
