HVAC Basics

In today's episode of the Build Show Bryan Uhler tours a tight “mechanical room” in a conditioned attic and breaks down how HVAC and ventilation pieces fit together. He walks through a ducted VRF indoor unit, explaining supply and return plenums, refrigerant lines, thermostat wiring, and gravity-drained condensate management. Travis then highlights a Panasonic ERV and shows how fresh, filtered outdoor air can be introduced through the return side to reduce added ductwork while maintaining performance. Along the way, he emphasizes code-required access, proper platform layout, lighting for serviceability, and coordination between mechanical and electrical trades. Perfect for builders who want to recognize components faster and deliver better homes overall.
