Steve Baczek walks through the HVAC strategy on an active build, breaking down how the home is divided into distinct conditioning zones. The second floor runs off a ducted Bosch air source heat pump housed in an accessible mechanical closet, with a chase system distributing supply air across two bedroom suites and their bathrooms. The basement and first floor share a larger zoned system — a single unit handling both levels through dampered supply runs — while a separate wall-mounted heat pump covers a dedicated workshop space. Throughout, Steve points to the high-performance building enclosure as the reason oversized ductwork and perimeter heating aren't necessary.
