Original Problem

Homeowners struggle to design compliant HVAC systems that ventilate all rooms without expensive ductwork

Homeowners retrofitting or building homes need to ventilate bedrooms but lack clear guidance on using transfer air from mechanically supplied living spaces—a cheaper alternative to running separate ducts. Current solutions either require expensive full ductwork installation or leave homeowners uncertain about code compliance, energy efficiency, and whether their DIY approach will actually work. They're stuck between hiring expensive HVAC contractors or risking non-compliant installations.
