Black Diamond, Washington · Residential Project
This is a homeowner-managed residential project involving the conversion of a portion of an attached garage into conditioned mechanical/shop space and a complete HVAC system redesign and replacement for a two-story home.
The goal is a high-efficiency, properly sized dual-fuel system with balanced ventilation and all ductwork located inside conditioned space.
The project is targeting a dual-fuel configuration with a modern heat pump (approximately 2.5-ton class) paired with an 80k BTU high-efficiency gas furnace backup. Balance point and Manual S compliance are active design considerations.
This public page is intended to give interested installers and suppliers a clear understanding of the project scale, goals, and technical direction.
Once a vendor is selected, full access to progress photos, floor plans, Manual J reports, equipment cut sheets, and related documentation will be provided through a private shared folder.
