American Standard · Dual fuel, 2-zone
Dual fuel system in Oakland: the old furnace was replaced with a new American Standard S8X2B080M4 furnace, and an American Standard 5HPL5048A heat pump was added. The heat pump handles mild-weather heating and cooling, the gas furnace takes over on the coldest days — efficient comfort year-round. The home was also converted to a 2-zone system for better comfort room to room. Completed November 4, 2026.
