Postwar houses and Eichlers

Much of Castro Valley's housing went up during that postwar boom. In the Greenridge neighborhood, Joseph Eichler built roughly 200 homes in the early to mid 1960s. Eichlers have concrete slab floors with radiant heat built in and flat or low-sloped roofs, which leaves little room for ducts. Cooling one usually means ductless heads or a carefully routed duct system.
