Fremont housing and HVAC
Most homes have gas forced-air furnaces, and many have central AC added later. Two-story homes in Mission San Jose and Ardenwood often have attic ducts and hot upstairs rooms. Warm Springs and Irvington homes from the 1950s and 1960s are single-story ranches with ducts in crawl spaces, and newer townhomes near the BART stations use heat pumps.
