San Francisco's proximity to the Pacific Ocean and Bay creates corrosion conditions that inland cities never experience. Salt-laden fog attacks metal vent pipes, creating pinhole leaks that allow CO to escape into attics and wall cavities. The Marine Layer's persistent moisture accelerates rust inside heat exchangers, compromising structural integrity years before visible exterior corrosion appears. Your furnace may look fine from outside while the heat exchanger has stress cracks leaking CO into your air supply. This climate factor makes professional CO leak inspection more critical in San Francisco than in dry inland locations. Coastal homeowners need more frequent testing because their equipment degrades faster.
