Furnace Replacement in San Francisco

San Francisco's fog and damp, cool nights mean heat is needed for much of the year, not just in winter. Many homes in the Sunset, Richmond and Mission districts still run furnaces installed decades ago, often in tight basements, garages or closets. As these systems age, the signs add up: rooms that never get warm, a furnace that short-cycles, repeated igniter or control board failures, rising gas bills, rust on the cabinet, and a growing worry about the heat exchanger and venting.
