Most South Bay housing is postwar 1940s–60s single-story stock, and original galvanized supply lines and cast-iron drains are reaching end of life. Marine-layer humidity and salt air near the beach cities corrode outdoor condenser coils and flue components faster than inland. The mild coastal climate means many older homes never had central air and are strong candidates for ductless retrofits.
