I've lived in California for almost 40 years. The house I grew up in south San Jose had a small, in-wall air conditioner because it was needed about 5 weeks out of the year. It's true most houses on the peninsula didn't have air conditioners originally, but many of them do now (probably more affordability than climate change).
