Average temperatures were also lower in 1970 and we didn't put as many of the jobs in places where you absolutely needed an AC.

What's average income less average house price? Has that gone up or down?

Yes, but not enough to change whether you want AC or not: https://www.extremeweatherwatch.com/cities/washington-dc/yea.... In DC in 1970 you had 98 days above 85 degrees. The year before was 80 and the year after was 71. Last year was 72 and the year before was 93. There are more warm days, but you wanted an AC in the DC area back in the 1970s too.

I don’t think that’s true. The south and mid atlantic was always a huge share of the population. And the midwest was a bigger share than today, while the temperate west coast was a smaller share. You need AC in Chicago too: https://www.extremeweatherwatch.com/cities/chicago/yearly-da.... Even in the 1970s in Chicago you had 30-60 days over 85 every year.
