There won't be a climate where you can live without AC in the next 20 years.

Anything south of upstate NY is already pretty unbearable in the summer. Another added benefit of AC is the dehumidification of your interior, which means less mold.



Even in the desert humans have been able to keep their dwellings cool with passive cooling long before we had ACs or even electricity.

Take a look at windcatchers. Even better if you combine them with a quanat. Lots of stuff like this we don't use anymore.
