Well, sure. There are lots of places in the US (and elsewhere) where you don't really need AC. It helps to have good ventilation, maybe some fans, and possibly other passive cooling. Maybe just deal with a week or two of uncomfortably hot weather during the summer.

Of course, it also helps to live in a house that is out in the country or at least suburbs rather than a city apartment. A window AC unit or two also can help for things like cooling a bedroom for the hottest nights.
