i can tell you from living in az, that if you do not turn your a/c on, it gets to over 90 degrees in your home in no time and it is not healthy. when it is over 100 degrees outside, you have to have a/c, not only for you but for your pets as well.
our power went out for four days one summer due to a storm. we stayed for two days and it got so bad we had to go somewhere with a/c. the kids were starting to feel the effects of the heat and people tend to get heatstroke in this weather as a result. you definitely need a/c.
if he is living north of phoenix about one hundred miles or so, no, he probably would not turn on the a/c hardly at all.
