All of your comments explain why the people at my husband's new job insist we come for a visit first before moving (even though we can't visit until a couple weeks before the move, which seems like a wasted trip to me). They said some people decline the job after experiencing the heat and want to make sure we can take the heat before we move.

I know everything's well air-conditioned, but what happens in the event of a power failure? Mass heatstrokes?
