When Farwa Ali and her family wanted to buy a bigger home, Mountain House, Calif., seemed to check all of their boxes.

It seemed to be a perfect match — at least until their first summer, when the scorching temperatures of California’s Central Valley set in. “We never had an idea that it would be this hot,” Ms. Ali said on Tuesday as she darted through a grocery store parking lot where the temperature was well over 100 degrees.
