Well I am no where near Arizona but this happened to me this year. I have 5 geckos and at the time I had 3 eggs incubating so it was scary. The room got up to 83 degrees, and the eggs got up to 78 degrees. We got the A/C replaced within a couple of days but if it would've lasted any longer they would've gone to the basement where it is about 10 degrees cooler.
