Ya we had "no A/C" for two days last week, not by choice, it broke and our house hit 89 degrees inside, even with the windows open and fans blowing. I have to turn off all the lights on my cages and vent the doors, and wire up some small fans to cool everything down, killed my humidity, but at least we all survived. A/C is fixed and the house is nice and cool again.... Gotta love SoCal "seasons" haha.
