Cooling in the summer

How warm can you let it get for the snakes in the summer?

Is it detrimental for ambient to be up to 85-90 deg.?

Our AC doesn't work as well as it should and on occasion, the animal room can get up to 90+ when the AC decides not to work. While it was causing issues with my other animals, the snakes didn't seem to care. I simple lowered the thermostat a bit and they were fine. Once the heat subsided, a turned it back up. As long as the temp doesn't get above 95, you should not have an issue.
