Oh no, snakey puke!
Even though I'm new to corn keeping myself, a good idea would be to buy/make (even cardboard box would work) another hide, and to keep one on the cool side and the other on the warm side, just so your snake has the option if it wants to feel secure on either side it chooses, as well as to thermoregulate and adequately digest its meals.
Do you know what the ambient air temp. is in your house, more specifically the room your shnake is kept in?
Another good idea is to go get a digital thermometer with a probe; you can even get them for like seven or eight bucks from Wal Mart, and those work just fine.
Good luck on your shnakey!
