Have you taken temperature measurements on the floor near the north wall? The floor is always colder than the rest of the room.

I have my brumating snakes in my bedroom on the floor in tubs wrapped in quilts. Even when I heat the cabin up during the day the temperatures in the tubs stay in the mid 40's to low 50's. Some of my snakes are montane species which do better at low temps. The quilts hold the temps stable, and if it gets too cold I just open the quilts a bit and let ambient air in. I am in the Sierra Nevada foothills, so getting things cold enough is not a problem! LOL! I use indoor outdoor thermometers to read the conditions; put the outdoor probe in with the snakes and the indoor part on top of the tub so you can read it without having to disturb anything.



If getting the temps down is just not happening for you try putting frozen gel packs wrapped in a towel in the tubs. Don't forget to wrap the tubs in some sort if insulation, or they will wind up at the ambient temperature of the room rather quickly.
