It gets below 70F in my room if I do not have the A/C on. I normally turn the A/C on to about 80F before I go to bed. I'm not sure how else I can make the room warm. It also gets below 70F in the TV room where my Kingsnake is housed, so I'm afraid he'll get another RI. And since it gets cold in that room, the Beardie's tank gets colder inside because of the glass, so that is why she sleeps in my room on my long pillow that is against the wall. I think the A/C will also give my Hognose a draft since the tank is parallel from the vent, so that's another RI. I checked all of the Ball pythons' mouths and I don't see any signs of an RI, so they are fine for now. I'm still very worried, so I'm not sure what else to do. Any suggestions?
