I don't know much about snakes, a fellow chef of mine back when kept a BP. We would talk pets every so often. What I picked up was that if they start to pale and grey in they eyes, they should not be fed. They tolerate household conditions well, but A/C isn't going to do them the best. He opted for lamp warming, he didn't feel inter tank mats and controllers were in his budget, but I know he had that snake for over half a decade. We lost contact over the last few years, but if you can't find answers here or via Google, I would be happy to mail him with any questions you have.
I remember him specifying his snake female, it could be man/woman thing??
