If your "snake room" is staying 88* or above, I'd turn off their supplemental heat (of whatever kind you're using) for sure.
Over heating a snake can make them cranky, sure, but can also cause neurological damage (permanently) or even death.
If nothing else, put a big closed container (like a capped plastic jug- for safety in case your snake knocks it over) of cold water in the cage to bring down the temps.
