Eh, some of these 'prefer' judgements are iffy, especially on heat. Dallas, for instance, requires landlords provide heaters that keep a room at no less than 68 degrees F. Nearby Arlington requires landlords provide heaters that can maintain 70 degrees F. This regulation doesn't apply to those that own their own home, but the fact that the regulation exists at all seems to suggest that considering heating as a mere 'preference' is off-base.
