There's definitely none on the new Enviro's or B9TL's as there's an aircon unit at the top of the stairs when it's fitted - http://www.britishmodelbuses.com/Real_bu..._Large.jpg
Well during the summer the StreetDecks managed to blow out very cold air, whether or not they actually have AC I don't know, but whatever they had worked, and whatever the B5s have didn't!
