A package terminal air conditioning unit that is split into two sections, an indoor section and an outdoor section. The components of the indoor section are housed in an indoor cabinet of all molded construction having a recirculating air duct that is contoured to conduct air quietly and efficiently through the cabinet. Interchangeable guide vanes are also mounted in the air duct to act in conjunction with a crossflow fan rotor which permits the cabinet to be adapted to accommodate fans of different sizes and shapes without having to alter the configuration of the molded cabinet. The outdoor section simply contains a heat exchanger and a small blower which are housed in a lightweight cabinet. The outdoor cabinet used in one preferred embodiment of the invention is hung on the outside wall of a building and the outdoor heat exchanger is connected to the remaining air conditioning components housed in the indoor cabinet by two refrigerant lines.
