A bus air conditioning unit suitable for roof mounting on either end of a bus, including a metallic frame which includes a condenser and a control panel as integral structural members. A removable cover reveals all components of the unit which are not mounted outside the frame, which components include two condenser fans and two evaporator blowers mounted on a common axis, permitting a single double ended electric motor to drive them. The condenser fans are selected to draw outside air through a condenser, and then exhaust the air out the axial ends of the unit, when the unit is front mounted, and they are selected to draw outside air into the axial ends and exhaust it through the condenser, when the unit is rear mounted.
