A compact air conditioner unit suitable for mounting on the roof of a bus. The unit has a frame which has a shallow height dimension for appearance and reduced drag, and a length dimension which enables the unit to be securely mounted between any two adjacent structural support struts of the vehicle. The air conditioner unit achieves compactness without loss of necessary evaporator and condenser coil surface area by splitting both the evaporator and condenser functions into two coils. Two evaporator coils are spaced laterally apart on the frame, and two condenser coils are nested between the spaced evaporator coils, such that midpoints of the condenser and evaporator coils lie in a common plane perpendicular to the sides of the vehicle. Condenser fans are mounted between the spaced condenser coils, and evaporator blowers are mounted outside each evaporator coil, between each evaporator coil and an adjacent side of the frame.
