A three-member molded plastic housing for rooftop air conditioners, including base and intermediate members having molded portions which together provide component lower and upper compartment walls and blower scrolls. The third member, an outer shroud, abuts sealedly along a roof ridge of the intermediate member to prevent recirculation within the shroud of condenser blower outlet air. The base member has downwardly molded projections for facilitating positioning the unit over a roof opening and resisting sideward forces.
