An air treatment system for a vehicle includes a first compressor selectively coupled to a first power source of the vehicle. A second compressor is selectively coupled to a second power source of the vehicle. A first heat exchanger communicating with an interior space is defined in the vehicle. A second heat exchanger communicates with an environment exterior to the vehicle. A valve member is provided which, in a first position, couples an inlet of each of the first and second compressors to an outlet of the first heat exchanger and an outlet of each of the first and second compressors to an inlet of the second heat exchanger. In a second position, the valve member couples the outlets of the first and second compressors to an inlet of the first heat exchanger and the inlets of each of the first and second compressors to an outlet of the second heat exchanger. A controller is provided that selectively actuates at least one of the first and second compressors and the valve member.
