A vehicle heating and cooling system includes a compressor(s) for compressing a fluid in a cycle including at least two compressions, and a control module for controlling the compressor dependent upon an ambient condition. The module controls a power of the compressor by adjusting a motor speed driving the compressor and/or a pressure drop of the fluid moving through expansion devices. The pressure drop is controlled by changing a size of an opening in the expansion devices. A related method includes compressing a fluid in a first and a second compression cycle, determining an ambient temperature, sensing a temperature of the fluid outlet from a first heat exchanger, sensing a temperature and a pressure of the fluid outlet from a second heat exchanger, calculating a desired power of the compressor based thereon, and adjusting a parameter of the compressor dependent upon the calculated desired power of the compressor.
