A heating and cooling system includes a compressor for pumping a heat medium through a tubing device, a primary heat exchanger coupled to the compressor, a control device coupled to the primary heat exchanger and coupled to a intermediate heat exchanger to control the intermediate heat exchanger either to dissipate heat or to absorb heat. Another control device is coupled to the intermediate heat exchanger and coupled to the compressor and a secondary heat exchanger, to control the heat medium from the intermediate heat exchanger either to flow through the secondary heat exchanger or to directly flow into the compressor without flowing through the secondary heat exchanger.
