A HVAC system for a vehicle that includes a propulsion system, a frame, a passenger compartment, and a door coupled to the frame. The HVAC system includes a refrigeration circuit that selectively controls the temperature of the passenger compartment based on a sensed temperature within the passenger compartment. The refrigeration circuit includes an exterior heat exchanger, a first air moving device coupled to the exterior heat exchanger, an interior heat exchanger, a second air moving device coupled to the interior heat exchanger, and a compressor. The HVAC system also includes a controller that is operable to detect a condition of the vehicle that includes at least one of a position of the door, a location of the vehicle, and a load of the propulsion system. The controller is programmed to adjust the refrigeration circuit in response to the sensed passenger compartment temperature and the detected vehicle condition.
