A HVAC system 75 for a vehicle 10 that includes a propulsion system, a frame 15 and a door 35 coupled to the frame. The HVAC system includes a refrigeration circuit that selectively controls the temperature of the vehicle based on a sensed temperature within the vehicle. 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 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 temperature of the vehicle and the detected vehicle condition. The controller is programmed to decrease a speed of at least one of the first air moving device, the second air moving device, and the compressor in response to detection of a first condition of the vehicle and to increase the speed of at least one of the first air moving device, the second air moving device, and the compressor that was previously operated at a decreased speed in response to detection of a second condition of the vehicle. The first vehicle condition includes the location of the vehicle detected in close proximity with a freestanding structure, and the second vehicle condition includes the location of the vehicle detected at least a predetermined distance from the freestanding structure.
