A modular air conditioning system comprises a self--contained refrigeration power cell, a heat exchanger, and a low pressure refrigerant communication circuit operably coupling the refrigeration power cell to the heat exchanger. The refrigeration power cell comprises a compressor, a condenser, an expansion device, and an evaporator which are serially coupled to form a high pressure closed refrigeration circuit. The low pressure refrigerant communication circuit thermally interfaces with the condenser to remove heat from the high pressure closed refrigerant circuit. Alternatively, a first circuit thermally interfaces with the evaporator to remove heat from the low pressure refrigerant. A first heat exchanger is adapted to mount in the cabin of an over-the-road or off-road vehicle. Preferably, a second heat exchanger and a second low pressure refrigerant communication circuit is included.
