An air conditioning system for a vehicle includes an auxiliary compartment, and a secondary cooling circuit positioned within the auxiliary compartment. The secondary cooling circuit includes a radiator and an electric coolant pump assembly. An AC circuit includes an electric compressor assembly, a condenser, an evaporator, and an electric fan for blowing air through the evaporator. The compressor assembly and the condenser are each located within the auxiliary compartment. The condenser is configured as a refrigerant to coolant heat exchanger with a refrigerant flow path and a coolant flow path. The refrigerant flow path is in fluid communication with each of the compressor assembly and the evaporator, and the coolant flow path is in fluid communication with each of the coolant pump assembly and the radiator. The AC circuit and the secondary cooling circuit may be mounted to a common sub-frame which is removably attached to a cab of the vehicle.
