This compact motor vehicle passenger compartment air conditioning system fits on the vehicle floor inside the motor vehicle. This mounting design avoids outside air conditioner mounting problems for vans and campers. The three-in-one motor vehicle air conditioning system achieves its space saving characteristics primarily by the use of a single coil having three separate compartments. One compartment cools by means of tapping into the vehicle's engine air conditioner. A second compartment heats by means of tapping into the vehicle's engine coolant system. A third compartment cools by means of an integral A.C. powered compressor. A primary circulation fan is powered either by D.C. or A.C. sources. A secondary exhaust fan is powered by an A.C. source. Outside air does not mix with passenger compartment air in any modes. Five modes of operation are possible with an optional onboard A.C. generator. The modes are on-the-road heating, off-the road heating, on-the-road air conditioning without using any A.C. generator, off-the road air conditioning, and on-the-road air conditioning with the use of an onboard A.C. generator.
