A battery powered auxiliary HVAC system designed to heat and cool at least a sleeper compartment of a vehicle such as a truck with a management system for conserving battery power. The management system includes a processor connected to temperature sensors, motion sensors, occupancy sensors, etc. for controlling a variable speed compressor, evaporator fan and condenser fan. A fuel fired heater is positioned between an evaporator coil in the inlet of an enclosure and the evaporator fan in an outlet of the enclosure such that air flow passes around the heater. The power electronics to operate the system may be actively cooled by connection tubing providing a heat sink between an evaporator outlet and a compressor inlet.
