The present invention relates to a temperature control system for heating and cooling a passenger compartment of a vehicle during start up of an engine of the vehicle. The system comprises a working fluid conduit configured to convey a working fluid and being in thermal communication with a heat source or a heat sink. The system further comprises a heater core (230) disposed in an air channel of the vehicle and in thermal communication with a power train coolant in thermal communication with the engine, and a thermoelectric device (240) having a main surface and a waste surface, wherein the waste surface is in thermal communication with the working fluid conduit. Additionally, the system comprises a heat exchanger (250) disposed in the air channel and in thermal communication with the main surface of the thermoelectric device (240), wherein the thermoelectric device (240) is operatively connected to the air channel downstream from the heater core (230) when air flows (210) through the air channel. The system also comprises a controller configured to operate the temperature control system in two or more modes of operation. The two or more modes of operation comprise a start up heating mode, when the engine is started from a cold state, wherein the thermoelectric device (240) is configured to heat the airflow (210). There is also a steady state heating mode, when the engine is ready to heat the airflow (210), wherein the engine is configured to heat the airflow (210) via the heater core (230) while the thermoelectric device is disengaged.
