Systems and methods for operating a heater for a passenger cabin of a vehicle. In one example, fan speed of an evaporator cooling fan is adjusted to improve heating efficiency. In particular, fan speed is incrementally increased and maintained at the higher speed if output power of a compressor is reduced by more than an amount of power used to incrementally increase the fan speed.
