Thermoelectric enhanced hybrid heat pump systems are provided herein. A compressor increases the pressure of refrigerant within tubing. A first heat exchanger is downstream of the compressor and changes enthalpy of first fluid flow through heat exchange with refrigerant. A second heat exchanger changes enthalpy of second fluid flow through heat exchange with refrigerant. A thermoelectric device is downstream of the first heat exchanger and reduces refrigerant temperature. Expansion valves are downstream of the thermoelectric device and first heat exchanger, respectively located on first and second sides of the thermoelectric device, and expand refrigerant and reduce refrigerant pressure while conserving refrigerant enthalpy. At least one valve reverses refrigerant flow within the tubing without changing compressor operation. A control system controls the thermoelectric device and at least one valve to switch the heat pump system from heating mode to cooling mode and from cooling mode to heating mode.
