1. A heat pump system, comprising:
a refrigerant circuit comprising a compressor, a reversing valve, a first heat exchanger, a second heat exchanger, a reheat heat exchanger, a first three-way valve, and a second three-way valve,
wherein the reversing valve is configured to receive refrigerant from the compressor and adjust between a first configuration to direct the refrigerant toward the first three-way valve and a second configuration to direct the refrigerant toward the first heat exchanger,
wherein the first three-way valve is configured to adjust between a first position to direct the refrigerant between the reversing valve and the second heat exchanger and a second position to direct the refrigerant from the reversing valve to the reheat heat exchanger, and
wherein the second three-way valve is configured to adjust between a third position to direct the refrigerant between the first heat exchanger and the second heat exchanger and a fourth position to block flow of the refrigerant between the first heat exchanger and the second heat exchanger.
