1. A method for providing heating or cooling to a plurality of zones in a conditioned space, comprising:
adjusting a temperature of a primary airflow using a heating, ventilation, air conditioning, and refrigeration (HVACR) system including a heat pump circuit, the heat pump circuit including a compressor;
after adjusting the temperature of the primary airflow, distributing the primary airflow to a plurality of terminals, each of the plurality of zones being associated with at least one of the plurality of terminals;
directing heat from the heat pump circuit to at least one of the plurality of terminals; and
heating air at the at least one of the plurality of terminals using the heat directed from the heat pump circuit,
wherein directing heat from the heat pump circuit to the at least one of the plurality of terminals includes directing hot working fluid from the heat pump circuit to the at least one of the plurality of terminals, wherein the hot working fluid includes a refrigerant of the heat pump circuit.
