Yes. An appropriately designed ERV can operate in both heating and cooling seasons.
During winter, it can recover heat from exhaust air to precondition incoming cold air. During summer, it can transfer heat away from incoming hot air and, with an enthalpy core, exchange moisture as well.
Performance varies with outdoor and indoor conditions, airflow, exchanger characteristics, and the selected operating mode.
