An inlet subassembly for a heating, ventilation, and air conditioning (HVAC) system. The inlet subassembly includes a fresh air inlet and a fresh air door movable to control fresh airflow through the fresh air inlet. The inlet subassembly further includes a recirculation air inlet and a partition defining a first airflow channel and a second airflow channel extending from the recirculation air inlet. A recirculation air door is adjacent to the recirculation air inlet and is movable to a closed position restricting recirculated airflow into both the first airflow channel and the second airflow channel, an open position permitting recirculated airflow into both the first airflow channel and the second airflow channel, and a two-layer position in which the recirculation air door restricts recirculated airflow into the first airflow channel and permits recirculated airflow into the second airflow channel.
