An inlet subassembly for a heating, ventilation, and air conditioning (HVAC) system. The inlet subassembly includes a divider defining a first airflow path and a second airflow path on opposite sides of the divider. The first airflow path extends from a first side of the recirculation air inlet and a first side of the fresh air inlet. The second airflow path extends from a second side of the recirculation air inlet and a second side of the fresh air inlet. A first inlet door is movable to control airflow into the first airflow path from the first side of the recirculation air inlet or the first side of the fresh air inlet. A second inlet door is movable to control airflow into the second airflow path from the second side of the recirculation air inlet or the second side of the fresh air inlet.
