The present teachings include a heating, ventilation, and air conditioning (HVAC) unit including an evaporator, a heater core, and an airflow control door. The heater core is arranged downstream of the evaporator with respect to a direction of airflow through the HVAC unit. The airflow control door is downstream of both the evaporator and the heater core. The airflow control door is movable to increase and decrease a cross-sectional area of an airflow path downstream of the temperature control door, such as to facilitate mixing of airflow that has passed through the heater core with airflow that has passed around the heater core.
