A dual-integrated HVAC system for an automotive vehicle is provided that includes a housing, a front HVAC unit with a front blower, and rear HVAC unit with a rear blower whereby both the front and rear HVAC units are housed in the housing. The front blower generates an airflow through a front airflow path and the rear blower generates an airflow through a rear airflow path. A separating wall separates the front airflow path from the rear airflow path. The HVAC system further includes an evaporator with a first portion in the front airflow path, a second portion in the rear airflow path, and a seal situated between the first portion and the second portion.
