A merchandiser including a case that has an air inlet and defines a product display area with a customer access opening. The merchandiser also includes a canopy that has a first air outlet and a second air outlet, a first passageway connecting the air inlet with the first air outlet to direct a first airflow through the first air outlet at least partially across the opening to define a primary air curtain, and a second passageway in fluid communication with a HVAC system by ducting coupled between the merchandiser and the HVAC system to direct a second airflow defining a secondary air curtain from the HVAC system through the second air outlet at least partially across the opening. The primary and secondary air curtains cooperate with each other to minimize infiltration of ambient air into the product display area.
