A heating, ventilation, and air-conditioning (HVAC) system 10 includes a blower 16, a fresh-air valve 24, a bypass duct 32, and a bypass valve 34. The fresh-air valve 24 is operable to provide a mixture of air drawn from an outside-air duct 26 and a recirculated-air duct 28 to the inlet 18 of the blower 16. The fresh-air valve 24 is operable to a recirculate position 30. The bypass duct 32 is configured to couple the outlet 20 of the blower to the outside-air duct 26. The bypass valve 34 is located in the bypass duct 32. The cabin 12 is ventilated when the fresh-air valve is in the recirculate position 30, the bypass valve 34 is in the open position, and the blower is operated to blow air 22 out of the outside-air duct 26.
