Abstract: A heating, ventilation, and air conditioning (HVAC) system includes a condensate drain pan configured to be positioned beneath a heat exchanger of the HVAC system, relative to gravity, and configured to collect condensate formed via operation of the heat exchanger. The condensate drain pan comprises a drain surface, a plurality of walls extending from the drain surface to form a receptacle configured to collect the condensate, and a drain outlet formed in a wall of the plurality of walls. The condensate drain pan further comprises an air dam comprising a plurality of baffles, wherein a baffle of the plurality of baffles extends from the wall of the plurality of walls. The air dam is configured to re-direct an air flow flowing within the condensate drain pan away from the drain outlet.
