Airborne contaminant detection and localization systems (200) include an HVAC system (102) having a duct (202), a first vent (204a) connected to a first indoor space (208a), and a second vent (204b) fluidly connected to a second indoor space (208b), with the second vent (208b) being downstream from the first vent (208a) in a flow direction (210) along the duct (202). A monitoring system (212) includes a first (216a) and second (216b) sensor elements arranged proximate the first (204a) and second (204b) vents, respectively, the sensor elements (216) configured to detect one or more airborne contaminants. A central unit (214) receives sensor data from the sensor elements (216). The central unit (214) includes information regarding a location of each of the sensor elements (216) within the duct (202). The central unit (214) determines the presence and intensity of an airborne contaminant in the duct (202) from the sensor data and establishes a detection zone (220) that includes a portion of the duct (202) having a highest detected intensity of the airborne contaminant.
