A spray nozzle or other dispensing opening is configured to deliver an aroma enhancement fluid onto an evaporator core of the HVAC system of an automobile. A fluid reservoir is configured to house the aroma enhancement fluid. Tubing can provide a flow path from the fluid reservoir to the spray nozzle. A pump unit can be located along the flow path to pump fluid from the fluid reservoir to the spray nozzle. A controller intermittently actuates the pump unit, thereby spraying the aroma enhancement fluid onto the evaporator core through the spray nozzles. In an associated method the user can select from one of a plurality of available aroma enhancing fluids. The aroma enhancement fluid can include an antibacterial component, an anti-fungal component, a deodorizer component, a fragrance component, and combinations thereof.
