A heating, ventilation, and air conditioning (HVAC) system may comprise an evaporator core including an upstream inlet face in which humid air is received, a downstream outlet face from which dehumidified air is discharged, and a plurality of air-contacting surfaces extending between the inlet and outlet faces. In one form, an antimicrobial coating may be formed on the air-contacting surfaces of the evaporator core. The antimicrobial coating may comprise an ionic material having immobilized ionic groups of one type of charge and mobile counterions of another type of charge. The mobile counterions may be ionically associated with the immobilized ionic groups. In another form, an ultraviolet light emitting diode (UV-LED) may be used to direct UV light onto the air-contacting surfaces of the evaporator core.
