An apparatus for disinfecting the interior surfaces of air conditioning ducts comprises a pressurized aerosol canister (11) having a nozzle (12) and an elongated flexible tubular extension (14) coupled to the nozzle. The extension is closed on its free end and is provided along a portion of its length with an array of outlet ports or holes (18). When the nozzle is actuated, liquid disinfectant is delivered through the array of holes in the form of an aerosol spray or mist that issues in all directions from the tubular extension. In use, the end of the tubular extension is inserted into an air conditioning duct (22) up to a visual indicator (19) provided on the tube. The nozzle is then depressed, which causes an aerosol cloud to be expelled on the inside of the duct coating the interior surfaces of the duct and disinfecting against mold, mildew, and bacteria.
