An aerosol air and duct treatment apparatus for treating the ducts of central air conditioning and heating systems and the air flowing therethrough is disclosed. The apparatus includes a housing which received on the exterior of a central air conditioning duct communicating with the interior of the duct downstream of the existing return air filter and fan unit for discharging air treatment chemicals into the air flowing through the duct, and is connected to the existing electrical circuitry with an adjustable timer and is manually operable by a push button switch to control the operation of an aerosol dispenser for a selective period of time and to run the existing fan unit for a selective period of time following the operation of the aerosol dispenser to distribute the air treatment chemicals throughout the ducts and into the rooms served thereby. After operation, the existing air conditioning and heating system is returned to a normal operating condition. The aerosol dispenser may be a conventional canister containing disinfecting and/or deodorizing chemcials under pressure which is easily secured within the housing and replaced when empty.
