ABSTRACT:
A method for removing harmful microorganisms from an air conditioning system and for treating said system so that the microorganisms do not return to the system after the cleaning. The first step of the method includes a thorough mechanical cleaning of the system, including the step of removing loose dust and debris with a vacuum cleaner or any vacuum method. The mechanical cleaning is followed by a chemical cleaning. Isopropyl alcohol or any like substance is the preferred chemical cleaning agent because it acts as a microbiocide. A long-term microbiocide is also applied to the cleaned surfaces. An adhesive is then applied to the cleaned surfaces, and a liner of plastic or foil is placed in overlying relation to the cleaned surfaces to hold any loose insulation that might be present and to provide the system with low particulate buildup in the future and to prevent the return of the microorganisms. This lining will also provide a surface easily cleaned in the future.
