The report gives results of a project to develop and refine surface and airborne contamination measurement techniques that can be used to evaluate air conveyance system (ACS) cleaning. A pilot air conveyance system (PACS), using full-size residential heating and air-conditioning (HAC) equipment, was constructed and operated to provide a controlled, artificially soiled, ACS environment. The PACS consisted of ducts, an HAC unit, a dust mixing room, and instrument room, and a dust generation and injection system. Three types of duct systems were evaluated with the proposed measurement methods under soiled and unsoiled conditions. Each duct system was then cleaned by professional ACS cleaners and reevaluated. As a result of the pilot study, the surface contamination measurement methods were evaluated over a range of conditions and improved. The significance of acquired results in an actual residence was not determined.
