ABSTRACT:
A method is disclosed for cleaning HVAC ductwork, including the steps of transporting first and second modular filter assemblies to a site, connecting them in sealed fluid communication with one another and to the ductwork, drawing fluid through the filtration system from the HVAC ductwork, exhausting filtered fluid from the filtration system and tilting the housing so that any stairs present at the site bear against a bearing surface of an external conveyance assembly as the modules are transported up and down stairs.
