The selected photographs document the cleaning setup, connected truck-mounted vacuum, branch agitation through protected register openings, accessible return conditions, restored plenum access, and dryer-termination lint removal. Hygienic Air used mechanical agitation while sustained negative suction drew loosened material toward collection and helped contain dust. Later views show cleaned accessible branches, a reinforced plenum closure finished with mastic and metal foil tape, and a roof dryer termination with accumulated lint removed. Dark long-standing staining remains visible in the return lining, along with a damaged edge, exposed insulation, and a collar-to-lining gap that remain documented for evaluation rather than represented as repaired.
