The selected photographs document dust on the blower wheel and accessible cabinet surfaces, dark deposits at multiple metal supply boots, and damaged lining near cabinet penetrations. Hygienic Air protected the work route, opened and assessed the air handler, removed the blower assembly for component access, documented wiring for reassembly, and cleaned accessible boots and components. Later views show cleaned accessible openings and a light-colored restoration coating across the photographed lined compartment, followed by completed access restoration. The process addresses accumulated material at both the equipment and duct openings; visual deposits are described as suspect microbial growth only and the coating does not correct an underlying moisture source.
