We opened the air handler and accessible room outlets to assess the blower and connected air passages. Our technicians worked at ceiling openings with service lines, while a large collection hose connected the system to the vacuum truck. Negative suction draws loosened contaminants toward collection and helps contain dust during agitation. Protective coverings shielded nearby surfaces during access. The selected photographs document component condition, the cleaning setup and work in progress; exterior duct deposits and material condition remain visible in the attic inspection views.
