What needs attention
A new grille does not explain the system condition. Replacing a visible cover can leave a question about the component behind it. Which actual surface and moisture finding should be documented before further mechanical work?
A replacement grille answers only a visible-cover question
A new grille can change appearance without establishing what is behind it. Provide the earlier work record and the present component observation rather than assuming the system was fully assessed when the cover was replaced. The actual claimed surface and material need to be identified by the responsible professional.
Ask what mechanical evidence supports further work
The proposal should distinguish inspected system sections from inaccessible components and name any unresolved moisture condition. If a finding concerns only the adjoining finish, it should remain separate from a duct scope. Cleaning or replacement recommendations need component-specific evidence rather than the old or new appearance of a cover.
Access for the affected space
If an affected room is part of a recently altered space, bring the relevant repair and remodeling records. An alteration timeline helps frame questions but does not prove what caused a new mark. For the cooling system, identify the actual unit and the person responsible for mechanical access and repair.
