Who is responsible for ac brackets ?

[Mathew Fuentes]

Hey everyone . So I have a tenant where her ac is leaking and rusting down the vinyl siding . I went out there and cleaned it because I am house hacking at this location. The ac isn't sitting on a window bracket by the way. Will installing a AC bracket help with this issue? Also are Landlord's responsible for providing the bracket ? I looked and haven't seen anything that says we're responsible for it .

thank you in advance .
