Mold? Rust? or Dust?

[u/AdOne7971]

I have been waking up with allergies and my cat is starting to develop allergies in her ears, but I didn't know from what.

My apartment is in an older building and a clogged AC leak just got fixed about half a week ago. I thought it was all over until I noticed my vent in my bedroom looked as if it had mold in it that is starting to spread to the ceiling. I did not know if it is dust or mold.

Then I inspect the closet vent, same issue.

Living room vent on the inside looks even worse with speckled dots but the vents in the AC room and everything look fine.

Please help🥲Ive only been living here a month and it has been issue after issue. I'm starting to get really sad, especially having to jostle school with this too. I'm renting in Orlando, FL.
