I moved into a upstairs apartment- studio 425 sq feet. The building is a 2 story building. It was built in 1971.
I had a bad musky meldew smell in my apartment. My AC broke and the landlord placed a brand new one in, which helped a lot.
However, I still retain some of that sour musky smell in the apartment. I have 3 ac ducts and here is what one of them looks like in the photos.
Strangely, I still smell the odor with the windows open and AC off. But I guess it's the ducts.
My question is, I have read that some AC ducts are beyond cleaning. I don't mind spending money to get them clean just to get rid of the odor(if they are the cause). Does anyone know if these ducts are beyond cleaning or can they be cleaned? The pics below are of just one of the 3 air ducts.
