In my Queens building, I mentioned my AC issue to a neighbor while waiting for the elevator. He laughed and said he almost called repair for the same thing last week but solved it himself after checking a few basics. That made me curious, so I read https://acrepair.ac/blog/before-calling-ac-repair-queens. It explained why some problems look serious but actually start from very simple causes that are easy to misunderstand in older city apartments.
