So far, yes, my AC has been fine with the top vent covered by the cushion, and I was nervous about that! No change in how my AC works/cools my apartment, and no overheating. I can update this answer when I remove it at the end of the summer, because I have wondered if the cushion being over that vent might rust the unit over time. But, regular rain already rusted my AC, as did the towels I kept desperately stacking on it to stop the awful noise, so I doubt this cushion could possibly be any worse! I am so happy with the now-silent rain and dripping ACs from upstairs neighbors.
