I have two working window AC units. Read this description please. The larger 10,000 BTU unit is a Frigidaire FFRA1011R11. It cools and runs great, but is EXTREMELY LOUD. I used it in my work area so it didn't matter that it was super loud. The smaller 6,400 BTU unit is a GE AEZ06LQW1. It runs and cools great, but the bottom edge of the outside of the unit gets very hot. I have used it for years in my work area with no issue from this. These are used, but working and blowing cold. Selling for cheap. $50 for the larger one and $25 for the smaller one. $60 if you take both! Cash only.
