Last summer it was working ice cold. When winter came, I turned it off for about four months. And now that summer has arrived, I turned it on and it's blowing hot air and not cooling. I don't know what the problem is. I asked about it, and they said it might be the coil, or the compressor, or it might be out of freon, according to the technician. Anyway, the AC is for sale as is. Whoever wants it, God bless him.
