Our old system will freeze up if it runs too long, I just leave the fan on and let the compressor cycle with the thermostat. Getting the humidity to 50% or below really helps the comfort regardless of temp. 77° seems to be our sweet spot.
The window shaker was struggling to cool office, i relocated it to the window on the shade side of office. Its way better now. 10x16 room is about 70 degrees. I need to put an awning on the south side, or something to shade the window.
