Just a word of advice to anyone running a window unit (and even for some central units). As long as you set the temp below the room temp, the air coming out of the system is the same "coolness" if you set the thermostat to 50 or 72. However, if you set the temp below a goal that your unit can achieve, your unit doesn't shut off and give any ice a chance to melt off of the coil.
When it's really humid like this, you'll get a lot of condensation on the coil, and this can form an ice buildup. If this happens, you could end up needing to shut the unit off for a few hours before running it again.
I use window units on one floor of our house. When it's really hot and humid, I usually bump the setting up to 75-77 prevent them from building up any ice.
