How cool should my house be if it's 100 outside?

More specifically, for our area, most systems are designed to lower your indoor temperature about 20°F from the outdoors. So, on days when it's 100°F outside, and your system is running at its peak efficiency, your indoor temperature will likely never maintain a level lower than about 80°F.

Why is my house so humid with the AC on?

The inside AC unit has a cold evaporator coil to cool down the air. In this case, the water condenses on the evaporator coil (which is why your AC has a condensate drain line.) So as your AC runs, it's pulling moisture/humidity from your air!

Should I keep my AC fan on auto or on?

AUTO is short for automatic. The fan only turns on when cooling or heating (in winter) is required. If you can tolerate most of the summer heat – save for the absolute hottest of days – you'll want to use the AUTO setting. The AC fan kicks in when needed and stops running when the job is done.
