Make sure showers are getting enough hot water and the temperature doesnt fluctuate. 

please set the gauge to your desired temperature ".

Depending on the temperature, A/C IS considered an emergency here in Florida.

I keep the AC at 76 during the day I believe, and around 72 overnight.2) Some of the newer smart thermostats (e.g. the Nest) have the ability to set a pin that is required to adjust the temperature.

@Bret Weigel some people will leave the temperature high during the day, then get home and crank it down 10 degrees and expect it to be instantly cool.

Did they change the temperature, so it needs to kick on?

What is the temperature differential between the cold air return, and the vents?

The vast majority of homes here are built without A/C both because energy is much more expensive here and because temperatures rarely get above 80 degrees.

There is a temperature setting on the burnerTURN IT WAY LOWER!

.- the high humidity is likely caused by a combination of factors: moisture transmission through concrete walls and slab floor, lack of air circulation due to no forced air heating, lack of dehumidifier, cyclical air temperature changes in the home.- the condensation on the walls or windows is primarily due to inadequate insulation and dew point problems caused by cyclical air temperature changes in the home.These problems can be solved with the installation of a proper dehumidifier, improvements to insulation and properly utilized vapor barriers, increased air circulation through the use of ceiling fans, proper furniture placement (not right up against exterior walls), etc.
