Fortunately we rarely need A/C. We do have an A/C unit in our master bedroom but only run it on extremely hot days and only long enough in the evening to cool the room to a comfortable temperature for sleeping. I generally close blinds and run ceiling fans during heat spells and this does help to keep the house cooler and air circulating.

Humidity is not generally a problem either, thank goodness. I can handle the heat but humidity just depletes me and I can so relate to the discomfort that so many have mentioned in this post. Stay cool and drink lots of water.
