Thanks. Living in the Houston, Texas area, it is hard to imaging life without A/C, although I don't mind working/playing outside in the heat.
There are a few weeks during the summer, when we need fans for certain. I have never lived in a house with A/C.
My office is across the street from the ocean, and has neither A/C or heat. In the coldest part of the winter we are careful to keep doors and windows closed, and a couple of people have electric space heaters. Not me.
When they try to sell me the solar panel system, they ask how high is your electric bill. I stop them right there. I know they are looking for $100-125 as a breakeven point. Mine is far below that.
It is 76 F right now at 4:40 pm (down from high of 77 F), heading for a low overnight of 65 F.
If you can become accustomed to suffering through days and nights between 65 and 75 F for months, you will be okay here.
December is high 63 F to low 49 F, on average, the coldest month. Then we must suffer wearing sweaters.
