Here's an example then. It has pretty much been 90 to 95 degrees most days all summer. Humidity is 80 percent most of the time. Some people live without AC, and it's easier if you live right on the beach. If you live one house back the breeze is blocked. So, a lot of people AC their bedroom so they can sleep at night. It costs $400 to $600 Bz to do this. So some people AC fir a few hours and shut it off. Some people just use fans.
You can decide, what's comfortable. But in any case, given the 90 degree plus heat, every day, to live comfortably, it costs a lot. And, that is to AC one room. This isn't a complaint...it's just as hot in MD where I come from, but you can AC the whole house for less.
