Running the AC's full time
Since around Independence Day, the weather in our area has been warm and humid. Not exceptionally so, at least not all the time, but just enough to make it uncomfortable to sleep and -- in my case, since I work at home -- uncomfortable to work. So we've been running my poor three window AC units pretty much full time, around the clock, for weeks.
I'm terrified of what my electric bill is going to look like at the end of this month, but every time I step outside, I'm relieved that the electricity is on and working.
