Standard domestic central air-conditioning units don’t cope well with such temperatures. We’ll start the day with ours set to 72 degrees, but by late afternoon it’ll be ten degrees hotter than that, and stay at the higher level right through till bedtime. The only way we can cool the house further is to run a window A/C unit in our master bedroom, which pours cooler air out of its door into the main air intake to the master A/C unit. That, in turn, means the main A/C receives cooler-than-ambient air, which it can cool even further before spreading it to the rest of the house. By running the two in combination, we can get the house down to the mid-seventies by bedtime … and that’s the only thing that makes it bearable to try to sleep.
Mine does a little bit better, but not much: it’s been 78 or 79 in the afternoon.
I can only doff my hat in real respect to the original settlers here, who had to deal with such temperatures without even electricity, let alone air-conditioning. I know they built their homes to be as cool as possible in summer, but even so, I simply can’t imagine going through an entire summer of such heat without any escape. As for working outside during it, in the fields or on cattle drives, the thought just boggles my mind!
It’s funny to hear the National Weather Service read off the specs for a heat advisory, which includes “Stay in an air-conditioned room.”
If I ever have the opportunity to build a home to my own specifications, it’s going to be over-climate-controlled for its size, so that no matter what the outside temperature, hot or cold, it’ll hold the internal temperature I want. If Energy Star doesn’t like that, well, that’s just too bad!
It’s possible, I am told, to have too big a unit.
