It's been between 108 and 100 consistently now here, so i finally am using the AC unit. Also, the biting gnats go right through any open screens, and they make me get long red welts. So as predicted, the gnats drove me to the AC.

What's nice is I have a very small area to cool. A small window unit does the whole studio and uses 270 watts on the Low and Energy Saver Settings. I also keep the AC temp within the 70s-80s (and off when i am gone), and use fans to cool down my actual 'use area' = either the bed or desk.

So far my bill hasn't risen! I am sure it will next month. We will see.
