I was expecting a higher electricity bill because I’ve been using my a/c on the hot 90+ degree days we’ve been enduring. I was not however expecting a bill that was nearly double that of my previous month, holy crap. I guess this is why they have timers on some air conditioners. I left mine on during the night maybe three or four nights that were extremely hot. Okay, and then there was the time I got home and realized my apartment was mysteriously cool. Maybe I had already put on my iPod headphones so I couldn’t hear that the a/c was still on when I left, woops.
