Over in Palm Springs, they have SoCal Edison and $1000 monthly electic bills are not uncommon. We here in the east valley have another provider with much better rates, but $300-$400 per month isn't unusual.
It was 111 degrees yesterday, and when I looked at 10am, we'd hit 100............and our A/C took a crapper last night - weekend, of course.
Like the one I described? Easily. Then add in the pool pump which runs 8-12 hours a day in the hot months, you are easily up to $700-$900 a month. I have heard stories over over $1,000 a month. Plus an upstairs gets so much hotter and erlier. With a one story, I can go to about mid May without air unless it's unusually hot ( I like the heat though and it takes a lot to make me uncomfortable). The two stories need air many more months a year.
I have about 2600 sq ft on one floor and with the pool pump, even my high bills in July and August will get to the near $400 mark. (and increasing with rate hikes all the time). But then, in the cool months, they are next to nothing.
