Nope, 1 month!!!

I have never had one over $100 in my life. I freaked out when I opened the envelope!!!!
With the temps dropping under 0 a few nights in the past couple of weeks, we have had all of the heaters on (electric heat)--one in each bathroom (2), one in each bedroom (4), and one in the basement, and one in the living room--total of 8, and our front door wasn't sealed very well to begin with, so I suspect a lot of warm air was seeping out that way (but it has been fixed).

We also recently just put a couple of air filters up, and someone said they really suck a lot of electricity They work wonderfully with 4 dogs around though!!

As soon as I opened the bill, I ran around the house turning everything off--I would rather wear 5 sweaters and 8 pairs of socks, then have that kind of surprise greeting me again!!!!
