I actually can't wait for summer to hit again, I'm about tired of the cold weather, but it's been beautiful here the last few days. in the summer here, I average between a $350 - $400 electric bill!! I tend to leave the AC on 24 hrs a day during the summer. if I shut off the AC before going to work during the summer, it takes so long to cool the house after I get home, it's really unbearable. I buy a ton of gadgets, but this is one I hope will pay for itself over time. I'm looking forward to seeing how it affects my electric bill this summer. now all I need is a windows 8 app for my nest!!
