I have a heat pump in New England, and it works but damn is it expensive right now. I think I need to upgrade to a bigger pump. My aux heat is kicking on semi regularly, and the heat pump is running it's reverse cycle pretty regularly. I think heat pumps are an absolute no brainier. They work great for AC during the summer, and they heat my house really cheaply in the fall. I'm disappointed in my pumps winter performance, though.
