My wife doesn't like the idea of a heat pump. Her grandmother who lived in the N. Georgia mountains had one and every time my wife would visit her, she says she nearly froze to death. Per my wife, all it did was put out cold air. This was probably 20 years ago btw.
We're in the Atlanta area where we have some pretty cold weather at times in winter, and we also have those hot summers. I would do a duel fuel system with an 80% variable speed furnace if I went with a heat pump.
Without getting too heavily into politics, from what I've seen electrical rates might be hit harder than natural gas rates by a Cap and Trade program since so many power plants depend on coal. We have good electrical rates now, but if they did go up substantially in the future, a heat pump might not look like such a good investment.
