The new heat pumps are better and can work in most moderate parts of the country. Below 10 degree F temps may be a problem, and would require resistive heating (available in most models) or a gas backup. My MIL has a heat pump in Montana and it works pretty well. However, during the couple weeks a year of -20, the resistive units get a work out.
The issue on costs is the price comparison between kW and therms in your region. The MIL pays .15/kW and the alternative is propane. Her choice is pretty clear.
Here in Cali our power costs are outrageous (.45/kW and getting worse as we demand utilities underground lines for fear of fire.) I do not think heat pumps are economical here without solar.
With solar--and enough solar--the curves are closer. At least for heating. Then the issue turns on how much AC you need. Heat pumps are better than older condensers so it may pay off in hot summer temps...
