A/C guy who's the son of an A/C guy here. Heat pumps lose efficiency the colder it gets. I wouldn't bother with one if you're in a northern climate. Lower midwest, you might be able to save money with a heat pump over natural gas, but it will depend heavily on the cost of the respective energy. For me, in the central US, we have great prices on gas and somewhat crappy prices on electricity (vs most surrounding regions) and it's definitely cheaper for me to stick with gas heat.

Thankfully heat pumps have gotten better since your father's day. And natural gas is only going to keep getting more expensive. For a price of equipment that will last you 15-25 years it's becoming harder to justify gas heating.

For new builds ground source heat pumps should become more standard, they cost more, but they'll save a lot in the long run.
