The question is whether there is such a thing as a heat pump that's appropriate for use in the Northeastern US. It seems unlikely to me that someone with this person's level of engagement would have stupidly chosen to install the wrong kind of heat pump or chosen an installer incapable of recommending the best options.

I live in New York State and the government is nearing the point of banning gas installations in new construction here. I have yet to see any real cost benefit analysis for such a policy in a state with such cold winters.

I agree it's still a somewhat open question, but I think the data is that Massachusetts is probably on the side where it can make sense with the right equipment. Here's a real world analysis of a heat pump in Connecticut that averaged an full heating season COP of about 3.0: https://www.nrel.gov/docs/fy13osti/56393.pdf

I disagree that he's unlikely to have chosen a bad installer. They seem to have installed a non-cold-climate heat pump in Massachusetts. If that's true, I think it's strong evidence that they were not competent and should not have been trusted. I guess one could argue that this was a low probability choice, but I think it's as likely there were simply no more competent installers available in his area.
