I just got one installed last month in middle of winter at my home in New England.

The air from heat pump feels more comfortable than the dry air from the furnace. I got installed with a the furnace back-up option, that way if the heat-pump can't generate the heat, it switches to propane (it becomes very cold here in New England in Winters). From my experience, the heat pump is working well in 30F and above weather (-1.C)

Heat pumps burn a lot of electricity, luckily I have solar to off-set that cost, although Solar generation is low in Winter, it adds up well over the year.

Heat Pumps + Solar is the way to go.
