If there is a heat pump rated to -14F and an area has historic lows of -34F it sounds like a bit more than just grifting going on. These people are setting up a system where, if everything works to spec, the customer may well freeze to death one winter. I don't know much about how heat pump performance degrades, but going in to a life-and-death situation where the main heat system is operating outside rated performance seems like poor planning.
