George, you only convinced your old geezer friend of something he desperately wanted to believe: That he could have warm air coming from his vents without paying extra for it. It's a well-known fact it's easy to convince someone of something they want to believe. This peculiar facet of human nature has been exploited for centuries by con artists, faith healers, Nigerian scammers and other charlatans. Case in point: you've convinced yourself that your resistance heat is economical to operate, when of course it is not.

Now even if I accept your assertion that heat pump COP can go below unity under certain conditions (and I doubt it), any loss of efficiency is more than offset by the higher COP at warmer temperatures. Do you heat your home during more days in 20 to 40 degree temperatures or in zero to 20 degree temperatures? That one's not hard to figure out; there are more days in the year with temperatures in the twenties and thirties than there are days between zero and twenty.
