 Frankly, at that point, nobody's saving money, right? Right. But the heat pumps today with inverter technology is we have full capacity below minus 15 degrees. So when it gets really super chilly around the beginning of the new year, at least where I live, then you're going to still get 100% capacity out of your unit beyond. So there is not a need for that, frankly, expensive auxiliary backup heat. The unit will do it all by itself.
