Dan, I've lived with heat pumps since 1979 - the earlier ones had resistive backup heat that did come on below freezing. This new one doesn't have any resistive elements. In our main house, we have geothermal, and occasionally the resistive elements would fire up, but I've pulled the cut-off on them so we just have the geothermal now and it's been just fine, even below 0F last winter. No, they don't blow hot air, and the warm air does blow more than a hot air system would, but it's not a problem, at least for us. YMMV. The new mini-split is in the 700 sq ft "guest house" where my wife is now growing veggies all year round -and it replaced a couple of window units (one was a heat pump) and some electric space heaters. The electric use is about a third of what it was last year. When we installed the geothermal in the big house, our total energy cost was cut in half. We're very happy with both of them.
