There are specific inverter driven cold climate heat pumps. Fairly new to the market and very efficient. Fujitsu and others. "Normal" heat pumps require some form of either resistance or gas/propane heat when its below 40 or so-my older system uses propane hot air as back up for the main system, elect resistance for the smaller.
