Yes they do. I have no idea what heat pumps you have, but air-air heat pumps can be found in every other house here in Norway.

- windexh8er 3y agoMy main unit (live in the northern part of the central US) can operate below -10F with no problem heating my house. It is a dual fuel system (natural gas + HP) and, normal operations I don't, normally, run the pump at those temps. I generally lock the HP out around 10F and let the system choose the heat source based on the conditions. Air source heat pumps are very viable in the northern climates of the US.
