The overwhelming majority of even high end cold climate ASHPs do not function at -40 C/F. -20F, that’s doable.

HelixDab2@lemm.ee 11 months agoNot correct for modern heat pumps. They work down to at least -40F without switching to creating heat.

That’s why I said it depends on the type of the heat pump. Some can go really low, the cheaper ones not. At some point (the latest at -273.15C :D) they need to switch.
