My Mitsubishi Hyperheat units have a COP above 1 down to -15F and still work normally at 5F (northern New Mexico, 6000', overnight). You're getting bad information.

Mitsubishis can work down to -13F/-25C and have a COP of 2.08:

If you live in US IECC Climate Zone 4 or above look for a cold climate air-source heat pump (ccASHP):

You can also get things installed in a dual fuel arrangement where you still have a gas furnace that kicks in if it does ever get 'too cold'.
Probably have to be an earth-exchange system to deal with temperatures lower than 40°F, given that heating my house in winter is the use case.
