That used to be sound logic for air source heat pumps, but the newer tech ones do work in cold temps. The one I installed will output 80% of it's max rated BTU down to -22°F outdoor temperature. That's rather amazing compared to the old traditional single stage units. No need for backup heat.

Mine is a "MRCOOL" MDU18024036 I believe they are rebranded Gree units. It's a lower-mid level performance unit and still makes me very happy!
