I don’t understand how the heat part works when it’s below freezing.

The element can cool the air below zero. They have to play games if it gets to the due point of the outside air to keep from frosting up however. Also, there is an efficiency hit, as the temperature differential gets larger. This is why ground sourced, or even water sourced are more efficient in colder climates.

As long as it above 0K outside, you can (in theory) transfer energy. Heatpumps meant for cold weather climates use a different gas with a lower boiling point than those meant for hot weather climate (aircondition). But other than that, they work exactly the same.
