    The big change that’s happened recently (if I understand correctly) is that there’s been a big upswing in usability/efficiency in colder temps. The newer models continue working well below freezing, and don’t necessarily require a traditional heating system for backup.

      Also using DC motors apparently is making a big impact in efficiency as well especially in window units

      If by recently, you mean decades. Cold climate heat pumps have been able to handle temps down to -30F for quite a while.

      The recent difference is just that they’re now being advertised, have articles being written about them, and most importantly… government subsidies to upgrade.
