Hello: Heat pumps work better in higher ambient temperatures (within reason), so depending on climate may have a lower coefficient of performance (COP) in winter. In unhappy situations, COP can fall under one. That’s why I answered as I did. You don’t want the heat pump to go into electric resistance heating mode. 😎

Yours, Larry
