At what temperature do heat pumps stop working?
A heat pump works best when the temperature is above 40. Once outdoor temperatures drop to 40 degrees, heat pumps start losing efficiency, and they consume more energy to do their jobs. When temperatures fall to 25 to 30 degrees, a heat pump loses its spot as the most efficient heating option for an Atlanta home.

At this stage, the body is still doing what it’s supposed to.
