As I said, I am surprised heat pumps work effectively in Canada. It seems too cold. I think my heat pump in Atlanta cuts out below 40 deg F, and the aux gas heater comes on. See: https://www.estesair.com/blog/at-what-temperature-does-a-heat-pump-quit-working-efficiently Heat pumps do not operate as efficiently when temperatures drop to between 25 and 40 degrees Fahrenheit for most systems. 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.
