How to choose between them
In a cold climate the heating side decides the system. Hyper-heat models keep running to -13°F or -22°F and hold more of their capacity at 5°F than standard models, which typically stop around 5°F.
Running isn't full output: near its limit a heat pump delivers well under its rating, so homes that often see those temperatures keep backup heat. Check yours with the cold-climate check.
