Yes. I live in Utah and have a heat pump and gas furnace. I am told the heat pump is really efficient at medium-cold temperatures, but not so much on really cold days.


I believe heatpump technology has improved over time. Also, "less efficient but still functional" is an adequate option for really cold days.


Less efficient but still functional means my home was 50 degree inside instead of 67 when it was -1 for two weeks here.

On older homes, with much worse insulation, this would immediately be a problem.

Heat pumps are great, but they absolutely need some kind of emergency heat back up.

No, that's just not functional. "Less efficient" means consuming more joules of electricity but still providing the required function.

They include it. You were sold an inadequate pump for your situation.
