Heat pumps aren't supposed to work below 32
Nah, they can work down to about 5 degrees. Any colder than that and they have heating elements (just like a space heater) that the fans will blow through the vents.
Edit: I did some reading. Even at 0F a heat pump is still more efficient than a heating element (like a space heater or electric furnace). Companies are working more and more on developing heat pumps that work well at temps well below zero. There's no physics reason they can't do it. Right now it's an engineering problem.

Maine is pushing and subsidizing heat pumps, and folks are buying them like crazy due to the high cost of heating with fuel oil. The modern systems can provide heat down to -15.
The Mainers often keep/have a backup system, whether a fuel oil or propane system, wood stove, etc., but in a survey from February to June of 2021, 7 out of 10 homes did not need to supplement the heat pump.
The heating oil and propane sellers are running ads, websites, etc. to try to convince people not to electrify, but they are losing the battle.

Ours is still rocking along at 68 degrees and it's 10 degrees out right now.
Going down to 0 tomorrow night so will report back in if it can't handle it.
