Because at some point society decided to call them refrigerators or AC. The thing *inside the refrigerator or air conditioner" that makes it work is called a “heat pump” – that’s the unambiguous name of the device. Just like the bit inside a car that provides motive force is called the “engine” or the “motor”.
The device that uses a heat pump to both heat and cool a building is actually called an Air source heat pump, but since that’s a mouthful most people simply call it a “heat pump” to distinguish it from traditional AC that only works to cool an area. Sure, maybe you get that odd area the calls it something different (my region calls soft drinks “pop”) but that’s not the norm.
Round here we call that bit the compressor, as in “Need a new fridge/AC unit… compressor’s broke.” The term generally encompasses the compressor and the condenser, even though they are separate bits witch, together make a “heat pump.” I’ve never heard it called a heat pump in that context though (USA).

Nope you can have AHSPs that only heat. The Wikipedia article even says so.
