Technically yes, refrigerators too. Around here (Australia) we call it 'reverse cycle' when air-conditioners can heat as well as cool, and probably over 90% of all air conditioners in homes have that functionality - it's just expected. But the term 'heat pump' seems to be used in a lot of places now to refer specifically to having the heating ability, even though cooling is doing the same thing (just in the opposite direction).
