Is this some country specific terminology? At least in Australia I've never seen an air conditioner that didn't use heat pump technology. Aside from evaporative cooling that is.

Air conditioners (the things that can make a room colder, but not hotter), are indeed heat pumps, but in the US when we refer to a "heat pump" we mean the same technology, but with a reversing valve so that it can make rooms both colder and hotter.
Interesting. I’ve never seen one that couldn’t heat and cool before. Even crusty 30 year old window units can do both. Seems almost absurd to not utilise it both ways.
