In my local market, if you ask an installer for a heat pump, you get something from Japan or Korea. I’ve never encountered an American unit.
(I’m referring to normal air-to-refrigerant-to-air heat pumps. I know of a really weird system that is thoroughly American and an utter pain in the arse to replace because it’s specialized and undocumented. It’s quite loud, too, because it’s single-speed, and that single speed is waaaaay too high.)
