Sales are growing so quickly that some installers wonder whether heat pumps could even wipe out the demand for new air conditioners in a few years and put a significant dent in the number of natural gas furnaces.

Air conditioners literally are heat pumps.
Technically, but they’re only one way.
The ones sold as “heat pumps” can operate both directions-- cool the outside world/heat your home in winter.
Huh. I had wondered whether air conditioners could be made reversible. Neat.
Another commenter claims all you need is one more valve. I suspect the design changes are slightly more involved than that, but in principle it’s certainly doable.
I would rather cool the outside world in the summer.
