At least in the UK, there's a massive move to heat pumps. The problem is that it's only for heating, through the usual central heating systems - so it just replaces the boiler. It's almost unheard of to have one for air conditioning. Usually people with air-con get a portable one that's only for cooling.

Unfortunately those portable units are scams aimed at people who don't understand how air conditioning works or what an air conditioner is supposed to look like.

I don't think they're scams. They are certainly not as good as a split heat-pump AC, but they work to make a small to medium room go down from 35℃ to 25 or so, which is more than enough to go from roasting to being comfortable.
