Ok but you can use AC in the winter as well, you've an use it only to dry the air in your apartment. So this is not a real argument to me once you know what it can do and how it does it, there is no reason not to have one. Outside it is 25°C but I still run my AC at 22°C and it is super efficient as this is the case where AC excels at efficiency when the diff is small. It is a heat pump, sometimes I would run it when outside is colder and inside is veru warm as it moves heat faster than opening the window and waiting.

I know not AC are/were heat pumps but I don't know of any that are not anymore

You can still buy a cooling-only unit no problem. Slightly cheaper than a heat pump.

Yes but still, I don't think it is worth it when you can heqt with it more efficiently than burning gas or coal.

		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.
