Not yet, at least, but close to (thanks, POTUS).

Back to AC... I have to fork out 4000€ to replace an aging AC in a small flat 60sqm (650 sq feet).

Just looking out of my window right now I can see 600 similar places, so that's 2.4mil EUR for a couple of (city) blocks.

As AC is to be added as it won't replace the winter central heating system we got in most condos -- well that's a lot of money.

Then you are being ripped off - I have seen 40000 Kč for a combined heat-pump/AC air/air unit here in the Czech Republic, which is about 1600 EUR. And you are getting a very efficient modern AC & heat pump.

Why won't it replace the winter central heating? Can't turn it off?

Or is it because you're in germany and the taxes on electricity actually offset your CoP (Coefficient of Performance)?
