Well I have a completely opposite story. With our properties we have over 50 aircons, 80% being Daikin. And other than a shorted electronic board in one unit (lizard) which was still under warranty I have never any problems with Daikin (as opposed to some of the LG and Samsung I had previously). Daikin inverter units are excellent.
On our apartment complex I now replace with 'hi-sense', mostly because of the cost (and some of the other brands like 'hi-sense' are a good buy).
So for me Daikin, yes are expensive, but in my opinion one the best on the market at that price range.
Of course there will be a few more posts disliking them, but at least you have my opinion.
