Hello
Has anyone retrofitted an air conditioning system in their newly built house? We wanted to include it during construction, but everyone said, "You don’t need that." Of course, that was nonsense — even with the best insulation, summer can be unbearable.
Our idea is to install an air conditioning unit on the roof, then route it into the attic (which is unfinished), and from there mount 2–3 indoor units on the upper walls of various rooms through the ceiling. Running the lines into the attic is quite simple, and you can easily access the ceiling (except for avoiding damage to the vapor barrier). The pipes won’t be visible since the units would be wall-mounted near the ceiling.
We don’t need air conditioning on the ground floor.
What kind of price should we expect including installation? Does anyone have a rough estimate? We want decent quality components, but nothing too fancy. I recall reading that there’s one main manufacturer dominating this type of system.
Is a budget of around €3000 (approximately $3200) realistic, or is that wishful thinking?

I have been thinking the same thing. For me, it would probably be two units. Without having researched it extensively, I would estimate around 4,000 to 6,000 (currency) for [very good, quiet] units including installation. I would definitely choose something of high quality.

But one thing I definitely got right, and my wife said several times in 2018, "That was the best decision" -> air conditioning from the start. The cost was about 10,000 EUR for high-quality Daikin units. Daikin is top quality. All piping, etc., is installed under the floor. Only three rooms are air-conditioned, with a total area of about 100m² (high ceilings). It ran almost the entire summer. Electricity costs were low, around 170 EUR, and absolutely worth every cent. Retrofitting is definitely more expensive... what most people forget: you need a drain for every indoor unit, and it must go downward. Pumping upwards is always problematic and often eventually clogs (due to dirt), and then you end up with water leaking into the room...
