Air conditioning new building experiences?

Thank you very much for the feedback. Daikin is currently leading here. Question about the positioning of the outdoor fan, the house is on a slope, does a lot of noise reach the neighbors (red lines) above? Is it possible to install with an extremely short refrigerant line - 2 meters? The study is located directly behind the wall in front of the fan

Thank you mycraft. What do you think about Sarara Ururu? Really expensive and big, and the local distributor said they took it out of the program because the price-performance ratio doesn't fit

Daikin is expensive, let's not kid ourselves. You just have to weigh it up. Basically, there is nothing to object to against TCL either.

I'll first get some quotes... My city (or rather village) administration in CH requires an approval process, including signatures from all neighbors... Well, well. Maybe I'll just go ahead and plan the air source heat pump as well.

First offer for 1 Mitsubishi M-Series R32 MSZ- AP25VGK Monosplit, with installation, over 4000, I would have expected that earlier from Daikin and not Mitsubishi.

Mitsubishi Heavy is at least as good as Daikin. They are hardly any different.

For how many split units?

Sounds rather cheap to me given current conditions. Our first (Mitsubishi), 3 split units, was a bit over €5000 in 2020. For the current one from Remko (5 split units, of which 1 unit is covered by the builder), just under €14,000.
We really waited here for months for an alternative offer beforehand (including Daikin, but also Mitsubishi), and our plumber could not even get the units.
