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?

Our next house will definitely have an air conditioning system. I can only agree that modern, well-insulated houses become a nightmare in summer because there is no way to cool them once they have heated up. 29°C (84°F) in the bedroom, which faces north, was simply too much.

such ugly indoor units That was exactly our reason for leaving them out as well. Since we have a reversible heat pump, cooling through the underfloor heating system is possible to some extent. Last August, I set the supply temperature to a minimum of 20°C (68°F), and it worked quite well. The rooms stayed around 23 to 25°C (73 to 77°F), which was sufficiently cool for us. The electricity consumption for this was covered 100% by the photovoltaic system.
I have an air conditioning unit in my office. There is no drain there, so it probably needs to work with a pump. Since you can’t have wastewater running into the bedroom when retrofitting, the pump solution seems to be the only option. In theory, it doesn’t have to run constantly, only when there is enough water to pump out, including a collection tank.
I’m not looking for a big discussion about whether this is a good idea, but rather what price range I should expect. I looked at Daikin units. They have some pretty expensive models, but also more affordable ones. We only want cooling. We don’t need heating or dehumidifying. If anything, we’d prefer humidifying, but that would probably require a water connection, so that’s not an option either…

Last year, we also had air conditioning installed. Three indoor units: a larger one in the living room and two smaller ones in the study and bedroom. With plenty of piping under the screed and considerable effort to manage the water drainage, it cost 6,100 € (about $6,500). The units are from Panasonic.
In addition, we have installed geothermal cooling. This has already made a big difference—we maintained around 22°C (72°F) throughout the summer, and the air conditioners were hardly needed. Currently, we don’t have children yet, and the garden wasn’t fully completed. We’ll see how it performs next summer.
