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?

We have air conditioning in the large living area (65sqm (700 sq ft)) and in the bedroom and attic. No air conditioning in the kids’ room—they have to sweat. In the bedroom, it’s already running very quietly (no problem at night), set to 18 degrees Celsius (64°F) since spring because of my wife’s pollen allergy. The windows stay closed. The controlled ventilation system keeps the pollen out. My wife feels much better this way. The controlled ventilation system, of course, runs continuously as well. What I would do differently: definitely add an indoor unit upstairs in the hallway (large south-facing windows*). That would probably cover everything. The extra cost wouldn’t have been worth mentioning.

* daytime shading annoys me Have you tried if the air conditioning on the ground floor benefits the upper floor without turning it on up there?

Strange... why were we really envied by everyone last summer? They also all have modern houses here, including shading. If it’s hot for a longer time and it doesn’t cool down at night... how exactly is the air inside the house supposed to stay cool? Oh... wait, let me guess... you open the fridge?Dear Steffen, considering the law of conservation of energy, that probably won’t work. But unfortunately, not everyone understands physics. Long-lasting tropical nights don’t occur in Germany either. It’s nice that everyone envies you; that seems to be the most important thing for you. I rather find it unlikely. I don’t know anyone who enjoys living in a 20°C (68°F) refrigerator—it’s kind of an American thing.

Well, there isn’t much to consider. Cooling the bedroom and living area already makes the whole house comfortable.Unfortunately, that doesn’t work. Bedroom at 20°C (68°F), ventilation at max, and door open all day still isn’t enough to cool the upstairs hallway, and of course nothing reaches the conservatory.
@Lumpi: Sarcasm isn't for everyone, right? We don’t live at 20°C (68°F) in summer either, but we find 23–24°C (73–75°F) in the living room with outdoor temperatures above 30°C (86°F) much more comfortable, and 20°C (68°F) at night in the bedroom also leads to really pleasant sleep. It’s great if that’s not true for you. I don’t care... I love our climate control!!! There are plenty of people who tell us “such ugly indoor units ruin the whole look”—which is totally fine. But for us, it’s worth it...
