Hello,
We are considering planning for air conditioning preparation in our new build.
In which rooms does it make sense to install air conditioning?
We have a KfW 55 semi-detached house.
What needs to be done for air conditioning preparation?

Deliverer8 Feb 2022 15:03My wife collects the condensate because carnivorous plants really like it. No joke!
I want to post my question here because it fits the topic quite well.
When we compared prefabricated house suppliers back then, none of them offered to prepare the building for a KfW40 standard, including our current provider. Since we unfortunately will not receive any subsidies, I am now revisiting this topic and would like to ask you, before contacting my house supplier, what exactly is needed for the preparation and what the approximate costs might be.
A brief overview of the key details:
Our preference is for a split air conditioning unit, with the indoor unit to be installed on the upper floor (bedroom). Directly above is the cold roof of the 12° (approximately 21°) pitched hipped roof. I mention the roof pitch because I am considering the possibility of mounting the outdoor unit on the roof (are there any reasons against this?).
Could someone provide an estimate regarding this?
Would it require significantly more effort and cost to plan for a potential second unit for the ground floor as well?

Bauenaberwie18 May 2022 19:28For us, the preparation for two indoor units and therefore also two outdoor units costs about 1300€ (approximately $1,400). All in all, we would have been around 4,000€ (approximately $4,300), but we are waiting for the subsidies first. So definitely prepare for both right away!
Oh, so much just for the preparation... I didn’t expect that.
Can you explain the tasks involved in more detail? What needs to be done? What is required for the preparation?
And where would you have installed the outdoor units? I wonder if it’s really possible to mount them on the roof given the low roof pitch.

Stefan00119 May 2022 08:29We had the entire installation done during construction, but the difference is minimal. Up to the final stage.
Ultimately, it’s about installing the refrigerant lines and electrical wiring, and depending on the system, also condensate drain lines.
The only thing left is mounting the unit on the wall and roof, which is not significant in terms of workload.

We have five indoor units and one outdoor unit... I wouldn’t know why anyone would use two outdoor units (the distances outside are usually too long, which is almost never the case for a single-family home).

And where would you have installed the outdoor units? I wonder if you can really just mount them on the roof given the low roof pitch. You need a double refrigerant line and power supply for each indoor unit to the outdoor unit (possibly also an extra BUS cable, depending on the manufacturer). You should also consider how to handle the condensate (where to drain it, with or without a pump).
It is possible to mount units on the roof, but they must be securely fastened. However, this will add a significant extra cost, since an outdoor unit weighs far more than just 5 kilograms (11 pounds).
