ᐅ Preparations for Central Air Conditioning in New Construction

Hello everyone,
We are currently discussing the purchase of a newly built single-family house from a developer. Unfortunately, the developer has decided to use gas boilers for heating throughout the entire development. This means summer cooling via heat pump is not an option. We have been considering making preparations for a future air conditioning system.
This raises the question: What should be installed or planned during the construction phase to make it as easy as possible to retrofit a central air conditioning system later? Is it always necessary to have an air conditioning unit in each room, or are there systems where you only have air outlets in the ceiling and a single control unit located in the utility room?
Thank you very much!

I don’t want to have a "climate unit" mounted on the wall in the room itself. My understanding is that this is addressed by a central air conditioning system. Yes, that’s correct. But there are also ceiling cassette units, etc., so nothing has to be mounted on the wall.

Are the same duct types used for the air conditioning ventilation as for a central ventilation system, or do they require different dimensions? For effective cooling, you need roughly four times the amount of airflow. So yes, the ducts must be significantly larger in size.

Do you happen to have a good link where I can read detailed information? I only find marketing and high-level comparisons of different types of air conditioning systems. Links are not allowed here, and this is really something for a professional planner. You can easily waste a lot of money. In other words, it’s not really a DIY topic.

Does a central air conditioning system affect the KfW55 standard status? I’m afraid it might not. Most likely, it’s actually the opposite, and the standard can be easier to achieve with air conditioning.
Heat pumps for heating are allowed and even encouraged in some cases. An air conditioning system is essentially the same.
Really? I only know that there are problems with split units, so I assumed it would be similar with central systems.
The question is probably whether a developer will agree to so many extra requests. The additional costs will likely be significant, based on my experience with developers.

For a central system, you can expect prices starting from 30,000/40,000/50,000K and up, depending on the size of the house.

This is due to cost reasons and because the companies would probably not be interested in doing it later. For now, I wanted to find out what kind of preparations are actually necessary. Possibly, it might be enough to have the ducting installed first and observe the actual heat generation over one or two summers. You never get the new build condition again.
In principle, it’s definitely a good idea, but if you want to prepare for it, you need to know exactly what you want. For that, you should consult an appropriate planner or designer.
As mentioned in the thread about air conditioning on south-facing slopes, I’m currently having a multi-split air conditioning system retrofitted in an older building. If you want to pre-install it, of course you need at least the appropriate ducts for running the pipes, and depending on the situation, also the installation options for ceiling cassette units, if you don’t want a wall-mounted unit.
