Is an air conditioning system necessary for the attic with a roof pitch of 35 degrees facing south, featuring two roof windows and a dormer on the south side? The rooms on the south side, arranged from west to east, are an office, a children's room, and a bedroom.
Opinions vary widely on this. A heat pump with cooling function and a mechanical ventilation system with heat recovery will be installed.
At the moment, the plan is to at least equip the south-facing rooms in the attic and possibly also the ground floor (living/dining area) with air conditioning.

A brief update:
The system has been ordered and will be installed no later than July 13th. The attic is already cleared out, and by the weekend at the latest, I will run the 3x4.0mm² cable from the fuse box to the chimney flues in the basement. They will handle the rest of the route since they will be coming down there anyway to install the condensate drainage. I just need to drill a suitable hole through the approximately 60cm (24 inches) thick former exterior wall.

That was really quite fast, I have to say. I’m looking forward to your further updates.
P.S. What is the total length of your piping? I’m asking because the system is prefilled for 30 meters (100 feet) of piping, and for every additional meter, you need to add 20 grams (0.7 ounces) of fluid. I’ve heard that some companies tend to forget this.
I didn’t do it myself (installed the system as a DIY project) because I misinterpreted the technical data. I fixed it quickly over the weekend, and since then, we almost need winter clothes.

Let me guess, it’s 31 or 32 meters (34–35 yards)! We’ll know for sure after installation, but that’s the estimate and it should be accurate. Thanks for the good tip; I’ll keep an eye on that as well.
Yes, this is really quick, and so far I can only report positive experiences. You’ll also find only positive feedback online. The company has been family-owned since 1979 and is locally based. From what I can tell, all technical statements have been spot on. As I said, they recommended a dedicated power supply line right away, and according to their calculations, 24 amps with 3 x 2.5 mm² (3 x 5.4 sq ft) cable is suggested, but 3 x 4.0 mm² (3 x 8.1 sq ft) would be better.
It was also their idea to drain the condensate down into the basement and install the condensate pump there.
But yes, I’m happy to keep you updated!

So, the first installation day is over, and the very positive impression was confirmed. They were scheduled to arrive at 8:30, but at 8:28 they called to say they would be 10–15 minutes late because the painter’s fleece was not delivered. Everything was laid out perfectly and then reviewed and discussed again. Yesterday, they hung the indoor units and worked very neatly and tidily. The access to the chimney in one room is perfectly covered by the unit, and the pathway to the attic floor in the bedroom is also very cleanly done.
I think today they will continue with the piping; I’m curious how everything will work around the chimney, but we have three flues available for free use. The installation of the 71kg (157 lb) outdoor unit will also be exciting. It has to be brought out through the Velux roof window (the sash will be removed) by four workers, and the roof workers will be secured with harnesses (very exemplary). Let’s see, so far the impression remains very good. Condensate will be entirely drained into the basement; only one indoor unit (bedroom) requires a condensate pump upstairs because it has to go through the attic.
