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.

- How do they plan to save on the refrigerant piping? Maybe they run it across the rooms, or the others made a measurement error.
- Labor hours are not always an indication of lower quality work.
- Did they offer you the same indoor units? If so, that statement is nonsense, or they want to sell it to you separately. The Wi-Fi controller for each unit is included with the Prefera units.
P.S. If you have a home automation system, you can also buy an interface from Daikin for all common bus systems. This allows you to configure much more than you can with the app.

@Dogma: No, the offer is for Remko units, so they can’t really be compared. For Remko, I would have to check how much extra WLAN costs. We don’t have a home automation system; our house was built in 1900. In theory, we could have installed it, but it wasn’t important to us.
The offer is calculated with 20 meters (65 feet), but that hardly seems right—the rooms nearby also need to have piping up to the roof at least. I trust more in the 30 meters (98 feet).
Of course, fewer working hours don’t mean worse quality, that’s true. But let’s say the extra hours just provide more buffer, although that’s only a minor factor.
In the end, what’s important for me is to have a very good feeling about the Daikin offer AND for them to be able to install quickly. After all, you want to get as much use out of it as possible this summer.

... the other 5.0 should cover everything.I think that’s more than enough. In my opinion, 3.5 is sufficient. For one, the attic is already cooled – most of the cold air probably comes down through the stairwell anyway. Also, I cool a 70sqm (750 sq ft) living room in an older building with just 3.5 kW, half of it directly under the roof...With air conditioning, it’s like heating: you want to avoid cycling and prefer to cool continuously at a lower output.
A small issue remains with securing the outdoor unit; a 25A breaker is planned with a 2.5mm² (about 14 AWG) cable, but 4mm² (about 12 AWG) would be better. Unfortunately, the route from the fuse box isn’t straightforward. Strangely, the second contractor didn’t require anything like this and, when asked, didn’t see any problems either—in fact, they intended to include it along the existing line upstairs.
However, the Remko model is also rated at 21.5A, so I assume that a dedicated line for the outdoor unit (for Daikin, it would be the 4MXM80N) is necessary, right?

Ok! That’s another argument against the Remko offer, since they didn’t require it.
I’ll check with the electrician right away for a solution. The only issue is that the route to the basement is inconvenient. We’ll have to open up the wall a bit, which was fully renovated just 3 years ago. The only advantage is that it’s hidden inside the shoe cabinet... It should be doable!
