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.

I certainly hope so, so that the purchase was worthwhile
We also chose the 10kW Daikin outdoor unit, but with 5x EMURA indoor units.
The installation effort and costs were kept reasonable since we did everything ourselves.
P.S. The app control works perfectly as wellMay I ask what you paid for the hardware (outdoor and indoor units)?
I had an appointment with a building services company today... they are now preparing another offer. Let’s see....
The interior and exterior installation cost me around €5,000 (about $5,400), but I have to mention that our company is a partner of Daikin, so we received a good discount. Additionally, there was a special discount available for private customers.
If the HVAC company does not add any markup on the hardware or pass on the discount to you, the price should be at least €10,000 (about $10,800).
On top of that, you have to consider installation, refrigerant piping, condensate piping, condensate pump, electrical connection, and commissioning. I think the total could easily reach around €14,000 to €16,000 (about $15,000 to $17,200).

I’m bringing this topic back up because we are currently planning an air conditioning system. Our preferred option is a Daikin multi-split system, but now the question is: which series of indoor units should we choose? Comfora (which I’ve heard some minor issues about) or Perfera, which already includes app control? The Stylish version is actually not necessary, as I find it only marginally more attractive.
Otherwise, we are currently waiting for the first quotes. The rooms to be air-conditioned are 12/15/16/52m² (129/161/172/560 sq ft) in size, with a ceiling height of 2.25m (7 ft 5 in) for the first three and 2.90m (9 ft 6 in) for the largest room. The outdoor unit will likely be installed on the roof, since this allows the refrigerant lines to be routed best via the attic and the (unused) chimney, plus it provides easy access for maintenance. Another question is whether to drain all units with condensate pumps directly to the roof or to follow the advice of a very knowledgeable refrigeration technician and lead the condensate down through the chimney into the basement and then into the wastewater system.
Are there any other suggestions or recommendations regarding air conditioning? We are tackling this because in our older house, the bedrooms are under the roof and get quite warm in the summer.

I have experience using various Daikin multi-split and single-split systems, including Comfora, Emura, Siesta, as well as several older models.
Honestly, it doesn’t really matter which series you choose. Overall, when it comes to the indoor units, it’s mostly about the design of the plastic casing.
What kind of issues have you heard about? In my experience, 90% of the problems are due to a lack of proper maintenance.
Regarding the condensate drain, I would follow the advice to use as few condensate pumps as possible. Sure, they work, but they cause unnecessary electricity consumption and the noise level should not be underestimated. Despite being labeled as silent or similar, these pumps always switch on when you least want them to and are naturally louder than you might expect.

The problem described to me by another supplier (who would also install Daikin) was that the Comfora units can sometimes respond slowly. However, the impression I got from the refrigeration technician yesterday was very positive, and he also planned to use as few condensate pumps as possible. That fits with the good impression!
He also addressed maintenance directly; he said the indoor units generally manage themselves (but should be disinfected every two years), and the outdoor unit is apparently maintained very thoroughly.
In the master bedroom, avoiding a condensate pump is difficult because we need to go up to the attic to reach the other 3-flue chimney stack. But that’s just how it is; otherwise, we would have to open the wall again in the master bedroom (there is also one inactive chimney flue out of three there).
I’ll wait and see when the offers come in and which units are included; alternatively, we will also receive an offer from Remko. However, I tend to favor Daikin, because there isn’t much information available on air conditioning systems in general.

It’s always amusing. Homebuilders with heat pumps almost always claim they are practically maintenance-free and you can handle everything yourself if you ever need to service them every few years. Yet, in the same breath (and this isn’t directed at you), they say that split air conditioning systems are often too expensive to operate because of the required regular and extensive maintenance, etc.
So they contradict themselves without realizing it.
Regarding the condensate pump: If you still have the option, it’s better to open the wall. Especially in the bedroom, I would want as little disruptive noise as possible.
