Dear community,
My wife and I are currently working with a general contractor to dive into the detailed building planning.
One of our main concerns is a proper air conditioning system for the house.
The project currently includes about 300m2 (3,230 sq ft) of living space plus a basement (ground floor + first floor + attic); KFW 55 standard plus photovoltaic system (sizing still to be decided).
We both have previous negative experience, having lived for over 10 years in apartments where indoor temperatures in summer uncontrollably reached 32-35°C (90-95°F). This has to stop.
Therefore, our original idea was to plan for air conditioning units in the key rooms right from the start (individual air conditioning units). Now I also understand that a heat pump can cool a few degrees below the outdoor temperature. At summer temperatures above 30°C (86°F), that would not be enough for me.
So my question is: do you have any experience with this? Does this thinking make sense, or would you say that a proper heat pump with cooling function is definitely sufficient?
Of course, we are aware that whole-house air conditioning adds extra costs. But is the investment worthwhile?

There is no technical difference between ducted units, only an aesthetic one.
Unless, of course, you opt for a complete HVAC system like those commonly used in offices. In that case, you get an all-in-one unit with dehumidification in summer, humidification in winter, and all related features. However, those usually start at around 50,000 (currency).

May I ask, related to this topic, what temperatures you currently have in your kitchen and dining room? Last year, we roofed over our south-facing terrace and covered it with tiles. Since then, the sun doesn’t hit these two rooms as intensely anymore (kitchen faces southeast, dining room southwest)… on the west side, we keep the shutters closed… KFW 55 house… 26°C (79°F), I’m melting…

For us, it’s a given that we will include this component. The only decision left is whether to install a central HVAC system or split units.
With rising temperatures in Germany, 24°C (75°F) on the ground floor feels too warm for me.

In the evenings close to 23.5°C (74.3°F). Upstairs generally about 1 degree higher. Mostly shaded and passive cooling achieved through the underfloor heating system being active.
