Yes. I don't get that hang up. I bought new apartment in 2024. It has triple pane windows, and 20cm of styrofoam on the external walls.

I can cool down entire 70 square meters apartment with single 3.5kw split; that has worked well in the recent 40 degree heatwave. It does not even use "higher gears" to maintain the 24-25 degrees inside.

Not to mention it's usage overwhelmingly correlates with sunshine availability.
