Maybe it works in Switzerland due to high altitude reducing humidity? I have a gas fired hydronic heating system but I still need AC for cooling(mixture of traditional and mini-split style units due to retrofitting requirements). I'm also located in a high altitude location but for AC alternatives here we would typically see something like a swamp cooler.
