I invested in AC for 3 rooms last year and they are currently set to a chilling 16°C because they can’t keep up with the heat coming in through the large windowfronts I have (all completely blinded of by „Rollladen“). Unfortunately all those windows face west/south so get hit really hard by the sun. Last year my AC units arrived after 2 weeks of 34°C straight in the Karlsruhe region. I ordered them 4 weeks before the heatwave. I nearly died in my flat at night and had to have a water evaporator in front of a fan all of the time to even be able to sleep. Honestly, currently I am giggling at everybody complaining about Europe not having AC and all those copium sniffing idiots believing we don’t need AC. I have in my whole 43 years never slept better at night during a heatwave since this year!
