no they don't. in some countries in europe (maybe in all of them?), installing airconditioning is frowned upon because it is considered a waste of energy. if you want government subsidies for replacing your heating system with a more energy efficient one you are not allowed to have airconditioning. and in the rest of the world only people/countries well of, that don't consider their energy usage, do it. airconditioning is luxury.

using to much airconditioning is also not comfortable. i used to live in singapore. we used to joke that singapore has two seasons: indoors and outdoors. because the airconditioning is powered so high that you had to bring jacket to wear inside. i'd frequently freeze after entering a building. i don't know why they do it, because it doesn't make sense. when i did turn on airconditioning at home i'd go barely below 30. just a few degrees cooler than the outside so it feels more comfortable without making the transition to hard.

No they dont. They don't have the money. I remember my childhood when gaming in summer holidays in India, my PC would run at full tilt because my room was at 36C (and outside was 48C).
