When I tell people I have an aircon for the British summer I am often told it is not worth it for the 2 to 3 days of summer we get a year.  We get more than that, and as this year (2022) proves, it's been a very long, very hot, very dry summer.  Aircon is a godsend and while I sleep at night all cool and even with the duvet on, those who can afford them yet poopoo the idea, well, they can continue with their being uncomfortable, too hot and no sleep summer can't they?
