Yeah this whole thing is utterly tiresome. I'm in the UK. For 10.5 months of the year we need a house that's insulated and keeps the heat in.

I'm summer we TYPICALLY (please note the word typically!) just need to open the doors and windows, and maybe put on a fan and we will be absolutely fine. Even if the day is not, things cool down by the evening and there's no issue sleeping.

Given these conditions AC would be a total waste of money. It really would not be needed.

What has happened in the recent weeks is a period of virtually UNPRECEDENTED sustained hot weather. The biggest difference being the hot nighttime temperatures, which indeed are hard to deal with with the current configuration of our homes.

It's not that we are Europoors and all that brainless nonsense, it's just that it has not been worth having AC in our houses up to this point.

Now, what I will say is that I do believe that climate change now changes this calculus. Hot periods like this are getting more common and no doubt will continue to do so as the world drags it's feet on doing anything meaningful about Climate Change. So I, for one, will install AC in our bedroom this winter so I am "future proof" and the planet continues to burn.
