These minisplit units are typically, at least 9k to 12k BTUs, and if it a multi-zone unit it can be 24k or more.

I have yet to see a portable AC in the US that is more than 12k btus and as quiet as a mini-split.

Mini-splits are more popular now in the US, but, for whatever reason, the US is really into ducted systems.

I never understood why putting an air duct in a hot attic and an air handler in a hot garage made any sense.

You do have me curious on traffic stats for HN by country, though.

A lot of central AC installations in the USA were added to the house some time after it was built, and the heating ducts were already there, so now they are used as the AC ducts too.

Do you have any more info about this?

I am curious about the history of residential HVAC in the US.
