I wish those holes for refrigerant lines in apartments were standard in the US. My apartment in the bay area has no AC and furthermore doesn't allow window units, so I'm stuck with inefficient portable units. I'd love to be able to just put some mini-splits in (and I'd probably still come out ahead over renting a place that comes with central AC).
