Around 2000 vacuum-packed insulation (or whatever it is called) went mainstream, resulting in a much better R-value from the same thickness. Add to that more efficient (and quieter) scroll-type compressors.

They can - the coils are on 1 or 2 sides, which leaves 4-5 sides free to be insulated. Each side counts.
