How are window air conditioners from the 90s quieter AND better at cooling than units from the 2020s?

I studied this but can’t recall the exact details. In the past they used R-12 which required less pressure. It was banned because it was making a big hole in the Ozone layer.
I think we now use R-32 which is as good but requires more pressure. And that’s probably why new ACs are noisier.

Lighter construction to lower shipping costs, mostly.
The newer coolants also require higher pressures to function, which puts more stress on the components.
R-12 didn't put any holes in the ozone, it's just that a good R-12 system can function for so long that it's not profitable. There's a long story about how the hole in he ozone layer story was foisted on the public. We how have less effective aerosols that are way more expensive and systems that aren't as reliable, intentionally. 🙄

American made and a different coolant?
