Although hugely inefficient in both materials and energy.
Reliability tends to be in opposition to efficiency for mechanical stuff. Yeah, it sucks more energy which is bad, but if you use 50% less stuff for an efficient unit but end up replacing it 4 times while the old one still runs you end up using more materials.
We need a happy medium between as efficient as possible but only last for a few years and reliable but very inefficient.
The flip side is we don’t think about the old ACs that destroyed themselves inside the expected lifetime, we only see the freaks that blast on regardless of damage and just never deteriorate. If the old ones all lasted 50+ years, we wouldn’t see people needing to buy new ones.
It’s still probably the case that older devices without plastic control boards lasted longer, but it’s worth remembering that we only see the edge cases.
Also, some of the old appliances will keep trying to function even when they’ve degraded to the point of being nearly inoperable, where the new device will be able to detect that it’s not working right and shutdown, probably before it’s not worth it to run anymore, but probably in time to be reparable.
Also louder, bigger, noisier

Are you sure old ACs actually worked better, or are you just remembering a time from your childhood when climate change wasn’t as bad and summers were cooler?
I’ve seen frost blow out of older air-conditioning units they would run so cold…
I’ve seen that happen to newer ones. They still freeze up around here if you run them all the time.
I’m not talking freezing up I’m talking putting out 30 degree air after running for 15 minutes… Good job trying to down play the efficiency loss we suffered moving away from horrible refrigerants. We are better for it but the change In Refrigerants was the biggest cause of difference.
Hell i have had snow flakes in a car with older r12 and full on Florida humidity.
