A/C in these cars never worked all that well, it was a factory version of an add-on system. Nothing like the systems in the current cars. And it drained significant engine power. An old joke was that acceleration and a/c were mutually exclusive. For a while there was an add-on device available that cut the a/c compressor during acceleration. And it uses the old freon, which isn't readily available anymore. So I'm guessing that a combination of these reasons resulted in a former owner simply removing it.

Don't add the AC. It doesn't work well at all and drains probably 10-15% of the power from the engine (which didn't have more than 110hp when it was new anyway).

I haven't used mine in years and when it did work, I'd only use it when someone else was in the car with me who was not used to driving with no a/c in Georgia summers
