Their centrifugal chillers are/were pretty good machines. We had three of the old R-11 machines that ran 30 years and were replaced when R-11 became too hard to get.
So you’re left with what, Trane and York?
There are only a few air conditioning manufacturers that make dozens of different brand names. There’s also Lennox and Goodman, but they label many brands, as do Trane and York (and Carrier).

My aircon guy still swears by Carrier. Says he has seen many units that run well for 25 years or more. But he says Trane has gotten better in recent years. Dunno about York.
