—”When we had whole-house Air Conditioning installed nearly 30 years ago...We have the same compressor, have not had to replace it...”
Well, that ruined my day!
My unit only made 27 years!
That said the new unit uses less than one of the kWh running at maximum and ~25% or less on lower loads.
So, after the new biden energy bills, my AC dollar cost is about the same.
“My existing Trane AC sadly died an early death at a very young 27 years.; RIP. I did have the needed R-290(Not the old Texas R-1bbq refrigerant, real R290, no water vapor) to revive it, but then the fan solenoid gave out. And we said our goodbyes.”

I have an 18 year old Trane. I’m hoping to be fortunate like you to have it 27 years or more.
