Not sure this qualifies. But, an apartment complex near me.
I took out one of the run capacitors from an old through the
wall unit. the date on the cap was 1962. Suggests the entire
AC mighta been from about that age.

I've got a house in Phoenix with the original Goetle AC
package unit
on the roof, 3 ton. The house was built in 1971 so the unit
is 38
years old. The condenser fan was replaced 4 times and an
external
crankcase heater was strapped to it 25 years ago when the
internal one
burned out. Anyone know of any that are older that have
worked as
hard as this unit?
