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?

Goetle's must be pretty good. I have friends in Glendale, AZ whose home was
also built in the early 1970s (maybe 1971). They also have the original
Goetle AC package unit on the roof, 3 ton. We were talking about it last
week, and while their unit has had regular preventive maintenance, the only
service item the unit has required is additional coolant.

Having said that, they've been considering replacing the unit in order to
upgrade to one that is more efficient.

Yeah, I would guess it's SEER must be about a 6. Makes me feel bad
for the tenants. I've almost replaced it a couple times but I've
replaced complete units on two other rentals and those "new" ones have
a hard time lasting more then a decade but this old one keeps on
chugging.
