Friedrich age help please

[William E. Siegel]

84EU 2969
84DU 2627

Both of these serial numbers are off Freddrich Heat pump units. The units were built in 1985, so I am thinking that they are 1984, but both units look newer than that. Anyone got a confirmation or know what year these are?

Thanks in advance.

That what I get in my book to 1984

1984. They look newer because you're in Hialeah. I find 1970 units that look like 2000 units because of the weather here.
