Default Unitary age, please

Compressor : S/N 990756798

Air Handler : S/N ( EKHS697737

I believe both indicate 1999?

Thanks

On the air handler...

Unitary, York, Fraser Johnson, Borg-Warner...all the same crowd.

Third letter in the S/N.

1978 - H 1979 - J 1980 - K 1981 - L 1982 – M 1983 – N 1984 – P
1985 – R 1986 – S 1987 – T 1988 – V 1989 – W 1990 – X 1991 – Y
1992 – A 1993 – B 1994 – C 1995 – D 1996 – E 1997 – F 1998 - G

Thanks - seems strange that the compressor and air handler would have different serial number formats.
