Unitary age, please

Compressor : S/N 990756798

Air Handler : S/N (8) EKHS697737

I believe both indicate 1999?

Thanks

On the air handler…

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

H is 1999. You are sooooo right!

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