Age of Unit

Can anyone tell me the age of this A/C unit? It is a LUX AIRE serial number WEKMO28665, Model number HABC-F036SE.

Thanks!!! In advance.

Unit is made by York-Borg Warner ,K in serial mean 2001, get more info from company at(717)771-7890.


Note that the K could also be 1980, so you might need to use other clues (such as construction date of the house) as well.

I find a lot of older units here in San Diego, all the way back to 1968 so far (except for an Octopus from 1938–see the picture at in the HVAC forum), so sometimes these 20-year cycles in the serial numbers don’t play nicely.
