York AC Age

The age of a York AC unit can be determined from the serial number on the label. There are two main styles of serial numbers to determine the age.

In the image above, the serial number reads letter, number, letter, number. The first and second numbers are the last two digits of the year of manufacture. So in the case above, W1L6029995 would be manufactured in 2016.
