Furnace & AC Age Help

[Thomas Palma]

I'm looking to verify the age of a furnace and AC

I came across a York Furnace and AC in a townhouse built in 2001.
The furnace model P4DNA12N06401A, Serial ECKM061510
My info tells me this was manufactured in 1980. Is this true.

AC also a York. Model H1RA024S06D. Serial WNJM004798
I don't have any info on looking this up.

Any help would be appreciated.

Tom,

Prseton's Guide, says the York Furnace was built between 2000 & 2005. The AC was built between 1996-2005

Thomas,

When there are three or four letters at the start of the serial number, the third letter is the year. Y is 1991, A is 1992, B is 1993, C is 1994, D is 1995, and so on.

Your third letter is K, so this York furnace was manufactured in 2001.

The third letter in the A/C is J, so that was manufactured in 2000.
