Problem is there is two D’s according to the chart below. 74 or 95.

House was build in 96. Furnace was not original. Brown and older looking. AC much newer so 95 is accurate. The furnance did not look like it was manufactured in 95. Why does York use the same two codes for year?
I’d go with the 95 manuf date for my report, but document the condition and explain that it worked (if it did) but based on it’s condition it will likely need to be replaced in the near future (just to cya).
BTW, You might want to send Russel Ray an e-mail. I don’t know how much he watches the board any more, but he’s got some personal resources that he can draw on to answer something like this.
The estimated useful life for most forced air furnaces is 15 to 20 years. The inspector was unable to determine the age of the furnace. The clients should be aware that this furnace may be near, at, or beyond its useful life and may need replacing at any time. Recommend attempting to determine the furnace’s age (ask property owner or service technician), and budgeting for a replacement if necessary.
I’m simply going with this one. Then I’m calling York tomorrow and ask them why the screwy date system they have. Come on really they couldn’t think of something better? lol
First thing I do is check for an ANCI date on the furnace label, if it has one. This give me an approximate date of manufacture. I can give my client a reasonable age of the unit at the inspection and then later on I’ll look up the ser.#.
