Thread: Help finding age of Fraser Johnston Furnace

Hi All -

Can anyone help me determine the age of this Fraser Johnston Furnace? The serial number formats I have looked at do not match this one. Serial #: A140029 . Please see attached pic of Data Plate. Thank you for your help.

That brand was absorbed by York in '78 or '79, so that appliance is at least that old.

Time to upgrade.

Thank you Dom for the reply. That helps me a lot.

From all the sources I've found, the SN format must be prior to 1971. How does that add up with regard to the age of the home?

What is the age of house? The A at beginning could indicate 1971.

Hi Scott,
You may have looked at this site already: manufacture or age of a FRASER JOHNSTON® furnace or other FRASER JOHNSTON® HVAC unit | Building Intelligence Center

This serial number does not show up but they can assist you further if you request it. I use this site constantly to find the age of furnaces and HWH's. Good luck.

See my post on the other thread you started for this. It's likely a 1971.

Thanks everyone. The house is early 70's. I appreciate all the help.

Checking under Unitary Products Group (York), if third letter in Model Number is C, it was manufactured in 1973.
