Age of Bryant furnace
Serial: 14A 31496
I've been told it's from 1996 but I've also seen a PDF that says it could be from 1972. My house was built in 1956, sold in 1972 and also sold in 1994 so both years seem possible.
Does anyone have a definate answer?
I vote 1972. Definitely 60s/70s vintage, not 1996. In the later 70s they went to the current serial number configuration. 1296A12345 where 12th week of 1996, made in Indianapolis, 12345 is sequence number.
from 64-79 bryant used a number letter code for week/year
so your unit was made 14week of 1972
after 79 they went to 4 numbers at the start first 2 is the week second 2 are the year
hope this helps
