Thread: Age of Carrier brand evaporator

Can any of you guys help me with age of Carrier brand evaporator. I can decode most condenser serial numbers but cannot decode this evaporator number. Serial number is written in ink on cabinet. Any help appreciated. See photo.

Gene,
Beginning in the 1970, Carrier began to use a letter followed by a single digit year.
Example: A1 = Jan 1971
More recently Carrier has simplified things using the first four digits in ser# to signify age, where first two digits indicate week and third and fourth indicate year of manufacture.

May be July 1970 Does the unit appear older?

Hi James, thanks. The unit did not "appear" to be a 70s vintage, maybe late 80's or early 90's vintage, but hey, I have been fooled before by trying to guess the age. The condenser it was matched up with was a 1993 model. This unit was in a home built in 1959.

Thanks

Maybe they transposed a few numbers in the ser#! I would propably state that the age of evap could not be determined!

Yes, good thought. Thanks.
