Hi, I’m trying to determine the age of the following Janitrol unit. I’m guessing that it was manufactured in 96’, however, I can’t seem to find anything on their nomenclature on-line. If anyone has any details on Janitrol’s nomenclature and wouldn’t mind sharing, it would be greatly appreciated. Janitrol, Model No. AA1CJ036-C, Serial No. 1296E14228 Also, what would be considered an average life expectancy in the northeast for one of these units? Regards, Steve ---

Hi, Would you mind sharing where you found the information on Janitrol’s nomenclature? I contacted Goodman and they didn’t even recognize the numbering. Thanks, Steve ---

I’m trying to identify the age of a Janitrol Gas Boiler. Serial number is J-20-9389. I know it is definitely not 1989, wondering if it might be 9/38. House built in 1900. ---
