How can I tell the age of a Coleman or Coleman-Evcon air conditioner or furnace from the serial number?
Wednesday, October 24, 2018
There are four variations of the Coleman and Coleman-Evcon serial numbers. The first one, which was used through 1991, has the year encoded as the second two digits of the serial number. The example shown below was manufactured in 1979.
Beginning in 1992, the first two digits of the serial number indicate the age. If the condition of the unit does not make it clear which two numbers are the right ones to use, look for ANSI or other government standards that the system complies with that have the year of the standard in them. Here’s an example of the later Coleman-Evcon style serial number below, indicating the furnace was manufactured in 1994.
Coleman was acquired by Beacon Capital Corp. in 1990 and the Coleman-Evcon brand created, then the company was purchased by the York/Unitary Products in 1996.
Newer units use the one of the two York serial number systems. Go to our blog post How can I tell the age of a York air conditioner or furnace from the serial number? to see if your serial number matches one of their formats.
Here’s an example of one of the newer Coleman formats below. The second and fourth digits of the serial number A0G659923, which are also the first two numbers, indicates a 2006 year of manufacture.
