How can I tell the age of a Comfort Pack air conditioner or heat pump from the serial number?
Sunday, May 24, 2020
Comort Pack is manufactured by National Comfort Products. The second and third digits of the serial number are encoded to indicate the year of manufacture, based on the listing below:
32 = late 1998, 33 = 1999, 34 = 2000
35 = 2001, 36 = 2002, 43 = 2003
44 = 2005, 46 = 2006, 47 = 2007
48 = 2008, 49 = 2009, 50 = 2010
51 = 2011, 52 = 2012, 53 = 2013
54 = 2014, 55 = 2015, 56 = 2016
57 = 2017, 58 = 2018, 59 = 2019
60 = 2020, 61 = 2021, 62 = 2022
and so forth. So, for example, 34921174 would be 2009
Also, for units built before 9/30/98, the second and third digits after the letter “B" are the actual year of manufacture. So, B96214128 is 1996.
