How do I determine the age of a Trane air conditioner or heat pump?
Friday, July 20, 2018
Unlike other manufacturers that encode the year of manufacture in their serial number, Trane prints it clearly, usually in the upper right of the data plate. Older Trane units have a metal plate that is stamped with their information and, if it is worn or dirty, you might have to wipe off the surface dirt and shine a flashlight across the surface of the plate obliquely to read the date etched into the metal.
If the manufacture date is missing or not legible, there are three ways that the manufacture year may be encoded in the serial number. It may be the first two numbers:
Or only the first number of the serial number:
Or, if the serial number starts with a letter, here is how to translate it:
T = 1981, U = 1982, W = 1983, X = 1984
Y = 1985, S = 1986, B = 1987, C = 1988
D = 1989, E = 1990, F = 1991, G = 1992
H = 1993, J = 1994, K = 1995, L = 1996
M = 1997, N = 1998, P = 1999, R = 2000
So the data plate below indicates the unit was manufactured in 1994, which is also verified at the upper right of the data plate.
