How can I tell the age of a Cumberland air conditioner or furnace from the serial number?
Saturday, June 23, 2018
Cumberland was a brand manufactured by American Standard, and followed the Trane/American Standard serial number code format: first letter of serial number indicates year of manufacture. This brand is no longer offered, as far as we know.
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 serial number of the data plate shown below indicates that the unit was manufactured in 1995.
Additionally, the date of manufacture is noted in the upper right of the data plate. Also, see our blog post How many tons is my Cumberland air conditioner or heat pump? For the age of another brand or manufacturer, go to our blog post How do I determine the age of my air conditioner?
