this appears to be a newer unit 1 to 2 years but I cant figure it out by the serial number , any help would be appreciated.
This looks better…
L= 1996
"1983 to 2001 - If the serial number starts with a letter, then that is the encoded year. W = 83, X = 84, Y = 85, S = 86, B = 87, C = 88, D = 89, E = 90,
F = 91, G = 92, H = 93, J = 94, K = 95, L = 96, M = 97, N = 98, P = 99, R = 00, Z = 01 "
The unit is in to good of condition to be a 1996, unless it has been in storage for the last 20 years. The AC unit in a 2016
How can I tell the age of a Trane furnace from the serial number?
"Trane: Keeps switching the code. Beginning in 1971, age is a number followed by a letter in the serial number. Example: 1C-xxxx = March 1971, etc…
1980, 1981, 1982 the year is a letter in the 7th place. O = 80, T = 81, U = 82
Beginning 1983 a letter was used in the first position to designate the year followed by the week. W = 83, X = 84, Y = 85, S = 86, B = 87, C = 88, D = 89, E = 90, F = 91, G = 92, H = 93, J = 94, K = 95, L = 96, M = 97, N = 98, P = 99, R = 00, Z = 01. Example: B50632891 = Dec 87
(Beginning around 1987 the date of manufacturer is stamped on the ID plate most of the time.)
Beginning in 2002 the first digit of the serial number is the year followed by the week. Example: 7165RHAIG equals the 16th week of 2007.
(Date of manufacture is on the data plate most of the time, but not always)
Beginning in 1987 they began using alpha codes in their serial numbers to determine year of manufacture. They began with the letter B and skipped a couple of letters during the years… The first letter of the serial number gives the year of manufacture:

I just couldn’t believe that a 20 year furnace could look like it was installed last week. As it turns out the furnace was being used as an air handler for the Central Air. Never used as a furnace until this year when the boiler was removed. Thank You Roy.
Any time.
Also, look in the bottom left corner at the ANS/ANSI #…1993
