Better yet. What is the size of this Lennox AC?
SER 5804L03232
MAN# 13ACC 048 230 01
I see the 48 and thought 4 ton but this is a 2950 sq footer home with a dual zone damper system and one compressor.
Lets go Stros!

Info I copied from this website recently:
HVAC AGE CODES IN SERIAL # INFO
Rheem & Rudd: in the middle of the serial number will be a letter "F" the following four numbers are the week and year.
Carrier, Bryant, Payne, Day & Night: Recently (last 20 years or so) the first four numbers in the serial number represent the week and year. Previously, it was a complex series of letters and single digits. Call 905 672-0860 if you get stuck.
Lennox: Either the first two or second two digits are the year, it varies by era, but most of them actually have a separate sticker somewhere that has the year printed on it. Newer ones are first two equals manufacturing plant #, 2nd two are year and letter in fifth slot is month (A thru M minus I). So 5898G 07568 would be Plant # 58, Year of MFR would be 98 and month would be July.
Amana: BLACKHORSE. B=1971 or 1981. (Of course, now that they've been bought by Goodman, who knows what'll happen.)
Goodman: First two digits of the serial number are the year. Second two are the month.
Btu rating is model number..ie; GMP075-3 (75,000 bonnet input)
Compressor is same :serial # 9709088872 (yr1997 wk 09) Tonnage is model # CK361C The first two numbers after the CK (letters) divided by 12 is tons. ie: 36 div by 12= 3 tons.

Note: they skip the letters I, O, Q, U, Z.

The 048 in the model number indicates it is a 4 ton unit.

Is there a publication that lists all this info? Please email me a link if possible. I don’t get to the message board much lately.
