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.   
  
  
YORK HVAC DATING (Unitary Products since 1984)   
Note: they skip the letters I, O, Q, U, Z.   
Year of make indicated by 3rd letter in the serial number.   
  
1971 - A 1992 - A   
1972 - B 1993 - B   
1973 - C 1994 - C   
1974 - D 1995 - D   
1975 - E 1996 - E   
1976 - F 1997 - F   
1977 - G 1998 - G   
1978 - H 1999 - H   
1979 - J 2000 - J   
1980 - K 2001 - K   
1981 - L 2002 - L   
1982 ? M 2003-M   
1983 ? N 2004-N   
1984 ? P 2005- P   
1985 - R   
1986 - S   
1987 - T   
1988 - V   
1989 - W   
1990 - X

Hope this helps.
