More recently Carrier has simplified things using the first four digits of the serial number Example: 3xxxxx = 1963, 4xxxxx = 1964, 5xxxxx = 1965, etc.īeginning in 1970 Carrier began to use a letter followed by a singleĮxample: A1 = January 1971, B2 = February 1972, Information below refers toĬapacity: Commonly found in the last three to five digits of model number, sometimesĠ01 = 1.5 ton, 002 = 2 ton, 003 = 2.5 ton, 004 = 3 ton, 004-5 = 3.5 ton,ġ8xx = 1.5 ton, 24xx = 2 ton, 30xx = 2.5 ton, 36xx = 3 ton, 42xx = 3.5 ton,ġ4xx = 1 ton, 18xx = 1.5 ton, 024 = 2 ton, 030 = 2.5 ton, 036 = 3 ton,Īge: Through the 1960s Carrier used the first digit of the serial number to indicate the Third & fourth digits = Year of manufacture.Ĭarrier has used several different codes at different plants. In subsequent years Bryant simplified its system where, the first two digits of serial Manufacture and the letter following those first two numbers Serial number with the first two digits indicating week of Manufacturers have changed their systems of encoding data over time.Ĭapacity: Look for those elusive two digits in the model number usually (but not always)ĭivisible by 6 and divide by 12 to convert to tons.įrom 1964 through 1979 Bryant encoded age information in the Manufacturer's systems make this easier than others. This number can be elusive, as it is not always exactly divisible by 6. Number that is divisible by 6 and to divide it by 12 to determine the capacity rating in Therefore it is often simple to scan the model number for a two-digit Manufacturers often encode the approximate rating in Btus somewhere in the There are 12,000 Btus per ton of cooling, and air conditioners are sized by every Manufactures in the model number and date of manufacture info in the serial number.
