Carrier, Bryant, Payne, Day & NightRecently (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.
ColemanSerial numbers prior to April 1992=1st two numbers are month, then year, then series.
After April 1992, 1st two numbers are year, then month, then series. Call 905-672-0860 if you get stuck.
Comfortmaker (International Comfort)Uses the first letter for the month (skipping I) and the first two digits are the year.

GoodmanFirst two digits of the serial number are the year. Second two are the month.
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.
PeerlessPrior to 1984 there was not a date code included as part of the serial number. Starting in 1984, there was a four digit date code following the serial number that was month and year. Example - JO-12345-1084, this unit was built in October of 1984. Starting in the year 2000, same idea only it was a six digit date code following the serial number that is year and month. Example - 1234567-200105, this would have been build in May of 2001.
Anything without the addition to the serial number would have been made before 1984 and would require contact with the factory.
Rheem & Rudd WeatherkingSomewhere in the middle of the serial number will be a letter. The following four numbers are the week and year.
TRANEUses alpha codes in their serial numbers to determine year of manufacture. They started this in 1987 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 as follows:
O, A=80(seventh digit) U=82(seventh digit) X=84 S=86 C=88 E=90 G=92 J=94 L=96 N=1998 R=2000
T=81(seventh digit) W=83 Y=85 B=87 D=89 F=91 H=93 K=95 M=97 P=1999 Z=2001
In 2002 they started their serial numbers with the year it was built. In 2002 the first character of the serial number is 2, in 2003, 3 and so on.

AIR CONDITIONING SIZE AND YEAR
OF MANUFACTURE
What year and size is the Air Conditioning system?
Let me show you how YOU the Realtor can determine that on your own.Remember that these dates are NOT installation dates, but they are the manufacture date and typically these dates are close to each other.
First let us understand “Tonnage” is:
Tonnage The unit of measure used in air conditioning to describe the cooling capacity of a system. One ton of cooling is based on the amount of heat needed to melt one ton (2000 lbs.) of ice in a 24 hour period. One ton of cooling is equal to 12,000 Btu/hr.
This size of an Air Conditioning Unit is based up many factors, such as composition of the building, which way it faces, the number of windows, the amount of insulation.....
Basic Principals of Air Conditioning:
The basic principals of the Air Conditioning System used for
How to determine the age and size of the AC unit:
The age or manufacture date of an AC compressor is usually coded under the serial number portion of the data plate that is present on the side of the compressor (Outside AC portion of the AC system)
Carrier
The red boxed area is the Serial Number for this type of unit.The “L” indicates the month of the manufacture.“L” being the 12thletter of the alphabet and the ‘01” being the last 2 numbers of the year, thus meaning this is a December 2001 manufacture date.
This is the area where the data or information from above was obtained.The exterior portion of the AC system called the compressor.
Congratulations on learning how to determine the age of an Air Conditioning Compressor.The air handler’s age is determined much the same way.The air handler is located within the interior of the residence most of the time it is in a closet, garage or attic area.This applies to the MAJORITY of AC units in
How to determine the size (called tonnage) of an Air Conditioning system:
First of all the size of an AC unit is called a ton or tonnage.A recap of tonnage is Tonnage The unit of measure used in air conditioning to describe the cooling capacity of a system. One ton of cooling is based on the amount of heat needed to melt one ton (2000 lbs.) of ice in a 24 hour period. One ton of cooling is equal to 12,000 Btu/hr.
Carrier Model Number
The number to remember is 12,000 BTU’s or more simply 12.If 12,000 BTU’s is equal to 1 (one) ton of AC then 18,000 is equal to 1.5 tons and 24,000 is equal to 2 tons and so on.
Look at the model number (Located on the data plate stamped on the actual side of the compressor) on the compressor and there should be a number divisible by 12.It should start at 18 and not be more than 60 for residential AC units.18 to equal 1.5 tons and 60 to equal 5 tons of cooling.
Look at the model number below and you determine the AC compressor size.
The 36 in the model number in the first picture above it means that the AC compressor is equal to 3 tons of cooling.
Once again, size is very important and detrimental to the proper operational status of an Air Conditioning System.
