How many tons is my Carrier air conditioner or heat pump?

International Comfort Products is headquartered in Lewisburg, TN. They are part of Carrier Corporation, which is a unit of United Technologies Corp. In the serial number, the first letter is the place of manufacturer. The first pair of numbers is the year, and the second pair of numbers is the week. Carrier Chiller Serial Number Decoder South East England - Wikipedia, The Free Encyclopedia The Wealden iron industry in the Weald was the site of the first blast furnace in Britain in 1491, who founded Minimodels in Havant; initially the model cars had been Pilz UK and TUI Travel PLC with TUI Airline Management (the fifth largest European air.
You can determine the “nominal” size of your HVAC system by examining the model number on the data plate at the side of the condenser (outdoor unit). Just like the nominal size of lumber or an air conditioning filter, the exact cooling capacity may be a little more or less than the nominal rating, but it’s close.
For Carrier, you should look for the 7th and 8th digits, or maybe 8th and 9th digits, of the model number. It will be a number divisible by 6 or 12, and represents the nominal BTU of the system in thousands. A ton of air conditioning equals 12,000 BTU, and 48 divided by 12 equals 4, so the data plate below indicates the system is 4 tons.
Here’s a rundown of the range you will encounter: 18 = 1.5 tons, 24 = 2 tons, 30 - 2.5 tons, 36 = 3 tons, 42 = 3.5 tons, 48 = 4 tons, and 60 = 5 tons. And the one below is a 2 ton unit.
. If the condenser is older and has had years of direct sun exposure, the numbers may be faded away, like in the photo below. But the printing is slightly raised and, if you hold a flashlight close to the surface of the data plate and parallel to, often it is possible tease out the numbers.
Model number nomenclature HVAC units are identified by their multiple-character model number that identifies a particular type of unit.

If you are unsure whether you have found the right two numbers, you can double-check it by looking for the “RLA” rating on the data plate. RLA is an acronym for Rated Load Amperage, and is what the maximum amperage should be when the condenser up and running. If you divide the RLA by 6 for older units and 5 or 6 for newer units, you should get a number that approximates (not exactly) the tonnage of the system. Make sure you use RLA and not LRA, Locked Rotor Amperage, which is the surge of amps necessary to overcome inertia and start the system. It averages around five times the RLA.

Have you ever needed to know the size and age of your air conditioning equipment?
Depending on the age and equipment manufacturer the format and content of data on the name plate varies, but typically the tag will allow you to discover some or the entire considerable amount of data listed here.
- Manufacturer: The air conditioning equipment manufacturer. (Carrier, Rheem, Goodman, Trane, etc…)
- Model Number,Serial Number, and Cooling Capacity: sometimes cooling capacity is coded into the model number but on most new units, cooling capacity is stated explicitly. On older equipment the BTUH cooling capacity may be encoded in the model numbers.
COOLING CAPACITYdiscusses how to read the cooling capacity in BTUH or tons from air conditioning or heat pump tags or name plates. The serial number of modern HVAC equipment encodes the year and month of manufactured date.
Serial number formats vary by range of years over which equipment was manufactured, and may vary among countries of manufacture for a given company’s equipment, for example between the U.S. and Canada for Carrier air conditioning equipment.
Example: a Carrier Compressor/Condenser Serial# 1389E54894 on a compressor unit.
Air conditioning equipment age from serial number for the example above, the equipment was made after 1980. The first four digits of the serial number are week and year of manufacture, in this case, week 13 of 1989.
FROM MODEL # – Air conditioning equipment capacity from model number
Example: Carrier A/C Compressor Condenser Model# 38XD12400 (same unit as used for the serial number example above), there is variation in how Carrier assigned these numbers but typically the numbers indicate either tonnage or MBTUH. This example has digits in the 4th and 5th positions (right hand 5 digits), so the rating is in MBTUH for this number and “24” signifies 24 MBTUH or 2 tons of capacity.
