A Trane Model Number is used to breakdown or differentiate one product in a series from another. Serial numbers are commonly used in many different types of trane product. Letters are sometimes used along with numbers in the coding.

Trane Tonnage from Model Number
- TTP018 = 1-1/2ton
- TTP024 = 2 ton
- TTP030 = 2 1/2 ton
- TTP036 = 3 ton
- TTP042 = 3 1/2 ton
- TTP048 = 4 ton
Example of Trane Model Identification
The Trane model number is #TWE030C140B0, let’s try to decode this model number:
- TW = split component heat pump compatable
- E = Electric furnace (like they said, heat strips are added in the field, could be anything from 10kw to 25 kw)
- 0 = Brazed refrigeration connection
- 30 = 2.5 ton like you mentioned
- C = Major development sequence C is standard system, E would be VS motor, P would be high eff system
- 1 = 220-230/1/60 (electric rating)
- 4 = Accurtron flow control check valve
- 0 = Standard insulation
- B = Minor design sequence (means nothing other than to the facotory)
- 0 = Service digit (they change these as they do “improvements” on thier stuff)
Trane model number nomenclature split into several segments. Each segment will have assigned a number of letters and digits. Trane uses their model number to identify its use in the HVAC system.
How to Decode
- First letter: The model number starts with 4. This number represents the type of refrigerant the unit uses. 2 stands for R-22 and 4 stands for R410A.
- Second letter. T stands for Trane.
- The next 3 letter represents the product type. W stands for split heat pump and T stands for split cooling. The third letter equals the product family. Z = leadership – 2 stage, X = leadership, R = replacement/retail, B = basic, A = light commercial.
- The fifth number is for unit’s Seasonal Energy Efficiency Ratio. A single number represents the SEER: 0 = 10, 1 = 11, 2 = 12, 3 = 13, 4 = 14, 5 = 15, 6 = 16, 7 = 17, 8 = 18, 9 = 19.
- The six letter. Zero indicates the system’s connections are brazed or soldered.
- The seven and eight number indicate tonnage. How many BTUs the unit produces in thousands. For example: 36 = 36,000 BTUs.
- The nine letter represents the age. Any type of major modifications done to the system since it was originally manufactured explained here. Click here for more information on how to know the age of trane from serial number.
- Number ten indicates the power supply voltage. 1 = 200-230/1/60 or 208-230/1/60, 3 = 200-230/3/60, 4 = 460/3/60.
- The position eleven, twelve and thirteen. These numbers represent any secondary function.
- Position fourteen stands for minor design modifications
- The last letter is the unit part’s identifier code.
The Trane Model Identification Number of a product is often featured prominently on the packaging of said product. On the physical product itself, the model number is most commonly found on the front, rear or bottom of the product or in the manual pdf.

How may tons is my Ruud air conditioner or heat pump?
Wednesday, March 20, 2019
You can determine the “nominal” condenser tonnage 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 Ruud, you should look for the second cluster of 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 24 divided by 12 equals 2, so the data plate below indicates the system is 2 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.
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.
