There is no standard format for how the letters and numbers are used. trane heating and air conditioning companies are free to decide how they want to use the package unit model number.
Examples of Trane Model Number
The Trane model is #TCD120C40CCA
TC: Package Cooling, Electric Heat

120: 10 Tons, Standard Efficiency
C: Major Design Sequence
4: 460/60/3
0: ? (a description is not listed)
C: Downflow Economizer and Oversize Motor
C: Minor Design Sequence
A: Service Digit (i don’t know exactly what this means)

H= Single Zone
E= 5th Developement sequence
C90= 90 Tons
4= 460/60/3 XL
0= No Heat
E= Design Sequence
7= 100% Exhaust w/ statitrac & 15 hp motor
6= Ex fan Drive 600 RPM

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.
