#Btu international serial number decoder how to
Click here for more information on how to know the age of trane from serial number. Any type of major modifications done to the system since it was originally manufactured explained here. How many BTUs the unit produces in thousands.
The next 3 letter represents the product type.2 stands for R-22 and 4 stands for R410A. This number represents the type of refrigerant the unit uses. First letter: The model number starts with 4.Trane uses their model number to identify its use in the HVAC system. Each segment will have assigned a number of letters and digits. Trane model number nomenclature split into several segments. 0 = Service digit (they change these as they do “improvements” on thier stuff).B = Minor design sequence (means nothing other than to the facotory).C = Major development sequence C is standard system, E would be VS motor, P would be high eff system.E = Electric furnace (like they said, heat strips are added in the field, could be anything from 10kw to 25 kw).TW = split component heat pump compatable.The Trane model number is #TWE030C140B0, let’s try to decode this model number: Trane RTU model #SXHEC9040E76AD8D3D01GGNRTXħ= 100% Exhaust w/ statitrac & 15 hp motorġ= UL Approval Trane Tonnage from Model Number Visit our HEATING AND AIR CONDITIONING page for other related blog posts on this subject, or go to the INDEX for a complete listing of all our articles.Trane Model Number Nomenclature Examples of Trane Model NumberĬ: Downflow Economizer and Oversize MotorĪ: Service Digit (i don’t know exactly what this means) Will closing doors reduce my heating and cooling costs?.What are the most common problems with wall/window air conditioners?.Why is my air conditioner not cooling enough?.Why does it take so long to cool a house when an air conditioner has been off for a while?.Why has the thermostat screen gone blank?.

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. 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. RLA is an acronym for Rated Load Amperage, and is what the maximum amperage should be when the condenser up and running. 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. And this is another one that is 3-1/2 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. 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. It will be a number divisible by 6 or 12, and represents the nominal BTU of the system in thousands. Look for the 5th and 6th digit of the model number, or approximately that location.
You can determine the size in tons of your International Comfort HVAC system by examining the model number on the data sticker at the side of the a/c condenser (outdoor unit).
