How To Tell Age of Trane HVAC from Serial Number

To determine the age of a Trane HVAC unit from its serial number, you need to understand the format of the serial number. This string combination of letters and numbers usually contains the manufacturing date. But first, you have to know how to read the Trane serial number nomenclature.

Trane serial numbers typically follow a pattern where the manufacturing date is encoded within the first few characters.

This HVAC company started in 1987 with the letter B and skipped a couple of letters during the years. The first letter of the Trane serial number nomenclature gives the year of manufacture, and the next two numbers are the week.

In 2002, they started their serial numbers with the year it was built. In 2002, the first character of the serial number was 2; in 2003, 3, and so on. If your Trane serial number is a 9-digit combination of letters and numbers that starts with a number, then the first number is the year. This company again made changes in the year 2010. The first two digits of the trane serial number lookup age are the year.

There can be variations in serial number formats, especially in older or special models. If the serial number doesn’t seem to fit the standard format, it may be necessary to consult Trane’s customer service or a professional HVAC technician for assistance.

Check the year of ANSI rating elsewhere on the data plate to confirm. If you don’t want to bother with serial number lookup, call a local licensed HVAC contractor. They can give you a fast answer about your Trane’s age.
