How to determine the date of production/manufacture or age of Tecumseh® HVAC Systems.

The date of production/manufacture or age of Tecumseh® HVAC equipment can be determined from the “Unit Date” located on the data plate along with the serial number.

Example Date of Manufacture styles/formats found:

  • Style 1:     16B0613233714 with a Unit Date B0613

Style 1:   Unit Date:  B0613

The Year of manufacture can be determined by using the last two numerical digits of the Unit Date located on the data tag along with the model # and serial number.  It is assumed (but not confirmed) that the first letter of the “Unit Date” may be the month of manufacture.
