TRANE SERIAL NUMBER LOOKUP
Trane serial number lookup
Find the manufacture date and estimated age of your Trane air conditioner, heat pump, or furnace.
About this lookup
A common modern Trane format places the two-digit year first and the production week next. Older formats differ.
What it supports
Full serials of at least nine characters using the modern year/week prefix from 2010 onward.
If your serial does not match
Older Trane formats are intentionally returned as partial matches rather than guessed.
Where to find the serial number
Check the side or rear of the outdoor unit, inside the furnace door, or on the air-handler cabinet. Copy the complete serial number, not the model number.
