AMERICAN STANDARD SERIAL NUMBER LOOKUP
American Standard serial number lookup
Find the manufacture date and estimated age of your American Standard air conditioner, heat pump, or furnace.
About this lookup
Modern American Standard equipment often shares Trane's year-and-week serial structure. Older equipment needs an era-specific check.
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
Ductless products and older serial formats may not follow this rule.
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.
