Where to Find the American Standard Furnace Serial Number
The serial number of an American Standard furnace is typically located on a metal data plate attached to the inside of the furnace cabinet. This plate is often found near the blower compartment or on the heat exchanger cover panel. The serial number is usually next to the model number and includes other vital information such as electrical specifications and safety certifications.
For easy identification, remove the front panel of your furnace carefully to locate this tag. Avoid tampering with electrical components to ensure safety.
How to Decode the Serial Number to Find Furnace Age
American Standard serial numbers contain coded information about the furnace’s manufacture date. These serial numbers usually consist of 10 to 12 characters featuring letters and numbers. The key to determining the furnace age lies within specific positions in this code:
- Early models (pre-1990s): The first two digits often specify the year.
- 1990s to early 2000s models: The third and fourth digits typically indicate the month and year, or the first four digits may reflect the date code.
- Recent models: The serial number may use a different coding format; consult specific manufacturer resources or contact American Standard customer service.
For example, a serial number starting with 061720A1234 might decode as June 17, 2020.
Common Serial Number Formats for American Standard Furnaces
Understanding the variations in serial number formatting aids in identifying the furnace age. Here are typical formats used over different production decades:
| Period | Serial Number Format | Decoding Method |
|---|---|---|
| 1980s | YYMMXXXXXX | First two digits = Year, next two digits = Month |
| 1990 to Early 2000s | MMYYXXXXX or YYMMXXXXX | Month and Year embedded in first four digits |
| Recent Models | Varies; may include letters and numbers | Check American Standard’s official resources or contact support |
