How to Read American Standard Furnace Model Numbers

If you already have an American Standard furnace and want to learn several details about it, checking it out and decoding the model numbers is a good starting point. American Standard, just like any other respectable manufacturer, will use serial numbers to identify a particular production run for a model.

How to read American Standard Furnace model numbers

Several furnaces (hundreds or even thousands) from American Standard will have the same model number. The serial number, though found on your furnace, is unique to your furnace. When you try to find the furnace’s parts diagram, you will see serial numbers listed in the range for model numbers. The model number refers to a particular kind of furnace made by the manufacturer, whereas the serial number is specific to your furnace.

Model numbers stay the same, whereas serial numbers don’t

Every furnace in a model number of products run is unique because it’s often that the manufacturer will make the same furnace for many years. With American Standard, it’s understandable why the same furnace model is mass-produced every year. However, when the manufacturer plans to make the same model five years later, it will want to make improvements as technology progresses. Newer and better components would be available five years after the first production.

In such a case, many of the model number’s components stay the same, while other parts are replaced with newer and better alternatives that weren’t available five years ago.

When you need to service your American Standard furnace, you will need the model and the serial number to find replacement parts.

Why are the model and serial numbers important

When a manufacturer uses the model and serial number, he eliminates errors and avoids the message “Item not found.” As we’ve mentioned, manufacturers change the parts they’ve used on the assembly line for various reasons.

Here’s how to read the model number on your American Standard furnace:

T- is the brand identifier and can be A (American Standard) or T (Trane)

U- is the furnace configuration and can be:

  • U- Upflow /Horizontal
  • D- Downflow/Horizontal

Y- type:

  • C = Condensing
  • D = Induced Draft
  • E = Electronic Ignition
  • X = Direct Vent Condensing
  • Y = Direct Vent Condensing Variable Speed

080- Heating Input (mbtu/h)

R-Major Design Change

  • C = Single Stage
  • R = Two-Stage
  • All other = Standard system

9- power supply and fuel

  • 115V
  • Natural gas

V3- Airflow Capacity for Cooling (400 CFM/Ton)

  • 3 = 3 Tons V3 = 1½-3 Tons, Variable Speed Motor (ICM
  • V4 = 2 – 4 Tons, Variable Speed Motor (ICM)
  • V5 = 3 – 5 Tons, Variable Speed Motor (ICM)

V- Minor design change

  • H = Upflow/ Horizontal
  • V = Variable Speed Motor

0-service digit
