AC Model Numbers

When your air conditioner is not working properly, you will want to know what type of air conditioner you have. Most people do not know this information, especially if it has been a while since they bought the air conditioner or had it serviced. Cousin's Air, Inc. has NATE-certified service professionals that are friendly, knowledgeable, and can help you figure out what air conditioner you have by using the model number decoder. There isn’t a universal model number decoder since AC manufacturers uses different codes, but the model number can tell you the capacity, tonnage, single/variable speed, voltage, refrigerant type, and brand name of your air conditioner. Once we know what type of air conditioner you have, our expertly trained team of technicians will be able to diagnose and fix your problem.

How Can You Decode the Model Number on Air Conditioners?

Air conditioner manufacturers usually list how to decode the model number so that you will be able to know what type of coolant or refrigerant it takes, what size air filters it needs, and how much replacement parts are. You can also use the tonnage to figure out how much energy your air conditioner uses in BTUs and kilowatt hours.

Here is an example of a Trane brand air conditioner and how to use its air conditioner model decoder:

How Do I Read My AC Model Number?

Let's look at a Trane brand air conditioner as an example.

Capacity: Trane has used a number of different methods for encoding capacity information in the model number. It is commonly found in the first three digits – sometimes as BTUs and sometimes as tons.

Example:

• SPCC-B504-A = 5.0 ton, or
• TWS748A = 48,000 BTU = 4 ton

Age: For units manufactured up through the 1970’s, the date of manufacture information is found as a number and a letter in the serial number where the number is the single digit year and the letter indicates the month. A=Jan, B=Feb, C=Mar and so on.

Example:

• 1C-xxxx = March 1971
