Carrier Furnace Serial Number Decoder

1. Goodman Furnace Serial Number Decoder
2. Ruud Furnace Serial Number Decoder

The Rheem heat pump condenser has a data plate located on the outside unit that will display the model and serial number. The model number is used by the manufacturer (Rheem) to determine the size in tonnage of the unit. It also has important information like the SEER rating and voltage and phase of the unit. The model number is a coded number that must be decoded by using the Rheem model number decoder which is built-in on the HVAC Decoder App. Rheem also rebrands lots of its product to other names like Ruud, Sure Comfort, and Weather King among other names.

The HVAC Decoder App can decode the Rheem model number along with the rebrand unit in a snap.

• • What is the right MERV number for my air conditioning filter? • What is a return air plenum for a furnace or air conditioning system?
• Serial Number format: L943321238 (This serial number is from an actual furnace). Date of Manufacture: Using the second, third, fourth and fifth digits of the serial number L. 21238 you will find the year and week of manufacture. The second and third digits are the year of manufacture and the fourth and fifth digits are the week.

The HVAC Decoder App does all this for you just enter the model number and get the results.

The Lennox Model number of your unit is the most important information required in determining the correct replacement part you need.

Each individual unit has its own unique model number which is located on the data plate of the unit. Instruction manuals and service manuals which may have come with your unit do not contain the complete model number required to identify replacement parts (except when the installer actually wrote down the complete model number in them). It is essential that you get the complete model number from you HVAC unit when looking for a replacement part to ensure that you get the exact part that you need to make sure that your system is running smoothly and efficiently throughout the year.

In a residential heating and cooling system there are generally three main components which make up the heating and cooling system: the condensing unit (outside unit), the furnace, and the evaporator coil (both are indoor and generally mounted together). Each of these components have their own unique model number.

Furnace Model Number Breakdown

Different parts of the model number mean different things. Take a G26Q3/4-100-1 for instance. It breaks down in the following way:

Series Number

This is the series number; the G meaning gas (Natural or LP).

Unit Capacity

This is the drive or air capacity of the unit. Here the 3/4 indicates a 3 to 4 ton drive. There are 400 CFM (Cubic Feet Per Minute) of airflow per ton of cooling. The capability of air movement of this example furnace is 1200 to 1600 cubic feet per minute of air. This particular unit can be matched with a 3 to 4 ton condensing unit.

BTU Rating

This is the BTU (British Thermal Unit) rating of the furnace in thousands. This furnace has a BTU input of 100,000 BTUs. The actual output of the furnace depends on its efficiency. This particular furnace is 90% efficient so its BTU output would be .90 x 100,000 or 90,000 BTUs.

Revision (Dash) Number

This is the revision number. Better known as the Dash number. This number indicates a slight revision has occurred to the model series not requiring a series change. Model series can have many revisions over the span of their life. You may see revision numbers as high as 14 or even 18. The revision number is very important in repair part identification as a -1 unit may have a different circuit board than a -8 would.

Condensing Unit Model Number Breakdown

Different parts of the model number mean different things. Take a 10AC36-1P for instance. It breaks down in the following way:

Series Number

This is the series number. The 10 indicates this is a 10 SEER unit, the AC stands for air conditioner (as opposed to heat pump, HP).

Tonnage Capacity

This indicates the tonnage capacity of the unit. There are 12,000 BTUs in a ton of refrigeration capacity. The 36 indicates this unit has a BTU capacity of 36,000 BTUs. 36,000 divided by 12,000 equals 3 tons.

Revision (Dash) Number

This is the revision number. Better known as the dash number. This number indicates a slight revision has occurred to the model series not requiring a series change. Model series can have many revisions over the span of their life. You may see revision numbers as high as 14 or even 18. The revision number is very important in repair part identification as a -1 unit may have a different motor than a -8 would.

Phase or Voltage Requirement

The P indicates the phase or voltage the unit requires. P equals single phase 208-230 volt where a Y would equal 3 phase 208-230 volt or you may see a G which equals a 460 volt unit. Note: Rarely will a residential unit have anything other than a P for single phase.

Model numbers have varied over the years but their general breakdown is consistent for the most part.
