HVAC manufacturers often code their unit specifications into multiple-character model numbers. Goodman air conditioner model number is an example.In this article, I will explain in detail the Goodman model number, where the location is, and how to read the numbers.
The Goodman model number nomenclature and styles is vary between models. I will give an example of how to decode some styles of the model number and where it is located.
Where is the model number on a Goodman?
The Goodman model number can be found on a data tag located on the rating plate of your air conditioner, heat pump or furnace. Look at a slightly above the refrigerant valves on the back side of the A/C unit as show on the picture below.
The Goodman model number is made up of a series of letters and numbers that tell what kind of furnace it is.
The serial number is different from the model number. The Goodman serial number is a ten-digit code that tells us when the unit was made, what model it is, and a lot of the parts that went into making it. If you can’t get to the sticler plate, look for the model number in the instructions or other paperwork that came with the unit.
How do you read Goodman model numbers?
Goodman Air Conditioner model number is 12 digit code. If you decode the model number, you can figure out how many tons your Goodman HVAC system is.
The model number includes the nominal cooling capacity in three digits beginning with zero. This three-digit number is the unit’s capacity measured in British Thermal Units.
For example, “048” indicates 48,000 BTUs. To calculate tonnage, divide the BTUs by 12,000, which is the weight of one refrigeration ton. For example, an unit with 48,000 BTUs has a tonnage of 4.
Example of Goodman Model Number
- D = is for Brand (Goodman)
- S = is for Product Category (Split System)
- X = is for Unit Type (Condenser R410A)
- C = is for Feature (ComfortNet)
- 18 = is for Efficiency Rating (18 SEER)
- 048 = is for Nominal Capacity (4 Tons)
- 1 = is for Electrical
- A = is for Major Changes
- A = is for Minor Changes
How do you tell the tonnage of a model number?
British thermal units (BTU) per hour are used to measure heating and cooling power. It is the amount of heat needed to make one pound of water one degree hotter. Tonnage is used to describe the cooling capacity of an air conditioner.
When it comes to locating the Goodman ac size, finding the tonnage is the crucial part. There are numbers that you need to take attention to find the size or tonnage.
- 18 = 1.5 tons
- 24 = 2 tons
- 30 = 2.5 tons
- 36 = 3 tons
- 42 = 3.5 tons
- 48 = 4 tons
- 60 = 5 tons
Whether you’re buying an air conditioner for the first time or want to replace your old one, the first thing you might look at is the tonnage. Most people find it hard to figure out the Goodman AC tonnage.
We hope this article helps you understand finding AC tonnage from the model number.
