Determining the Age of Your Goodman Air Conditioner Model

If you have a Goodman brand air conditioner or heat pump in your home, you may be wondering “how old is my Goodman air conditioner?” Knowing the approximate age of your system can help you determine when it may need service, repairs, or replacement. This article will provide tips on decoding the model numbers of different Goodman AC units to reveal around what year it was manufactured.

Why Date of Manufacture Matters for HVAC Systems

The installation year for cooling equipment like a Goodman central air conditioner or heat pump provides useful insights into its expected lifespan, efficiency level, refrigerant type, maintenance requirements and more. Most HVAC systems have a typical lifespan of 15-20 years, though well-maintained units can sometimes last over 20 years. Air conditioner efficiency standards have also improved over time, so a 20 year old AC generally uses more energy to produce the same cooling than a comparable new unit.

Knowing an HVAC system’s age also clues homeowners into what refrigerant it may use. This is important since some refrigerants, like R-22, are being phased out due to environmental concerns. The production and import of R-22 already ended in 2020, so recharging an older AC unit using it can be costly or impossible. Lastly, being aware of your Goodman air conditioner’s age allows you to proactively budget for repairs or replacement around when issues may start popping up.

Goodman air conditioning and heat pump model numbers provide useful clues into each product’s history if you know how to crack their alphanumeric codes. Here is an overview of how to interpret model numbers for the most common Goodman equipment:

Air Conditioners and Heat Pumps

Goodman brand central air conditioner and heat pump model numbers follow a basic pattern: G + unit type + tonnage + EE (efficiency) + LL (low-sound) + voltage specifics.

Here’s a breakdown of what each group of characters signifies in a Goodman AC model number:

  • G – Indicates it’s a Goodman branded unit.
  • Unit Type – Second digit denotes cooling type: A = Central AC, H = Heat Pump.
  • Tons – Next 1 or 2 digits reveal cooling/heating capacity in tons. Whole and half-ton units are common.
  • EE – Two digit code for efficiency level, higher is better.
  • LL – “LL” suffix means it’s an extra quiet “Low-Sound” model.
  • Voltage specifics – Single or double letter at end indicates electrical details.

So for example, the model number GSC130481EBA decodes as:

G = Goodman
S = Central Air Conditioner
C = Designed for commercial use 13 = Cooling capacity of 1.3 tons 04 = 14 SEER efficiency rating 81 = Introduced in 1981 E = 230 volt single phase power B = Brass evaporator coils A = R410a refrigerant

Therefore, this unit is a 1981 vintage Goodman 13 SEER commercial 1.5-ton central air conditioner. Checking installation manuals can also verify manufacture dates for some models.

Heat Pumps

The model number conventions for Goodman heat pumps follows the same format. A few things that are good to note for heat pumps is that the 2nd digit denotes its heating and cooling capabilities:

  • S = Heat pump for hot and cold climates
  • T = Heat pump for temperate climates

The letter sequences at the end also indicate performance specifics like:

  • Single, two-stage or variable speed compression
  • Backup electric heat availability
  • Additional cold climate features

So the Goodman SSZ140481 Heat Pump decodes as:

G = Goodman S = Heat pump for cold regions S = Single stage compression Z = R410A refrigerant 14 = 1.5 ton capacity 04 = 14 SEER efficiency
81 = Manufactured in 1981

Air Handlers

Goodman brand residential air handlers typically start with A or T letters. Here’s a quick guide:

A = Air handler often paired with A/C or heat pump T = Designed for mobile homes

The third digit denotes capacity, followed by cabinet dimensions and efficiency rating. So an A60U36A model is explained as:

A = Air handler 60 = ~6 ton capacity
U = Upflow cabinet 36 = Width in inches A = 1.5 tons per minute airflow

Let’s Dial in the Year For Your Goodman AC Unit

Now that you know the basic format of model numbers for Goodman cooling equipment, you can use that information to zero in on the manufacture date for your unit.

The key is focusing on the two digits that precede the voltage and refrigerant codes. These numbers indicate the year a given A/C or heat pump model was introduced by Goodman.

So for example:

81 = 1981 model 06 = 2006 model 19 = 2019 model

It’s reasonable to assume your Goodman unit was built sometime around that date or shortly thereafter.

Subtract the 2-digit year model code from the current year, and you’ll have a pretty good idea of your air conditioner’s age. Let’s take a couple examples:

Goodman Model: GSC130481EBA

Year Code: 81

Current Year: 2023

2023 – 81 = 1942 years old!

So we can safely conclude this A/C unit has seen better days and is ready to retire.

On the other hand:

Goodman Model: GSZ140689CA Year Code: 89
Current Year: 2023

2023 – 89 = 34 years old

While not exactly new, a 34 year old unit could potentially have some useful life left if properly maintained.

Caring for Your Goodman Central Air Conditioner Over Time

Learning “how old is my Goodman air conditioner” is just the first step to getting the most from your cooling equipment. Performing regular maintenance and promptly addressing repairs for your older or newer Goodman product are equally important. Here are some tips:

  • Change filters monthly during cooling season or as needed. Dirty filters strain the system.
  • Clear debris that collects around the outside unit. This allows for proper airflow.
  • Have an HVAC pro annually check refrigerant levels, belts, coils and overall function. This tune-up optimizes efficiency and lifespan.
  • Listen for odd noises, smells or other red flags something may be amiss internally. Schedule service promptly for suspected issues.
  • Compare operating costs on energy bills over time. If rising rapidly despite maintenance, the system’s age could be hindering performance.
  • Consider upgrades like Wifi thermostats or duct optimization for older units lacking smart technology. This maximizes their efficiency.

Know When It’s Time to Say Goodbye

We hope learning the year your Goodman air conditioner entered the scene helps provide clarity on its current status. Keeping aging HVAC equipment well maintained is wise, but be realistic. Once an AC unit passes roughly 20 years old, repair expenses accelerate while energy efficiency declines. Replacement with a properly sized modern unit is often smarter financially and environmentally when systems grow really dated. And upgrading prior to emergency breakdowns in very hot or cold weather is far less stressful!


The serial number on your Goodman branded air conditioning unit, heat pump or complimentary system components holds valuable insights into its origins if you crack the code. Checking when your model first came out reveals approximates of current equipment age. This empowers homeowners to make informed decisions regarding maintenance, upgrades or replacement. We hope this guide to decoding Goodman model numbers provides clarity on the best path forward with your home’s cooling and heating needs. Don’t hesitate to contact a professional for a second opinion as well on your Goodman product’s status. With proper care, even aging HVAC equipment can safely deliver comfort to your household for years to come.
