If you’ve been shopping for a new air conditioner in 2025, you’ve probably noticed something different on the spec sheets: R-32 refrigerant is showing up everywhere, while the once-standard R-410A is on its way out.
4 Ton Up to 15.2 SEER2 Goodman Air Conditioner Condenser - GLXS4BA4810
Goodman—one of the biggest names in residential HVAC—has already made the switch. But why? And more importantly, what does that mean for homeowners like you?
I’m Mike Sanders, and I’ve been around enough HVAC systems to know that changes in refrigerants can seem confusing. Don’t worry—I’ll break it down into plain English. By the end of this guide, you’ll understand:
-
What refrigerants actually do in your AC system
-
The key differences between R-32 and R-410A
-
Why Goodman made the switch in 2025
-
How it impacts costs, efficiency, and long-term reliability in your home
❄️ First Things First: What Does a Refrigerant Do?
Every air conditioner needs a refrigerant—it’s the chemical that absorbs heat inside your home and releases it outdoors. Without it, your AC is just a big fan.
-
Inside unit (evaporator coil): Refrigerant absorbs heat.
-
Compressor: Pressurizes and circulates refrigerant.
-
Outside unit (condenser): Refrigerant releases heat into the air.
The better the refrigerant is at transferring heat, the more efficient your AC system will be.

🔬 R-410A: The Old Standard
For nearly 20 years, R-410A has been the gold standard in U.S. residential air conditioners. It replaced R-22 (Freon) back in the 2010s because it was safer for the ozone layer.
Pros of R-410A:
-
Non-toxic, non-flammable
-
Reliable performance
-
Widely available
Cons of R-410A:
-
High Global Warming Potential (GWP): Around 2,088
-
Lower efficiency compared to newer refrigerants
-
Being phased down under the AIM Act (American Innovation and Manufacturing Act)
👉 Translation: R-410A works fine, but it’s a “dirtier” refrigerant when it comes to climate impact.

🔄 R-32: The New Kid on the Block
While R-32 isn’t brand new (it’s been used in Asia and Europe for years), it’s only now becoming the U.S. standard.
Pros of R-32:
-
Lower GWP (~675) → about 70% less climate impact than R-410A.
-
Better heat transfer → higher efficiency.
-
Easier to handle (single-component refrigerant, unlike R-410A which is a blend).
-
Future-proof under current regulations.
Cons of R-32:
-
Mildly flammable (classified as A2L), though completely safe in properly designed systems.
-
Not yet as widely available as R-410A—but quickly catching up.

📊 R-32 vs. R-410A: Side-by-Side Comparison
| Feature | R-410A | R-32 |
|---|---|---|
| Global Warming Potential (GWP) | ~2088 | ~675 (≈70% lower) |
| Ozone Depletion Potential | 0 | 0 |
| Efficiency | Good | Better |
| Safety | A1 (non-flammable) | A2L (mildly flammable, but safe in AC use) |
| System Pressure | High | Lower |
| Availability (2025) | Declining | Increasing rapidly |
| Cost of Refrigerant | Rising | Lower long-term |
🌱 Why Goodman Switched in 2025
So, why did Goodman officially start rolling out R-32 systems like the Goodman GLXS4BA4810 4 Ton 14.4 SEER2 condenser? Three reasons:
-
Regulations
-
The U.S. AIM Act mandates a phasedown of high-GWP refrigerants.
-
R-410A is on the chopping block.
-
R-32 meets the new environmental requirements.

-
-
Efficiency
-
R-32 systems run more efficiently thanks to better heat transfer.
-
That translates into lower electric bills for homeowners.
-
-
Future-Proofing
-
R-410A is going to get expensive and harder to source for repairs.
-
Choosing R-32 today ensures serviceability for 10–15 years.
-
💡 How Does This Impact Homeowners?
Here’s where the rubber meets the road—what you’ll actually notice.
-
Lower Energy Bills: Because R-32 systems often hit higher SEER2 ratings, you’ll spend less on cooling.
-
Cheaper Refrigerant: A service call that requires topping off refrigerant will cost less in the long run.
-
Peace of Mind: You won’t have to worry about your system being “outdated” by new refrigerant laws.
-
Environmental Bonus: Your AC has a smaller carbon footprint.
🛠️ What About Servicing and Repairs?
If you’re worried that switching refrigerants means techs won’t know what they’re doing—don’t be.
-
R-32 uses slightly different tools for charging and recovery, but HVAC pros are already trained.
-
Safety measures are in place for the mild flammability classification.
-
Goodman has designed their units with proper airflow and leak-prevention safeguards.
Bottom line: Servicing an R-32 AC feels no different from an R-410A system from the homeowner’s perspective.

⚖️ What If You Already Own an R-410A Unit?
Don’t panic. R-410A isn’t banned overnight—it’s just being phased down.
-
You can still buy refrigerant for service and repairs (though it’ll get pricier).
-
Your unit will still run reliably until end-of-life.
-
But if you’re buying new in 2025? Go with R-32.
📝 Mike’s Homeowner Checklist
Before you decide on your next AC system, ask yourself:
✅ Am I buying new in 2025? → Choose R-32.
✅ Do I want lower long-term costs? → Choose R-32.
✅ Do I already own a working R-410A system? → Keep it until replacement time.
✅ Do I care about rebates or incentives? → Most will favor R-32 and high SEER2 systems.

📉 Cost Comparisons
Let’s talk dollars and cents.
-
New R-32 Goodman condenser (4-ton, 14.4 SEER2): $3,500–$4,500
-
Equivalent R-410A unit (closeout models in 2025): $3,000–$4,000
But here’s the kicker:
-
Refrigerant cost per pound (2025 est.)
-
R-410A: $75–$100/lb (and climbing)
-
R-32: $50–$65/lb
-
Over 10 years, the R-32 unit saves hundreds in energy and maintenance.

🧾 The Bottom Line: R-32 Is the Smart Choice
Goodman’s switch to R-32 isn’t just about regulations—it’s about giving homeowners a system that’s more efficient, less costly to maintain, and built for the future.
If you’re replacing or upgrading your system in 2025, don’t waste money on old stock R-410A units. Go with a Goodman R-32 system and you’ll be covered for the next 15–20 years.
As I tell every homeowner I work with:
“You wouldn’t buy a car that runs on fuel that’s being phased out. Why would you buy an AC system that does?”
