👋 Introduction: My First Question About Refrigerants
Hey folks, Mike Sanders here. When I replaced my old AC system a while back, I noticed something new on the spec sheet: R-32 refrigerant instead of the R-410A I’d heard about for years.
I asked myself: Why did Goodman switch refrigerants? Was this just another industry change to squeeze money out of homeowners, or did it actually make sense?
Turns out, there’s a very real reason. Refrigerants aren’t just fancy chemicals in your AC — they’re the lifeblood of the cooling cycle. And the difference between R-410A and R-32 has a big impact on efficiency, environmental safety, and even your future repair costs.
So let’s break this down in plain English.
❄️ 1. What Refrigerant Actually Does
Before comparing, let’s keep it simple. Refrigerant is the working fluid in your AC system. It cycles between liquid and gas, absorbing heat from inside your home and releasing it outside.
Without refrigerant, your AC is just a big fan moving air around.
Different refrigerants have different properties:
-
How well they transfer heat.
-
How much energy they use.
-
Their safety profile.
-
Their impact on the environment.
That’s why the refrigerant in your system matters more than you might think.
🔄 2. R-410A: The Old Standard
Back in the 1990s, the industry phased out R-22 (Freon) because it damaged the ozone layer. Enter R-410A.
-
Pros:
-
Non-ozone-depleting.
-
Good cooling efficiency.
-
Safe for residential use (classified A1: non-flammable, non-toxic).
-
-
Cons:
-
High Global Warming Potential (GWP ≈ 2,088).
-
Requires more refrigerant per system.
-
Harder to recycle responsibly.
-
R-410A served us well, but the environmental downside was too big to ignore. Under international agreements like the Kigali Amendment and U.S. laws like the AIM Act, R-410A is being phased down.
🌱 3. R-32: The New Standard
Here’s where R-32 comes in. Goodman, along with many other manufacturers, is adopting R-32 as the refrigerant of choice.
-
Lower GWP: About 675 — that’s one-third the impact of R-410A.
-
Better Efficiency: Transfers heat more effectively, meaning lower energy use.
-
Less Refrigerant Needed: Systems require less charge to do the same job.
-
Global Use: Already widely adopted in Asia and Europe.
The only catch? R-32 is classified A2L — mildly flammable. That sounds scarier than it is. In practice, with proper installation, it’s completely safe for home use. (ASHRAE Refrigerant Safety)
🔍 4. Key Differences: R-32 vs. R-410A
Here’s a simple chart for homeowners:
| Feature | R-410A | R-32 |
|---|---|---|
| Global Warming Potential (GWP) | ~2,088 | ~675 |
| Ozone Depletion Potential | 0 | 0 |
| Efficiency | Good | Better |
| Charge Amount | Higher | Lower |
| Safety | A1 (non-flammable) | A2L (mildly flammable) |
| Phase-out Status | Phasing down | Long-term replacement |
Bottom line: R-32 is cleaner, more efficient, and more future-proof than R-410A.
⚡ 5. What This Means for Homeowners
So, what’s in it for you when Goodman uses R-32 instead of R-410A?
-
Lower Bills: R-32 systems use less energy, so you pay less each month.
-
Future-Proofing: R-410A will get harder and more expensive to service as supplies shrink.
-
Peace of Mind: You won’t need to retrofit or replace your system early.
-
Eco-Friendly: Lower environmental impact without sacrificing comfort.
💵 6. Does the Switch Affect Costs?
Some homeowners worry: does a new refrigerant mean higher prices?
Here’s the reality:
-
Upfront Costs: R-32 units may be slightly more expensive due to newer technology.
-
Service Costs: R-410A refrigerant is already climbing in price as it phases down. R-32 will be cheaper and easier to source in the long run.
-
Operating Costs: Thanks to better efficiency, your utility bills are lower.
Over a 10–15 year lifespan, an R-32 system saves hundreds to thousands of dollars compared to keeping an older R-410A. (Energy Star – Cooling Efficiency)
🚨 7. Safety Questions About R-32
Let’s tackle the elephant in the room: flammability.
-
R-32 is A2L: mildly flammable.
-
It won’t ignite under normal operation.
-
Installers are trained to follow proper ventilation and safety codes.
-
In fact, millions of R-32 units have been safely running worldwide for years.
For everyday use, R-32 is just as safe as R-410A — as long as you hire a licensed, professional installer.
✅ 8. Mike’s Takeaway After Switching
When I switched to my Goodman 3 Ton R-32 system, here’s what I noticed:
-
Quieter operation: The system seemed smoother.
-
Lower bills: My summer electricity bill dropped by about 10–15%.
-
Cooler comfort: The house cooled faster and stayed more even.
-
Peace of mind: I knew I wouldn’t be stuck with outdated refrigerant in a few years.
At first, I was skeptical about “mildly flammable,” but after learning the facts and talking to my installer, I realized R-32 is perfectly safe.
📅 9. What’s Next for Refrigerants
The U.S. is committed to reducing HFCs (like R-410A) by 85% over the next 15 years. That means:
-
R-410A will get scarce and expensive.
-
R-32 will become the dominant refrigerant.
-
Future systems may even use blends, but R-32 is the stepping stone.
By choosing R-32 now, you’re ahead of the curve — and you won’t get stuck with a system that’s difficult to service.

🏁 Conclusion: Why Goodman Switched — and Why You Should Care
The move from R-410A to R-32 isn’t just industry hype. It’s a smart, science-backed change that:
-
Saves homeowners money through better efficiency.
-
Reduces environmental impact with a lower GWP.
-
Keeps your system future-proof as R-410A phases out.
-
Provides the same cooling comfort, with safety baked in.
For me, switching to Goodman’s R-32 system wasn’t just about upgrading my AC. It was about making sure my home comfort was reliable, efficient, and ready for the future.
So the next time you see “R-32” on a spec sheet, you’ll know exactly what it means — and why it’s good news for your wallet and the planet.
