If you’re shopping for a new AC system in 2025, you’ve probably seen two refrigerants mentioned everywhere: R-410A (the old standard) and R-32 (the new kid on the block).
But what’s the difference, and why does it matter?
Tony — a cost-conscious homeowner who doesn’t want to waste money on old technology — had the same questions before replacing his system. His biggest concerns were:
-
⚡ Efficiency: Will R-32 save me money?
-
🌱 Environment: Why is everyone saying R-410A is “bad”?
-
💵 Cost: Will switching refrigerants drive up installation or maintenance bills?
-
🛠️ Future-proofing: Will I regret buying a system that uses refrigerant being phased out?
This guide answers all of those questions (and more) so you can decide whether a Goodman R-32 system is the right move for your home.
❓ Why Are Refrigerants Changing in 2025?
The HVAC industry is going through one of its biggest transitions in decades. Why? Because of refrigerants.
For years, most residential air conditioners used R-410A. It replaced R-22 (Freon), which was phased out because of ozone depletion. But R-410A isn’t perfect either — it has a very high Global Warming Potential (GWP), meaning if it leaks into the atmosphere, it contributes heavily to climate change.
That’s where R-32 comes in. It has a much lower GWP and is part of the U.S. AIM Act (American Innovation and Manufacturing Act) rollout, which aligns with the global Kigali Amendment. These regulations are phasing down high-GWP HFC refrigerants like R-410A over the next decade.
👉 Bottom line: By 2025, most new systems will ship with R-32 or other low-GWP refrigerants instead of R-410A.

🌱 R-32 vs. R-410A: Environmental Impact
This is the biggest reason for the switch.
-
R-410A GWP: ~2,088
-
R-32 GWP: ~675
That means R-32 has about 67% less global warming impact than R-410A.
In practical terms, if your system ever leaks refrigerant, an R-32 leak will have far less environmental impact than an R-410A leak.
Tony’s take: “I’ve got kids and grandkids. If I can buy a system that’s greener and future-ready, why would I stick with outdated tech?”

⚡ Efficiency & Performance Differences
Environmental benefits aside, how do these refrigerants stack up on efficiency?
Heat Transfer Properties
-
R-32 absorbs and releases heat more efficiently than R-410A.
-
That means systems can cool faster using less energy.
Refrigerant Charge
-
R-32 systems use 20–30% less refrigerant by weight compared to R-410A.
-
Lower charge = reduced cost of refrigerant top-offs.
System Design
Goodman has optimized its 15.2 SEER2 R-32 systems to maximize these benefits, pairing condensers like the GLXS4BA3610 with efficient coils (CHPTA4230C3) for strong cooling and humidity control.
👉 Translation: With R-32, you’re not just helping the planet — you’re cutting your monthly utility bills.

🔧 Safety Considerations
Here’s where a lot of homeowners (and some technicians) get nervous: R-32 is mildly flammable.
Classification
-
R-32 = A2L refrigerant (non-toxic, mildly flammable).
-
R-410A = A1 (non-flammable).
What That Means for You
-
R-32 won’t ignite easily under normal conditions.
-
Special tools, training, and safe handling practices are required for installers.
-
Goodman designs R-32 systems with safeguards (sealed circuits, ventilation, and compliance with updated building codes).
Tony’s perspective: “I asked my installer about flammability. He told me it’s less flammable than my propane grill. That put it into perspective.”

💵 Cost Impact for Homeowners
One of the biggest questions: Will R-32 cost more?
Equipment Costs
-
Initially, R-32 systems may be slightly more expensive because of new designs.
-
But manufacturers like Goodman are pricing them competitively to encourage adoption.
Service Costs
-
R-32 requires less refrigerant, so future top-offs could cost 20–30% less than R-410A.
-
Over time, R-410A will become more expensive as production winds down.
Rebates & Credits
-
Many rebates now require SEER2 efficiency ratings and low-GWP refrigerants.
-
Federal incentives under the DSIRE program can reduce upfront cost.
Tony’s math: “If I save $400 a year on energy bills and $200 on rebates, my R-32 Goodman system pays for itself in 6–7 years. That’s a win.”
🛠️ Maintenance & Compatibility
Here’s the truth: You cannot retrofit an R-410A system to use R-32.
-
The oils and pressures are different.
-
Compressors and coils are designed for specific refrigerants.
So if you buy a new R-410A system in 2025, you’re essentially locking yourself into a refrigerant that will be:
-
❌ More expensive over time
-
❌ Harder to find
-
❌ Out of compliance in new equipment
Tony’s advice: “Why spend thousands on a system that’s already on the way out? Future-proof with R-32.”

📜 Rebates, Incentives & Regulations
The government isn’t just encouraging R-32 — they’re rewarding it.
-
Federal Tax Credits: Tied to high-efficiency, low-GWP refrigerant systems.
-
Utility Rebates: Many utilities now require 15.2 SEER2+ with R-32 for rebates.
-
Regulations: By 2025–2026, most states will restrict sales of new R-410A systems.
Check your state’s rebates in the DSIRE Incentives Database.
