Introduction
Let’s talk refrigerants. They’re the unsung heroes of your heating and cooling system—quietly doing their job in the background, keeping your home comfortable through every season. But not all refrigerants are created equal. And right now, R-32 is leading the charge into the future.
I'm Jake Lawson. I've been on job sites long enough to remember when R-22 was the standard, R-410A was the “new thing,” and now R-32 is taking over—and for good reason.
If you're shopping for a new 80,000 BTU gas furnace—especially from a collection like The Furnace Outlet’s R-32 Gas Furnaces—you’ll want to know how this refrigerant fits into the picture, why it matters for your HVAC setup, and what the switch to R-32 means for your wallet, your home, and the environment.
Let’s break it all down.
What Is R-32?
R-32, or difluoromethane, is a low-GWP (Global Warming Potential) refrigerant used in many new air conditioning and heat pump systems. It’s part of the next generation of refrigerants that aim to reduce environmental impact without sacrificing performance.
Technically, R-32 is a pure, single-component refrigerant that’s non-ozone depleting and classified as A2L—meaning it’s mildly flammable but very safe when handled correctly in residential applications.
It’s already widely used in Europe, Japan, and Australia. And now, the U.S. HVAC industry is catching up fast, thanks to upcoming regulatory shifts and growing consumer demand for eco-friendly alternatives.
Why R-32 Is Better Than R-410A
If you’re like most folks, you probably think all refrigerants are pretty much the same. Not so. Here's how R-32 stacks up against the outgoing favorite, R-410A:
| Feature | R-410A | R-32 |
|---|---|---|
| Global Warming Potential (GWP) | 2,088 | 675 (70% lower) |
| Efficiency | Good | Higher |
| Ozone Depletion | None | None |
| Flammability Rating | A1 (non-flammable) | A2L (mildly flammable) |
| Recyclability | Blend (harder) | Single substance (easier) |
According to Daikin’s Global R-32 Initiative, switching to R-32 can reduce greenhouse gas emissions by up to 76% when compared to legacy refrigerants over a system's life cycle. That’s not just marketing spin—that’s real impact.
Environmental Regulations Are Driving the Change
The phase-down of high-GWP refrigerants is already happening. The American Innovation and Manufacturing (AIM) Act mandates a national phasedown of hydrofluorocarbons (HFCs), including R-410A. Manufacturers are required to reduce their HFC production and consumption by 85% by 2036.
That means R-410A is on its way out, and R-32 is becoming the new baseline. Many HVAC manufacturers, including Goodman and Daikin, are already integrating R-32 into their next-generation systems to get ahead of the curve.
Bottom line: If you're shopping for a new system today, you’d be smart to future-proof your home by investing in an R-32-compatible system now.
Performance Benefits of R-32 in HVAC Systems
Here’s what really gets me excited about R-32—it doesn’t just help the environment; it performs better in real-world HVAC systems.
✅ Higher Efficiency
R-32 has superior heat transfer characteristics compared to R-410A, which allows systems to run more efficiently. This can result in lower electricity use, which means you save money on cooling costs over time.
The Air Conditioning, Heating, and Refrigeration Institute (AHRI) confirms that systems using R-32 often meet higher energy standards, including newer SEER2 efficiency ratings.
✅ Easier Servicing and Lower Charge Volumes
Since R-32 is a single-component refrigerant, technicians can recover, reuse, and recharge it more easily compared to blended refrigerants like R-410A. It also requires less volume per charge, making systems smaller and lighter without sacrificing performance.
✅ Reduced Greenhouse Gas Emissions
This one’s huge: with a GWP of just 675, R-32 is one of the lowest-impact HFCs still available on the market. When installed and maintained properly, it reduces total greenhouse gas output dramatically over the lifetime of your system.
Safety Concerns? Let’s Clear That Up
R-32 is technically rated as A2L under ASHRAE classifications, meaning it’s mildly flammable. That might make some folks nervous, but here’s the deal:
-
It's not explosive like propane or natural gas.
-
It won’t ignite under normal HVAC operating conditions.
-
Manufacturers now build systems with safety shutoffs and sensors to comply with updated UL 60335-2-40 standards.
-
Most of the concern is industry-side, not homeowner risk.
The Environmental Defense Fund supports the shift to A2L refrigerants like R-32, citing a positive climate trade-off with negligible residential safety risk.
R-32 in Heating: What’s the Connection to Gas Furnaces?
Now let’s tie this back to gas furnaces, particularly 80,000 BTU models.
While gas furnaces themselves don’t use refrigerants, many are paired with:
-
Air conditioners
-
Heat pumps
-
Packaged HVAC units that do include refrigerant loops
If you’re buying a gas furnace system, it’s important to consider R-32 compatibility across your entire HVAC setup. Buying a non-compatible A/C system today means you might be stuck with obsolete refrigerant tech sooner than you think.
That’s why the team at The Furnace Outlet is making sure every gas furnace system they sell in this line is designed to work seamlessly with R-32-based cooling units.
Should You Upgrade Now or Wait?
Some folks are still on the fence—waiting for “the next big thing” or unsure if R-32 is just another transition phase. Here’s what I tell my clients:
If you’re upgrading any part of your HVAC system in the next 1–3 years, do it now with R-32-compatible gear. Why?
-
Prices will only go up as demand increases.
-
R-410A is already becoming harder (and more expensive) to source.
-
You’ll future-proof your home and avoid being stuck with outdated equipment.
Plus, utility companies and green incentive programs often offer rebates for R-32 and high-efficiency equipment installs. The Database of State Incentives for Renewables & Efficiency (DSIRE) is the best place to check what’s available in your area.
