When you think about what makes an HVAC system efficient and reliable, you probably picture the outdoor unit, the air handler inside your home, or even the thermostat you adjust every day. But there’s another crucial factor that often gets overlooked—the refrigerant.
Refrigerants are the substances that absorb and release heat as they cycle through your air conditioner or heat pump. Without them, there would be no way to move heat out of your home in the summer or bring it inside during the winter. And not all refrigerants are created equal.
That’s why Daikin, one of the world’s leading HVAC innovators, has chosen R-32 as its refrigerant of choice. At Harbin Heating & Air Conditioning, we install Daikin systems every day across Tennessee and Mississippi, and we’ve seen firsthand why R-32 is a game changer for efficiency, performance, and environmental responsibility.
A Quick History of Refrigerants
To understand why R-32 is important, let’s look at how refrigerants have evolved:
Older systems once relied on CFCs like R-12. These were efficient, but they severely damaged the ozone layer.
HCFCs like R-22 came next. They were better for the ozone, but still harmful to the environment. R-22 was completely phased out in the U.S. in 2020.
HFCs such as R-410A became the standard. They don’t harm the ozone layer, but they do have a high global warming potential (GWP), which means they contribute heavily to climate change.
The industry needed a better option—one that balanced performance, safety, and sustainability. That’s where R-32 comes in.
What Is R-32 Refrigerant?
R-32 is a hydrofluorocarbon (HFC) refrigerant, but unlike older blends, it is a single-component refrigerant. That makes it easier to handle, recycle, and reuse.
It’s also more environmentally friendly. R-32 has a global warming potential of about 675, compared to R-410A’s 2,088. In simple terms, R-32 has about one-third of the environmental impact of the refrigerant most U.S. systems still use today.
This combination of performance and responsibility is why Daikin has embraced R-32 in millions of units worldwide.
Why Daikin Chose R-32
Daikin was the first major manufacturer to bring R-32 to the HVAC market. Their decision wasn’t just about keeping up with new regulations—it was about leading the way.
There are a few main reasons Daikin prefers R-32:
It’s Better for the Environment
R-32 has a much lower global warming potential compared to R-410A. It also doesn’t damage the ozone layer, so homeowners can feel good about making a more sustainable choice.It Improves Efficiency
R-32 transfers heat more effectively, which means systems that use it can run more efficiently. This translates into lower energy use and lower utility bills for homeowners.It’s Easier to Handle
Because R-32 isn’t a blend, technicians don’t have to worry about it separating during recovery or recycling. This makes servicing systems simpler and more effective.It’s Proven Globally
Daikin has already installed millions of R-32 systems around the world, from Japan to Europe to North America. It’s a trusted refrigerant that has been tested in all kinds of climates.
What This Means for Homeowners
At first glance, refrigerant may seem like just a technical detail, but the choice of R-32 directly benefits homeowners.
Lower Bills: Because R-32 systems operate more efficiently, they use less electricity to keep your home comfortable.
Future-Proof Investment: With regulations phasing out higher-GWP refrigerants like R-410A, choosing R-32 now ensures your system stays compliant for years to come.
Smaller Carbon Footprint: By reducing greenhouse gas emissions, R-32 helps make your home more environmentally friendly.
Reliable Comfort: Daikin’s long track record with R-32 means you can count on consistent, high-quality performance.
How R-32 Compares to R-410A
If you’re familiar with HVAC, you’ve probably heard of R-410A. It’s been the standard refrigerant in the U.S. for years. But compared to R-32, it falls short.
R-32 is significantly more efficient, which means your system doesn’t have to work as hard to cool or heat your home. It also carries a much lower global warming potential, making it a smarter environmental choice. And because it’s a single-component refrigerant, it’s easier for technicians to handle and recycle.
In short, R-32 offers everything R-410A does—plus higher efficiency, easier service, and a smaller impact on the planet.
Regulations and the Future of Refrigerants
The American Innovation and Manufacturing (AIM) Act is phasing down the use of high-GWP refrigerants like R-410A in the United States. Over the coming years, manufacturers and homeowners alike will have to transition to alternatives like R-32.
By choosing a Daikin system with R-32 today, you’re not just buying comfort—you’re getting ahead of future regulations. That means your investment is protected, and you won’t be left with outdated equipment in a few years.
Is R-32 Safe?
Safety is always a concern when new technologies are introduced. R-32 is classified as an A2L refrigerant, which means it is mildly flammable. However, Daikin has designed its equipment to meet strict safety standards, and R-32 has been used safely in millions of systems worldwide.
When installed by certified professionals like Harbin Heating & Air Conditioning, R-32 systems are just as safe as those using traditional refrigerants.
