Let’s be honest: nobody wants to hear “refrigerant” unless it’s on a repair invoice. But if you're planning to invest in a new HVAC system, especially something like the Goodman 3 Ton Horizontal R32 Air Conditioner (GPCH33631), knowing what’s inside that unit matters more than you think.
And that’s where R32 refrigerant comes in.
What Is R32 Refrigerant?
R32, or difluoromethane, is a low-GWP (Global Warming Potential) refrigerant used in many new-generation HVAC systems. It’s quickly becoming the global standard—and for good reason.
Compared to R410A, which is still common in older systems, R32 has:
-
A GWP of 675 vs. R410A’s 2088
-
Higher energy efficiency
-
Lower refrigerant charge per unit
This means fewer emissions, better performance, and lower energy bills. It’s especially well-suited for single-zone ductless systems and horizontal units—like the one in our Goodman GPCH33631.
According to Daikin’s global research, R32 reduces environmental impact by up to 68% compared to R410A. That’s a game changer.
Why R32 Matters for Homeowners
Here’s where I get personal. A few years ago, my summer energy bills were out of control. We had a central system that was doing its best, but it was running on outdated refrigerant and guzzling electricity.
After switching to an R32-based mini split, we saw a 22% drop in energy use over the next year. That’s not just better for the planet—it’s real money back in your pocket.
And it’s not just me. The U.S. Department of Energy has recognized R32 as a safer, more efficient replacement under the Kigali Amendment transition schedule.
Safety Considerations
Yes, R32 is mildly flammable (classified A2L), but it’s been deemed safe for residential use when installed correctly. Manufacturers like Goodman have designed their new horizontal packaged units specifically to meet updated UL and ASHRAE standards.
In fact, ASHRAE’s Position Document supports R32 adoption across a wide range of systems, including in homes like yours and mine.
The Bottom Line: R32 Is the Smart Choice
If you're buying a new system—or replacing an old R410A dinosaur—R32 isn’t just a trend. It’s the industry shift you can benefit from today.
That’s why we recommend units like the Goodman Horizontal 3 Ton Air Conditioner with R32. It gives you the cooling power you need, runs on a cleaner refrigerant, and keeps energy bills under control.
