Hey folks, Jake Lawson here. If you’ve been poking around The Furnace Outlet wondering whether to go with an R-32 PTAC unit or not, you’re in the right place. I’ve got no time for fluff, so let’s dive right into it: R-32 is still your best bet in 2025. Here's why.
🌟 1. Efficiency You Can Count On
PTAC units using R-32 refrigerant are known for their high energy efficiency ratings. In fact, R-32 systems often outperform older R-410A units in real-world performance. Why?
-
Lower Global Warming Potential (GWP): R-32 clocks in at a GWP of 675, which is about one-third of R-410A.
-
More Efficient Cooling Cycle: It takes less refrigerant charge to get the same cooling effect, which means less power used per hour.
-
Improved Heat Transfer: Helps reduce runtime and electricity usage.
Bottom line: You get better cooling with a smaller environmental footprint and lower monthly bills.
🚧 2. Safety Standards Are Fully Met
One question I get a lot is, "Is R-32 safe?" Fair ask, and here’s the straight answer:
-
Yes, R-32 is classified as A2L, which means it's mildly flammable, but it’s been rigorously tested and is widely approved for residential and light commercial use.
-
UL and ASHRAE approved: As long as it’s installed properly by a certified tech, you're good to go.
-
Smart PTAC design: Manufacturers design R-32 units with leak mitigation and airflow strategies that keep risk minimal.
Want proof? The AREMA R-32 Fact Sheet offers a comprehensive breakdown.
🔒 3. Legal Compliance: R-410A Is Getting Phased Out
Regulations are tightening. Federal guidelines under the AIM Act and state-level rules in places like California are pushing R-410A off the market. That means:
-
You may not be able to install R-410A systems soon.
-
Servicing old units could get expensive due to refrigerant scarcity.
R-32 is already the global go-to. More than 160 million systems worldwide use it. That’s not a trend—that’s the new standard.

🌿 4. Environmentally Responsible Choice
We’re all trying to do better by the planet, right? Choosing R-32 helps:
-
Lower carbon emissions from reduced energy use.
-
Less refrigerant leakage impact due to its lower GWP.
-
More recyclable: Single-component blend makes reclaiming and reusing easier.
Bonus: It qualifies you for more rebates and tax credits. Learn how to save with my guide here.
✅ 5. Jake’s Pro Tip: Look for ENERGY STAR + R-32
Want max value? Look for PTACs that combine ENERGY STAR ratings with R-32 refrigerant. That way you’re not only getting top-notch performance, but you also unlock rebates and utility incentives.

🚀 Final Word: Future-Proof Your Comfort
There’s no shortage of options out there, but if you want a unit that performs well, is legally up to snuff, and doesn’t trash the planet, R-32 is where it’s at.
From hotel owners to homeowners, I recommend making the switch before regulations force your hand.
Got questions? The folks at The Furnace Outlet are always ready to help. I say, go green, go efficient, and stay ahead of the curve.
