What You Need to Know About New Refrigerants

Big Changes Are Coming to Your Home’s AC System

If you’re thinking about replacing your air conditioner or heat pump, there’s something important you should know: The refrigerant inside your system is changing.

Over the next few years, older refrigerants like R-410A are being phased out across the U.S. in favor of new, more environmentally friendly alternatives. Two of the top contenders are R-32 and R-454B. But what does this mean for you as a homeowner?

Let’s break it all down—without the technical jargon—so you can make the best decision for your home and your budget. If you’re considering an HVAC replacement in Schaumburg, IL, or the surrounding areas, it’s essential to understand these updates to make informed decisions, and On The Mark Heating & Air is here to help!

Why Are Refrigerants Changing?

Traditional refrigerants like R-410A have been found to contribute significantly to climate change. To combat this, the U.S. is transitioning to more environmentally friendly alternatives with lower Global Warming Potential (GWP). By 2025, new HVAC systems will utilize these eco-friendlier refrigerants.

Introducing R-32 and R-454B

Two leading replacements for R-410A are R-32 and R-454B. Here’s a brief comparison:

So Which Refrigerant Is Better for Your Home?

While both refrigerants are more eco-friendly than R-410A, R-32 is coming out on top for several reasons:

✅ Higher Efficiency and Performance

R-32 systems are more energy efficient, which means lower electricity bills over time. They also deliver more cooling power, so your system doesn’t have to work as hard.

✅ Less Refrigerant Required

R-32 needs up to 40% less refrigerant compared to older systems. This helps reduce your system’s environmental footprint and can lower installation costs.

✅ Proven Track Record

More than 160 million R-32 systems have already been installed worldwide. Big manufacturers like Daikin have been using it for years with great success—even in the U.S.

✅ Easier to Maintain

Since it’s a single-component refrigerant, R-32 can be topped off in the field without worrying about performance issues. It’s also easier to clean, reclaim, and reuse, which can save you money in the long run.

Why R-454B May Not Be the Best Fit

While R-454B has a slightly lower GWP, it comes with some trade-offs:

• It’s a blend, which means if there’s a leak, the chemical makeup can change—hurting performance.
• It must be charged only in liquid form, which makes maintenance more complicated.
• It’s currently not widely used in U.S. homes, and there’s less manufacturer support.

A Unique Insight: It’s Not Just About the Refrigerant’s GWP

Most people think the refrigerant with the lowest GWP is automatically the best choice. But here’s what the experts know: Your system’s overall efficiency matters even more.

That’s because indirect emissions (mostly from electricity use) make up over 89% of your system’s total environmental impact. So if you choose a refrigerant like R-32 that helps your system run more efficiently, you’ll actually be helping the environment more than with a slightly lower-GWP option that doesn’t perform as well.

What Should You Do Next?

If your system is working fine, you don’t need to rush out and make a change. But if you’re planning to upgrade your HVAC system soon, it’s worth asking your contractor about R-32-compatible equipment.

A few helpful tips:

• Ask about refrigerant type before buying a new system.
• Make sure your contractor is trained to handle the newer refrigerants.
• Look for Energy Star-rated equipment with R-32 for maximum efficiency.
