What Homeowners Need to Know About New HVAC Refrigerants in 2025
If you're thinking about replacing your HVAC system or planning ahead, you may start hearing more about “new refrigerants.” These changes are part of a bigger industry shift to make heating and cooling more environmentally friendly—and efficient.
Here’s what you need to know.
Why the Change?
Older refrigerants like R-410A are being phased out because they contribute significantly to climate change. In their place, HVAC systems are starting to use newer refrigerants like R-32 and R-454B, which have a lower global warming potential (GWP).
Benefits for Homeowners
✅ More Eco-Friendly
These new refrigerants help reduce the environmental impact of your home's heating and cooling system—without sacrificing comfort.
✅ Improved Efficiency
Some systems using newer refrigerants operate more efficiently, which could lower your energy bills over time.
✅ Future-Proofing
New HVAC systems are being designed to meet upcoming environmental regulations. Installing a modern system now means you won’t have to upgrade again soon.
Things to Be Aware Of
⚠️ Mild Flammability
Many new refrigerants are “mildly flammable” (labeled A2L). They're safe when properly handled, but this means:
Your contractor must be trained to install and service them safely.
Some homes may need small code updates or ventilation adjustments.
💰 Higher Upfront Cost
Systems using new refrigerants might cost a bit more initially, but the long-term savings and compliance benefits usually make up for it.
Should You Upgrade Now?
If your current system is:
Over 10 years old
Breaking down frequently
Using R-22 (now banned) or R-410A (being phased out)
...then yes—it’s a smart time to upgrade.
Look for ENERGY STAR-rated systems that use newer refrigerants. And be sure your HVAC contractor is familiar with current refrigerant regulations and safe installation practices.
Final Tip
Don’t wait until your system fails. Planning your upgrade now gives you more choices—and helps you stay ahead of future changes in home energy standards.
