Understanding the 2025 Refrigerant Change: What R-454B Means for Your HVAC System

Beginning January 1, 2025, the EPA has phased out R-410A refrigerant for new HVAC systems and replacing it with R-454B, a more environmentally friendly option.

Why the Change Is Happening

R-454B has a much lower Global Warming Potential (GWP) than R-410A, making new systems cleaner and more sustainable.

What Homeowners Need to Know

1. Your current R-410A system is still serviceable

You can continue repairing and maintaining it — parts and refrigerant will still be available.

2. R-454B systems are more efficient

New systems are designed to deliver:

• Better cooling performance

• Lower energy consumption

• Improved humidity control (critical in Austin’s climate)

• Quieter operation

3. Repair costs may increase over time

As R-410A becomes less common, refrigerant and parts may become more expensive.

4. Upgrading offers long-term value

If your system is 10–15 years old, upgrading to an R-454B unit can reduce future repair costs and improve efficiency.
