The R-410A Phase-Out: What Homeowners Need to Know in 2025

If you own a home with an air conditioning system installed in the last 10–15 years, chances are it uses R-410A refrigerant. But big changes are coming in 2025 that could impact your HVAC system—and your wallet. Here's what you need to know about the R-410A phase-out and how to stay ahead of the curve.

Why Is R-410A Being Phased Out?

R-410A has been the standard refrigerant for residential air conditioners and heat pumps for years. However, it’s being phased out due to its high Global Warming Potential (GWP). In response, the Environmental Protection Agency (EPA) is requiring the HVAC industry to transition to more environmentally friendly options.

At United HVAC, we’re staying ahead of the curve by transitioning to systems that use R-454B, a next-generation refrigerant that offers excellent performance with a much lower environmental impact.

Is R-410A Illegal?

No, R-410A is not illegal—yet. Starting in 2025, manufacturers can no longer produce or import new HVAC systems that use R-410A. However, existing systems using R-410A can still be serviced and maintained.

That said, as supply decreases, the cost of R-410A will likely increase, and repairs involving refrigerant may become more expensive over time.

Can I Keep Using My Current System?

Yes, if your system is still working well, you’re not required to replace it. But now is a smart time to start planning for the future. If your system is over 10 years old or you’ve noticed performance issues, upgrading to a more efficient and eco-friendly system that uses R-454B could save you money in the long run.

What Are the Benefits of Switching to R-454B?

Upgrading to a system with R-454B offers several advantages:

• ✅ Lower Environmental Impact: R-454B has significantly less GWP compared to R-410A

• ✅ Improved Energy Efficiency: Many of the new systems are more efficient and reliable

• ✅ Future-Proofing Your Home: Avoid rising R-410A costs and limited part availability

• ✅ Potential Rebates & Incentives: There may be local or federal incentives for switching to newer refrigerants

How Much Does a System Upgrade Cost?

The cost of upgrading depends on the size of your home and your specific HVAC needs. On average, a full system replacement may range from $8,000 to $12,000, but the long-term savings in energy bills and repair costs can make it a wise investment.
