New R-454B AC Refrigerant Change In 2025

Home > New R-454B AC Refrigerant Change In 2025

What Houston Homeowners Need To Know

As of 2025, the air conditioning industry is officially in a new era — and many Houston homeowners are starting to feel the effects. The EPA’s refrigerant regulations have kicked in, which means most new AC systems now use R-454B refrigerant instead of the older R-410A (sometimes called Freon).

At House Pro Air Conditioning, we’ve been getting a lot of calls from Houston homeowners with questions like:

Let’s break down what the 2025 refrigerant change means for you and your home AC system here in Houston.

Why Did AC Refrigerant Change To R-454B?

The short answer? Environmental regulations.

R-410A refrigerant, commonly used in home AC systems for the past 20+ years, has a higher Global Warming Potential (GWP) than the new R-454B refrigerant. As part of a national phase-down of older refrigerants, AC manufacturers are now required to produce new systems that use the more environmentally-friendly R-454B.

Here in Houston — where surviving the brutal summer heat requires reliable AC — this change affects homeowners in a few important ways.

If I Live In Houston, What Does This Mean For My Current AC?

1. You Don’t Have To Replace Your AC Right Away

If your current AC system uses R-410A, it’s still perfectly legal to use and repair — for now. However, this refrigerant change will impact repair costs and future decisions.

2. Freon Prices Are Already Going Up

As supplies of R-410A dwindle, the cost of an AC freon recharge is rising — especially during peak demand in hot, humid Houston summers.

3. AC Refrigerant Leaks Are More Expensive

If your system develops an AC refrigerant leak, repairs will cost more because R-410A is becoming harder to source.

4. R-410A and R-454B Are Not Interchangeable

R-454B refrigerant cannot be used in older R-410A systems. If you’re installing a new AC unit in 2025 or beyond, it will likely use R-454B.

Should Houston Homeowners Repair Or Replace Their AC In 2025?

If your AC is 10-15 years old or you’ve dealt with multiple refrigerant leaks, it may be more cost-effective in the long run to upgrade to a new R-454B system. But if your current system is in good condition, repairs are still an option — just know that freon costs will continue to rise.
