2025 HVAC Refrigerant Change
The 2025 HVAC Refrigerant Change: What You Need To Know
The HVAC industry is set for a big shift in 2025 as the Environmental Protection Agency (EPA) phases down the use of certain refrigerants. Along with this change, manufacturers are expecting equipment prices to rise 10-30%, making it even more important to plan for any upgrades.
If you’re unsure about what this means for you, don’t worry - this guide will explain the new requirements and help you prepare for the 2025 HVAC refrigerant change.
What Is the 2025 HVAC Refrigerant Change?
While air conditioners might not seem like major polluters, the refrigerants they use can have a significant impact on the environment. Many older units contain hydrofluorocarbons (HFCs) and chlorofluorocarbons (CFCs), both of which contribute to global warming.
To address this, the EPA passed the American Innovation and Manufacturing (AIM) Act in 2020, setting the stage for the phaseout of high-GWP refrigerants. Beginning in 2025, all new air conditioners must use refrigerants with a Global Warming Potential (GWP) of 750 or less.
For comparison, the commonly-used R-410A has a GWP of 2,088.
To meet these new standards, manufacturers will transition to A2L refrigerants, which are “mildly flammable” but significantly more eco-friendly.
A2L Refrigerants Explained
A2L refers to a class of refrigerants that, as mentioned, are “mildly flammable” but safe to use with the proper equipment and precautions. This category includes both single-component refrigerants and blends.
Two of the most common A2L refrigerants are R-32 and R-454B, both of which have lower GWP and have been used in HVAC systems for years.

Why Is the 2025 HVAC Refrigerant Change Beneficial?
The mild flammability of A2L might raise some concerns, especially compared to non-flammable A1 refrigerants. However, A2L refrigerants are difficult to ignite and are designed with safety in mind. Here’s why:
Higher Minimum Ignition Energy (MIE)
It takes a lot to ignite A2L refrigerants - standing next to your AC with a lighter wouldn’t cause a reaction.
Higher Lower Flammability Limit (LFL)
A2L refrigerants require a very high concentration in the air to even have a chance of igniting.
Lower Heat of Combustion (HOC)
If an A2L does ignite, it releases far less energy than other flammable gasses.
Lower Burning Velocity (VC)
In the rare event of ignition, the flames spread slowly, reducing the risk.
Additionally, A2L refrigerants are much less toxic than B-series like ammonia, making them one of the safest refrigerant classes available. And, of course, they’re much better for the environment, reducing your carbon footprint while keeping your home comfortable.
What Homeowners Should Know About the 2025 Refrigerant Change
As a homeowner, there’s no need to worry about major changes to your existing system. If you’re planning to upgrade, though, there are a few things to keep in mind. You won’t need special equipment to use an HVAC system with A2L refrigerant, but due to the redesign, the price of A2L units is expected to increase.
If your current HVAC system is older, it might be wise to consider upgrading to an A2L-based system before the regulations fully take effect.
Not sure if it’s time to replace your system? Here are a few signs to look for:
• Your system is out of warranty, and repair costs are rising.
• You’re experiencing frequent breakdowns and multiple repairs each year.
• Your energy bills are unusually high for the season.
• Your AC can’t keep up with your home’s cooling demands.
