Refrigerant is the substance that HVAC systems such as air conditioners, heat pumps, and ductless mini-splits use to do their job. Basically, if your HVAC system is keeping your home cool and comfortable, refrigerant is doing the heavy lifting behind the scenes.
In 2025, new federal regulations have changed the type of refrigerant used in air conditioning systems, leaving many South Jersey homeowners wondering: What does this mean for me? Whether you’re due for an AC upgrade or just want to be prepared, our team at Clay’s Climate Control has put together this blog to help you better understand these changes.
Why Did HVAC Refrigerants Change in 2025?
The shift in refrigerants comes from updated Environmental Protection Agency regulations aimed at reducing environmental impact. Older refrigerants, like R-410A, create greenhouse gas emissions, which can harm the environment and contribute to climate change. To address this, the EPA has mandated a change to more eco-friendly refrigerants with lower global warming potential (GWP).
These changes aren’t new; refrigerants have been evolving for decades. You may remember when R-22 (Freon) was phased out in favor of R-410A. Now, as part of ongoing efforts to create more sustainable cooling solutions, R-454B and R-32 have become the new standard for residential air conditioning systems.
New Refrigerants: R-454B & R-32
The two new refrigerants, R-454B and R-32, are designed to be more efficient and environmentally friendly:
- R-454B: This refrigerant has a lower GWP than R-410A and is already being adopted by major HVAC manufacturers. It improves system efficiency while reducing emissions.
- R-32: Another alternative with even lower GWP, R-32 requires less refrigerant per system and operates at a similar efficiency level.
Both options offer better energy performance, which is a benefit for homeowners upgrading to a new system as it will keep utility costs down.
How Will the Change Impact Me?
If you already have a working AC system that uses R-410A, you don’t have to rush to replace it — at least not right away. Here’s what South Jersey homeowners should know about how this change can impact their HVAC system:
- AC repairs and maintenance: If your system needs a refrigerant recharge, R-410A will still be available, but costs may rise as supply decreases.
- Replacing your AC: If your system is nearing the end of its lifespan, upgrading to a new unit with R-454B or R-32 is a smart move to stay ahead of the changes and improve efficiency.
- How to check your refrigerant: If you’re unsure what type of refrigerant your system uses, check the manufacturer’s label on your outdoor unit or call a professional HVAC technician for guidance.
