R-410A is a reliable refrigerant, but it has a high global warming potential. This means it’s been contributing to climate change and increased greenhouse gas emissions. The good news is that R-410A does not harm the ozone layer. However, there are now better options. The R-410A GWP is significantly higher than the newer environmentally friendly refrigerants that are now on the market. That’s why regulators and manufacturers are moving toward R-454B and R-32—they’re considered low GWP refrigerants.

Beginning in January 2025, manufacturers were no longer allowed to produce new systems using R-410A. That being said, R-410A will remain available for repairs, maintenance, and servicing for years to come. This is good news for homeowners who recently purchased their system. Most people won’t notice changes unless they purchase a new HVAC system after 2025.

R-454B offers dramatically lower global warming potential and is a primary choice for major HVAC brands. There’s also the option for R-32. Both offer solid energy efficiency and deliver a reduced environmental impact compared to R-410A.

Absolutely. Homeowners can continue operating their R-410A air conditioning system as normal for its full lifespan. The mandate only affects production of new HVAC systems. Homeowners don’t need to worry about removing or replacing existing equipment until it’s necessary.

Yes. R-410A will still be stocked for years, though repair costs may gradually rise as supply decreases. Homeowners with newer R-410A units shouldn’t have to deal with any immediate
