HVAC systems are undergoing a change in 2025, and it’s one that homeowners should be aware of. Older types of refrigerants are being phased out in favor of more eco-friendly options due to new regulations from the Environmental Protection Agency (EPA). Updates to minimize negative environmental impact while maximizing more efficient technology are usually a good thing, but you may be wondering how these changes could directly impact your South Carolina home’s HVAC system. Keep reading this blog from the HVAC experts at Carolina Custom Air to learn more about the latest guidelines and what they mean for you.
Why Did HVAC Refrigerants Change in 2025?
The refrigerant changes that recently went into effect on January 1 of this year are part of the EPA’s efforts to fight global warming, climate change, and ozone depletion. Previously common refrigerants like R-410A will no longer be used because of their high Global Warming Potential (GWP). Going forward, HVAC systems will be manufactured with alternative refrigerants that have a lower GWP, are far more environmentally friendly, and help the entirety of the HVAC industry reduce its carbon footprint.
New Refrigerants: R-454B & R-32
The more sustainable refrigerant replacements you should know about are called R-454B and R-32. These next-gen refrigerants have a significantly lower GWP than R-410A and were designed with excellent heat transfer properties that greatly increase HVAC efficiency. This not only extends your system’s life, but also lowers your utility bills! These improved replacement refrigerants also have lower toxicity and flammability than previous versions, which makes them a safer choice for use in Charleston homes and businesses.
How Will the Change Impact You?
So, what does this change mean for you, the Charleston-area homeowner? The good news is there’s absolutely no need to do anything right away. Any existing systems that use R-410A can, and should, still be serviced as usual. However, over time it will become harder to find replacement parts for systems that use the older refrigerant as R-454B and R-32 become the industry standard. Some HVAC systems may be compatible with the new refrigerants without major upgrades, but if yours is not, you may want to begin planning for an AC replacement in the coming years. Failure to do so could leave you with an outdated unit that isn’t compliant with regulations, is increasingly more expensive to operate, and harms the environment due to its inferior refrigerants.
