Due to the American Innovation and Manufacturing (AIM) Act of 2020, the HVAC industry continues transitioning away from harmful chemicals that contribute to pollution and may cause health problems. A new refrigerant change for air conditioning units and heat pumps in 2025 will make many older systems incompatible with Environmental Protection Agency (EPA) regulations.
If you worry about what these changes mean for your HVAC system, you’re not alone. This is the perfect opportunity to upgrade your cooling system to an energy-efficient model using the appropriate refrigerant. Here, our Climate Experts Air, Plumbing & Electric team explains what you need to know about this essential transition.
A Comprehensive Overview of the 2025 Refrigerant Change
Starting on January 1, 2025, all residential and light commercial air conditioning in the country must use A2L refrigerants and phase out R-22. A2L refrigerants are less flammable and less toxic than the A3 variety and B series, making them the safest class to use in HVAC.
As of the new year, the main refrigerants for air conditioners and heat pumps are R-454B, R-410A, and R-32. Equipment made before the refrigerant change deadline has a one-year grace period for installation.
The Impact of Change on Older HVAC Systems
If your older HVAC system relies on the now-outdated R-22 refrigerant and develops a leak, refilling it with the same chemical will be challenging. R-22 is difficult to find and expensive to purchase—if you can locate it at all.
Unfortunately, you can’t use A2L refrigerant in older A1 units since they’re not compatible. Instead of dealing with this hassle, now is the time to consider upgrading your HVAC to an energy-efficient model that uses an approved refrigerant.
Energy Efficiency and Environmental Benefits To Consider
Approved refrigerants like R-32 have a lower Global Warming Potential (GWP) and are designed with safety in mind. Their low flammability and toxicity make them safer for both people and the environment. In the event of a leak, they are unlikely to ignite or pose health risks.
Because the refrigerant update requires upgrades to existing HVAC and compatibility with newer equipment, it promotes energy efficiency. You can enjoy a fully functional cooling system with optimized performance without worrying about paying for wasted energy.
What You Can Do Now To Prepare
What can you do to prepare for the new changes? Consider these tips:
- Schedule an HVAC inspection to learn about your equipment
- Consider upgrading to a new model
- Pay attention to timeframes to comply with the EPA
