If you use a central air conditioning system in Ohio, chances are your unit runs on R-410A refrigerant. This refrigerant has been widely used for years, but starting January 1, 2025, new laws will prohibit the manufacture, import, and sale of HVAC systems using R-410A. The reason? R-410A has a high Global Warming Potential (GWP), leading to stricter environmental regulations.
Is R-410A Refrigerant Being Phased Out?
The short answer, yes. The phaseout of R-410A refrigerant officially begins in 2025 as part of global efforts to reduce greenhouse gas emissions. The U.S. Environmental Protection Agency (EPA) has enacted policies to limit the production and use of hydrofluorocarbons (HFCs), including R-410A.
Why Is R-410A Being Phased Out?
- High Global Warming Potential (GWP) – R-410A has a GWP of 2,088, meaning it traps thousands of times more heat in the atmosphere than carbon dioxide.
- Environmental Regulations – The American Innovation and Manufacturing (AIM) Act supports the reduction of HFC refrigerants like R-410A.
- New Industry Standards – HVAC manufacturers are switching to lower-GWP alternatives like R-32 and R-454B.
How Long Will R-410A Be Available?
Although the R-410A phaseout officially begins in 2025, it will still be available for a limited time. The EPA’s phasedown schedule gradually reduces production, meaning supplies will decline and prices will increase. By 2030, most remaining R-410A will be from recycled or reclaimed sources, making repairs expensive.
If your system still uses R-410A refrigerant, now is the time to plan for an upgrade. Learn more about the EPA’s refrigerant phasedown timeline.
How Will the R-410A Phaseout Impact Homeowners?
The phaseout of R-410A refrigerant will affect homeowners in several ways:
- Higher Repair Costs – As production of R-410A decreases, its price will rise, making AC repairs more expensive.
- System Compatibility Issues – New AC models will not be compatible with R-410A, meaning existing systems may become outdated.
- Increased Efficiency – Newer systems using R-32 or R-454B will be more energy-efficient, lowering cooling costs in the long run.
- New Installation Requirements – HVAC professionals must be trained and certified to handle the next generation of refrigerants.
According to Carrier, R-410A systems cannot be retrofitted with new refrigerants, meaning homeowners will eventually need full system replacements (Carrier Refrigerant Guide).
Will R-410A refrigerant be illegal after 2025?
Nope! R-410A will not be illegal in 2025, but its production and sale in new HVAC systems will be banned. Homeowners with existing R-410A air conditioners can still use them, but repair costs will increase as refrigerant supplies decline.
What Should Homeowners Do if Their System Still Uses R-410A?
If your AC still runs on R-410A, here’s what you should do:
- Get an inspection – A professional can assess your system’s condition.
- Plan for an upgrade – If your unit is over 10 years old, upgrading to a system using R-32 or R-454B will save money long-term.
- Maintain your current system – Regular HVAC maintenance can extend its lifespan and delay replacement costs.
What Are the Best Alternatives to R-410A Refrigerant?
As R-410A refrigerant is phased out, two primary alternatives are emerging: R-32 and R-454B. These new refrigerants provide better energy efficiency, lower environmental impact, and meet updated regulations for HVAC systems.
1. R-32 Refrigerant
R-32 is a high-efficiency refrigerant with a Global Warming Potential (GWP) of 675, which is 68% lower than R-410A. It transfers heat more effectively, meaning air conditioners using R-32 consume less electricity while providing the same level of cooling.
Because of its lower environmental impact, R-32 is already used in many modern HVAC systems and is expected to become even more widespread in the coming years.
2. R-454B (Puron Advance) Refrigerant
R-454B, also known as Puron Advance, is another leading replacement. With a GWP of 466, it has 78% less environmental impact than R-410A refrigerant. It improves overall system efficiency, helping homeowners save on energy costs.
Unlike older refrigerants, R-454B does not contribute to ozone depletion, making it a more sustainable choice. It is expected to replace R-410A in most new residential HVAC systems as manufacturers shift toward greener technologies.
Can You Retrofit an R-410A System to Use R-32 or R-454B?
Unfortunately, no, R-410A systems cannot be retrofitted to use R-32 or R-454B. These refrigerants require different pressures, lubricants, and system components. Attempting a retrofit could damage your AC unit, void your warranty, and reduce efficiency.
If your air conditioner still uses R-410A, it’s best to plan for a replacement rather than attempting an incompatible retrofit. Find out what to look for in a new system in our AC buying guide.
Should You Replace Your R-410A System Now?
If your air conditioner is over 10 years old, now may be the best time to upgrade to a new system that supports R-32 or R-454B. Here’s why:
- Future-Proof Your Home – New refrigerants comply with upcoming laws, avoiding costly retrofits later.
- Lower Cooling Costs – Systems designed for R-32 or R-454B are more energy-efficient.
- Avoid Expensive Repairs – As R-410A becomes scarce, repair costs will rise.
To find out if your system uses R-410A refrigerant, check the manufacturer’s label on your outdoor AC unit or contact a professional.
