Key Takeaways
- The Environmental Protection Agency (EPA) is phasing out high-Global Warming Potential (GWP) refrigerants like R-410A under the AIM Act
- As of 2025, systems with GWP above 700 can no longer be manufactured or imported
- As of 2026, these systems can no longer be installed
- New HVAC systems must meet low-GWP requirements
- Delaying upgrades may lead to higher costs and compliance risks
What Are EPA Refrigerant Regulations Under the AIM Act?
In January 2020, the EPA introduced the American Innovation and Manufacturing (AIM) Act. This law aims to phase down hydrofluorocarbon (HFC) refrigerants and reduce environmental harm.
HFCs are greenhouse gases used in residential and commercial HVAC systems. They also appear in refrigeration units and industrial cooling equipment. The EPA targets these refrigerants because of their high Global Warming Potential (GWP). GWP measures how much heat a gas traps compared to carbon dioxide (CO2).
CO2 serves as the baseline with a GWP of 1. This indicates a relatively low environmental impact. In comparison, propane has a GWP of just 3. However, many common refrigerants have much higher values.
Through the AIM Act, the EPA plans to reduce high-GWP HFC consumption by 85% over 15 years.
R-410A Phase Out: Why It Matters
One of the main targets of EPA refrigerant regulations is R-410A. This refrigerant is widely used in air conditioners, heat pumps, and commercial refrigeration systems.
However, R-410A has a GWP of 2,088. As a result, it traps up to 2,000 times more heat than CO2. Because of this, the EPA has prioritized its phase down.
The R-410A phase-out represents one of the biggest changes in the HVAC industry in decades. Businesses and homeowners must now prepare for new refrigerant standards.
The phase-out of R-410A represents one of the most significant shifts in the HVAC industry in decades, driven by evolving environmental regulations aimed at reducing greenhouse gas emissions.
This transition follows the earlier phase-out of R-22, which was fully implemented in 2020 due to its ozone-depleting properties. As a result, businesses and property owners must now prepare for the next generation of refrigerants, which have lower global warming potential (GWP).
EPA Refrigerant Timeline: 2025-2026 Changes
The AIM Act has already introduced major changes to HVAC systems:
- January 1, 2025: The EPA restricted the manufacture and import of systems using refrigerants with GWP above 700.
- January 1, 2026: Facilities can no longer install systems that exceed this GWP limit.
- By mid-2026: The EPA aims for widespread adoption of low-GWP refrigerants.
As a result, AIM compliant systems are now the industry standard.
How Changes to Refrigerants Impact Business
EPA refrigerant regulations are already affecting system availability, pricing, and installation timelines.
- Supply of older refrigerants is shrinking.
- Equipment costs are rising due to demand shifts.
- Lead times for compliant systems are increasing.
At the same time, all new systems in retail, cold storage, and industrial facilities must meet GWP requirements. Exisiting systems may continue operating, but only until replacement becomes necessary.
Because of these changes, what used to be a routine refrigerant recharge can now result in delays or full system upgrades.
What Businesses Need to Know
For businesses, these HVAC and refrigeration regulations carry added urgency.
Older systems that rely on R-410A may become more expensive to maintain. In addition, sourcing refrigerants may becomemore difficult as supply continues to tighten.
Businesses involved in:
- Retail
- Restaurants
- Warehousing and cold storage
should begin planning upgrades now to avoid future disruptions.
Should You Upgrade Your HVAC/Refrigeration Systems Now?
If your system uses R-410A or another high-GWP refrigerant, early action is critical.
Upgrading now can help you:
- Avoid rising equipment and refrigerant costs
- Reduce downtime and supply delays
- Stay compliant with EPA regulations
- Improve energy efficiency and long-term savings
By contrast, waiting too long may limit your options for change and increase costs.

FAQ: EPA Refrigerant Regulations & R-410A Phase-Out
When will R-410A be banned?
R-410A is not fully banned yet, but the EPA has restricted new systems from using it. As of 2025, manufactuers can no longer produce systems with high-GWP refrigerants. As of 2026, installation of these systems is no longer allowed.
What refrigerant replaces R-410A?
New systems use lower-GWP alternatives such as R-454B and R-32. These refrigerants meet EPA requirements and reduce environmental harm.
Are the new refrigerants like R-454B and R-32 safe to use?
Yes, but they come with additional considerations. New refrigerants like R-454B and R-32 are classified as A2L (mildly flammable), which means updated safety standards, installation practices, and system design requirements apply. Most of these complexities are handled by manufacturers and trained professionals. Working with an experienced partner ensures your system is installed safely and meets all current codes and regulations.
Can I still use my existing HVAC and refirgeration system?
Yes. Existing systems can continue operating. However, repairs and refrigerant availability may become more expensive over time.
What is the AIM Act?
The AIM Act is a U.S. law that reuces the use of high-GWP refrigerants by 85% over 15 years. It drives the transitions to more environmentally friendly HVAC and refrigerations systems.
