Why Did HVAC Refrigerants Change in 2025?

The 2025 refrigerant updates are part of the EPA’s ongoing mission to reduce the environmental impact of air conditioning and refrigeration systems. Traditional refrigerants like R-410A have been identified as significant contributors to global warming due to their high Global Warming Potential (GWP).

In response, the EPA has enforced a transition to low-GWP refrigerants under the American Innovation and Manufacturing (AIM) Act. This change is designed to align with national climate goals while enhancing energy efficiency in both residential and commercial cooling systems.

New Refrigerants: R-454B & R-32

With the phase-out of R-410A, two environmentally friendly alternatives have taken its place: R-454B and R-32. These new refrigerants offer several benefits over their predecessors, including:

  • Lower environmental impact: R-454B and R-32 both have a Global Warming Potential (GWP) that is significantly lower than R-410A’s GWP of 2,088.
  • Enhanced energy efficiency: HVAC systems using R-454B and R-32 operate more efficiently, which can lead to lower energy costs for homeowners.
  • Regulatory compliance: With R-410A being phased out, HVAC manufacturers are transitioning to systems designed for R-454B and R-32 to meet EPA requirements and industry standards.

How Will the Change Impact You?

Homeowners may be wondering how the transition to new refrigerants will affect their current air conditioning systems and future HVAC needs. Here’s what to keep in mind:

  • You can still use your current system: If your AC runs on R-410A, you don’t need to replace it right away. However, as R-410A is phased out, it may become more expensive and harder to source for repairs.
  • New systems will use R-454B or R-32: If you’re installing a new air conditioner in 2025 or later, it will likely be designed for these more energy-efficient and environmentally friendly refrigerants.
  • Know your refrigerant type: Not sure what refrigerant your system uses? Check your unit’s label or ask an HVAC professional to confirm.
  • Upgrading could save you money: If your current AC is aging or requires frequent repairs, investing in a new system with R-454B or R-32 could lower your energy costs and reduce maintenance expenses over time.
