New HVAC Refrigerant Changes in 2025: What You Need to Know
New HVAC Refrigerants in 2025: What Homeowners in West Allis & Milwaukee Need to Know
Major changes are coming to the HVAC industry starting in 2025! The current R-410a refrigerant will be phased out in favor of new, eco-friendly refrigerants like R-454B and R-32. These changes are designed to reduce environmental impact while aligning with updated global warming regulations.
If you’re considering an AC replacement or upgrade, now is the perfect time to understand how these changes will affect your HVAC system and comfort in your West Allis or Milwaukee home.
Why Is R-410a Refrigerant Being Phased Out?
For years, R-410a has been the standard refrigerant for residential air conditioners because of its efficiency. However, it still contributes to global warming, prompting the Environmental Protection Agency (EPA) to implement a phase-out plan as part of the American Innovation and Manufacturing (AIM) Act.
This isn’t the first time the HVAC industry has seen a refrigerant change. Homeowners previously transitioned from R-22 (Freon) to R-410a—a process that impacted HVAC system design, maintenance, and upgrades.
The new refrigerants, R-454B and R-32, will deliver improved efficiency while significantly lowering global warming potential (GWP).
What Are the New Refrigerants Replacing R-410a?
The next generation of refrigerants falls under the A2L classification. These include:
R-454B Refrigerant:
78% lower GWP than R-410a.
Improved energy efficiency for lower utility costs.
Safe servicing with updated manufacturing practices.
R-32 Refrigerant:
A single-component refrigerant with efficient cooling capabilities.
Lower GWP compared to older refrigerants.
While R-454B and R-32 are slightly more flammable, enhanced system designs and safety regulations will ensure these refrigerants can be used and maintained safely by trained HVAC professionals.
Will My Current HVAC System Work with the New Refrigerants?
Unfortunately, no. Systems designed for R-410a cannot operate with R-454B or R-32 due to their chemical differences.
However, you don’t need to replace your system immediately. Your current R-410a system will still operate efficiently for now, but repairs and maintenance will become more expensive as R-410a becomes harder to source.
What Should Homeowners Do to Prepare?
Plan Ahead for System Upgrades:
If your AC system is 10+ years old or requires frequent repairs, upgrading to a newer, energy-efficient model that uses R-454B or R-32 is a smart choice.Budget for the Transition:
