2025 HVAC Refrigerant Changes: What Boston Homeowners Need to Know

As our nation moves toward a future of greater environmental responsibility, the HVAC industry is doing its part by establishing new mandates that protect against global warming. These mandates include changes to requirements around refrigerants used in air conditioning systems. 

Below, the HVAC experts at Suburban HVAC discuss the 2025 changes to refrigerant mandates and the eco-friendly options currently available. 

What Is the 2025 HVAC Refrigerant Change?

Mandates regarding refrigerants have changed over the years as the HVAC industry has evolved. It began with the phasing out of freon in favor of R-410A. However, starting in 2025, the Environmental Protection Agency (EPA) will require that all new HVAC systems switch to refrigerants with lower Global Warming Potential (GWP). Using more eco-friendly HVAC refrigerant options like R-32 or R-454B, which have a much smaller environmental impact, is a key step in combating climate change.

How The 2025 Refrigerant Changes Will Impact You

The mandates from the EPA are only applicable to HVAC manufacturers– homeowners in Boston who have current systems that use older refrigerants will not be required to replace their systems. However, these changes will still impact you:

• R-410A costs will rise: As R-410A is phased out, the price of refrigerant will rise, making it more expensive to repair or recharge your current system.
• AC units will be more expensive: Homeowners should expect to see 20-30% price increases as new manufacturers adopt the technology and materials that comply with new mandates. 
• New systems will be more efficient: New systems that use eco-friendly refrigerants are also more energy-efficient. If you’re considering upgrading soon, these energy savings could help offset the initial cost of a new system.
• HVAC technicians will need more training: Because newer refrigerant options are mildly flammable, the HVAC industry is working hard to ensure that technicians have the proper training. For this reason, it’s critical to ensure you only work with a licensed and insured professional for any HVAC services.

Eco-Friendly Alternatives to R-410A

The greatest concern with R-410A is its high GWP of 2,088 when released into the atmosphere. That’s why the industry is moving toward eco-friendly alternatives, including R-454B and R-32. Both of these refrigerants have much lower GWP and are highly energy-efficiency:

• R-454B: This blended refrigerant has a GWP of 466 and does not harm the ozone layer. 
• R-32: This single-component refrigerant has a GWP of 675 and also does not harm the ozone layer.

How to Prepare for the Refrigerant Changes

There are a few ways that Boston homeowners can prepare for these refrigerant changes:

• Schedule maintenance: Regular maintenance can help keep your system operating efficiently, delaying the need for a complete replacement.
• Consider replacement: If your current AC is old, inefficient, or unreliable, it may be worth upgrading to a new system. These units are highly energy-efficient and eliminate the concern for rising R-410A costs.
• Consult a professional: Schedule service with the team at Suburban HVAC for a full assessment of your AC system and guidance on whether it’s time to upgrade to a new system.
