The New Refrigerants in Heat Pumps (2025 Update)
What R-32 and R-454B Mean for Your Home, the Environment, and Your Wallet
Why the Change in Refrigerants?
For years, heat pumps used R-410A—an efficient but high global warming potential (GWP) refrigerant. As global climate goals tighten and regulations evolve, R-410A is being phased out in favor of more eco-friendly options.
This shift is driven by updates to international treaties like the Montreal Protocol, and increasing pressure to reduce carbon footprints in residential and commercial buildings. Enter the new generation of refrigerants: R-32 and R-454B.
Meet the New Players: R-32 and R-454B
R-32
GWP: ~675 (vs. 2088 for R-410A)
Higher efficiency and lower charge volumes
Works well in extreme climates
Mildly flammable (A2L rating) but safe when handled properly
R-454B
GWP: ~466 (even lower than R-32)
Designed for next-gen systems with optimal performance
Safe for residential use under updated HVAC standards
Quickly becoming the new standard for eco-conscious HVAC solutions
Important: R-410A and New Refrigerants Are NOT Compatible
If you’re currently using an R-410A system, you cannot switch refrigerants without replacing the entire unit.
Why?
Different pressure and chemical properties
Incompatible compressors, coils, and internal components
New refrigerants are mildly flammable and need specialized parts & tools
Attempting to retrofit could void warranties, reduce efficiency, or even damage the system.
How This Impacts You Financially
Installation Costs
New systems may carry a slightly higher upfront cost. In general, equipment is expected to increase by 10%-15%.
However, prices are expected to drop as technology becomes mainstream
Energy Efficiency
Systems using R-32 or R-454B are up to 10% more efficient
Lower energy consumption = smaller utility bills
Incentives & Rebates
Many programs offer rebates for low-GWP equipment
Upgrading now may qualify you for 2025 tax credits or utility incentives
Long-Term Value
Fewer repairs, better warranties, longer lifespan
Improved resale value as buyers look for sustainable upgrades
Future-proof compliance with environmental regulations
Should You Upgrade?
If your current system is aging, inefficient, or due for replacement, this is a great time to explore new heat pump options using R-32 or R-454B. These systems offer high performance and peace of mind knowing you're making a lower-impact choice.
