What Homeowners Should Know About R-454B: The Next-Generation Refrigerant

The HVAC industry is moving toward more sustainable solutions, and one of the biggest changes impacting homeowners is the introduction of R-454B refrigerant. At DuctlessWayne, we’re helping local homeowners navigate these updates, especially when it comes to ductless air conditioning systems.

Why R-454B Is Replacing R-22 and R-410A

Traditional refrigerants like R-22 and R-410A are being phased out due to their high global warming potential (GWP) and environmental risks. In contrast, R-454B offers a significantly lower GWP—about 78% less than R-410A—making it a more eco-friendly option. This shift is part of a larger industry move away from hydrofluorocarbons (HFCs) toward newer hydrofluoroolefins (HFOs) that deliver high performance with a reduced environmental impact.

The U.S. Department of Energy is supporting this effort through initiatives like the Cold Climate Heat Pump Challenge, which encourages the development of efficient systems that can perform well even in freezing temperatures. These advances are making heat pumps more versatile and attractive to homeowners across the country.

What to Expect When Upgrading Your System

If you're planning to replace your HVAC system, it’s important to know that systems using R-454B often require new refrigerant lines and equipment that’s specifically compatible with the refrigerant. Working with professionals ensures you get the right setup the first time.
