Major changes are on the way for the heating and cooling industry! Cooling systems shifting from R-410a to newer refrigerants like R-454B refrigerant and R-32 refrigerant will be implemented in 2025. These new coolants are developed to be more beneficial to the environment and comply with updated regulations about global warming. But what does that mean for your present HVAC system and future services?

This transition will minimize the environmental impact of our air conditioning systems. In 2025, new AC systems will utilize a a different class of refrigerants that better align with climate goals. If you're contemplating getting an AC replacement soon, this is the perfect time to learn more about how these new refrigerants can influence your home's comfort.

Why Are They Phasing Out R-410a for New HVAC Refrigerant?

For a long time, R-410a was the preferred refrigerant for residential air conditioners because of its effectiveness. But studies showed that R-410a still negatively impacts global warming. In response, the Environmental Protection Agency (EPA) enacted a plan back in 2021. The industry will gradually discontinue R-410a to make room for refrigerants that are more environmentally friendly.

The HVAC industry has undergone shifts like this before. When the industry moved away from using R-22 (commonly called Freon) to R-410a, residents like you had to follow suit. And similarly, this shift will affect how systems are constructed as well as the best practices for HVAC maintenance. Both residents and HVAC technicians need to prepare for these new refrigerants if they wish to continue enjoying the most reliable, most energy-efficient cooling possible.

New HVAC Refrigerants Replacing R-410a?

The coming refrigerants are categorized under the new "A2L" classification and include the newest R-454B refrigerant and R-32 refrigerant coolants. They're developed to provide the same effective cooling while substantially decreasing their global warming potential (GWP) compared to R-410a.

R-454B refrigerant is believed to be especially efficient due to its GWP being approximately 78% lower than R-410a. While R-454B refrigerant is technically more flammable than R-410a, improvements to system configurations and maintenance practices will ensure servicing is just as safe to perform. Additionally, modern cooling systems using R-454B refrigerant are considerably more energy efficient, leading to substantial savings on energy bills over time, especially if you keep up with routine HVAC maintenance.

This switch isn't just about changing the refrigerant—it impacts the whole HVAC system because the properties of R-454B refrigerant make it incompatible with older systems. In time, every residence and business using R-410a will be required to transition to one of the new systems.

R-410a Replacement: What Do I Need to Do to Switch to New HVAC Refrigerants?

Switching to the new refrigerants will not be as simple as substituting what's used in your home's HVAC system. That's because the distinct properties of R-454B refrigerant and R-32 refrigerant make existing R-410a systems incompatible.  But don't be concerned—you can continue to use your current R-410a system for now. Just remember that as time passes, the price of repairs and tune-ups will increase as R-410a becomes harder to find.

Planning ahead is the best way to manage things. If your AC system is already getting old, this is the ideal time to think about upgrading to a newer model that uses the new R-454B refrigerant. Plus, the team here at Fire & Ice HVAC can support you with making the transition with flexible options for HVAC replacement financing.

What HVAC Refrigerant Does My Air Conditioner Use?

Unsure which refrigerant your AC system uses? In general, you can easily find this information by inspecting the label on your outdoor unit. This label indicates the type of refrigerant, the model number and various other particulars about your cooling system.

But if you can't read the label or can't find your user manual, don't stress! You can always connect with one of the expert technicians at Fire & Ice HVAC to assist you in determining this information. Get all the details you need by reaching out at 703-595-4157.
