Major changes are coming 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 arriving in 2025. These new coolants are designed to be friendlier to the environment and comply with updated regulations about global warming. But what does that mean for your existing HVAC system and upcoming services?
This shift will minimize the environmental effect of our air conditioning systems. Starting with 2025, new AC systems will use a a different class of refrigerants that better align with climate goals. If you're thinking about getting an AC replacement soon, this is the opportune time to learn more about how these updates can affect your home's comfort.
Why Are They Phasing Out R-410a for New HVAC Refrigerant?
For years, R-410a was the standard refrigerant for residential air conditioners because of its effectiveness. But studies showed that R-410a still contributes to global warming. Because of this, the Environmental Protection Agency (EPA) implemented a strategy back in 2021. The industry will steadily eliminate R-410a to make room for refrigerants that are more eco-friendly.
The HVAC industry has undergone transitions like this before. When the industry switched from using R-22 (commonly called Freon) to R-410a, property owners like you had to adapt. And in the same way, this shift will impact how systems are designed as well as the optimal methods for HVAC maintenance. Both property owners and HVAC technicians must prepare for these new refrigerants if they want to keep experiencing the most reliable, most cost-effective cooling possible.
What Refrigerant Is 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 deliver the same efficient cooling while significantly reducing their global warming potential (GWP) compared to R-410a.
R-454B refrigerant is anticipated to be particularly effective due to its GWP being around 78% lower than R-410a. Although R-454B refrigerant is technically more flammable than R-410a, updates to system designs and maintenance practices will ensure servicing is just as safe to perform. Additionally, contemporary cooling systems using R-454B refrigerant are much more energy efficient, leading to considerable savings on energy bills over time, especially if you stay on top of routine HVAC maintenance.
This change isn't simply about swapping out the refrigerant—it impacts the whole HVAC system because the components of R-454B refrigerant make it not suitable for use in older systems. Ultimately, every home and business using R-410a will need to transition to one of the new systems.
R-410a Replacement: What Do I Need to Do to Change to New HVAC Refrigerants?
Changing to the new refrigerants isn't as easy 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 worry—you can keep using your current R-410a system for now. Just remember that as time goes on, the cost of repairs and tune-ups will rise as R-410a becomes scarcer.
Preparing in advance is the most effective way to manage things. If your AC system is already aging, this is the perfect time to contemplate investing in a newer model that uses the new R-454B refrigerant. Plus, the team here at Hix Air Conditioning Service, Inc. can support you with upgrading with flexible options for HVAC replacement financing.
What Type of Cooling Refrigerant Is in My HVAC System?
Uncertain which refrigerant your AC system employs? In general, you can easily find this information by checking the label on your outdoor unit. This label indicates the type of refrigerant, the model number and various other specifications about your cooling system.
But if you are unable to decipher the label or don't have your user manual, remain calm! You can always call one of the expert technicians at Hix Air Conditioning Service, Inc. to assist you in determining this information. Get all the details you need by giving us a call at 918-682-8238.
