Major changes are on the way for the heating and cooling business! Cooling systems moving 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 satisfy updated regulations about global warming. But what does that mean for your present HVAC system and any new services?
This transition will minimize the environmental effect of our air conditioning systems. In 2025, new AC systems will use new class of refrigerants that better align with climate goals. If you're thinking about getting an AC replacement soon, this is the perfect time to explore how these changes can influence your home's comfort.
Why Is R-410a Refrigerant Being Phased Out by New Regulations?
For years, R-410a was the go-to refrigerant for residential air conditioners because it worked so well. But studies showed that R-410a still contributes to global warming. As a result, the Environmental Protection Agency (EPA) established an initiative back in 2021. The industry will gradually discontinue R-410a to replace it with refrigerants that are more eco-friendly.
The HVAC industry has undergone shifts like this before. When the industry phased out R-22 (commonly called Freon) to R-410a, residents like you had to adapt. And similarly, this shift will affect how systems are engineered as well as the optimal methods for HVAC maintenance. Both property owners and HVAC technicians should prepare for these new refrigerants if they wish to continue enjoying the most secure, most cost-effective cooling possible.
Which New Refrigerant Is Replacing R-410a?
The upcoming 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 greatly lowering their global warming potential (GWP) compared to R-410a.
R-454B refrigerant is believed to be particularly efficient due to its GWP being around 78% lower than R-410a. Although R-454B refrigerant is believed to be more flammable than R-410a, enhancements to system configurations and maintenance practices will ensure servicing is just as safe to perform. Additionally, modern cooling systems using R-454B refrigerant are much more energy efficient, contributing to big savings on energy bills over time, especially if you keep up with routine HVAC maintenance.
This change isn't simply about changing the refrigerant—it impacts the whole HVAC system because the characteristics of R-454B refrigerant make it incompatible with older systems. Ultimately, every household and business using R-410a will need to switch to one of the new systems.
R-410a Replacement: What Do I Need to Do to Make the Shift to New HVAC Refrigerants?
Changing to the new refrigerants will not be as straightforward as swapping out the new coolants with what's used in your current HVAC system. That's because the distinct properties of R-454B refrigerant and R-32 refrigerant mean you can't use the new refrigerants in a system designed to use R-410a. But don't be concerned—you can still use your current R-410a system for now. Just keep in mind that as time passes, the expense of repairs and tune-ups will rise as R-410a becomes scarcer.
Anticipating the changes is the most effective way to stay on top of things. If your AC system is already getting old, this is the best time to think about upgrading to a newer model that uses the new R-454B refrigerant. Plus, the staff here at House of Heating Incorporated can help you in switching with flexible options for HVAC replacement financing.
What HVAC Refrigerant Does My Air Conditioner Use?
Unsure which refrigerant your AC system utilizes? In general, you can easily learn this information by inspecting the label on your outdoor unit. This label indicates the type of refrigerant, the model number and numerous other details about your cooling system.
But if you are unable to decipher the label or are missing your user manual, remain calm! You can always connect with one of the skilled technicians at House of Heating Incorporated to assist you in identifying the refrigerant. Get all the info you need by reaching out at 715-384-3163.
