Major changes are on the horizon for the heating and cooling business! Cooling systems shifting from R-410a to newer refrigerants like R-454B refrigerant and R-32 refrigerant will be coming in 2025. These new coolants are developed to be friendlier to the environment and satisfy updated regulations about global warming. But what does that mean for your present HVAC system and future services?
This change will decrease the environmental impact of our air conditioning systems. Starting with 2025, new AC systems will use new class of refrigerants that are more compatible with climate goals. If you're considering getting an AC replacement soon, this is the ideal time to investigate how these changes can affect your home's comfort.
Why Are They Phasing Out R-410a for New HVAC Refrigerant?
For a long time, R-410a was the go-to refrigerant for residential air conditioners because of its efficiency. But analysis revealed that R-410a still contributes to global warming. In response, the Environmental Protection Agency (EPA) established an initiative back in 2021. The industry will progressively phase out R-410a to replace it with refrigerants that are more environmentally friendly.
The HVAC industry has undergone shifts like this before. When the industry switched from using R-22 (commonly called Freon) to R-410a, residents like you had to follow suit. And similarly, this transition will impact how systems are designed as well as the optimal methods for HVAC maintenance. Both property owners and HVAC technicians should prepare for these new refrigerants if they want to continue enjoying the most reliable, most economical cooling possible.
What Refrigerant Is Replacing R-410a?
The new batch of refrigerants are categorized under the new "A2L" classification and encompass the newest R-454B refrigerant and R-32 refrigerant coolants. They're designed to offer the same powerful cooling while significantly reducing their global warming potential (GWP) compared to R-410a.
R-454B refrigerant is believed to be particularly useful due to its GWP being approximately 78% less than R-410a. Although R-454B refrigerant is actually more flammable than R-410a, improvements to system designs and maintenance practices will ensure servicing is just as safe to perform. Additionally, contemporary cooling systems using R-454B refrigerant are significantly more energy efficient, contributing to considerable savings on energy bills over time, especially if you keep up with routine HVAC maintenance.
This change isn't simply about replacing the refrigerant—it impacts the whole HVAC system because the characteristics of R-454B refrigerant make it not suitable for use in older systems. In time, every residence and business using R-410a will be required to switch to one of the new systems.
R-410a Replacement: How Can I Prepare to Transition to New HVAC Refrigerants?
Transitioning to the new refrigerants won't be as easy as swapping out the new coolants with what's used in your home's 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 worry—you can keep using your current R-410a system for now. Just be aware that as time passes, the cost of repairs and tune-ups will go up as R-410a becomes harder to find.
Preparing in advance is the best way to stay on top of things. If your AC system is already getting old, this is the best time to consider upgrading to a newer model that uses the new R-454B refrigerant. Plus, the HVAC specialists here at Ilten's can support you with making the transition with flexible options for HVAC replacement financing.
What Type of Cooling Refrigerant Is in My HVAC System?
Not sure which refrigerant your AC system employs? In general, you can easily learn this information by examining the label on your outdoor unit. This label displays the type of refrigerant, the model number and various other specifications about your cooling system.
But if you have difficulty reading the label or don't have your user manual, remain calm! You can always call one of the skilled technicians at Ilten's to assist you in identifying the refrigerant. Get all the info you need by reaching out at 319-208-2351.
