Big 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 implemented in 2025. These new coolants are engineered to be more beneficial to the environment and satisfy new regulations about global warming. But what does that mean for your present HVAC system and future services?
This shift will reduce the environmental impact of our air conditioning systems. Beginning in 2025, new AC systems will utilize an alternative class of refrigerants that more closely match with climate goals. If you're thinking about getting an AC replacement soon, this is the perfect time to explore 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 it worked so well. But research revealed that R-410a still contributes to global warming. Because of this, the Environmental Protection Agency (EPA) enacted a plan back in 2021. The industry will progressively eliminate 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, property owners like you had to adapt. And similarly, this change will impact how systems are engineered as well as the recommended procedures for HVAC maintenance. Both property owners and HVAC technicians should plan for these new refrigerants if they want to continue enjoying the safest, most economical cooling possible.
New HVAC Refrigerants Replacing R-410a?
The new batch of refrigerants belong to the new "A2L" classification and encompass the newest R-454B refrigerant and R-32 refrigerant coolants. They're designed to offer the same effective cooling while greatly lowering their global warming potential (GWP) compared to R-410a.
R-454B refrigerant is believed to be especially effective due to its GWP being approximately 78% less than R-410a. Although R-454B refrigerant is believed to be more flammable than R-410a, enhancements to system designs and maintenance practices will ensure servicing is just as safe to perform. In addition, modern cooling systems using R-454B refrigerant are much more energy efficient, leading to considerable savings on energy bills over time, especially if you keep up with routine HVAC maintenance.
This transition isn't only about substituting the refrigerant—it affects the whole HVAC system because the components of R-454B refrigerant make it incompatible with older systems. In time, every residence and business using R-410a will need to transition to one of the new systems.
R-410a Replacement: How Can I Prepare to Switch to New HVAC Refrigerants?
Transitioning to the new refrigerants isn't 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 keep using your current R-410a system for now. Just know that as time progresses, the cost of repairs and tune-ups will increase as R-410a becomes scarcer.
Preparing in advance is the most effective way to stay on top of things. If your AC system is currently aging, this is the ideal time to think about upgrading to a newer model that uses the new R-454B refrigerant. Plus, the staff here at Halverson Brothers Inc can assist you in switching with flexible options for HVAC replacement financing.
Which HVAC Refrigerant Is in My Air Conditioner?
Uncertain which refrigerant your AC system employs? In general, you can easily find this information by examining the label on your outdoor unit. This label shows the type of refrigerant, the model number and various other details 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 call one of the professional technicians at Halverson Brothers Inc to assist you in identifying the refrigerant. Get all the details you need by contacting us at 715-352-4052.
