Big changes are on the way for the heating and cooling industry! Cooling systems transitioning 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 friendlier to the environment and satisfy updated regulations about global warming. But what does that mean for your current HVAC system and any new services?
This transition will minimize the environmental effect of our air conditioning systems. Beginning in 2025, new AC systems will employ 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 investigate how these new refrigerants can influence your home's comfort.
Why Are They Phasing Out R-410a for New HVAC Refrigerant?
For years, R-410a was the preferred refrigerant for residential air conditioners because of its efficiency. But studies showed that R-410a still negatively impacts global warming. As a result, the Environmental Protection Agency (EPA) enacted an initiative back in 2021. The industry will gradually eliminate R-410a to replace it with refrigerants that are more eco-friendly.
The HVAC industry has undergone changes like this before. When the industry switched from using R-22 (commonly called Freon) to R-410a, property owners like you had to follow suit. And just like then, this change will impact how systems are engineered as well as the recommended procedures for HVAC maintenance. Both residents and HVAC technicians must prepare for these new refrigerants if they wish to continue enjoying the most reliable, most economical cooling possible.
What 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 designed to provide the same powerful cooling while greatly lowering their global warming potential (GWP) compared to R-410a.
