R-410A Refrigerant — What Homeowners Need to Know

Professional R-410A Refrigerant — What Homeowners Need to Know in Asheville & Western NC

The Current Standard in Home Cooling

R-410A (sold under brand names like Puron) has been the standard residential AC refrigerant since the phase-out of R-22. It doesn't deplete the ozone layer and operates more efficiently at higher pressures, allowing modern AC systems to achieve the high SEER ratings that save you money on energy bills. If your AC was manufactured after 2010, it almost certainly uses R-410A.

What's Changing: The Transition to R-454B

While R-410A solved the ozone problem, it still has a high global warming potential (GWP). Starting in 2025, new AC equipment is transitioning to R-454B (Opteon XL41), which has a 78% lower GWP. If you're buying a new system now, you may encounter both R-410A and R-454B options. Don't panic — R-410A equipment will continue to be supported with refrigerant for decades, and the transition will be gradual.

What This Means for Your Current System

If you have an R-410A system today, you're in good shape. R-410A will remain widely available and affordable for the foreseeable future — this isn't a repeat of the R-22 shortage. If your system needs a refrigerant recharge, the cost is reasonable.
