Introducing Puron Advance™
Carolina Air will be using Puron Advance™ in all new Carrier’s home comfort systems installed in 2025. This new refrigerant replaces Puron™ in all residential systems. This innovative refrigerant, also known as R-454B meets the Environmental Protection Agency’s (EPA) anticipated Global Warming Potential (GWP) limits for refrigerants and the scheduled phasedown of higher GWP refrigerants like Puron™ or R-410A.
What does refrigerant do?
There are many different kinds of refrigerant, but they all do the same thing. As a part of your air conditioner or heat pump system, refrigerant helps transfer heat and humidity out of your home for cooling. It also draws heat from outdoor air and brings it inside for heating. Your system uses the refrigerant over and over again, as it cycles through. It is not like gasoline or propane fuel which always get used up to provide energy or heat. However, you can lose refrigerant over time through leaks in your system.
Why are refrigerants changing?
There is strict control over the Global Warming Potential (GWP) of refrigerants. Since January 1, 2025, the EPA no longer allows manufacturers to build residential ducted and ductless HVAC equipment using the previous R-410A (Puron) refrigerant.
What If I have a system with an old refrigerant?
The new refrigerant will not work on a system designed to run an older refrigerant. Carolina Air will continue to service and maintain your system with whichever coolant it is using, for as long as possible. The older refrigerant will be available for repairs and maintenance for many years. You do not need to worry about trying to remember which type of system you have – we’ll take care of that for you!
