Puron

About Puron

Puron is the brand name for Carrier's widely used R-410A refrigerant, developed as an environmentally friendlier replacement for earlier refrigerants such as R-22. Traditionally used in residential and light commercial HVAC systems, Puron (R-410A) is a hydrofluorocarbon (HFC) with no ozone depletion potential, offering improved efficiency and reliability for air conditioning units. As regulatory standards evolve, Carrier is phasing out original Puron in favor of Puron Advance (R-454B), which features a significantly lower Global Warming Potential (GWP) and aligns with upcoming environmental mandates. Puron remains a key name in HVAC refrigerants during this transition.
