Freon™ 134a (R-134a) Refrigerant

A Hydrofluorocarbon Retrofit Refrigerant for R-12

Automotive service technicians depend on Freon™ 134a (R-134a) refrigerant, a non-ozone depleting hydrofluorocarbon (HFC) replacement for R-12. Freon™ 134a is the standard in many mobile air conditioning (AC) units, and also replaces R-12 in:

  • Commercial stationary refrigeration systems
  • Chiller systems and home appliances
  • Existing refrigeration and AC systems

Because many original equipment manufacturers (OEMs) specify polyolester (POE) oil for use, systems that retrofit with Freon™ 134a may require an oil change. Consult your OEM for specific guidance.

Regulations on the long-term use of refrigerants vary by region and application, and may change over time. For the latest information, please visit the Regulations page.

If you're looking for a low global warming potential (GWP) alternative alternative, consider Opteon™ XP10 (R-513A)—a new generation hydrofluoroolefin (HFO) refrigerant replacement for R-134a in stationary equipment.
