Freon™ Refrigerants for Medium- and Heavy-Duty Vehicles

Modern AC Refrigerants Enable Efficient, Safe Transport

Air conditioning (AC) used in medium- and heavy-duty vehicles provides a comfortable cabin environment and plays a critical role in safety for:

  • Delivery trucks
  • Shuttles
  • Interstate tracker trailers
  • Emergency response vehicles (e.g., ambulances and fire engines)

Cabin comfort helps maintain driver concentration to ensure goods and people are transported safely. Reliable, energy-efficient AC systems are essential for these heavily used vehicles that often travel considerable distances.

Until the late 1990s, the chlorofluorocarbon (CFC) refrigerant R-12 was the most widely used refrigerant in these systems. Since the industry's shift to using non-ozone depleting refrigerants, however, the hydrofluorocarbon (HFC) refrigerant Freon™ 134a has become a reliable and effective alternative to R-12. While modern vehicles have AC systems that use Freon™ 134a, antiquated mobile AC systems have been retrofitted to use R-134a.

Long-Term Use Considerations

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

Low GWP Alternatives:

Chemours has developed a new generation of low global warming potential (GWP), hydrofluoroolefin (HFO) based refrigerant replacements for Freon™ 134a in new equipment. Learn more about Opteon™ YF.
