What Is R134a Refrigerant?

R134a (also known as HFC-134a or 1,1,1,2-Tetrafluoroethane) is a hydrofluorocarbon refrigerant widely used in:

  • Car AC systems

  • Refrigerators & freezers

  • Vending machines

  • Small chillers

  • Residential dehumidifiers

  • Commercial refrigeration

It became the global standard replacement for R12 in the mid-1990s due to its zero ozone depletion potential.

Is R134a Still Legal in the USA? (2025 Update)

Yes, R134a is still legal to buy and use in the United States, but regulations differ depending on the type of use.

Automotive Use (Car AC)

You can buy R134a without certification if it is packaged in small retail cans designed for vehicle AC recharge.

Bulk Cylinders

Buying full-size refrigerant cylinders may require EPA certification depending on the application and local regulations.

Phase-Down Status

R134a is part of the HFC phasedown program under the AIM Act, meaning supply will gradually decrease over time. This may increase pricing in the future, making reliable sourcing increasingly important.

Until around 2017, nearly all U.S. cars used R134a. Millions still do today.

Commercial Refrigeration

Many beverage coolers, vending machines, and display cases still rely on R134a.

Home Appliances

Certain refrigerators and portable AC units use R134a as well.
