If you're searching for R134a refrigerant for automotive AC systems, home appliances, or commercial refrigeration units, you're in the right place. R134a remains one of the most commonly used refrigerants in the United States, especially in vehicle air conditioning and small cooling equipment.

This guide covers everything you need to know in 2025, including where to buy R134a, whether it’s still legal, how much you need, and why CoolMateGas is a trusted refrigerant supplier.

 

 

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 (12oz / 14oz) designed for vehicle AC recharge.

✔ Bulk Cylinders (10lb / 30lb / 125lb / 950lb)

Buying full-size refrigerant cylinders requires EPA Section 608 certification, just like other HFC refrigerants.

✔ Phase-down Status

R134a is part of the HFC phasedown program under the AIM Act, meaning supply will gradually decrease until 2036.
This will slowly raise the price — so securing supply at a good cost matters more than ever.

 

 

What Is R134a Used For?

Automotive Systems (Most Common Use)

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.
