What Are the Different Types of Refrigerants?

The automotive air conditioning (A/C) system is a crucial component for ensuring comfort during hot summer months. An essential component of the A/C system is the refrigerant, which removes heat from the cabin and circulates cool air. Over the years, different types of refrigerants have been used in automobiles, and it's important to understand the most common types and their benefits.

  • R-12 (Freon) - This was the original refrigerant used in automotive A/C systems, and was very popular until the 1990s. R-12 has a high global warming potential, which is why it was banned and replaced by newer, more environmentally-friendly refrigerants.
  • R-134a - This refrigerant became popular in the 1990s and is still widely used in vehicles manufactured after 1996. R-134a is an HFC (hydrofluorocarbon) refrigerant that has a low global warming potential and is safe for the environment.
  • R-1234yf - This is the latest and most advanced refrigerant used in modern vehicles. R-1234yf has a very low global warming potential, making it an environmentally-friendly option. It is being adopted by many vehicle manufacturers and is now mandatory in the European Union.

When it comes to choosing a refrigerant for your vehicle, it is important to consider the type that was originally installed in the car and make sure to replace it with the same type. Mixing refrigerants can lead to system malfunctions and decreased efficiency.
