R1234YF Basics

R12 Freon was banned in 1996 because of environmental impact and evidence that it was helping to create a hole in the ozone layer of the Earth’s atmosphere. It was replaced with R134a refrigerant that is still used in some older vehicles today. Then, it was discovered that R1234YF has an even lower impact on the ozone layer and today it’s currently being used in most newer cars. It’s important to know that currently, you can’t retrofit an R134a auto AC system to use R1234YF as they are not interchangeable.
