What is gas 134a?
R134a Refrigerant is a common refrigerant that is used in many air conditioning applications, usually packaged in blue colour cylinders. Due to the nature of R134a properties which is of a HFC (hydrofluorocarbon) refrigerant, it does not have any ozone depletion potential and has little greenhouse effect.

Can you still buy R134A?
This rule dictated the eventual phase-out of HFC refrigerants, including R-134a, across the United States. The basis of the rule was that by the year 2020, or MY 2021, all new manufactured or imported vehicles would not be able to use R-134a.

Is R134a illegal?
It has been banned by the Environmental Protection Agency (EPA). Newer Residential A/C Use R-134A Refrigerant. Starting in 2021, R-134A will be banned and phased out in a similar manner as Freon® was.
Do you charge R134A as a gas or liquid?
R134A…… Being a pure refrigerants, R134a, R12 and R22 can be charged either way. The blends like R401A, R409A, R410A and all in the 400 series of refrigerants must be charges as a liquid.
Why is R134a green?
Yes, the factory oil has a green dye – it is for leak detection.
Are all Freons the same?
There are two types of refrigerant or freon – the first one is called R12, while the other one is R134a. They may sound just like similar part numbers, but there are major differences between them.
