Types of Refrigerant Gas: R134a, R12 and R1234YF

There are various types of refrigerant used in vehicle air conditioning systems.   The most common being R134a but this is being phased out and replaced by the new more environmentally friendly R1234YF gas or HFO1234YF as sometimes referred to.  Air Autos is able to provide regas services for all types of gas.

For more details on each of the gases please see below:

R134a

R134a has been in use in vehicle air conditioning systems since approximately 1992 until present day and replaced the previously used R12.

R134a or to use its chemical name "Tetrafluroethene" is the most commonly used gas in motor vehicles at present.  However the R134a gas is not the most environmentally friendly gas and it is now being phased out for a new friendlier gas known as R1234YF in newer vehicle models.

It is illegal for anyone to discharge R134a into the atmosphere and any persons handling the gas requires the appropriate training and licences.

Air Autos has all the appropriate licenses as required by DEFRA and takes refrigerant safety very seriously.

R1234YF

R1234YF (HFO1234YF) has been recently introduced following updates in EU legislation and replaces R134a.

R1234YF, chemical name of "Tetrafluropropene" is considered to be significantly more environmentally friendly then R134a and has a global warming potential (GWP) of just 4 compared to the GWP of R134a of 1430.

Vehicle manufacturers are now required to design new vehicle models using a gas which has a GWP of less than 150.  Most new models therefore will be designed using the R1234YF gas.  Many manufacturers such as Kia, Hyundai, Mitsubishi, Citroen, Vauxhall, Fiat, Toyota, Honda, Ford, Landrover, Nissan, Peugeot and more already have vehicles whose air conditioning systems run on R1234YF gas.

Different equipment is required to regas / service air conditioning systems which contain R1234YF to that of the equipment used for R134a. Air Autos have heavily invested in the latest technology / equipment and are able to provide services for both gases.

R12

R12 was predominately used in vehicles pre 1992.  Its chemical name is "Dichoridifluoromethane" and it can be seriously damaging to the ozone with a global warning potential (GWP) of 2400.
R12 refrigerant is now banned in the UK. However any vehicles with an a/c system running on R12 gas can still be fixed by "retro fitting" to use R134a.

Air Autos are able to offer a relatively inexpensive R12 Retro-Fit service which takes approximately one hour and can be done at your home or place of work, wherever is most convenient for you.
