R1234YF System Charging

We can recharge and repair R1234yf systems !

HFO-1234yf  is usually pronounced as twelve, thirty-four y f. 


Originally planned to start in 2011 the start date was delayed for 2 years because the supplies of this refrigerant were so restricted. Supplies of this R1234yf are now available.


There is no requirement to convert cars built to run on R134a to use this new refrigerant, they may legally be recharged with R134a for the foreseeable future.

The only cars which must use this new refrigerant as at November 2013 are those completely re-designed since 2011 but by 2017 every new car must use this new refrigerant and if originally built for R1234yf must only ever be recharged with that refrigerant, by law.

The HFO means that it is a Hydrofluorolefin which is a complicated chemical. This HFO1234yf has been very controversial so far. All refrigerants have advantages and disadvantages and the trick is to achieve an acceptable balance. Usually its a question of balancing the efficiency and safety against the environmental acceptability. Some very efficient refrigerants with a low GWP are very flammable. R12 and R134a had similar boiling points, were not flammable at all, were extremely efficient but had environmental concerns. HFO1234yf has a low GWP and works like R134a but is very slightly flammable and this concerned some German car manufacturers, In March 2014 the EU’s Joint Research Centre issued a statement that they were satisfied that there was no serious risk with the use of this refrigerant under normal conditions.
