Hydrofluoroolefin (r1234yf refrigerant)

R1234yf is a hydrofluoroolefin (HFO) refrigerant. HFO refrigerants are composed of hydrogen, fluorine and carbon atoms, but contain at least one double bond between the carbon atoms. Due to its composition, R1234yf does not damage the ozone layer or has minimal global warming impact.

R134a and R1234yf are similar, however, R1234yf was created as a more environmentally friendly replacement to R134a. The biggest difference between the two, is that R1234yf is mildly flammable and does require special handling. Diagnosis of the air-conditioning system can be done in the same way as with R134a.
