Besides the fact that R-1234yf and R-134a are out there, and we need to be aware of those differences, the A/C system on some hybrid vehicles remains an area of concern.
We’ve been getting an increasing number of questions regarding the procedures, OEM requirements, and general cautions related to the evacuating, recycling, and charging procedures required for servicing the air conditioning (A/C) systems on hybrid vehicles using R-134a (aka HFC134a). These are the systems that have high voltage (HV) electric compressors rather than the conventional belt-driven types that we have been working on. Although there are many issues related to HV electric compressor systems that need to be understood.
