Changes coming to A/C work for auto body shops as EPA phases out refrigerant HFC-134a
The Environmental Protection Agency has ordered the gradual elimination of the common refrigerant HFC-134a in automotive air conditioning systems, which means auto body shops must adjust to the new chemicals coming in its place.
Older vehicles can still be recharged with HFC-134a, but newer models will have to switch to either HFO-1234yf (R-1234yf), which some automakers are using already; higher-pressure carbon dioxide itself; or HFC-152a (R-152a). HFO-1234yf has a GWP of 4, HFC-152a has a GWP of 124, and carbon dioxide of course has a GWP of 1. At this point, it looks like HFO-1234yf will become the new industry standard.
The Robinair AC1234-6 was the first commercially available machine to fully meet the SAE’s requirement for recovering, recycling and recharging vehicle A/C systems that use the new R1234YF refrigerant. The AC1234-6 is a fully automatic ACS machine that comes with an integrated refrigerant identifier that samples the refrigerant in the vehicle’s A/C system prior to recovery, is a highly accurate and reliable machine, and can service both standard and hybrid vehicle A/C systems.
