Air Conditioning Overview
Central Auto Care is adamant about keeping up with EPA regulation that forces manufacturing changes. As knowledge and technology has progressed the EPA has mandated a gradual phase out of Refrigerant 12 (R-12) due to fluorocarbons and their effects on the upper atmosphere. Prior to about 1995 almost all vehicles in the U.S. had air conditioner systems that used R-12 as the refrigerant media. Since the R-12 phase-out, the industry has used R-134A as an alternate refrigerant.
Environmental Impact Changes
In recent years the refrigeration industry has been developing new refrigerants that seek to lower Global Warming Potentials (GWP) substantially from previous products. From 2014 many cars will be switching from HFC-134A to HFO-1234yf which has GWPs 99.9% lower than the product it replaces. Manufacturers estimate that replacing HFC134a with HFO-1234yf throughout 2015 will save the carbon dioxide equivalent of removing more than 1 million cars from the road. The working pressures for this new refrigerant are nearly 4 times higher than HFC 134-A systems and HFO-1234yf is flammable.
