R-1234yf, you may have heard of it. If you haven’t, you will. Per new EPA regulations in accordance with the EPA Clean Air Act, R-134a will be replaced with R-1234YF refrigerant for all new cars manufactured after 2021. This is to include all new cars and light trucks built for domestic sale in the United States.
Why is this happening?
The industry is transitioning to lower global warming potential (GWP) air conditioning refrigerants at the direction of European Environmental Agency and the US Environmental Protection Agency. R-134a, traditionally used for all Motor Vehicle Air Conditioners(MVAC) systems over the last 25 years, has a GWP of 1,430. R-1234yf has a GWP of 4. What this means is R-134a is 1,430 times more harmful than CO2 in the atmosphere. How that is calculated we don’t know but it takes into account the amount of time the gas is present in the atmosphere.
