R1234YF Refrigerant

HFO 1234yf Refrigerant

The type of refrigerant in your vehicle will vary by the vehicle's age and manufacturer, and it is important to verify the appropriate refrigerant before performing any A/C system service. For many years, R-134a was the standard refrigerant for automotive air conditioning systems. More recently, HFO 1234yf refrigerant was introduced and was adopted by automakers as a new, more environmentally-friendly refrigerant option. HFO 1234yf has been found to create less environmental impact, and provides a 99.9 percent reduction in global warming potential (GWP) when compared to its predecessor, R134a. If your air conditioner is blowing warm air, or if you notice any leaks, it might be necessary to check for leaking fittings or components, service the A/C system, and refill the refrigerant in your vehicle. Your vehicle's owners manual will specify the type of refrigerant that is correct for your vehicle's air conditioning system, and if your vehicle was equipped with HFO 1234yf from the factory, it is the only acceptable refrigerant to use during service. O'Reilly Auto Parts carries both R-134a and HFO 1234yf refrigerant, a variety of refrigerant oils and leak detectors, and all the parts you need for your A/C repair.
