Depending on when your car was made, it takes either R-134a or R-1234yf refrigerant to cool its cabin. Knowing the right one to buy will help you avoid damage to your air conditioning system and other issues with your car’s ac.
The older refrigerant, R-12, is still used in some cars built before 1995. It is a non-combustible gas that helps to cool your vehicle’s cabin through a process of evaporation. It is also used in other applications like pharmaceuticals, aerosol propellants, and fire extinguishers.
R-12 was banned by the Montreal Protocol in the 1980s due to its link to ozone depletion. It was replaced in the majority of vehicles with the much safer and more environmentally friendly R-134a refrigerant, known as “freon.” R-134a is still in use today in most newer vehicles. However, some classic cars have been retrofitted to use R-1234yf, which is even better for the environment.
You can find out the type of freon your car takes by checking its air conditioning nameplate or asking a professional auto mechanic. You can also tell if the recharge hose is the correct one for your car’s AC system by looking at the refrigerant port. The ports will not fit different hoses, and using the wrong refrigerant can cause health and safety hazards and damage to your car’s air conditioning systems. You can avoid confusion by buying a freon recharge kit that contains the correct refrigerant for your vehicle’s model year.
