    AC Refrigerants

    The air conditioning in your vehicle works on the same principle as a refrigerator or home AC. They rely on a constant cycle of condensation and evaporation, and AC refrigerants are the agent that provides cooling in this cycle. When it starts getting warm outside, the last thing you want is to end up stuck in a hot, stuffy car. So, if you haven't serviced your vehicle's AC in a while, now is the time to do it.

    It is essential to maintain an adequate amount of refrigerant in the air conditioning system of your vehicle if you want it to keep you nice and cool during hot weather. Rubberized hoses and lines, O-rings and seals are slightly porous, though, and even a late model vehicle can lose as much as five percent of its AC refrigerant over the course of a year. It is useful to note that since the mid 90s, modern automobiles have switched from a more harmful R12 refrigerant to a more eco-friendly R134a.

    R12 is now difficult to come by, but if you drive an older vehicle, conversion kits are available to easily switch them over to using R134a. Once you've determined which version is suitable for your vehicle, you can pick it up here at Advance Auto Parts. You'll find we have a variety of refrigerants and AC refrigerant oil products to offer.

    You can be sure that it's time to top-up or refill your AC refrigerants when you notice that your vehicle’s air conditioning isn't as chilly as it used to be.

    If your system is leaking, many refrigerant formulations contain a dye that can make it easier to pinpoint where the leak is originating. You can easily repair such leaks using a reputable refrigerant leak sealer, also available online or at one of our stores.
