FJC 623 Refrigerant
Gone are the days of fumbling around your vehicle’s AC system with nothing but a tiny UV light searching for leaks for hours on end. FJC’s top-quality refrigerant combined with UV lighting makes it so much easier to identify and fix a leak. The purchase even includes two dyes; a light green dye for daylight visibility and a fluorescent dye which shows up as orange under UV light.
Before using the dye, vigorously shake the can or turn it upside down near the end of the charging process. This is because the dye is oily and could potentially add more oil into the system if not treated properly. Don’t worry, this all sounds pretty complicated, but we promise that this product is both easy-to-use and works a treat!
Top Tip: Once applied, the dye will not dissipate by itself. You must afterward clean the dye off from where the leak is located.

Best Car AC Refrigerants Buying Guide & FAQ
What to Consider When Buying a Car AC Refrigerant
Before buying an AC Refrigerant, there is a list of steps you need to mentally check off before making the purchase. Below is a list of questions you need to ask yourself before making your choice:
- How much refrigerant are you going to need?
Firstly, what kind of climate do you live in? You're surely going to need more refrigerant over a period of time living in Texas or Florida than you will living in North Dakota. If you're one of the lucky ones who are most blessed with sunny weather, then consider refrigerant in bulk, such as Johnsen's economical 12 pack of R-134a.
- What kind of vehicle will you be buying this refrigerant for?
Next, it's time to think about your specific vehicle. Many people are unaware that hybrid models cannot take the same kind of refrigerants than your average car. Brands such as Interdynamics have thankfully released refrigerant for hybrid models.
- Do you have all the required tools?
First things first, you'll need to become familiar with the tools that will be used to protect you first such as safety goggles and gloves, so the refrigerant doesn't harm your bare skin.
We recommend investing in a reliable gauge set. These are used to read the high and low side pressures in an AC system and to recharge the system with refrigerant. This is too complicated a procedure to complete blind-sighted and unprotected!
- Are you skilled enough to do this job?
Although many dealerships get a bad rap for setting very high prices for small jobs, the large majority are trustworthy and ready to help. If you know that attempting to change your refrigerant alone could end disastrously, it's ok to get help!
Why Does Your Air Conditioning Need Recharging?
In most cases, your air conditioning needs recharging simply because it runs out. You can then decide to deal with this yourself or ask a professional.
However, sometimes your air conditioning shuts down as your car's AC has a leak. Your car isn't trying to further punish you by shutting down the air conditioning because of a leak, it's trying to save you from additional hassle. If a leak in a hose or anywhere else occurs in the AC, most modern vehicle systems are designed to shut down once the refrigerant reaches a set level so that the air-conditioning compressor will be protected. This is not an invitation to ignore the problem, serious damage may occur if you try to overlook the leak.
Types of Car AC Refrigerants
The difference in refrigerants is all down to how old your car is. There are two types of refrigerants used: R12 and R134a. R12 is known as the old-fashioned refrigerant and was used in cars pre-1944. As you can imagine, this Freon had a major role in damaging the ozone layer. It's no longer available for casual purchase, no longer manufactured in North America and will have to be fitted by a professional. Likewise, the price of R22 has absolutely skyrocketed and this refrigerant won't be accessible for use at all by 2020.
If your vehicle was manufactured after 1995, like most cars it will require an R134a refrigerant, which is a less harmful alternative to the R12 systems. These systems don't leak nearly as much as the dinosaur systems and are a lot better for our planet.
NEVER mix different types of refrigerants together. You'd think this would be common sense but there's always somebody who doesn't see the problem with this! By doing this, you're pretty much asking for a fire in your vehicle.
Best Car AC Refrigerants FAQ:
Q: What is a Car AC Refrigerant?
A: Car AC Refrigerant is what keeps us from melting alive when driving about on horrifically hot summer days. Stating the obvious, AC is short for air conditioning and the refrigerant is a substance or mixture used for cooling. Lots of people refer to a car's AC Refrigerant as Freon, which is actually a registered tradename that describes a whole class of chemicals used in refrigeration. In other words, it's a coolant which is responsible for creating the cool air. DuPont uses the term Freon as the brand name for Chlorofluorocarbons (an organic compound) and it's pretty obvious why considering that this term is impossible to pronounce! Don't lie, you just tried to pronounce it, didn't you?
Q: Is a Car AC Refrigerant Dangerous?
A: 100%. When it's the middle of winter and an AC leak occurs, a large majority of us won't bother our shirts changing the refrigerant; it's not like we'll be using it, right? However, what many people fail to consider is that changing your AC isn't all about being at a comfortable temperature while driving, it's about the toxic air that you and your family will be breathing in until you get around to doing so.
There is such a thing as refrigerant poisoning, which occurs when vital oxygen is cut off from entering your cells and lungs caused by deeply inhaling Freon. It is similar to carbon monoxide in that Freon is a tasteless and mostly odorless gas; you simply don't know that you're breathing it in.
Another common and foolish usage of Freon is for getting high. If you respect your health at all then don't bother. Air is pretty much the only thing your lungs like to be filled with.
Q: How often does an AC system need to get recharged?
A: A common error that many drivers make is thinking that they must recharge their air-conditioning system every couple of months or so. This is simply a 'white lie' that somebody invented to try and encourage buyers to invest in refrigerants. In fact, you only have to worry about topping up your refrigerant every couple of years. We'd recommend starting to think about recharging your system around the two-year mark.
It's pretty difficult to identify if your car has a leak. A few things you can look out for is how your defroster reacts in the winter; if it isn't clearing fogged-up windows, this is a sign. But the number one most obvious sign that you need to top up is when your car's air-conditioning system only blows warm air.
