There’s nothing worse than climbing inside your car on a hot summer day, starting it up, and cranking the air conditioner only to discover that your vents are blowing hot air in your direction. Instead of a cool, air-conditioned breeze, you’re stuck sweating and relying on nothing more than open windows and airflow while you drive.

If your car’s AC system isn’t delivering the crisp, cold air you expect, you might be running low on refrigerant. As a critical component within your vehicle air conditioner, refrigerant can leak out or become depleted. It’s important to maintain your AC system and recharge it so it’ll keep cooling with a dose of car AC refrigerant every now and then. If you’re looking for a budget-friendly way to get your car’s air conditioner running cool once again, you’ll want to take a look at our picks for the best car AC refrigerants right now.

Best Car AC Refrigerants Buying Guide & FAQ

What to Consider When Buying a Car AC Refrigerant

Before buying any car AC refrigerants, don’t head to your local store. There are a lot of choices available when it comes to automotive refrigerants. Instead, check out our list of questions you need to ask yourself and consider before buying.

  • 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 buying refrigerant in bulk. Drivers who live in summer weather year-round will rely on air conditioners more often; drivers who live in climates with cold winters will not. Think about how frequently you need to cool your car and use that as a guide.

  • 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?

You don’t need to be a professional mechanic to recharge your car’s AC and achieve better cooling, but you do want to be properly prepared. 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!

Only you can determine your level of comfort when it comes to recharging your AC system on your own. This service isn’t too complicated, but you can always enlist a professional mechanic at a dealership or local repair shop if need be.

Car AC Refrigerant

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?

  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?

  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 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.

Car AC Refrigerant

Q: What refrigerant is used in cars?

Most of today’s cars use R134a refrigerant. It’s been the go-to choice for vehicles built since 1994 onward.

Q: How much does it cost to put refrigerant in your car?

If you’re having a dealership or mechanic do the job for you, it typically costs between $150 and $250. However, if you’re doing the work yourself, you’ll only have to pay for the refrigerant you use — and that costs between $20 and $80, depending on the product you choose.

Q: Can I use any refrigerant in my car?

It’s best to use R134a refrigerant in your car if it was made in 1994 or later. However, if you have an older vehicle, it’s best to use R-12 (freon).
