How to Choose the Best Ac Recharge Kit? 


Reading reviews about AC recharge kits alternatives will be helpful. But nothing compares to learning how you can pick the right ac recharge kit. Here’s what you should know:


Not all refilling systems for ACs come with a pump. But those that do are often way more efficient, easy to use, and fast.

Pumps are often vacuums as well. They help to get rid of the old refrigerant inside the AC tank and eventually let you pour new one as well.

Inevitably, though – a pump makes the kit more expensive. If you want to save some money, a pump-less set with self-depleting bottles will work well enough.


Then, you’ll have to consider the refrigerant. Similarly to the pump, not all ac recharge kits come with one. But it is the essential factor in the whole equation – so you’ll have to pick not only the right one but also something good enough.

Here you’ll find several types to consider. You should go for the ones that work in your car. The most popular is the R134a refrigerant.


After getting the right refrigerant, you need to pick a hose that works well with it. The hose is where the refrigerant will pass through to get into the AC, so this is critical to choose well.

Luckily, most refilling sets come with their own set of hoses. They often come with three ones, for low-pressure, high-pressure, or different kinds of refrigerants accordingly.


The gauge connects to the hoses and often come with an entire valve/manifold system. It helps to measure the PSI or pressure inside the system.

For recharging AC refrigerant tanks, it is essential to use the right pressure. Otherwise, the system may leak or break. The gauges help you prevent that and keep an eye. You should go for gauges with dials or knobs to close the system if needed.

Stop Leak

Lastly, you need to consider whether the recharging system also comes with a stop leak bottle. This additive aids in blocking any leaks from the hoses or the AC tank when needed. It seals everything to prevent refrigerant waste and make the recharge possible.

Types of AC Recharge Kit 

Types of AC Recharge Kit

Before you go and get the best car AC recharge kit, you should know what works for you and what doesn’t. And for that, it is crucial to know the different types of AC refilling systems:


This refers mostly to the refrigerant, but it is still essential to know. And R134a is the most popular and common type of ac recharge kits you will find.

Especially for vehicles, this is the way to go. If you find a refrigerant set with this type of formula, then that’s probably the one you want to pick. It is the most efficient, the fastest-cooling, and often the most long-lasting.


If you own a vehicle from under 1995 – then R12 is the refrigerant type you need. This is pretty uncommon, but it’s still possible. So, if your car is very old and needs a refrigerant replacement, then this one is probably your way to go.

Make sure it is indeed what you need, though. R12 is hard to find, you can still get it if you look well enough. According to restrictions worldwide, it is set to stop being produced by 2020.

Other Refrigerants

If you don’t want the refrigerant kit for your car, then you may need some alternative like the R-410a, R502, and similar ones. Some vehicles use other types of refrigerants as well, so be sure to get the right one for your car – or at least an ac recharge kit that is compatible with yours.

This is probably the most versatile brand you will find out there. It makes products of all kinds, going from hunting equipment to pool accessories, power tools, refrigeration items, and even fitness machines. And it doesn’t let quality behind, in any way.

AC Pro / Interdynamics

This is the ideal brand to get for your recharging kits if you want a complete experience. They focus entirely on refrigeration for vehicles and AC repair. For that, getting an Interdynamics, AC Pro or Arctic Freeze products means instant gratification.


If what you’re looking is for extra practicality, all Robinair machines will offer what you need. This brand makes recharging appliances, automotive parts, accessories and equipment for mechanics, and much more. It stands for the quality of its products, especially its recharging & recovery machines.

Frequently Asked Questions

You are almost ready to pick ac recharge kits for your home or car’s air conditioner. But first, the following answers to common doubts may come helpful – so read them up:

Q: How can I use an AC recharge kit safely?

A: All ac recharge kits vary, so they work differently. You should follow the specific instruction for each model accordingly. Overall, you just need to hook up the hose and gauges to the can, and then to the air conditioning system. Then open the valve, and it should start refilling. To stop, just close the bottle and gauges.

Q: Can refrigerants be toxic or harmful for health?

A: Yes, even though they are now safer than they ever were. You won’t get sick from breathing the refrigerant, but they will probably cause coughing, allergies, and other breathing problems temporarily.

Q: What happens if I use a wrong refrigerant in my AC?

A: While this won’t cause any damage to the air conditioning system, it will probably make it work deficiently or stop working altogether. In case the AC is compatible with different types, you may not feel a difference at all. But be careful, as most air conditioning systems nowadays are not that versatile.

Q: Should I recharge my AC every time it stops cooling?

A: No, you should only recharge if you are sure it needs recharging. Usually, it needs a refill every one to two years. So charging your AC more than that can be counterproductive or a sign the system needs other repairs.

Q: Is it necessary to do maintenance to my ac recharge kit?

A: If your system comes with a vacuum pump, you may need to keep it lubricated. For that, you will have to use the oil reservoir and make sure it is always filled.
