Dangers Of DIY Car Air Conditioning Recharge Kits

Posted August 9, 2017

Since the summer is here, one of the more popular things for car owners to try to do themselves is to recharge their auto air conditioning unit with a store bought recharge kit. While this may seem for the typical owner to almost be too good to be true, let us tell you some facts around these kits.

Dangers of AC DIY Recharge Kits

One of the biggest issues with these kits is that they do not get rid of the fluids and refrigirants that are still are in your system. They merely add refrigerant to what is already there. Sort of like topping off your engine oil. While on the surface this might seem a good thing, but this doesn’t address the root cause of your issue and may even lead to more problems down the road.

AC Refrigerant Leaks

A little known fact is that AC refrigerant does not evaporate, but rather it leaks. So, if your system is low on fluid, that means you are leaking that fluid right into the atmosphere, potentially causing harm to the ozone. Especially if you are in an older vehicle (using CFC-12) this can cause serious environmental harm. In fact, this refrigerant itself isn’t allowed to be produced in the United States anymore due to the issues it causes with the environment.

AC System Contaminants

Different contaminants can leak into your AC system, such as dirt, grime, and dust. This in turn can cause different components of the system to clog, causing further damage and limiting it’s ability to cool your car down.

Since manual recharge kits only refill your system, it can leave water and those other contaminants still inside of it. In fact, when water is mixed with refrigerant it can do something known as hydrolize, forming hydrochloric and hydrofloric acid which eats away at different parts and creates sludge clogging the system.

Mixing Different Auto AC Refrigerants

It’s never safe to mix different types of refrigerant together. This can cause unsafe chemical reactions and potentially damage the compressor or other parts of the system. Especially if you do not know exactly what kind of refrigerant you are using, then make sure to bring your car to an ASE certified technician to have it checked out before you use one of these recharge kits.

Other Air Conditioning System Issues

Typical with many of the recharge kits, they claim to be able to fix current and prevent future leaks. Unfortunately, usually the sealant they use doesn’t work or if it does, it tends to clog other parts of the system as well, creating bigger problems for your vehicle.
