The flushing procedure removes oil residue, debris, and any other impurities that might have been collected over time in the AC unit. If you are buying an AC flush kit, here a few things to keep in mind:
Canister capacity: Each AC flush kit comes with a dedicated canister that holds the flushing medium. Now, a high capacity canister will surely contain more medium so that it can be used for a longer time. But, it will be much heavier and harder to carry. Hose length: The flushing needs to be done via a dedicated high-quality hose as the medium has very high pressure. You need to have a long hose for a safer operation as well as a good quality hose so that it does not leak the gas. Build quality: Similar to air compressors, the AC flush kits also carry compressed gas which is always exerting force on the inner walls. In case the canister does not have a high build quality, it might explode and cause injuries to the user.
The flush kits which are available in the market are a bit complicated and difficult to understand for a common buyer. Therefore, we are here to guide you towards your perfect purchase for the AC flush kit. Here, we are gathering the best AC flush kit available in the market right now along with its properties as well as pros and cons. We will also provide a buying guide that will surely help you along the way. Therefore, make sure you read the article until the end.

Buying Guide For The Best AC Flush Kit
A buying guide is a very helpful set of instructions that guides you to get the best product available in the selection. As we are talking about the best AC flush kits and you will most probably get one of our top picks, we are providing this buying guide that will help you to narrow down the best option regarding your needs. Before proceeding with the buying guide, you must read each and every single product carefully otherwise you cannot understand the properties mentioned in the buying guide as they vary according to each product. If you are already considering a couple of options, make sure they have the following properties:
1. Cleaning capacity
Every AC flush system kit varies marginally in terms of properties. Hence, you can surely expect a lot of difference in the end result. As you may already know, different AC systems run on different refrigerants. As refrigerants are basically various chemical compounds, each refrigerant leaves a different sort of trace behind. And to clean such a system, you need a particular pressure or solvent for perfect results. Now, you can either check the properties of the refrigerant used in your system and compare it with the flush unit. Or, you can simply take a look at which refrigerants are supported by a particular flush system for a quick decision.
2. Hose length
Operating with a high-pressure gas can turn out to be very hazardous. Especially in case of AC flush systems as the pressure limit is around 170 PSI in some cases. Such high-pressure flow is fairly difficult to control. Therefore, you must have a long hose so that it does not slip out of your hand while it is being operated at full potential. Also, a long hose can easily reach any part of the cleaning unit without needing to move the whole flushing unit to the other side that comes in handy if you are a frequent user.
3. Canister size
The canister size is generally specified in ounces for every product. It is basically the amount of pressurized air a certain flush system can hold while maintaining a certain pressure. Now, the higher the capacity, the longer it can be used without needing a refill. Refilling the canister is rather a tedious task as you will have to go to a dry air shop to get it done. And if you are adding up certain high-end solvents as well, you will have to pay a bit extra as compared to the dry air mixture. Therefore, make sure you get a high capacity canister so that you don’t have to go through this tedious process frequently.
4. Build quality
Build quality of the flush system is another important aspect that should not be overlooked while buying one. The build quality is solely responsible to prevent any hazardous accidents because of overpressure or mishandling. The overall build quality consists of the build quality of the canister as well as the hose that is used for spraying. The canister is holding all of the pressurized gas insides. Therefore, it must have high durability as well as high corrosion resistance as corrosion weakens the surface of the metal.
5. Reliability
While buying an AC flush system, you should look for the most reliable option available in the market. The reason behind this is that the flush unit will be carried alongside your vehicle at all times. Hence, it will undergo constant vibration and impacts. Now, to ensure it does not fail because of this, it should have a sturdy build quality. To ensure the reliability of the product, take a look at the warranty period allotted by the manufacturer. Usually, heavy-duty products carry a longer warranty period as they have a decent build quality and are less likely to fail any time soon.
Conclusion
If you live in a dusty region or love offroading in your car, you will definitely need a decent AC flush kit always by your side so that your AC system does not stop working overtime. Instead of paying various charges to get your AC system cleaned up, you can take matters into your own hands and completely clean the system whenever you feel a discomfort in the performance.
