How to choose air conditioning filling equipment?

As summer approaches and thermometer columns rise, many car or other vehicle owners rush to fill their vehicle with a new refrigerant. It is really quite convenient for drivers to use this service at the moment, as there are many car repair shops in the cities that can offer this service. Also, the air conditioning refill service during this period is available at major supermarkets and there are even offers to arrive on site. It is easy to find even companies that specialize only in refilling air conditioners and provide their services to larger companies if they have large fleets or a large number of employees who come to work with their cars.

It is common for us for car manufacturers to set intervals for their vehicles to change operating fluids and parts every few kilometers or time, such as engine and gearbox lubricants, coolant, cabin or oil filters, and more. But Freon is one of those for which there is no set interval and it is not usually necessary to change it if the car’s climate control system itself works flawlessly.

How to check the tightness of the car air conditioning system?

Refreshing the refrigerant is not necessary in the car, but the most important thing is that if you still need to refresh the freon in the car, you need to look for the reasons why it is missing. If the system in the car is in order, the amount of refrigerant in the system does not change. For example, home refrigerators work on the same principle and we don’t carry refrigerators anywhere if everything works fine. It is also the case with cars, if the internal system is leaking, the addition of a refrigerant is being done at that time, but it also means that the system is not in order either.

When properly filling the entire air conditioning system, it is necessary to check for leaks both before and after filling. The fixed system pressure must be checked before filling the car air conditioner. If the pressure falls within the proper range, no further leak testing is required as the system is operating properly. If the pressure is low, nitrogen gas is blown into the system at a pressure of 10-17 bar (you can do this with the nitrogen test kit, click here). Separate pressure measuring tools are provided for this, so if no pressure difference is visible, the car mechanic must listen through where the gas is sizzling. We recommend that you even buy a UV flashlight and goggles to detect air conditioning leaks.

If the leakage in the car's climate control system is very minimal, the pressure drop will also be very small accordingly. You can then help you by adding paint to the refrigerant. There can be a variety of ways, as well as devices to detect A / C system leaks are very diverse, all the necessary system air conditioning system tightness equipment can be found here.

The EU regulates the use of refrigerant

The use of Freon conditioner filling has been strictly supervised and regulated in the countries of the European Union. Only companies with a quota can bring a refrigerant into the EU. Also, there are strict requirements for who can work with freons, and there are courses that lead to a certificate. Since 2017, it has been decided that new cars using the old R134a freon will no longer be imported into the countries of the European Union.

The European Commission has decided that R134a freon will be phased out altogether, leading to a reduction in quotas, which is making R134a freon increasingly expensive.

All this is due to the increase in the ozone hole. However, there is another freon, R1234yf, which has a much lower environmental impact. The retail price of this freon in the retail market fluctuates around 500 euros per 5 kg. The capacity of the air conditioning filling system in cars varies, but usually ranges from 400 to 500 grams. So it is easy to calculate how much, with one freon tank, it will be possible to add car air conditioning filling systems on average.

In order to engage in legal and professional activities, it is necessary to complete special training in filling and servicing air conditioners. Such training is intended for mechanics and professionals of various vehicles who work or want to start working with air conditioning systems. During the A / C service, the participants are introduced to the system, freon types, their implementation and utilization, how to repair the systems, acquainted with the technical knowledge of compressors, clutches, valves and filters, about the operation of pumps and their types. All such training is conducted by competent professionals, after which such training is followed by a subsequent test and finally a certificate proving that the participant has all the necessary knowledge to provide professional services.

Car refrigerants (freons) and their use

A refrigerant, also called a freon, is a substance that is added to a car
