How to determine that you need to fill the air conditioner in the car
Content
Frequent signs that require topping up freon or oil should be alarming. This may indicate the presence of leaks and depressurization of the system.
According to manufacturers, diagnostics of the cooling system should be carried out annually. Why do you need to charge the air conditioner in the car. Whether this is a mandatory procedure, we will analyze in more detail.
Why refuel the air conditioner in the car
The air conditioning system is a closed hermetic structure that does not require refueling during normal operation. Over time, situations arise when freon evaporates or flows out. Then the owner has to diagnose and check where the violation occurred.
If the system needs to be refueled in time and corrected in time, engine wear and further costly repairs can be avoided.
The air conditioning system works not only on freon moving through the compressor. For lubrication, oil is used as one of the elements of the system. It is important to pay attention to the expiration date. Gradually, sediments form inside the product, which clog the pipes and settle on the radiator parts.
Refueling the air conditioner in the car
That is why manufacturers recommend checking the air conditioning system as often as possible. The systems of brands such as Mercedes, Toyota or BMW are considered the most sensitive to maintenance. The compressors in these vehicles keep the A/C pressure even when the A/C is turned off.
Modern cars are equipped with new generation air conditioning systems. Not only maintaining a comfortable temperature during trips, but also indirectly affecting safety, since during normal operation the windows do not fog up while driving.
The load on the air conditioner is especially high with the onset of the summer heat. The temperature difference leads to the evaporation of the technical fluid and an increase in vibrations. The lack of freon and oil leads to overheating, which affects the health of the engine.
How long to fill the air conditioner in the car
Automakers insist: it is necessary to fill the car's air conditioner annually. This will protect against breakdowns and extend the service life. The health of the cooling parts is directly related to the operation of the engine.
As for specific recommendations, I advise the auto repairman: if the car was recently purchased at a car service, then you need to fill the air conditioner in the car only after 2-3 years. An annual check and top-up becomes especially necessary when you have been using the machine for 7-10 years.
Signs you need refueling
The following factors lead to a malfunction of the air conditioner:
- external and internal damage to parts acting as seals;
- development of corrosion on the pipeline or radiator;
- decrease in the elasticity of rubber elements;
- use of low-quality raw materials;
- depressurization.
Car air conditioner diagnostics
These malfunctions lead to the manifestation of a number of consequences:
- the air inside the cabin is not cooled;
- frost appears on the indoor unit of the air conditioner;
- drops of oil appear on the outer tubes.
If you are accustomed to the normal operation of the auto-conditioning system, then the symptoms of its failure will be felt immediately. If problems are found, there are 2 options: carry out diagnostics yourself or contact a car service.
How long does the air conditioner in the car last from refueling to refueling
It is obligatory to fill the air conditioner annually from 6 years of operation of the car. In a machine of this age, a system failure can occur at any time.
New cars need refueling once every 1-2 years. The best option would be a regular preventive check of the oil and freon levels.
Drivers often ask how to fill the air conditioner in the car, and how much freon to fill. Depending on the specific system, the indicators vary from 200 ml to 1 liter. Usually, the optimal amount of refrigerant is indicated in the technical data of the machine. It is important to focus on this data during maintenance.
Refueling frequency
The procedure is carried out in the warm season on the street or on the territory of a heated box in winter. Statistically, the system fails more easily when too warm, hot weather sets in. Then it is better to check the car in the early morning.
Refueling the air conditioner in the service
Frequent signs that require topping up freon or oil should be alarming. This may indicate the presence of leaks and depressurization of the system. Under normal engine operation and the serviceability of the cooling structure, it is necessary to fill the air conditioner in the car no more than once a year.
It is not difficult to independently determine the level of freon and oil inside the system. This will be the first indicator of whether it is necessary to fill the air conditioner in the car. It is more difficult to detect a leak and find worn parts. To do this, usually seek the help of a professional auto mechanic.
