Repair of car air conditioner: check for Freon leakage
Repair of car air conditioner starts with checking freon leakage. It is necessary to inspect all pipes and gaskets of the system for defects, measure pressure in the system. If there is none, nitrogen is connected and the reaction of the mechanism is diagnosed, depending on the level of pressure:

6 atmospheres — if it turned on, then the system is serviceable for pre-start;
18 atmospheres — if there is no leak, it is necessary to find out where the freon went;
20 atmospheres — if everything is in order, the system is serviced, which involves taking away all that is, vacuuming, adding new oil and coloring fluid, pouring freon.
After 2-3 days the client is invited for a control free inspection of the air conditioner in the car. If the leak remains, work is carried out to eliminate the defect. The client does not pay for the repeated filling with freon.

Repair of air conditioner compressor: where to begin
Repair of the compressor of the air conditioner begins with checking the serviceability of fuses, reliability of fastening bolts. In case of breakage of the drive belt, wires, fuse, replacement of the compressor is necessary.

If the mechanism makes a strong noise, monotonous humming, probably the reason is in the defects of the drive pulley bearing. Restoration of the compressor in this case is carried out by replacing the part. Before installation, the bearing should be treated with a special mixture.

Repair of air conditioner compressor: clutch
Repair of the air conditioner clutch depends on the cause of the malfunction:

refrigerant leakage — determination and elimination of causes, freon filling;
defect in electromagnet operation, absence of magnetic field — replacement of fuse or electromagnet as a whole;
mechanical errors (corrosion, lack of lubrication) — disassembly of the clutch, cleaning of its elements from rust, lubrication of individual units;
worn out bearing — replacement of the part.
Depending on the complexity of the breakage, the coupling can be replaced as a whole, or its elements are repaired/replaced.

Repair of tubes and hoses
Repair of air conditioner tubes in Curator.South Africa Repair of air conditioner tubes is performed depending on the type of breakage and brand of the car. Small cracks in aluminum tubes, the size of 2-3 mm, can be treated with special mixtures. They are applied to the formed defects in several layers.

If the holes are larger than 3 mm, argon-arc welding is performed. After welding work, the necessary piece of new hose is cut off, with the help of special cups and a hydraulic device «crimple» is made to crimp the tubes. If the cracks are very large, it is better to replace the tube.

Repair of the rear circuit of the air conditioning system
Repair of the rear circuit is done by replacing the old tubes with new ones. You can also remove the aluminum tubes and put rubber hoses instead.

When buying new hoses, it is better to choose reinforced, oil-resistant models that can withstand high pressure. The advantage of hoses is that they do not succumb to corrosion.

Radiator repair
If the damage is small, you can carry out internal or external repair of the radiator. The first option is to treat the mechanism with sealant. The second is carried out by means of cold welding or using epoxy glue. Damaged places are cleaned and processed. Large holes are preliminarily closed with a tin plate.

In complex cases, argon welding is performed. If the radiator has rusted, repair of the air conditioner in the car is impossible without its replacement.

Replacement of the dryer filter
Almost always when repairing the air conditioner in the car it is necessary to change the dryer filter. In addition, automakers recommend changing this part every year in early spring.

Repair of the dehumidifier is not effective, the mechanism will not last long. When buying a new filter, you should definitely pay attention to the presence of a fuse. Specialists recommend buying a filter in which the refrigerant level can be measured visually.

Repair of car air conditioner: summarizing the results
The process of repairing the car air conditioner begins with a thorough washing of the entire system from the inside. It is obligatory to change the filter-drier. Flushing the system is not an easy task. The compressor and other elements are disassembled. Each mechanism is washed manually with special chemistry.

If the failure of the compressor is a defect in the bearing, it can be restored by replacing the pump bearing. When the failure of the compressor consists of other parts or heavy contamination, it is advisable to replace it. After flushing, the system is vacuumized. The last step is to refuel the auto air conditioner with freon and fresh oil.

Why can not ignore the repair?

Ignoring the repair of climate control can lead not only to discomfort, but also to the appearance of unpleasant odors in the cabin, accumulation of excess moisture, increased fuel consumption, engine overheating. Therefore, the functioning of the car air conditioner should be restored in time. Such work is best entrusted to specialists.
