Why does a car need climate control? It cools the air, removes unpleasant odors from the cabin, absorbs moisture. Because of an A/C malfunction the engine can overheat, fuel consumption rises, and condensate builds up.
When should you visit a service center to repair the car A/C
1. if oil spots appear on the compressor surface
2. unusual noise
3. the A/C runs at reduced power or cannot be turned on at all
4. the A/C has begun shutting off frequently and unexpectedly
5. condensation accumulates in the cabin after climate control is turned on
6. the compressor runs continuously
7. musty, moldy odor
8. insufficient refrigerant
9. a component of the A/C unit is faulty
10. icing of hoses, climate-system pipes or the filter
The car air-conditioner has failed—what is the cause? It is better to anticipate problems than to deal with the consequences later, so spotting faults in time can save you money and spare your nerves. The causes may be:
1 dust collecting on the external radiator
2 contamination of the evaporator by deposits and debris
3 hoses rubbing against each other because of under-bonnet vibrations
4 oxidation of electrical components
5 late diagnostics that increase oil consumption so the compressor quickly fails from oil starvation
6 shortage of refrigerant because the vehicle was not taken to a workshop in time
Any A/C repair starts with checking for refrigerant leaks. We inspect all hoses, the compressor and other system parts, and measure pressure. If we record zero pressure, we connect nitrogen and evaluate how the system responds to pressure levels.
Restoring A/C tightness
We begin by eliminating leaks. Small cracks in metal pipes are repaired with argon welding. If cracks are large or numerous, or if vibration has thinned the pipe walls, the A/C pipes must be replaced. We fit new rubber O-rings and recommend installing a new filter-drier at the same time.

Causes:
The next step is to charge the car A/C with refrigerant
Once tightness has been restored to withstand high pressure, we fill the system with refrigerant. Before that we carry out vacuuming to remove moisture. If this step is skipped, all parts containing metal will oxidize, shortening their service life.
We always add the correct amount of oil to the refrigerant because the compressor relies on the circulating mixture.
If dust collects on the inner plates of the evaporator it causes unpleasant odors. Over time microbes and even mold can appear in the cabin. In that case we remove the trim, take out the evaporator and clean its exterior with various disinfectant solutions.
The external condenser can also lose heat-transfer efficiency when clogged. The inside of the fins can become coated, reducing refrigerant circulation. A complete internal and external cleaning of the condenser solves this problem.

Diagnostics of the A/C electronic system
This procedure is part of the comprehensive computer diagnostics. We monitor the sensors and check their serviceability
1. clean the A/C condenser of dust and dirt
2. charge only with the correct refrigerant
3. avoid overheating the body
4. periodically inspect the A/C for oil stains, dirt and mechanical damage
The air conditioner stopped cooling. The service performed diagnostics, quickly found the problem, and repaired it. Now the system works perfectly even in the heat.
I contacted them because of an unpleasant smell from the air conditioner. The technicians checked the system, fixed the problem, and cleaned everything. The air became fresh, I am very satisfied.
I needed a car air conditioner diagnosis before the summer. They checked everything, refilled it, and gave recommendations. The service works professionally.
