Causes of Damage and Solutions to Repair Car AC Compressors
The following are all the ins and outs of car air conditioning compressors and common damage experienced along with solutions to your car ac compressor problems.
Did you know that Indonesia is the Largest importer of car compressors in Asia, and the third largest compressor importer in the WORLD.
Great is not it? Indonesia is a developing country where automotive is a part of everyday life. Maybe because the weather is average in Indonesia, which is classified as hot, car air conditioning is the main requirement of all car users.
Just imagine, often when the car air conditioner is not cold that the workshop recommends to replace is the AC compressor. Why? It could be because the price is expensive and the workmanship is relatively easy. It could also be because technicians who do not understand the theory of the car ac system think that the most important parts must be replaced. Of course you as a consumer do not want this to happen. Therefore, our car doctor will explain the types of car ac compressors and the signs that the ac compressor cannot be used anymore, so you can get the right diagnosis before making the decision to replace the most expensive ac parts.
There are various types of car air conditioner compressors:
PISTON type
This type is the most used and the most durable. The piston type has a swash plate which is used to drive the pistons to produce pressure and compression so that the car ac system can function optimally. This type requires a car AC compressor oil to lubricate the iron parts that rub together like a car engine.

Scroll type or snail
This type of compressor uses a conch-shaped rotation and plate to push and put pressure on the existing freon, this type is quite resilient because not many metal parts rub against each other, but if the compressor oil is reduced, the compressor will heat up and will burn the other part is like a clutch magnet.

Wobble plate type
This type of ac compressor is almost similar to the piston type. But this type has a larger and more dominant wobble plate used to pump the existing freon, this type is more easily damaged than the piston type.

Blade Type
This type is the most frequent problem, if the AC compressor oil in the car is reduced then the blade that sticks to the compressor wall will be scratched and damaged. When the compressor blisters will make a snoring sound and the freon pressure will be much reduced so that the air conditioner is not cold.

The type of compressor for each type of car is different. But all types of ac compressors require precise OLI and Freon ratios or comparisons to produce the perfect ac compressor performance. Because if the compressor oil is too little or already bad then even the lubricating power will not be perfect. This will cause blisters or wear on the car ac compressor parts.
When the moving ac compressor is scratched, it will cause two things, the first is the non-standard freon pressure so that the freon does not reach the optimal heat point, this will affect the reduction in the evaporation of the freon in the system so that the cold released is not optimal.
The second thing is the grams of iron produced by friction from worn parts will be pushed to the condenser and drier causing a blockage which will eventually aggravate the condition of the existing compressor, even if it is too severe the compressor that has just been replaced will also be damaged due to the blockage. Therefore, in some cases that are too severe, we recommend replacing the condenser and drier as well. As explained in the video below:
If Not Treating the AC Compressor
Because of the small hole of the freon duct in the condenser it will be very difficult to clean. so the possibility to clean thoroughly is very small. Welding when leaking which serves to patch also serves to clog, because the hole is very small when it leaks many workshops that suggest to be welded only or patched, this MAY be able to patch the leak but will also close the hole, the result is abnormal system pressure aka too high, just try to imagine that there were for example 10 lanes for freon now only 9 lanes left, the choice is the same number of freons for maximum cold but will overload the car AC compressor more, or the number of freon reduced so that the pressure according to the standard but the cold is decreasing because there is not enough freon. So it is not recommended to weld or mena

leakage in the condenser or evaporator.
Car air conditioner compressor oils also have several types but for in Indonesia there are at most three types:
Viscosity <50
This type is most commonly used for cars:
Toyota / Daihatsu / Lexus:
Ayla / Agya
Avanza / Xenia
Calya / Sigra
Rush / terios
Innova / deer
Fortuner / Hilux
Harrier
Camry
Vios
Yaris
Altis
Alphard
Coopen
Land Cruiser
Sienta
Corola
Mark x
CHR
All types of Mercedes Benz, BMW, AUDI, Volkswagen, Isuzu, Mitsubishi, HONDA
Viscosity <110
Nissan:
Livina
Elvira
Evalia
Juke
Xtrail
Chevrolet
Captiva
Aveo
Viscosity> 110
Chevrolet colorado, and several types of FORD
Where if improper viscosity is entered into the ac system, the compressor will work heavier or not well lubricated. Provides shorter compressor life and is easily damaged. Therefore, if your AC workshop considers ac compressor oil to be just a lubricant, it can be ensured that the workshop cannot do your car's ac precisely. It might not even be damaged more than before. Of course you don't want to, right?
The Process of Changing the Oil Compressor of Car AC
Different types of oil will also DEFINITELY damage the ac compressor of the car, just try to imagine if your car's engine is filled with cooking oil, both are slippery but have different functions. Surely there will be severe damage after use.
The type of freon loaded also affected the performance of the car ac compressor, above 1995 the car manufacturer agreed to use the new R134a freon which was more environmentally friendly than the previous freon R12 and R22. Where the R134a freon is not as cool as the previous freon. But R134a freon is not dangerous when inhaled by humans, while Freon R12 is poisonous if inhaled. This is very dangerous for adults and children in the car.
Older Freon models are more accidic or acidic than R134a and therefore, many traditional workshops do not know this and mix it up to get maximum cold, even though the wrong freon type will cause severe corrosion in the car ac system. Car Doctor has a tool to check the type of freon in your car, so we can GUARANTEE the freon that is loaded in accordance with your car.
The type of freon cylinder used is also important. Why? In Indonesia, there are 2 types of freon tubes in circulation, namely 13kg large tubes and 350gram small tubes,
Where a large cylinder containing a R134a PURE freon without a mixture of oil or other gas, this type of freon the car doctor uses so that we can guarantee the accuracy of filling the compressor oil of the car, so that even the maximum cold.

The small freon cylinder contains the compressor's OLI so that when it is filled the ratio of freon to oil changes immediately. Therefore we don't like using a small freon tube.

Leaks in the car air conditioner system can also interfere with the compressor's work, especially where the compressor has been filled in Freon several times, why? Freon in car ac systems contains compressor oil, where if the freon is leaking, compressor oil will be reduced as well. If this is done continuously, the compressor will work with less oil which causes blisters or worn parts.
To find out whether your car ac compressor can still be used or not, the first thing to check is the compressor pressure, if the pressure is still in normal limits with enough freon, then the car ac compressor should still be used. The point is that as long as the car can still cool if added freon, then the compressor is still working well, for more details you can contact the car doctor's customer service when checking your car for FREE and ask about DOMO TOUR, where our Customer service will explain the compressor criteria broken in detail .
Many of our customers complain that the car air conditioner is only cold when it is on the Gas or is running. To check this we must ensure that your car's cooling system is working properly. So we can isolate the problem to the ac compressor only. Now if one of the Low pressure is too high, and only goes down when in gas. So we can be 100% sure that the compressor has blisters and can not do its job optimally, this is because the blisters of the compressor can not provide optimal pressure when the engine IDLE alias lang sam, and must be raised its RPM before the ideal pressure can be reached.
Car AC Compressors are totally broken, usually indicating the clutch magnet is burning red, because the magnet is still working when the ac compressor is stuck, so that the iron rubs against the compressor pulley and generates heat which then burns the magnet, the most important indication is the AC compressor oil.
