A/C Compressors: Why the right oil matters
A/C Compressor oil is the biggest cause of product failure.
Maintenance and repair of automotive air-conditioning (A/C) units, either manually or automatically controlled, represent a real expansion opportunity for garages and workshops. Indepth technical knowledge of A/C systems, common faults, recommended components and oils are all essential to achieve customer satisfaction and build return business.
Central to this technical know-how is a comprehensive knowledge of compressors. This is because 99.9% of all compressor problems are not related to product failure, but from a poor understanding of A/C system operation, maintenance and repair.
But there is one aspect in particular that causes the majority of avoidable A/C Compressor problems is the oil.
Universal oil: a key cause of compressor failure
Compressors are vital to a vehicle’s A/C system; compressing the low temperature, low pressure gaseous refrigerant from the evaporator, into a high temperature, high pressure gaseous refrigerant, and discharging it to the condenser.
Oil in the A/C system is essential, primarily to lubricate moving parts, i.e. the compressor and the expansion valve needle. It also enables heat to escape from the compressor. As with refrigerant, oil in the A/C system must retain its chemical stability.
However, it is vital to choose the right oil for the job. Insufficient lubrication due to universal oil is the second most frequent reason for A/C compressor damage and failure.
What are the pitfalls of universal oil?
The use of incorrect oils, such as universal oils or oil mixtures, inevitably leads to A/C compressor damage. This is because universal oils, often preferred by garages, are PAO-oils, or mineral oils with a different viscosity than synthetic PAG-oils. The difference between these two types of oil means that they do not mix, leading to poor lubrication, damaged seals and increased wear.
If the oil is diluted, the lubricant base layer decreases. This results in the piston rubbing against the cylinder bearing surface. If the oil is too thick, it is unable to ‘squeeze’ between the cylinder and the piston. change in the oil viscosity can result in more frictional resistance, leading to an increase in compressor temperature and subsequent seizure.
Blending or mixing of different types of oils may lead to the formation of paraffin. This can block the flow of the refrigerant and oil, leading to seizure of the compressor and system failure.
Quantity as important as quality
It is not only the quality, but the quantity of oil in the system that is of great importance. Too little oil leads to poor lubrication of the compressor, rising component temperature and oil scorching on the suction side of the compressor. Too much oil in the system will increase the load on the piston-crank system, which can lead to a block in the body of the thrust bearing and the hard front piston co-pivotable skid plate.
Is the oil filtered?
It is also essential that any solid impurities in the compressor oil are removed in the filter-dryer. The filter-dryer will also capture moisture from the oil. As part of the annual maintenance of the A/C system, it is equally vital to remove a proportion of the oil, replacing it with the same quantity of fresh oil.

We are running free leakage diagnosing test this week offer end 11/3/2016

I refilled my A/C gas like a week ago, was driving down from Marina to Ikorodu last night and it was working perfectly until I got to mile 12 and I didn't feel the coldness again, switches it off and on thrice, still no changes. Before it was refilled the technician that worked on it last year told me there's a rubber ring that leaks it, so he traveled out the new guy I gave it to I told him about the problem and he said he changed it, I'm so furious now, cos it's frustrating going up and down a service workshop. What could possible be the lasting solution to this?

The Importance of Car Air-Conditioner Maintenance
by mosbus cool
If your car has an air conditioner, and it most likely does, then it is important to get routine maintenance done on it. Many people don’t think much about their car air conditioner until they need it and it’s not performing correctly. But the best way to keep it performing at its best is to get routine maintenance done as needed.

Routine maintenance is important for every car air conditioner for several reasons, including:

• Keeping it cool. There are a number of problems that can lead to an air conditioner not working as well as it should. Before it becomes a problem these issues can usually be addressed through routine maintenance. That way you never miss a beat in the heat.
• Keeping it clean. When you have a clean air conditioning unit you will help to keep it in good running order. Routine maintenance will keep the hoses and belt clean and running as they should.
• Keeping it from getting worse. Routine maintenance on your car air conditioner will help us catch problems right away, rather than them compounding and getting worse. The sooner you can catch and fix a problem, the better off you will be in the long run.
• Keeping up the value. You paid additional money to have an air conditioner in your vehicle. The good news is that it will help keep the value of your car up if you take care of it. Once you go to sell the vehicle it is a plus if you can demonstrate that you have had routine maintenance performed, including having it done on the car air conditioner.
• Keeping you comfortable. One of the best reasons to keep up on air conditioning maintenance is so that you can actually enjoy the cool air. Being able to beat the heat on a hot summer day is worth the little bit of effort it takes to keep your car’s air conditioner maintained.

The good news is that routine maintenance and inspections on your car’s air conditioner is as simple as giving the Keepin’ Cool Auto Air-Conditioning Specialist a call. We are fully equipped professional.

The importance of maintaining your car’s Air Conditioning

Automobile air conditioning systems are complex and often require help from a reputable service and repair center. Air conditioning systems include control system, vacuum lines and the refrigerant system. Although there can be multiple reasons as to why the air conditioning does not work anymore, the most common reason is because the interior of the automobile will not cool to a comfortable temperature.

Because the air conditioning system is complex, it is important to take it to a specialist. Automobile repair specialist can diagnose the problem through a series of checks that they perform. While some problems can be easy to fix, others can be more complex to find and resolve. Auto service and repair centers use special equipment including leakage detector kit tools to check for air conditioning leaks which can be hard to find because they are virtually invisible. Other tests administered by automobile professionals include checking the condenser, compressor and the cabin filters.

To ensure that your air conditioning is functioning properly run it every two and a half week for a few minutes. Check that your system sends cool air and warm air. If your air conditioner is giving you trouble drive over to mosbus cool, we will be happy to help you get a cool deal on your car repair.

If you condenser is mouldy go and wash it up in car wash,but if the same fault persist check the gas level.

How do we know the type of oil and quantity. My 2004 honda accord i4 compressor I bought and used for a week heat up and burnt the clutch. The former compressor leaked through the pipe with the oil and burnt very badly needing a new one. Nowthe latest one burnt but I think it's only the clutch that's affected. Pls what's the oil type and quantity. The last was using green oil and new one transparent oil was used. And we can't find someone profess thats can vaccum here at anambra Nnewi

Hello,

thanks for the prompt response. Condenser was replace of recent, Gas was also refill 2weeks back.

Use ND 8 or pag 46 for the lubricant oil and for the gas quantity is between 500-600gram max.seems the technical doesn't have vacuum machine let him fill the gas without starting the car,.

What of quantity of oil to use?

Namzy:

What of quantity of oil to use?

oil quantity is 130ml

Had my compressor, condenser and dryer changed recently. The Ac was cooling fine and is still cooling fine especially in the morning and evening but I Observed recently that when I switch on the Ac sometimes, the light on the switch will start blinking. I will have to switch it on and off for some time before it will pick. What could be the cause? It is not all the time anyway. It's a camry 1999. Thanks in advance for your response.
