Top Preventive Measures For Auto A/C Compressor Failure
Auto A/C compressor failure can result from a number of causes. The good news is that many of these issues can be prevented by regular maintenance. Below are some ways to keep your compressor working in optimal condition for as long as possible.
The Suction Lines Are Blocked
When the refrigerant lines are blocked, the air conditioning won’t be able to cool as efficiently. Should the problem worsen, the rising temperature and pressure will lead to overheating which can cause the compressor to fail completely. To stop this from happening, it is important to make sure the suction lines remain unobstructed at all times.
Many automobile enthusiasts think they can replace their A/C refrigerant themselves in order to save a buck, but they often underestimate the complexity of the process. If too much refrigerant (or too little) is added, this will cause problems, as will adding the wrong type, since this will damage the compressor. Unless you’re qualified to handle refrigerant, it is best to have the refill done by a licensed technician.
Contaminants Are Present In The A/C
Air conditioners are subject to elevated pressure and heat, and due to their exposure to the surrounding atmosphere, a number of contaminants can enter their systems. These unwanted particles include moisture, dirt, debris, soot, leaves and acid, and if left unchecked can cause significant damage to the condenser. To prevent this from happening, your A/C unit should be periodically flushed to remove them.
The Refrigerant Charge Is Too Low
If the lines of the refrigerant get cracks and holes, this typically results in A/C refrigerant leakage. If left unaddressed, the level will decline to a point where the compressor will have to work twice as hard just to pump sufficient refrigerant in order to cool the vehicle’s interior. Over time, this strain will cause it to malfunction prematurely. To avoid this, make sure your refrigerant lines are always in optimal condition and replace them if they aren’t.
Electrical failures are serious, since they lead to an acid buildup which can quickly wear out the compressor and other A/C parts. In the event that your compressor fails, the first thing you will want to do is have a technician perform an acid test. If they are found, this usually means electrical burnout has occurred and the system is so damaged that it will have to be replaced entirely. To prevent this, acid tests should be periodically performed to detect elevated levels as soon as possible.
The Coils Are Dirty
The condenser coil is a key part of any air conditioning system, but as time passes grime, mineral scales and dirt can accumulate on them. Once this occurs, the A/C won’t be able to efficiently expel heat, so it will be forced to operate continuously in an attempt to cool the vehicle’s cabin. The higher temperature and pressure in turn will make the compressor overheat and malfunction. To prevent this, clean your condenser coils regularly.
