Why Your AC Compressor Might Fail

Posted on

The compressor is one of the most critical components of your air conditioner (AC). In fact, some people call the compressor the heart of the AC since the AC cannot function with a compromised compressor. Knowing why the compressor might fail can help you prevent compressor problems. Here are some of the common causes of compressor malfunctions. Call an AC repair shop today if you experience any of the following. 

Blocked Refrigerant Lines

The compressor compresses the refrigerant and pumps it back into the house. Blocked refrigerant liens mean the compressor can't do its work properly. The compressor will keep trying to push the refrigerant even if the lines are blocked. This overworks the compressor, and an overworked machine overheats and breaks down more readily than one that operates within its tolerances.

Low Refrigerant

The compressor has to pump enough refrigerant to keep your house cool. The compressor will try doing this even if the refrigerant in the system is low, for example, if some of the refrigerant has leaked out. Again, the strain of overworking and trying to compress refrigerant that is not there can overheat the compressor to the point where it might overheat and break down.

Blocked Air Circulation

As you might have guessed by now, anything that forces the compressor to overwork can lead to its failure. One of these things is inadequate air circulation. An AC requires adequate air circulation for each circle of operations. For example, the vents and registers need to be free to allow air in and out of the rooms. The condenser and evaporator could need to be free from clogging to facilitate heat exchange.

Electrical Malfunction

At the heart of the compressor's operations lies an electrical motor. The electrical motor connected to a pump that drives compressed air back into the house. An electrical malfunction, such as damaged wiring, can affect the operations of the motor. The compressor won't be able to pump the refrigerant back into the house if the motor has malfunctioned.

Inadequate Lubrication

The compressor has both mechanical and electrical parts. The mechanical parts, which move, are lubricated to reduce friction and allow the compressor to function efficiently. This means contaminated or inadequate lubrication will increase friction, impair movements of the motor and pump, and affect the overall efficiency of the compressor.

As you can see, most of the problems associated with the compressor are things you can prevent. Maintain your AC and call for AC repairs as soon as malfunctions occur, and you will keep most of the problems at bay.
