Many factors contribute to the poor performance of an air conditioner. Although some of the problems may be beyond your control, some issues are directly related to the lack of maintenance of the air conditioner.

Of the numerous people that contact us for air conditioning repair in Plano, TX, a faulty compressor is a common problem that leads to the poor performance of the cooling system. Given the constant need for repair in this regard, we have decided to address the issue by giving you tips to avoid a fault in the compressor.

There are equal likelihoods for you needing air conditioning repair in Plano, TX for reasons apart from a faulty compressor, but unlike some of the other problems, a fault in the compressor is avoidable if the owner stays diligent to the needs of the air conditioner.

Given the nature and the significance of a compressor in the air conditioning system, a breakdown in the compressor is bound to have a more profound impact on your wallet than some other common Air conditioning problems. There are also likelihoods of you replacing the whole unit due to a fault in the compressor.

Before we go about discussing the factors and their implications, it is imperative to understand the role of a compressor in an air conditioning.

Often called the heart of a system, the compressor is responsible for raising the temperature and pressure of the vapor refrigerant, leaving the evaporator coil. The compressor inhales low-pressure gas from indoors and after raising its temperature and pressure releases it as a hot, high-pressure gas.

The process is critical to the functioning of an air conditioner because it allows the air conditioner to benefit by transforming the refrigerant compound from gas to liquid. The liquid then condenses into a warm liquid which passes through high-pressure zones to become the fresh air that the A.C. releases.

Since the liquid refrigerant plays a critical role in the functioning of an Air conditioning, you can imagine how crucial it is to seek for air conditioning repair in Plano, TX if the compressor breaks down

Given our understanding of the compressor, the following reasons for fault in the compressor are within the control of the user. However, as a preemptive measure, it is crucial to understand that in case of a failure of the compressor replacing the compressor is not the only option. Until or unless you are not aware of the reason for the failure, there is no point in changing the compressor since the underlying cause will affect the performance of the new compressor too.

1.  Dirty Coils

The presence of dust, grime, and mineral scales on the condenser coil prevent the system from expelling heat. The accumulation of heat in the system eventually overheats the system and causes the compressor to overheat and fail.

The heat in the system accumulates and increases in intensity due to the prevalent pressure in the system, which eventually overheats the compressor.

2.  Low Refrigerant Charge

Holes or cracks in the refrigerant lines lead to the unit leaking crucial refrigerant. The leakage results in a sudden drop in the level of refrigerant in the unit and the constant drop mean that the compressor has to work overtime to pump enough refrigerant through the system.

The pressure and the strain the compressor has to go through to meet the needs and the requirements of the unit cause it to break down, resulting in you needing air conditioning repair in Plano, TX.

3.  Blockage in the Suction Lines

Unlike some of the other problems of the compressor, this is a slow and gradual process. The performance of the unit will give you an indication that you need air conditioning repair in Plano, TX. Ignoring the requirements and the need will eventually result in the compressor breaking down.

Dust and mineral scales can block or damage the air conditioners refrigerant lines, the first indication that the unit will give you of this blockage is by not cooling as effectively. If you do not fix the problem immediately, the accumulation of the dust will damage the compressor too.

4.  Suction Line Size

In case you need air conditioning repair in Plano, TX due to a leak in the refrigerant line, it is imperative to call for a skilled technician. An inexperienced person may develop a line that is too large or too small. This once again overburdens the compressor resulting in its premature failure.

5.  Refrigerant

A.C. types have assigned to them the refrigerant they need to function properly if you inadvertently add the wrong kind of refrigerant in your unit the outcome can be deadly for your compressor.

The same is the case with the quantity of refrigerant. Too little or too much refrigerant can also fail the compressor.

6.  Electrical Problems

The presence of acids is a signal that the fault in the compressor is due to an electrical failure. In cases like these asking for only air conditioning repair in Plano, TX is needless since the problem is not worth fixing.

If you call in a technician to deal with a problem in the compressor, it is imperative to ensure that the technician tests the presence of these acids in the system.
