Top 4 Preventable Causes Of AC Compressor Failure

Summer is coming and can be ruthless with its scorching heat. Therefore, ensure that your AC is working and check its parts, including the compressor.

Do you know how important your compressor is to your Air Conditioner? Your Air Conditioner is dependent on it. It is the heart of your AC unit and is responsible for its efficient running.

If you are having problems with your AC, there might be some issues with its compressor. Identifying those issues on time can help you avoid costly repairs. Calling a professional AC technician from Nor-Can Heating & Air for its inspection and maintenance can benefit you.

This blog will address the issues related to the preventable causes of compressor failure. We will also highlight the common symptoms of its failure. But before that, let’s see what the function of the AC compressor is.

What Is An AC Compressor?

An AC compressor is located in the outdoor unit of your HVAC system. The function of your AC compressor is to compress refrigerant and pump gas under pressure. The compressor squeezes the refrigerant, thus raising its pressure and temperature.

What Are The Common Symptoms Of AC Compressor Failure?

Let’s take a glance over the common symptoms of compressor failure:

  • Loud noises while running the compressor
  • Circuit breaker tripping
  • Ice on the cooking coils
  • Leaks around the AC unit
  • Blowing warm air into your room
  • Reduced airflow with higher electricity bills

If you experience any of these symptoms, it is wise to immediately call your HVAC contractor to have your AC checked.

What Are The Causes Of AC Compressor Failure?

The expected lifespan of an AC compressor is 10-15 years. However, your negligence can make it problematic earlier.

Finding the root cause of your air compressors failure can help you avoid worsening the situation. Find out the common causes of AC compressor failure here.

Dirt On The Coils

The purpose of the coils is to release the hot air outside. They regulate the temperature inside the room. However, coils can trap dirt, dust, and grime. This can hinder the expulsion of hot air from the coil. It also forces the unit to work harder.

Cleaning your AC evaporator coils using a mild detergent and a cleaner can last help them last a long time. Check your coils and keep them clean to ensure its lifespan.

Damaged Suction Lines

With time, suction lines can develop holes and cracks. This can reduce the cooling capacity of your system. Your AC won’t deliver the amount of cold air that you need. Your AC will run for longer periods and increase your electricity bills.

Low Refrigerant

A refrigerant is a chemical compound responsible for providing cool air to you and absorbing hot air from the environment. If there are places along your line that are leaking your refrigerant will leak out. The system can’t expel heat if the amount of refrigerant falls below a certain level.

Keeping the refrigerant at the required level will maintain your AC in a healthy condition.

Electrical Issues

Electrical issues are a major reason behind AC problems. If there is an electrical issue, it can lead to the accumulation of acids in your system. This can cause early corrosion not only to the compressor but to the other parts as well.

Inspect your wirings and ask your electrician to check everything just to be on the safe side thoroughly.

Other Causes Of AC Compressor Failure

  • In-adequate oil lubricant
  • Contaminants in the compressor
  • Incorrect suction line size
  • Old compressor
  • Too much refrigerant
