What causes ac compression failure and how to fix it

An air conditioner is an integral part of comfort, especially in hot places like UAE. One of the most important internal parts inside your AC is the compressor. This compressor works like the heart of the mechanism in that it pumps refrigerant and keeps the whole cooling cycle running. When this has failed, your AC may entirely stop working. AC compression failures are quite serious issues that can occur for many reasons, including dirty filters, inadequate maintenance, blocked refrigerant lines, or problems in spare parts. When this happens, it becomes inconvenient as well as very costly if one does not attend to it on time.

If you understand the major components leading to failure of compressors, you can avoid large-scale breakdowns. Simple aspects such as clogged AC air filter, low refrigerant levels put a lot of pressure on the compressor as time goes on. Electric failure or usage of non-genuine AC spare parts adds on to the woes'. Most AC owners in the UAE resort to that trusted AC spare parts dealers in UAE to get the best parts for their systems. Hence, understanding the signs to check when it is leading to correct parts would save time and money. This article will highlight the primary causes of AC compressor failure and offer practical ways on how to solve them. 

Here are some of the causes of AC compression failure and how to fix it.

1. No Lubrication

Water lubrication along with oil is used for smooth functioning. In the case of an AC compressor, refrigerant oil is there in the system so that much friction is prevented which would cause premature wear down of compressor parts. By way of losing refrigerant, a leaking system also loses oil. Whereas, without lubricating oil supplementary supply to that compressor would be overheated and would break down.

How to Fix It:

A technician should check both refrigerant and oil levels. In the event of a leak, it must firstly be repaired. The system can then be refilled with the correct level of refrigerant and oil. If properly maintained, this won't happen.

2. Dirty Coils

Similarly, when the coils of the condenser are dirty and cannot emit heat, the system pressure increases, which leads to undue stress on the compressor. Increased pressure over time damages the compressor and decreases its longevity outlook.

How to Fix It:

Wash the condenser coils at least once or twice a year. You can do this using a coil cleaning spray or call for professional help. Keep the outdoor unit free from dust, leaves and debris.

3. Electrical Problems

It is mostly electrical faults such as defective wirings, power surge effects and blown fuses that make the compressor fail. Burned or corroded wires prevent power from reaching the compressor: or allow power, but will cause overheating.

How to Fix It:

A good electrician or HVAC technician should be able to inspect the electrical parts of the system. They can change out wiring, relays or capacitors that they find old and worn. A good idea is to install surge protectors to prevent electrical damage in future.

4. Foreign Bodies in the System

Dust, dirt, air, moisture, and acids can get into the AC system and contaminate the refrigerant. These alien elements will be responsible for damaging internal components of the compressor. In particular, moisture reacts with the refrigerant to form acids that are very harmful.

How to Fix It:

Once contaminants are found in the system, a technician may need to flush the system and replace filter drier and possibly, change compressor if it's damaged. The best way to avoid contamination is to seal the system tightly during repairs and use quality refrigerants.

5. Insufficient Refrigerant Levels

It is a fluid that removes heat from your home and then absorbs heat. If refrigerant levels are low, the compressor must work harder, which causes overheating and eventual failure of the compressor.

How to Fix:

Check for leaks in the refrigerant lines and repair them immediately. After the leaks are fixed, refill the refrigerant system with the right type and amount of refrigerant. This job should always be done by an HVAC technician.

6. Blocked Suction Lines

The suction line is the path through which refrigerant vapor returns to the compressor. If it is clogged or blocked, it restricts the flow of the refrigerant, which causes the compressor to low pressure and eventually gets overheated.

How to Fix It :

Examine the suction lines for blockages, dents, or leaks, and if necessary, replace or clean them. To avoid flow issues, always install the right size pipe and the right fittings.

7. Improper System Installation

Improper installations sometimes lead to compressor failure right from the start. System mis-setting, wrong pipe sizes, inadequate refrigerant charge, or mis-wired circuits can cause unnecessary stress in operation of the compressor.

How to Fix:

Engage professional services to inspect the installations. Any installation errors should be corrected immediately to avoid damage in the future. Always use certified HVAC technicians for installation.

8. Old and Worn-Out Over Time

Just like any other machine, compressors also get old after some time. The average lifetime span of most compressors is around 10-15 years. After that, some of the parts begin to be used up, making it prone to failure now and then.

How to Fix:

If the AC is quite old and the compressor fails, it is generally advisable to replace the whole unit rather than only the compressor. Newer units are also more energy-efficient and have better warranties.

9. Repairing a Failed Compressor

When your compressor has gone bad already, here are some suggestions about a fix: 

Replace the Compressor: This is usually the first option considered. In this option, the old compressor is removed and a new compressor of the same model is installed. 

Replace the Full Condenser Unit: If the AC is already old or if there are multiple parts that require repair, it would be cost-effective to replace the whole outdoor unit.

Upgrade the Full AC System: If both indoor and outdoor units are already old or mismatched, improving the entire system will upgrade performance and lower energy bills.

Use Warranty (if applicable): Is your unit or compressor still under warranty? Some compressors have a 5- to 10-year warranty. 

Last Tips to Avoid Compressor Failure

Schedule Maintenance for Your Air-Conditioning System: Yearly, the technician will inspect your system.

Keep Your Filters Clean: Harmful air filters reduce airflow and therefore cooling efficiency. 

Check Refrigerant Levels: Low refrigerants in air conditioning should be addressed now.

Install a Hard Start Kit: These are said to help old compressors start with less hassle on them.

Conclusion

AC compressor failure diagnosing the root cause is how to fix that problem. Changing a dirty AC air filter would restore proper airflow and alleviate pressure on the compressor. Refrigerant issue necessitates that a certified technician come and check for leaks and recharge the system accordingly. Sometimes electrical faults like damaged wiring or a faulty capacitor may be the cause. The use poor quality AC spare parts may also result in failure. So, it's always wise to purchase parts from trusted AC spare parts dealers in UAE to ensure performance and long-term reliability. 

Most certainly, take care of your AC by undertaking regular maintenance, cleaning its filters, and replacing parts that have worn out at the right time to avoid incidences of future problems. Investments on the best quality spare parts for the AC systems coupled with professionals will ensure that the efficiency of the cooling system is enjoyed for many years. Particularly in the high temperature of UAE, having the AC in an enviable condition is more than a luxury; it is a necessity. With the right knowledge and support from reliable dealers, AC compressor failure can be effectively managed in a manner that is quite affordable.
