The possible reasons for frequent air conditioning failures — complex mechanical components — are your air conditioner. Failure of one of them will damage the entire operation of the air conditioner, resulting in damage. For information , please visit our Singapore Aircon Service website.
When the weather is hot, you tend to use the air conditioner more often and use it with higher power. It is unfortunate that a faulty air conditioner cannot function at optimum capacity at this time. To avoid this, you must first understand the specific cause of air conditioning failure.
12 common causes of air conditioning failure
- Leakage of refrigerant
Refrigerant is a compound that can remove heat and moisture from the air in a room, leaving cold air behind. It is the blood of the air conditioning unit. Leakage of the cooling pipeline will result in low refrigerant content and low cooling efficiency.
Your air conditioner tends to balance and overwork, which can cause the entire system to collapse. Please note that unless there is a leak in the pipeline, the air conditioner will not lose refrigerant.
If you suspect that a refrigerant leak is a suspected problem with your air conditioner, please contact an HVAC technician. The technician will perform a leak test and repair the holes in the pipeline.
- Dirty filter
Filters are a key component of air conditioning and should be kept clean. Fortunately, you can perform this task yourself without calling a technician.
Dirty filters will impede normal airflow, thus reducing the efficiency of the system. Air passing through a dirty filter can carry dirt to the evaporator coil, which can also cause damage.
- Frozen or dirty evaporator coils
The evaporator coil contains refrigerant and is responsible for absorbing heat from the air. This coil needs hot air around it to function effectively. If ice or dirt covers its outer surface, they will not get the warm air they need.
Therefore, the evaporator cannot cool the air effectively. The cooling coil may be caused by the other problems mentioned above: coolant leaks and dirty filters. It is best to let your air conditioner undergo a professional inspection to understand the cause of the failure.
- Dirty condenser coil
Like an evaporator, the condenser coil must be free of dust or dirt. If your air conditioner is window -shaped, the condenser is located on the side facing outwards. For split air conditioners, the condenser is part of the outdoor unit.
Due to its location, the condenser coil tends to be exposed to dust and small debris. When it becomes too dirty, it may cause limited heat transfer. Your equipment may be redundant, and if not easily handled, spare parts will eventually wear out.
- Pipeline leaks
Piping system leaks are a common problem in split and multi-split air conditioners. If your air conditioner is not operating as expected, try checking its pipelines. These ducts bring cool air from the supply to your room.
There should be no holes or leaks that could cause cold air to leak to unexpected locations.
- Clogged drainage pipes
Drainage pipes help remove moisture released by the air conditioner from the air. Like filters, your equipment’s drainage system is also easily clogged.
In this case, the water will flow back or fill the disposal pot. Both of these conditions can cause potential hazards on other parts. Eventually, it can damage the entire system.
- Thermostat problem
The thermostat is the control center of the air conditioning unit. It reads and displays the temperature of the indoor air conditioner and helps you change the temperature setting. You must check the thermostat calibration, especially if you have an old dial style.
Properly calibrated thermostats can be the cause of problems because they are unable to obtain the correct order from the controller. Also check the battery and replace it when it no longer works properly.
- Fan failure
The air conditioning system has two fans; each has a different purpose. The first evaporator coil to blow warm indoor air through the cooling air. Another fan blows air through a condenser, releasing the heat absorbed to the outside.
If this fan does not work properly, it will cause poor airflow. This can happen due to a faulty fan motor, excessive dust, or belt and lubrication problems. If a faulty fan or component is not repaired or replaced, the air conditioning compressor may be threatened.
- Electrical problems
Possible Causes of Frequent Air Conditioning Damage
Electrical problems in air conditioners include bad capacitors, burning contractors, and improper wiring. Capacitors and contractors are responsible for running the compressor and fan motors. A weak capacitor cannot transmit enough vibration to keep the motor running.
The burning contractor was unable to provide sufficient voltage to start the motor. Improper wiring will naturally impede current flow. In both of these cases, the system will not operate normally or at all.
- Old unit
The air conditioner may also not work because it has been in operation for a long time. With a cycle of wear and repair, your air conditioner will reduce its original efficiency. The hottest seasons will challenge air conditioning, and your old machine may not be able to handle it easily.
- Improper maintenance
In addition to damage to certain components, frequent air conditioning failures may also be due to improper maintenance. Some maintenance tasks can be done yourself. This includes cleaning the outer surfaces of filters and equipment.
For more complicated procedures, please contact a professional air conditioning repair service. You can ask them to support customization services, including inspection of refrigerant, coils, pipes and other mechanical parts. They also provide maintenance services.
In addition to a regular air conditioning maintenance plan, you should also provide adequate rest periods to the air conditioner. Long -term high operating power can cause overheating, mechanical and electrical problems, or worse, compressor failure.
Reduce the load on the unit. Use other methods to keep you cool in the summer. It will save your AC power from damage and save your pocket from extra electricity bills.
Possible Causes of Frequent Air Conditioning Damage – Conclusion
Mechanical systems such as air conditioning give people comfort and convenience in performing tasks. Proper maintenance and management will allow the system to function effectively for a longer period of time. With this, you can save money and energy while getting adequate output.
