What are the common causes of air conditioning failures? To find out, read on!

3 of the Most Common Air Conditioning Breakdown Causes

Is your air conditioning making a strange noise? One of your indoor units no longer blows cold air? In the event of an air conditioning failure, a few good reflexes allow you to detect the source of the problem and solve it, alone or with the help of a pro.

Air Conditioning Failure: Signs To Look For

Several anomalies can cause air conditioning problems in the house. To know if you are experiencing an air conditioning failure, look to identify the following signs:

  • Unusual noise
  • Jerky operation
  • Unexpected shutdowns of one or more units
  • Bad smells
  • Dripping or leaking liquid (s) on the outer unit
  • Lights off or flashing
  • Blown fuses
  • Remote control malfunctioning: the device no longer responds!

These different signs of an air conditioning failure can be isolated, or on the contrary, combined. Some are indicative of a small problem that is easy to contain, such as a clogged filter. On the other hand, others may indicate a more serious problem, requiring the intervention of an air conditioning specialist. If the expert declares that a repair is not possible, then it’s best to look for a reputable store in your area where people buy air conditioners.

Let’s go through some of the most common air conditioning breakdown causes that lead to the above issues!

3 Common Causes of Air Conditioning Failures

1. Problems Related to Filters

When your air conditioner’s indoor unit stops blowing enough air (cold or hot), it is often caused by the clogging of the filters. The same is the case if your device makes an unusual noise, stops for a few moments, or works jerkily. In this case, depending on the condition of the filter, you must either clean it or replace it.

The clogging of the filters is an air conditioning failure that is easy to repair. Here’s how to clean your unit’s filters yourself:

  • Switch off the device completely
  • Open the unit and carry out a first dusting of the filters with a vacuum cleaner
  • Then take out each filter and clean it with a sponge, soaked in soapy water or a little washing-up liquid.
  • Rinse the filter for a long time with clean water and dry it completely before replacing it.
  • Do you have multi-split air conditioning? Repeat the procedure on each of the indoor units.

However, the operation can be tricky, for example, if there is too much or not enough oil to operate the cogs of the device, or if some parts are too worn or damaged and require a new installation inside the device. In these cases, the intervention of a professional can be both quick and beneficial. They will put the right parts in the right place and check the general condition of the machine. Normally, cleaning or replacing an air conditioner filter is done once or twice a year.

Remember: Cleaning with water is only possible if your filters are made of plastic. If they are made of another material, just use a vacuum cleaner.

2. Leakage Problems

A leakage problem in an air conditioner is more insidious, but once detected, it invites you to react quickly so that the water does not damage your home. Normally, natural condensation from the air conditioner evaporator drains into a condensate pan, then is continuously discharged through the drain pipe. But if the leakage is all over the place, it is an alarming sign. The first thing you must do immediately is unplug your air conditioner. Then you have to identify the cause of the leak.

Start by checking that this runoff is not due to a full condensate tray or even simply to an air conditioner that is too inclined. The sump pump may also be worn or broken. The air conditioner exhaust pipe may also be blocked with dirt or damaged. Waterproof tape can repair a deteriorated pipe, but all other cleaning or part replacement should be done with care. It is better if you leave it to a professional so as not to aggravate the problems. To prevent this from happening, the best way is to drain them periodically. 

3. Overheating

Overheating of the motor will make your air conditioner work less and make an unusual noise. You have to unplug the air conditioner and let it rest, and cool down. Allowing the engine to rest will eliminate noise and make the machine want to run most of the time smoothly.

However, if the problem happens too frequently or persists even after the engine rest, it is better to seek professional help. Experts trained in air conditioning, such as the Sun City Air team, specialize in detecting and fixing air conditioning problems. In addition, the intervention of professionals guarantees the right solution preventing further damage to your device.

Maintain Your Air Conditioning Properly to Avoid Breakdowns

Depending on the model of your device, the frequency of maintenance – and checks – may vary. Your air conditioning manual usually tells you when:

  • Clean your filters
  • Call a professional for verification.

It is recommended to unclog the filters approximately once a month, regardless of the type of air conditioning (mono or multi-split). However, regardless of the cause or the issue, a regular inspection visit is essential. It guarantees the correct operation of your air conditioner to prevent these common causes leading to its failure. 

When to Call a Professional?

Air conditioners are generally good quality and sturdy devices. For them to accompany you for a long time, it is better, in general, not to risk too much to try to repair the operational problems yourself. These concerns are generally few, so the occasional intervention of a professional technician will save you some hassle while preserving your schedule.

It is useful for small parts changes, smart to discover the precise origin of a functional problem, and obligatory for the repairs that could put you in danger. For example, an important runoff from the device or a leakage in the refrigerant is highly harmful where a professional’s intervention is essential. Everything is repairable and can give your device many more years of good functioning, but you still have to call the right person!

We hope this information has answered many questions and concerns about the causes of air conditioning failures and their solution. Your air conditioners are essential for comfort in any season and therefore need care. Some issues can be identified and fixed easily. In some cases, professional help becomes compulsory. Whatever the cause and the solution you opt for, setting your device back in good working order, you have to be attentive.
