Is your air conditioner colder than before, making strange noises or even dripping inside your home? Although many people think that these are inevitable failures due to the passage of time, the truth is that behind these symptoms there are usually specific faults hidden that, if detected in time, can avoid costly repairs and an increase in electrical consumption.
From refrigerant leaks to problems with the compressor or drainage system, there are very frequent incidents that affect the performance of this equipment. Knowing its causes and warning signs is key to acting before the problem gets worse. These are the most common faults in air conditioners and how to solve them.
If your air conditioner cools less and less, it could be losing refrigerant
Refrigerant leaks are one of the most common problems in air conditioning equipment. Contrary to what many people believe, this gas is not consumed with use. Therefore, if the system requires frequent recharging, it is most likely that there is a leak somewhere in the circuit.
Among the most common causes are component wear, corrosion of some parts, loose connections or incorrect refrigerant charging. When this occurs, the equipment loses its cooling capacity and must work for longer to reach the desired temperature, which translates into greater electrical consumption.
Some symptoms that may indicate a leak are lower cooling power, frost or ice forming on the evaporator, and longer than usual operation.
The solution is to locate the leak point, repair it and recharge the refrigerant following the manufacturer’s specifications. This is an intervention that must be carried out by a specialized technician, since it requires specific tools and the manipulation of refrigerant gases.
The most expensive air conditioning failure: signs that the compressor is about to break down
When it breaks down, the equipment may totally or partially lose its ability to cool the environment. Compressor problems can be due to different causes, such as lack of maintenance, electrical overloads, an inadequate refrigerant level, or natural wear and tear resulting from years of use.
Common signs of compressor failure include no cold air, unusual noises from the outdoor unit, irregular operating cycles, or difficulty starting the unit correctly.
To avoid costly breakdowns, it is advisable to carry out periodic checks and attend to any symptoms of malfunction from the first moment.
Does your air conditioner leak inside your home? These are usually the causes
One of the most frequent causes is the clogging of the drain pipe due to dirt, dust or residue accumulated over time. Leaks can also occur when the condensate tray is damaged or when the installation has an incorrect inclination that makes it difficult to evacuate the water.
The main symptoms are the appearance of drops or puddles near the indoor unit, humidity on walls or ceilings near the equipment and even bad odors derived from the accumulation of stagnant water. In addition to possible material damage, these incidents can encourage the appearance of mold and reduce the efficiency of the system.
The solution usually consists of cleaning the drain pipe, checking the condition of the condensate tray and checking that the installation maintains the appropriate inclination to facilitate the escape of water.
Little air and more heat: how to detect a broken fan before it gets worse
The most common breakdowns are usually related to the accumulation of dirt on the blades, motor wear, electrical problems or failures in some of the components that control its operation. These incidents can cause the fan to rotate with difficulty, operate at a lower speed than usual, or even stop working completely.
You can tell that the fan is not working well if you see insufficient air circulation, abnormal noises during the operation of the equipment, or a loss of ability to properly cool the rooms.
To solve this problem, it is advisable to periodically check and clean the blades and filters, as well as check the condition of the motor and electrical connections. If the origin of the fault is in the internal components of the fan, it will be necessary to call a specialized technician to carry out the corresponding repair or replacement.
If the air conditioning does not start or turns off by itself, check these electrical components
The capacitor is the component responsible for providing the energy necessary to start elements such as the compressor and fans. Over time it can deteriorate due to continued use, high temperatures or voltage fluctuations. On the other hand, the wiring can suffer damage due to wear, faulty connections or electrical installation problems.
When there is a fault of this type, it is common for the air conditioning to have difficulty starting, to turn off unexpectedly, or to make unusual noises when trying to start up. In some cases, it may even stop turning on altogether.
The solution is to inspect the electrical components to detect possible damage or faulty connections. Due to the risk involved in working with electrical installations, these repairs must be carried out by qualified personnel. Additionally, performing regular inspections can help detect problems before they cause more serious and costly breakdowns.
