Main Breakdowns of Split Systems

Split systems are becoming increasingly popular every year, as they enable you to maintain a comfortable temperature in rooms of various sizes and purposes effectively. Their affordable cost and advanced functionality make such air conditioners relevant in both summer heat and winter, as an additional source of heating.

Despite the reliability, any climate control equipment requires proper operation and regular maintenance. Without this, even the highest quality system can fail. In some cases, the problem can be solved independently, without special tools. However, in the event of more serious malfunctions, it is better not to take risks and utilize the professional AC repair in Fair Oaks from Alpha Mechanical to restore the device’s operation quickly and safely.

Diagnosing Faults in a Split System

Before you start repairing a split system, you need to roughly understand where to look for the fault. For this, there are error codes that are displayed on the display of modern equipment. If the climate control unit does not have a display, then the error may be indicated by the blinking of the indicator LED or sound signals.

Each manufacturer of equipment has its own codes indicating faults. To decipher them, you can use the technical documentation for the equipment. The decoding can also be found on the Internet by entering the model of the equipment.

Knowledge of error codes will help reduce the time it takes to find damage and try to handle the repair yourself. However, if we are discussing a serious fault, it is advisable to contact experienced specialists. 

The System Does Not Start

Most likely, in the case of this breakdown, there is damage to the electrical cable. If there is voltage in the network, but the compressor, fans, and indicator devices do not work, then you need to look for the problem in the following places:

• the network outlet;
• the cable and network plug;
• The power connectors on the control board.

Most often, the reason lies in a lack of voltage; however, sometimes, the voltage in the network is insufficient for the device to operate correctly. Most often, this happens due to an overload of the in-house network. This can be done with a multimeter. Additionally, the reason for the lack of power supply to the equipment may be due to dead batteries in the remote control, a malfunctioning remote control, or an inoperative power button on the equipment.

Water Dripping

Many owners of split systems face this unpleasant problem. Most often, it indicates a clogged drainage pipe.

There can be two types of blockage:

• mechanical (dirt gets clogged in the pipes);
• climatic (occurs in the cold season, when some sections of the pipeline can freeze, causing ice plugs to form).

Mechanical contamination is extremely rare. In this case, you will need to resort to manual cleaning of contamination, but you can use a compressor. Access to the drainage system pipes is carried out at the point of liquid drainage.

In the second case, you just need to melt the frozen sections of the drainage pipe. For this purpose, you can use industrial or soldering hair dryers, but in severe frosts, this procedure is not recommended.

If your split system is not just dripping but leaking into the room, contact specialists in air conditioner repair as soon as possible.

Unpleasant Odor

This indicates a clogged filter. When the air supplied by the indoor unit fan has an unpleasant odor, it means the beginning of bacterial proliferation on the surface of the contaminated filter. It must be changed immediately to prevent the occurrence of diseases.

However, replacing such a filter may not solve the problem of a foul odor. This is because contaminants may already be present in other parts of the indoor unit. Therefore, it is highly advisable to wash the main parts or order a comprehensive service.

Poor Cooling

There are several types of such a breakdown. Let’s consider a situation with poor cooling, to which dripping water is added. In this case, the main reason lies not so much in the clogging of the drainage system as in the clogging of the filters.

Dust does not settle on the filter cloth, but is layered on the surface of the evaporator. This prevents the release of cold, which is why the fan supplies insufficiently cooled air. In this case, water drips because the pipes freeze or dirt gets into the drainage. The first case is the most common.

To fix this malfunction yourself, you need to clean the filters. To prevent the canvas from deforming, you need to wash it under a stream of cold or warm water, but not hot. You can use special detergents or disinfectants.

Dust can be blown off the pipeline with a compressor or vacuum cleaner. Contamination can be removed more thoroughly if you completely disassemble the unit. But it is not recommended to do this without the proper skills.

In the case where poor cooling is accompanied by the compressor turning off, the reason lies in the contamination of the outdoor unit. If there is a lot of dust, and fluff outside the room, or there is a highway nearby, then the radiator and condenser will quickly become covered with a layer of dirt. This causes the compressor to overheat, which leads to its shutdown.

Warm Air Supply

If the split system does not cool, but on the contrary, supplies warm air, this indicates that the freon boils away before it gets to the evaporator. It boils away earlier due to clogging of the capillary tubes. A pressure difference occurs, as a result of which the refrigerant gives off cold to the fan, and the fan supplies warm air.

In this case, the compressor can work for a longer time or without switching off at all.

Conclusion

Split systems, if properly used and serviced in a timely manner, can last for many years without serious breakdowns. However, ignoring signs of a malfunction or trying to fix complex problems without the proper experience can lead to even greater costs. If your air conditioner has started to work unstably, extraneous noises have appeared, or it has stopped cooling altogether, you should not postpone repairs. A reliable solution is to contact Alpha Mechanical for professional air conditioner repair in Fair Oaks. The specialists of this company will help you restore comfort to your home and extend the service life of the equipment.
