Reasons: - Most likely, the filters of the indoor unit are clogged. Dust clogs the filters and settles on the heat exchanger plates. - Or there is not enough coolant. It is necessary to lift the front panel and remove the air filters. If there is not enough freon, the heat exchanger will not be cold, and its upper part will be covered with frost. It is necessary to fix the leak and add freon. - The temperature sensor on the indoor unit is broken, it must be replaced. - The radiator of the outdoor unit may be dirty. Dust and fluff have accumulated on the heat exchanger, preventing heat transfer.

- The outdoor unit fan is spinning slowly or is not moving; you need to clean the blades and lubricate or replace the fan motor. - There is a problem with the outdoor unit compressor. The table shows the work and spare parts that may be needed if the AC does not cool the air well. We will not only detect and fix the malfunction but also find out the reason for its occurrence. Our own warehouse of original spare parts and service center allow us to quickly and inexpensively carry out any repairs.

Failure of the temperature sensor on the indoor unit leads to the AC switching off before reaching the desired temperature in the room. Perhaps the problem is in the electrics or low voltage. Heavy contamination of the radiator of the outdoor unit due to accumulation of dust and fluff on the heat exchanger significantly worsens heat exchange, the split system blows with a barely cold stream, and after a while the compressor switches off due to overheating

Lack of lubrication, dirt or foreign objects that impede the rotation of the fan of the outdoor unit also interfere with heat dissipation and lead to overheating and shutdown of the compressor. Malfunctions of the compressor or related elements (control unit, sensors, etc.)

Reasons: The air ventilation mode may be on; you need to switch to cooling. - The air filters are very dirty, which is why the radiator does not give off cold, you need to clean them urgently. - If you lift the front panel and remove the air filters, and the heat exchanger underneath them feels like room temperature or only its upper part is cold and covered with frost, it is most likely due to a lack of freon. Usually, the leak occurs at the points where the copper tubes are connected to the external or internal unit, at the taps and at the joints of the pipes (where freon leaves the AC, oil leaks usually remain).

The radiator of the outdoor unit is dirty. This significantly worsens heat exchange and the compressor switches off due to overheating. It is necessary to wash the radiator with a high-pressure washer. The table shows the work and spare parts that may be needed if the AC blows warm air. We will not only detect and eliminate the malfunction, but also find out the reason for its occurrence.

Reasons: - First of all, it is worth checking and washing the filters that are located under the front panel of the indoor unit, as well as the plates of the indoor heat exchanger. Very often the cause can be dirt that clogs them. - Sometimes the fan drum becomes shaggy from dust balls and cannot blow air normally. - The heat exchanger of the outdoor unit can also become clogged.

The table shows the work and spare parts that may be needed if the air conditioner blows poorly. We will not only detect and eliminate the malfunction but also find out the reason for its occurrence.

Most often, the lack of air flow at the AC outlet is a symptom indicating a fan malfunction. It is necessary to remove the front panel of the AC to check the impeller and fan motor.

The table shows the work and spare parts that may be needed if the AC has stopped blowing. We will not only detect and eliminate the malfunction but also find out the reason for its occurrence.

If the blinds do not close completely, work with a limited amplitude or have stopped moving altogether, this indicates a motor malfunction. Most likely, it will need to be replaced. The table shows the work and spare parts that may be needed if the AC blinds have stopped working.

We will not only detect and eliminate the malfunction but also find out the reason for its occurrence.

This happens if the condensate collection tray is overflowing. There may be several reasons: - If the system operates at full capacity for a long time, the water does not have time to drain. - Freezing of the indoor unit heat exchanger leads to the formation of a large amount of water. The most common cause of freezing is a freon leak. - Clogged drainage system. If you do not regularly wash the filters, dirt begins to get into the heat exchanger and clog the drainage. Heavy dust particles settle to the bottom of the condensate collection tray and can form a blockage at the entrance to the drainage or get inside the hose.

- For air conditioners equipped with a drain pump, the cause may be its failure. - If a new AC starts leaking, most likely the drain hose is not laid at the proper slope, which makes it difficult for the produced condensate to exit to the street. The table shows the work and spare parts that may be needed if water drips from the AC into the room. We will not only detect and eliminate the malfunction, but also find out the reason for its occurrence.

- If the AC smells of stagnant moisture and mold when you turn it on, the source of this smell is most likely bacteria and mold fungi that appear in the mucous formations of the tray and dust growths on the heat exchanger and other internal surfaces of the AC. It is necessary to clean and disinfect. - Most often, it is enough to remove the front panel and wash the filters, heat exchanger and turbine, as well as clean and disinfect all parts of the drainage system.

- For air conditioners equipped with a drain pump, the cause may be its failure. - If a new AC starts leaking, most likely the drain hose is not laid at the proper slope, which makes it difficult for the produced condensate to exit to the street.

Reasons: - Indoor unit fan - Indoor unit transformer - Insufficient freon level - Drain pump - Outdoor unit fan - Compressor

Reasons: - If you hear a low hum or the indoor unit crackles when the AC is turned off, and only completely disconnecting it from the socket helps, most likely the transformer is the cause and it needs to be replaced. - In some cases, the transformer may be poorly secured in the housing. To eliminate its vibration, tighten the fasteners or put rubber pads under them.

If the indoor unit of the AC crackles, makes noise, hums or clicks immediately after installation, the most likely causes are: improper installation or poor quality of the AC. - If the AC makes noise when turned off, the reason is in the transformer. - When the AC is on, cracking and clicking sounds may be associated with the following problems: a foreign object, a crack in the fan blade, wear of the fan bearing, motor failure, loose housing or AC fasteners. - If hissing sounds appear when turning on the AC or starting the compressor, the cause is a problem with the refrigerant tubes: clogging, kinking, narrowing at the junction or soldering. - When the AC gurgles in the wind, air from the street is blown into the drainage system, this problem is easily eliminated. - If the gurgling sound appears in calm weather, most likely the drainage is clogged or there is not enough freon in the system. - If the AC has a drain pump, a cracking sound appears when it fails.

During normal operation, the outdoor unit hums smoothly and steadily. However, its operation may be disrupted due to: - Poor quality lubrication or its absence (moving parts will need to be disassembled and lubricated) - Imbalance of the blades due to dirt or mechanical damage, leading to imbalance of the internal structures and vibrations (cleaning, repair or replacement of the fan impeller is necessary) - Failure of the fan motor (resolved by repair or complete replacement)

Wear of moving parts or loosening of their fasteners (repair or replacement) - Compressor malfunctions, which are indicated by a crackling sound in the external unit (usually the compressor is repaired, in some cases it is replaced with a new one) The table shows the work and spare parts that may be needed if the external unit of the AC starts making noise. We will not only detect and eliminate the cause of the noise but also find out the reason for its appearance.
