If your AC has started dripping water, there may be problems with the drain system, tray or fan blades. You should call a technician to perform the necessary repairs, including cleaning the tray and drain line, replacing or repairing the drain pump, cleaning the AC unit and checking the freon level. It may also be necessary to replace or repair the fan and check and clean the capillary tube.

If the AC emits an unpleasant odor, it may be caused by mold, dirty filters, antifreeze leakage, or the general ventilation system. To fix the problem, it is recommended to contact a technician who will clean and disinfect the indoor unit, replace the hose, and clean the filters. To prevent such situations, it is recommended to perform preventive diagnostics and clean the AC once a year.

The smell of plastic when turning on the AC is normal. However, the smell of burnt wiring requires immediate shutdown of the equipment, as this may indicate a serious problem, such as overheating of the wires or unit. Frequent causes of this smell are prolonged downtime, lack of maintenance or melting of wires. In this situation, it is necessary to call a specialist to conduct a full diagnosis and determine the problem. Repair may include cleaning or replacing system units, but this will be cheaper than a complete replacement of the equipment. It is important to note that ignoring this problem can lead to a short circuit and pose a safety hazard.

If frost or ice forms on the AC, this may indicate problems that reduce its performance. A common cause is dirty filters, so regular cleaning is recommended. A dirty evaporator may also be the cause, in which case professional cleaning is required. Another common cause is a refrigerant leak, which requires refilling and sealing the system. Regular diagnostics and preventive maintenance of the equipment are recommended to prevent icing.

Often these problems occur after several years of operation if regular maintenance is not carried out. Extraneous sounds in the indoor unit may be caused by contamination, problems with the fan, transformer, pipes, strong vibration or improper operation of the pump. In the outdoor unit, the cause may be the absence or wear of vibration-damping pads, contact of the mounting bolts with the reinforcement belt or the need to replace the compressor.

If the AC makes a crackling noise, you need to call a technician. The cause may be problems with the impeller, compressor, fan or drain pump. Malfunctions may be related to a lack of freon, a broken relay, overheating or a burnt-out compressor. If the crackling and clicking sounds are heard for a short time after switching off, this is normal.

A simple reason for this is contamination, which can be eliminated by carrying out preventive cleaning. However, sometimes the noise can indicate serious problems. The causes of noise from the indoor unit can be related to the wind that blows the air flow into the drainage system, or to mechanics, such as a fan or motor. Hissing of the indoor unit can be caused by various reasons, such as the wrong diameter of the tubes, a broken tube or a blockage. In some cases, the intervention of a specialist is required, such as replacing a worn sensor, eliminating poor contact or solving problems with the pump or wear of other working parts. If problems with the AC occur, it is recommended to contact a service center for maintenance.

The best way to eliminate excessive noise from the outdoor unit of the air conditioning system is proper installation and careful selection of parts, such as bolts and brackets. Often, noise is caused by worn gaskets, vibration of the housing or a rattling protective grille. The reasons may be unbalanced fan blades, a layer of ice or filling the fan with foreign objects. A technician will be able to eliminate all these problems by cleaning and checking the outdoor unit, as well as eliminating the cause of ice formation. If necessary, damaged fan blades will be repaired or replaced. If you cannot determine the cause of the noise yourself, it is better to contact a service center to avoid large expenses.

Unpleasant noise from the drain pump may be caused by clogging or breakdown. If the pump has not been used for a long time, it may start making noise due to lack of condensate. To fix the problem, you need to disassemble and clean the pump or replace it. You should also check and flush the drain tube. Regular maintenance will help prevent problems and avoid costly repairs.

Noise when turning on the AC can be a sign of serious problems. It can occur both during operation and when the equipment is idle. The main source of noise is the compressor. Sometimes the compressor can hum, but not pump freon. To avoid malfunctions, it is necessary to carry out timely maintenance, including cleaning and diagnostics. Low voltage in the network can be one of the reasons for the compressor humming. Contamination of the coil or clogged suction tubes can also cause noise and overheating of the compressor. Insufficient freon or lubricant levels can also cause problems. It is necessary to regularly check the freon level, since its absence can lead to compressor failure.

The AC works quietly, but the appearance of unusual sounds may indicate a problem with the circulation of the refrigerant. If the sound is whistling, the tubes may be clogged with dust or there is a freon leak. It is not recommended to solve this problem on your own. You need to conclude a contract for AC service for a professional solution.

The external unit of the AC can make noise for various reasons, such as contamination, problems with the fan, ice formation or a large temperature difference. It is necessary to regularly clean the unit from dust and debris, replace damaged parts and check the condition of the fasteners. If you cannot solve the problems yourself, it is better to seek help from specialists.

One of the reasons for the compressor humming is low voltage in the network. If the voltage is normal, but the compressor still hums and the housing is cold, then the reason may be different. Other reasons may be: contamination of the coil, clogged suction tubes, lack of freon and lubricant. It is necessary to regularly check the level of lubricant, since its absence can lead to overheating of the compressor and its expensive replacement.

It is important to follow the basic rules for long-term and reliable operation of the AC, such as correct selection and installation, correct operation and regular diagnostics and cleaning of the system. A delay in starting the AC can be caused by various reasons, such as incorrectly set temperature, broken thermistor, protection against voltage drops and others. If the AC takes a long time to start, there may be a problem with the liquid refrigerant or a malfunction of the control panel. To find out the cause and eliminate the breakdown, it is recommended to contact the service center and carry out periodic cleaning of all system units for long-term operation of the air conditioning equipment.

If the AC does not respond to commands from the remote control, the first thing you need to do is make sure that the equipment is working at all. Check for electricity and connection to the power source, and also try to turn on the system using the button on the body. Then check the operation of the remote control itself using a mobile phone camera. If the remote control does not give a signal, the batteries may need to be replaced. If the remote control works, but the AC does not respond, the problem may be in the photo receiver. This can be fixed by re-soldering or replacing the radio components. It is also possible that the wiring is broken, which needs to be repaired or replaced. The lack of response of the AC to commands from the remote control is not a dangerous breakdown, but it can cause inconvenience and discomfort. You can order such repairs from us.

Possible causes: no power, faulty socket, broken control board, broken wires in the connection, damaged remote control or signal receiving module, equipment in protection mode. First of all, you need to check the presence of electricity and the serviceability of the socket. If this is normal, check the voltage of the indoor or outdoor unit of the AC. If there is no voltage, replace the power cable. If the remote control works and the signal comes, the problem may be with the receiving board. If the AC turns off immediately or the protection is triggered, possible causes are compressor overheating or excess voltage. Try turning on the equipment later. If the problem is not solved, call a technician for repairs.

If the AC turns off immediately after starting or after some time, there may be different reasons. This may be due to incorrect operation of the temperature sensors or heat exchanger, a malfunction of the indoor unit fan, a burnt-out control board, or the need to replace the starting capacitor. There may also be problems associated with incorrect settings, compressor overheating, a breakdown of the outdoor unit cooling fan, unprofessional filling of the system, or a breakdown of the control board. In case of such problems, it is recommended to contact a technician or service center for diagnostics and repair.

If the external unit of the AC has failed, possible causes may include a jammed compressor, no power supply, or a missing winter kit. Sometimes the cause may be as simple as foreign objects or dust clogging. It is important to perform regular maintenance and follow the operating instructions to prevent such problems. If you turn on the AC at low temperatures, this may lead to freezing of the outlet pipe, heating of the compressor and formation of condensation, as well as freezing of the oil in the compressor. One of the serious problems is the failure of the compressor, which can be caused by the burnout of the motor winding, short circuit of the winding, or depressurization of the refrigeration casing. In case of depressurization of the casing, repair is required, and in other cases - replacement of the compressor.

If the AC does not create the desired coolness after switching on, this may be due to a problem with the external unit fan. Before starting repairs, check the power connection, program settings, and thermostat serviceability. If the fan starts working after spinning the blades, the blades may be unbalanced or damaged. If the fan does not work, the cause may be a motor shutdown, dirt or icing of the blades, lack of lubrication in the moving parts, oxidation of contacts, a malfunction of the controller or starting capacitor, or a breakdown of the motor. Work to correct the problem with the fan should be carried out in compliance with all safety precautions. It is recommended to contact professional technicians who can perform diagnostics and repairs, including cleaning or replacement of parts and modules.

If your AC does not turn on, you should check the functionality of the remote control, the voltage level in the network and the temperature outside. If all these factors are in order and the AC still does not work, you need to contact the service center. Possible problems may be related to insufficient refrigerant, compressor wear, automatic protection, open circuit or failure of the starting capacitor.
