Why is the air conditioner not cooling well?

The main criterion good cooling air conditioner is the temperature at the outlet of the indoor unit, which should range from six to fourteen degrees, which depends on the degree of contamination of the system units, as well as on outdoor temperature air. At the same time, it is noted that the higher the air temperature outside, the lower the temperature distributed by the air conditioner should be. In addition, the outlet temperature directly depends on the manufacturer, dear japanese models have a temperature much lower than Chinese and Asian models. At the very beginning of their work, inverter air conditioners quite strongly cool the air in the room, after which they raise it to 15 - 18 degrees.

What are the main reasons poor cooling air conditioner?

1. Dirty indoor unit filters.

This problem is solved quite easily - just remove top cover front panel and carefully remove the air filters, which are a very fine mesh design. The cover is removed easily by pressing the plastic latches located on the sides of the panel. These filters should be washed in soapy warm water, then dried and put back in their place.

2. Dirty heat exchanger of one of the units.

During the flowering of poplar fluff, the radiator of the outdoor unit is very often contaminated, and with it the heat exchanger. Also, heavily polluted street air negatively affects the heat exchanger. It can be cleaned with a vacuum cleaner or a kershir - this is a sink that works under high pressure.

3. Strong contamination of the fan of the indoor unit.

You can remove it in the same way as in the case of air filters and rinse with soapy water or the same Kershir.

4. Insufficient amount of freon or its complete absence.

If this is the reason for poor cooling, then the system needs full charge or refueling with a special refrigerant - freon, which can be done by three different methods. But despite the chosen method of filling with freon, it is worth noting that only a professional should carry it out.

5. The fan of one of the units is out of order.

This unpleasant event can occur as a result of a breakdown of one of the additional boards or electric motor.

6. Four-way valve does not work.

This valve is used to switch from cooling to heating mode and vice versa. If it breaks, the valve must be repaired or replaced with a new one.

7. The compressor is out of service.

There can be several reasons for this phenomenon: it can simply jam, a breakdown of the case windings can occur, an interturn short circuit can occur, and so on. The compressor relay or capacitor may also fail. In the latter case, damaged parts can be replaced, and in the first case, you will have to change the entire compressor or even the entire indoor unit.

8. Temperature sensors do not work.

The reason may be open or closed sensors, and their resistance may also show incorrect values. As a result, the control board will not signal the system to turn on the compressor. If the sensors are defective, they should be replaced with new ones.

9. High or low pressure sensors do not work.

With this problem, the air conditioner simply will not work, so the burnt sensors must be replaced with new ones.

10. The capillary tube is clogged.

In order to eliminate this problem, the tube must be cleaned with a press or a new capillary tube must be soldered. If the tube is clogged with condensate, it can be purged using a vacuum process.

The most common causes of poor cooling of the air conditioner in the room have been presented to your attention. If the air conditioner is completely fixed, and the room is still hot and the air is humid, then you have chosen the wrong model and the system simply does not have enough power. In any case, before proceeding with the repair of the air conditioner, it is important to diagnose and identify the true cause of the malfunction. Why does the air conditioner not cool well?

The main purpose of an air conditioner is to cool the air so that people do not suffer from the heat on hot summer days. For a long time the heating function was considered optional and optional, but over time it turned out that it could be very useful, and many manufacturers began to build it into their products. Indeed, at a time when the cold has already set in, but the central heating has not yet turned on, it is the air conditioner with the heating function that can save the day. However, in some cases, the device may start to fail, in which case it is necessary to figure out what is the matter, whether the serious damage or some minor defect, which can be removed by hand.

How does the heating system work?

To understand why the air conditioner does not heat, you first need to figure out how it can perform such a function, if initially this device was intended only for cooling. Manufacturers of some mobile devices and split systems installed ordinary ceramic heating elements there or placed spiral devices in the system, then the device will work on the same principle as a conventional room heater. However, this option consumes a lot of electricity.

There is another method of heating, which is used in modern models. In this case, the direction normal traffic the refrigerant present inside changes, and therefore the evaporator and condenser, in fact, begin to change roles and perform each other's functions. Simply put, working in this way, the device still cools, only not the apartment, but the air on the street, and gives off heat to the room.

Safe modes for devices

Before you figure out why the air conditioner does not blow warm air, you should find out if it can perform such a function. Not all devices are able to warm the room in very coldy, and if the instructions do not contain additional instructions on this matter, then, most likely, the device can warm the air only at a certain temperature, up to -5 degrees Celsius outside the window. If you start using such an air conditioner in colder weather, you can provoke a number of changes that will lead to problems.

• Compressor oil may begin to thicken if the unit is turned on at low temperatures Oh. The properties of this substance change, as a result, the device can be started "on a dry start", which can lead to compressor failure. If you use the air conditioner in this mode for a long time, then important detail wear out quickly and stop working.
• Sometimes you may notice that the air conditioner, operating in heat transfer mode, suddenly stops heating. In this case, the equipment tries to correct the situation and may try to raise the temperature of the heat exchanger, which, if present, cold weather covered with ice. The water formed after melting drains, but does not completely go away, so frost may appear in the pan. This leads to failure of the compressor fan. In addition, ice can significantly damage and deform the heat exchanger, causing depressurization and leakage of refrigerant.
• If we take into account that the device takes heat from the street, then the lower the temperature, the more difficult it is for it to do this, and the more energy it consumes. As a result, the efficiency of work decreases and it may seem that the equipment does not heat at all if the difference between temperatures reaches about 3 degrees.

Usually, manufacturers provide data in catalogs and indicate the power for heating at a temperature outside the window of 7 degrees Celsius, so you need to take this fact into account when buying.

Do not torment equipment that is not designed for heating in real frosts. It is able to help when it is only slightly cold outside, but it is not suitable for severe cold weather.

Equipment with winter heating function

There are devices that can function properly even at low temperatures outside. Manufacturers produce such devices, so they can be purchased without any problems, and some craftsmen themselves install special components on a conventional air conditioner, filling it with R410A freon, which fully retains its properties even at low temperatures.

An inverter air conditioner can be used as a winter heater. These devices are quite expensive and are produced famous companies. Their specifications and features of the device ensure successful operation at a temperature of -25-30 degrees Celsius.

If the air conditioner does not work for heating, the reasons may be the following factors.

• The freon pipeline was clogged with an ice plug. If moisture gets into a sealed system for any reason, it can freeze and form a plug that prevents the refrigerant from moving through the system. It is impossible to defrost all this in the winter, heating the highways will also not help in such a situation. You can try switching modes to change the direction of the cooler, creating heat in the block from the outside. If this does not help, then you will have to wait for spring.
• If in the system an insufficient amount freon, it won't work. As a rule, this occurs due to depressurization and leakage. Usually in this case, the wizard is called to find trouble spot, carried out evacuation and refueling of the system.
• Contaminated parts can have a negative impact on the functioning of the device, preventing it from fully performing its functions. This problem will be solved by timely cleaning. The device should be cleaned periodically to prevent dirt from accumulating on the elements, as this also contributes to extending the overall life of the device. In addition, due to dirt, harmful bacteria can multiply, which negatively affects the health of people who are constantly indoors.
• Sometimes certain components fail, for this reason the operation of the air conditioner is disrupted. Modern devices equipped with a self-diagnosis system, so you can see the breakdown code on the panel. In this case, it is better to call a specialist who is engaged in the repair of equipment.

In some cases, even if the air conditioner does not heat up for some time after turning on, you should not immediately start to panic and think about breakdowns. First you need to wait, since turning on the heating mode involves some changes in the course of operation of the device, and this may take time while the system is rebuilt. If the street is too cold air, and the air conditioner has not yet gained momentum, it may also be cold in the room for some time, so you will need to wait a bit until everything returns to normal by itself.

Freon leak, or why your air conditioner does not cool?

In our everyday life, technology has already taken a strong place, because thanks to it, performing household duties and maintaining comfortable conditions is easy and effortless for a person. However, most agree with the fact that the equipment fails ahead of schedule. In particular, problems arise with climatic devices. The reason why the air conditioner does not cool can be various factors. This will analyze the most common of them, as well as give recommendations on what to do if the climate equipment is out of order.

Sources of malfunction of the split system air conditioner

If the air conditioner does not cool the air, then this is due to specific operating errors or natural processes that cannot be avoided, but which can be eliminated by simple methods:

• Clogged filters. Acting as an air purifier from dust and small particles, they are clogged with these elements, due to which the system may fail. You can clean the filters yourself without much difficulty: you need to open the air conditioner panel, remove the mesh and rinse it in cool water.
• Dirty heat exchangers. The air flows that pass through the heat exchangers carry particles of debris that settle on this part of the air conditioner. Cleaning the heat exchanger is quite difficult: you need to have some experience in working with the device and professional equipment. Therefore, most often this problem, which causes the air conditioner to work, but does not cool, or does not work at all, is eliminated by service specialists.
• The fan is clogged. This part of the device is located in the indoor unit of the air conditioner, therefore, in order to assess its condition, you will have to disassemble the air conditioner. This work is better handled by the masters from the service center.
• Clogging of the capillary tube with moisture. It can either be replaced or cleaned, for example by vacuum.

It is often possible to order a complete cleaning service for filters, heat exchangers and a fan at the same time, which will eliminate the main problems that cause the air conditioner not to cool.

• Leakage of freon (liquid, due to the heat exchange properties of which the air conditioner can perform its functions) or its insufficient amount in the system. In this case, regular refueling will be required. If there is a freon leak, the air conditioner may require serious diagnostics.
• Failure of one of the elements of the system responsible for the operation of the fans. These are parts of the air conditioner such as the control board, capacitor or electric motor. The reason may be mechanical influences to the system.
• Breakage of the valve responsible for the change temperature conditions- four-way valve. In this case, The air conditioner does not cool, but heats up continuously, or vice versa.
• Compressor malfunctions. This mechanism often jams, short circuits or breaks occur in its middle. Any malfunction of the compressor blocks the operation of the equipment, due to which the air conditioner does not cool or heat.
• Damage to pressure sensors or temperature sensors. Automatic system protection of the air conditioner will turn off the operation of the device until the elements are replaced with working ones.
• And the most banal reason that the air conditioner does not cool to the desired temperature is the wrong equipment. Each device has its own power and recommended area for which it can be used. If, for example, a low-power unit was purchased for a large room, then it will not be able to cope with the amount of air that is in the room and cool it well.

One of FAQ which the specialists of our company have to answer is the question: - “What is the reason that the air conditioner stopped cooling”? Another frequently asked question is:- "Why is warm air coming out of the air conditioner"?In this article, we will try to explain the main reasons why your air conditioner does not work properly.

In normal operating condition, modern non-inverter types of systems give an output temperature from the indoor unit on average from 6 to 14 ° C. Data temperature indicators vary depending on the degree of contamination of the outdoor and indoor unit. Most likely the outside needs to be cleaned. 1500 r. and domestic 2500 r. block. The cost of service already includes diagnostics 2000 r., refueling 2000 r., Total 8000 r. But it's better to order full service air conditioner 3500 r. The savings are obvious. The outdoor temperature and indoor temperature also affect the indicators of degrees. Everything is simply explained here - the higher the temperature outside and at home, the higher the degrees of the cooled air.

Experts know firsthand that the temperature of the air leaving the air conditioner also depends on the manufacturer. For example, European and Japanese brands that produce similar equipment show outlet temperatures slightly higher than models from Asian manufacturers. When buying a new inverter model of an air conditioner, you should remember that at the beginning of operation, the air cooling indicators are higher, but after the air in the room is cooled, these indicators rise to a value of 12-18 ° C. After spending small digression on the topic of the possibility of modern air conditioners, let's try to explain what is the reason for their poor performance.

Causes that reduce the performance of the air conditioner:

1. The indoor or outdoor unit of the heat exchanger is dirty. Most often, such problems arise during the flowering period of poplar, when its fluff strongly clogs the surface of the heat exchanger, forming a film. Traffic fumes are also a source of pollution for the external and internal heat exchanger. By ordering from our company service maintenance, you can be sure that the specialists will include the cleaning of the air conditioner in the list of work carried out. This can be done using Karcher under high pressure, as well as using a steam cleaner or using special chemicals by mechanical means;

2. The filters of the indoor unit are dirty. This problem is easily solved on their own to do this, it is enough to remove the cover of the indoor unit, which, as a rule, is fastened with plastic latches that can be easily pressed by the hand. Remove the filter and rinse it under running cool water and then put it back in place.

3. Block indoor fan is dirty. It is better to entrust this problem to specialists, since it involves disassembling the air conditioner. Fan cleaning is carried out under high jet pressure or with a regular brush.

4. There is not enough freon in the system or it is already completely absent. Revealing this problem, specialists fill the air conditioner with the required amount of refrigerant. First, they detect and eliminate the cause of its leakage.

5. Outdoor or indoor block fan does not work. There may be several reasons for this problem. The most frequent of them is the exit from the working state of the control board, electric motor, capacitor (working or starting).

6. Failure four-way valve. The directional valve located in the outside of the block regulates the changeover from warm to cold mode. If it cannot be repaired, then it is replaced with a new one.

7. Compressor out of order. There are several reasons for compressor failure. It can simply jam, which will lead to a breakdown of the starting or working mechanism, due to the breakdown of the windings on the case, there is a break inside it or a short circuit. In all these cases, you can do with the replacement of the thermostat and capacitor. In the rest, the replacement of the compressor or even the entire external unit is required. Compressors installed in inverter types of systems may start to work poorly due to the inverter power module.

8. Breakdown of temperature sensors. If the air conditioner does not turn on or the signal does not go to start the compressor, then this is a consequence of the opening or closing of the sensors. In this situation, their resistance level does not show a normal value. Arriving at the place of specialists replace the sensors with new ones.

9. Instrument failure pressure(high/low). The system, as in the cases mentioned above, turns on protection automatically, after which it is required to eliminate the malfunction.

10. Clogged capillary tube. If the capillary is clogged, then the equipment will never be able to function normally. You can fix this by cleaning or soldering a new tube. When the capillary tube is clogged with moisture, the moisture is removed by evacuation.

We have tried to list the most common causes unsatisfactory operation of the split system when it does not cool. If you notice that all the temperature indicators of the air conditioner are normal and at the exit it gives the required temperatures, but the room is not cool, then most likely you have chosen the wrong model that cannot cope with cooling a large area. You have no choice but to replace the air conditioner with a more powerful one or install another additional unit.

As in any other business related to identifying the causes of poor performance of equipment, it is very important to correct diagnosis, thus revealing the exact cause that led to bad job or broken air conditioner. It is very important for "diagnosing" to have special equipment at hand.

The specialists of our company have extensive experience and all the necessary equipment and special tools in order to arrive at the place, determine any malfunction, and then eliminate it by carrying out professional repair. Each owner of climate equipment must remember that even small deviations from the norm in the operation of the air conditioner require immediate identification of the cause. If this is delayed and hopes for “maybe it will work as before”, then there is a high probability that the air conditioner will completely fail. In this case, much more expenses, both financial and temporary, will be required in order to “revive” your climate equipment. The chances of encountering problems when the air conditioner does not cool well are much less for those owners who timely order such a service as “preventive inspection and Maintenance conditioners." The most common cause of poor air conditioning cooling is, as mentioned above, insufficient refrigerant in the system. The point is that even the most best models lose on average per year from 4 before 7% freon. This figure can increase many times if even small oversights occurred during the installation of the split system. Whatever the reason you are faced with, the specialists of our company are ready to quickly eliminate it and create comfortable living and working conditions for you. Offering the most affordable prices for services related to the repair and maintenance of air conditioners, our company Comfortable Climate Empire guarantees that after cooperating with us, your climate equipment will not let you down for a long time. So if the air conditioner is not working, call us and we will fix it.

Although modern models of air conditioners and split systems provide for a heating mode, most users still use equipment only in the cold in summer. Therefore, the equipment has a downtime period. But then the hot time began, you turned on the air conditioner after the winter and found that:

• split system does not cool, but blows warm air;
• the air conditioner started up, worked and stopped cooling, now the air conditioner blows heat, and the temperature in the room does not drop.

We have prepared an article about the reasons why the air conditioner blows, but does not cool the air, to help you understand the situation and decide whether to call the master.

Is the air conditioner really cold? We carry out diagnostics

Before looking for problems in the split system, check for external causes that are not related to the equipment. In addition to the cooling capacity of the air conditioner itself, the cooling of the room is affected by:

• Hours of operation of climate control equipment. Customers often forget that when an air conditioner is turned on, it does not instantly cool the air in the room. It takes 10, 15, 20 minutes to noticeably lower the temperature. Depending on the size of the room, the temperature outside and inside, and the power of the split system.
• Correspondence of the power of the split system with external parameters. A low-power air conditioner naturally cannot significantly cool a spacious room when it is hot outside and the room is very warm. When choosing equipment, it is often overlooked that the load can be peak, and the air conditioner must be taken with a margin of “strength”.
• Room isolation. The air conditioner in the apartment will not cool well if there are “holes in the tightness” of the room: open windows, doors, working ventilation system. An additional influx of heat from the outside or a forced outflow of cold air from the room are the reasons that lead to poor cooling.
• "Blocked" air inlet or outlet, another reason. Obstacles in the form of curtains, blinds, furniture interfere with normal air circulation and, as a result, cooling.

If there is enough power, the entrance and exit is free, the windows and doors are closed and enough time has passed, but it has not become cooler, then it is necessary to diagnose the equipment. Simply put, measure the air temperature at the inlet to the air conditioner and at the outlet.

The inlet temperature is measured at the air intake grilles. Put the thermometer on the body or hold it in your hand. The output is measured in the jet from the outside or by slightly pushing the thermometer inward through the blinds.

Attention! Do not push the thermometer deep into the case. It can get caught in the fan blades.

In a serviceable air conditioner, the temperature difference at the “input-output” is in the range of 7-15 degrees. If you just turned on the air conditioner for maximum cooling, and the difference is less than these values, then your split system does not cool well due to some internal reasons.

In addition, you can check the outlet temperature of the flow with the nameplate values. Usually, the equipment passport indicates the outlet cooling mode temperature, for example, 6-14 ° C for non-inverter systems. When turned on, inverters give the same parameters, and after reaching the set temperature in the room, they slightly raise the output value - up to 12-17 ° C degrees. If the temperature of the outlet stream exceeds the passport, then you should look for a problem inside the air conditioner.

The air conditioner blows warm air, what problems can be fixed by yourself

You can deal with some of the reasons for poor cooling yourself. The table summarizes the main ones, and gives recommendations for troubleshooting equipment failure.

sign	Possible reason	How to fix
The air conditioner does not cool the room well.	The temperature is set to high in the settings. For fast cooling, it is recommended to choose the minimum. And then switch to a comfortable one.	Adjust the cooling mode.
The air conditioner turns on but does not cool.	Fan mode selected. And the air just circulates without cooling.	Select cooling mode.
The air conditioner blows heat (for models with heating mode)	Heating mode on by mistake.	Set the cooling mode.
Cooling is weak. May leak and/or frost over the indoor unit of the air conditioner.	(rough and fine cleaning). Dust, wool, hair clog the filters and settle on the heat exchanger plates. Because of this, the heat removal from the evaporator worsens: the radiator does not release cold well into the air, which leads to poor cooling. If the indoor unit is very dirty, the evaporator tubes may freeze up. Dust can also clog the drain hose, causing condensate to remain in the sump and then drip from the indoor unit.	Clean filters. To get them, open the cover of the block. How to do this is described in the instructions. Then take out the filters and rinse well under running cold water and reinstall the clean ones. Attention! Use hot water not, the filters may be deformed. If you yourself are afraid to "climb" into the indoor unit of the air conditioner, call the master.
Poor cooling, the compressor in the outdoor unit stops.	The radiator of the outdoor unit is dirty. Dust, fluff from plants, plaque from the "exhaust" of vehicles have accumulated on the heat exchanger, the rotation of the fan may be difficult. All this impairs the heat exchange of the condenser with environment and reduces the cooling capacity of the air conditioner. In addition, the compressor may turn off due to overheating.	The outdoor unit needs to be cleaned. You can use a steam generator, pressure washer or mechanical means(brush, sponge). If the house is multi-storey, the services of an industrial climber may be required.
Blows warm air. The split system compressor located in the outdoor unit is silent or turns on for a short time (2-3 minutes) and turns off again.	Low voltage online. Lack of voltage often leads to overheating of the rotor winding and shutdown of the motor by a thermal relay.	Install a voltage monitoring relay. It can be placed separately or paired with a stabilizer.

If the elimination of these problems did not improve the situation and cooling is still weak or absent, then the problem is in the components and parts of the climate equipment. In this case, it is required complete diagnostics specialist and service repair.

The air conditioner in the apartment does not cool - reasons that require professional maintenance or repair

Symptoms of malfunctions are similar, but they occur due to wear or malfunction of parts, damage, internal pollution knots and mechanisms. Based on the experience of repairing air conditioners, the RemBytTech masters compiled a list of the main equipment breakdowns.

sign	Possible reason	Repair or replacement	Price* (only work)
The air conditioner blows weakly and does not cool well. Water may drip from the indoor unit and the evaporator tubes may freeze.	Clogged indoor unit filters(coarse and fine cleaning). Dust, wool, hair clog the filters and settle on the heat exchanger. The heat removal from the evaporator deteriorates, and the radiator does not transfer cold well to the air flow passing through it. In addition, severe contamination of the indoor unit may prevent the rotation of the fan and cause frosting of the evaporator tubes. When the drain hose is clogged, condensate remains in the sump and then flows out of the indoor unit.	The filters are cleaned after removal. When the evaporator and fan are dirty, the entire indoor unit is disassembled to clean the components.	from 1900 rub.
The air conditioner blows normally after winter, but does not cool well.	There is not enough freon in the air conditioner. Even in a sealed system, up to 7% of refrigerant per year can evaporate. That's why climate equipment requires annual maintenance (cleaning, refueling).	Freon is being recharged.	from 2300 rub.
There is airflow, but there is little or no cooling. At first, the compressor in the outdoor unit works without stopping, but the air conditioner, nevertheless, does not cool well. Then, the motor stops turning on, and the split system stops cooling. On models with an error indication, a low pressure message appears.	Freon has leaked from the system. At first, with a small amount of leakage, the air conditioning compressor located in the outdoor unit is less and less turned off for rest, despite poor cooling. Then, as the refrigerant evaporates from the system, the equipment begins to blow warm air at room temperature, and the motor stops and does not turn on. Typically, leakage occurs due to flaring of the joints of the interblock pipes or the destruction of the installation seams.	The technician is looking for a refrigerant leak. Then it seals the leak, evacuates the system (to remove moisture and air) and fills the system with freon.	from 3400 rub.
It blows normally, the compressor in the outdoor unit almost does not turn off, but the air conditioner does not cool at all or the cooling is weak. The air conditioner pipe up to the evaporator can also freeze up.	Clogged capillary piping. Due to a clogged capillary tube, the pressure drop at the inlet and outlet of the capillary increases, so part of the freon boils and gives off cold even before the air conditioner evaporator. As a result, the cooling capacity of the split system drops, and the equipment tries to compensate for its lack. permanent job compressor. When the pipeline is completely blocked, the refrigerant does not circulate, the compressor runs idle, the air remains warm.	Partial blockage is removed by blowing with air under pressure. This operation is also called pushing the blockage. To remove heavy blockage, hydraulic cleaning and solvents are used. In particularly difficult cases, when it is impossible to remove the blockage, the capillary tube is unsoldered and a new one is soldered.	from 3900 rub.
Split system blows but does not cool well. The compressor in the outdoor unit occasionally turns off.	The outdoor unit of the air conditioner is dirty. Dust, fluff from plants, plaque from the "exhaust" of vehicles have accumulated on the heat exchanger. In addition, the fan becomes dirty, and its rotation speed decreases. All these factors worsen the normal heat removal from the condenser, it does not give off excess heat to the outdoor air. Because of this, the quality of cooling of the split system is reduced. The air conditioner tries to compensate for the lack of cooling by the constant operation of the motor in the external unit.	The master washes and cleans the radiator. In multi-storey buildings, with difficult access to the outdoor unit, it is necessary to additionally order the service of industrial mountaineering.	from 2200 rub.
The air conditioner blows hot air when the cooling mode is on (in models with heating).	Faulty 4-way changeover valve. It is located in the outdoor unit and is responsible for changing the heating and cooling modes. In the event of a breakdown, the valve "jams" in heating mode.	The valve needs to be repaired or replaced. In some cases, if the heating mode is not needed, the valve is simply unsoldered, and the equipment always works for cooling. Usually this is done to reduce the cost of repairs or in the absence of spare parts (valve).	from 3500 rub.
Blows air at room temperature. The compressor is silent or turns off immediately after starting the air conditioner.	Compressor defective(in outdoor unit) . The main breakdowns are jamming, breakdown of the windings, inter-turn short circuit of the engine or open circuit.	The compressor needs to be replaced. In the case of a wedge, repair is sometimes possible (can be wedged). In some cases, it is more expedient to completely replace the external unit with a new one.	from 4200 rub.
	Faulty start and/or run capacitor(in the outdoor unit). The start capacitor is needed for the initial start of the compressor motor. Working - keeps the engine in working mode and increases efficiency. In case of loss of the nominal capacity of the capacitor, discharge, breakdown, the engine may not start or turn off shortly after starting.	The defective capacitor needs to be replaced with a new one.	from 1300 rub.
	Compressor thermostat failure(in the external unit), which is responsible for thermal protection motor. Because of this, the compressor is not supplied with power, and it does not start.	The thermostat needs to be replaced with a new one.	from 1500 rub.
Blows cold, but does not cool well. The split system turns on for a short time and quickly turns off when high temperature indoors and minimum temperature mode. cooling. Modern models give an error code.	Faulty temperature sensor or thermistor. He "monitors" the temperature in the room and is located in the indoor unit. In the event of a failure, it can “read” underestimated indicators, due to which the cooling is turned off ahead of time.	Replacement needed faulty sensors for new ones.	from 1400 rub.
	Faulty evaporator or condenser temperature sensors. According to their indicators, the pressure in the system is regulated for different cooling modes. If any of the sensors erroneously signals that the required cooling parameters have already been reached, then the air conditioner turns off ahead of time, without having cooled the room to the required temperature.
It blows, but the cooling is weak. The compressor in the outdoor unit can work without stopping and turn off by a thermal switch due to overheating.	The outdoor unit fan is defective. Most often, the engine burns due to dust ingress. This leads to poor heat removal from the condenser and poor cooling capacity, which the air conditioner tries to compensate for by the constant operation of the compressor. This leads to overheating of the motor, and its shutdown by a thermal relay.	Required complete replacement fan or only its motor (if spare parts for fans are sold separately).	from 1700 rub.
The air conditioner blows warm air when turned on.	Lost communication between blocks. As a result, the external one does not work. Without freon circulation, the indoor unit turns into ventilation device and "drives" the air without cooling. Communication often disappears in outdated models. Modern ones immediately signal an error code when the connection fails and will not work.	Restore power to the external unit (usually wiring, contact connections).	from 1500 rub.
	Faulty control board in the indoor unit. The cause may be jammed, punctured or burnt elements that start the compressor or fan of the outdoor unit. For example, power relays, amplifying circuits. In addition, the microprocessor may fail.	The control module needs to be repaired or replaced. The relay can be cleaned if the contacts are stuck. Damaged elements are soldered and replaced with new ones. At severe damage block, especially due to burnt microcircuits, the failure of the microprocessor requires a complete replacement of the control module.	from 1800 rub.
	Faulty inverter module(in the outdoor unit). It is present only in the inverter air conditioner and is responsible for powering the compressor. If the module fails, the compressor does not receive current.	The defective module must be replaced with a new one.	from 2300 rub.
