What to do if the air conditioner does not blow warm air. Why is my car air conditioner not blowing cold air? Air conditioner blows warm air
Pressing the nipple will not do anything, since it will puff even at low pressure, in the sense that there are two sensors in the system along the contours of high and low pressure and if, along the low pressure circuit, the pressure will be less than the permissible one (I don’t remember exactly, but at the norm it should be like 4.6 - 5.5 kgf / cm2, but let the minimum limit wake up, for example, 4 kgf / cm2), then the sensor will not allow the clutch to turn on , as well as along the contour high pressure if, for example, your radiator is heavily clogged, then the freon pressure will increase and when a certain pressure is reached, the sensor turns off the clutch! I personally did this when I had the same problem, first I went to refuel (not from the officers) so that I could see the leak at night and whether the condo would work or not! If the clutch works, then electrical circuits kondeya everything is normal, look further, if cold air also blows out, then it’s generally fine (alas, I also forgot the approximate difference in air temperature at the outlet of the nozzle in the cabin and on the street, but ...

From the expanses of tyrnet: there is a leak in the system, but it was not immediately possible to find it (it is quite small), then you need to find it by crimping and eliminate it. To do this, blow gas into the system without turning on the air conditioner, since the gas pressure does not depend on whether there is liquid freon in the system or only gas. Therefore, it makes no sense to waste expensive freon by filling the air conditioner completely for pressure testing - then it will be released anyway to eliminate the leak. Having blown the system with gas to the stop, it is very useful to start the engine and warm up the car by turning on the stove, as with drying - this will increase the pressure of the gas in the system and make it easier to find a leak. Then (if you have a device) look for a leak using an electronic leak detector or the old-fashioned way - washing suspicious areas with soapy foam and watching for bubbles. Unfortunately, the "old-fashioned" method is still more reliable. The problem is that the leak detector, in addition to freon, also reacts to similar substances that are in a car ...

The first most banal, but easily solved reason for warm air from the air conditioner is that the switch is in the wrong position. This applies to reversible models that can work both for the production of cold and warm air. Make sure the switch is in the position you want. Or the temperature that was set on the remote control is higher than the temperature that was set in the room. The second already significant reason will be a compressor or condenser malfunction, or the most common cause malfunctions of the condenser - freon leaked out of the system. It is an inert, safe for humans gas that fills the air conditioning system. Periodically, once every 2-3 years, the air conditioning system must be topped up with freon, which gradually evaporates through microcracks or in case of system defects. With a drop in freon pressure in the system, there is nothing for the air to cool with - and as a result - at the outlet it will maintain its temperature. The third reason for not...

Here come the long-awaited cold weather!
And immediately there were questions about the fact that the air conditioner does not heat, heats poorly, blows cold, not warm, and so on.
I will try to answer most of them.
1) I turn on the air conditioner, for heat, but the fan does not turn on, it does not blow, when I turn it on in the cold everything is fine
This is a normal situation, the automatic air conditioner is programmed in such a way that until the temperature on the tubes of the indoor unit reaches a certain temperature (about 40 degrees C), the fan will not start working.
This time depends on:
Temperatures on the street, the degree of pollution of the air conditioner, how much the air conditioner is filled with freon (the lower it is from the norm, the longer) The warm-up time is an average of 3-5 minutes. Users of the air conditioner, as soon as they saw that the fan did not start, began to feverishly press the buttons on the remote control, switch to other modes, and so on.
You just need to turn on the heating mode and wait, if after 10 ...

The air conditioner does not heat - what to do?
0 votes, 0.00 avg. rating (0% score)
In autumn and spring, the topic is relevant: the air conditioner does not heat. Why is this happening and what to do?
1. There are no complaints about the cooling mode, however, the fan does not turn on in the heating mode.
The time to reach a certain temperature of the tubes of the indoor unit depends on the outside temperature, on how dirty the air conditioner is and is filled with freon. You need to wait from 3 to 5 minutes, and not immediately press all the buttons in a panic to deal with an imaginary malfunction. If after 10 min. heating has not started, then the problem really takes place.
2. The filter is dirty.
It protects the split system and our lungs from dust and unpleasant odors. It is advisable to take it out once a month and rinse it with warm water.
3. When the heating is turned on, the air conditioner does not react in any way or the indicator starts flashing.
The outdoor temperature must be within the allowable temperature range required for operation...

Why is the air conditioner blowing warm air?
The main purpose of an air conditioner is to cool the air, but there are times when the air conditioner blows hot air. There are several reasons why the air conditioner may blow warm or hot air.
1. Wrong operating mode selected
The first reason is the simplest. The air conditioner mode switch is in the wrong position. Normally, warm air from the air conditioner comes out in heating mode, which is indicated by the HEAT icon on the remote control. Switch the air conditioner to COOL mode. It happens that the temperature set on the remote control is too high in relation to the room temperature. In this case, set a lower comfortable temperature on the remote.
2. The air conditioner requires refueling with freon
The second reason is that the compressor (condenser) of the air conditioner is not working properly, or, more often, freon has “left” the system. Freon is the gas that fills the system...

The principle of operation of the air conditioner for heating
interaction of split system blocks
Most modern split systems can not only cool, but also heat. What is the principle of the air conditioner for heat, and is it different from the cooling process?
The basis of any refrigeration device operating on freon is the principle of phase transition of liquids at different pressures and temperatures, that is, the ability of freon to evaporate and condense under appropriate conditions.
When the phase transition temperature is below ambient, the refrigerant turns into vapor - it simply boils and takes heat from the air. If the phase transition temperature is higher than the temperature values of air, then freon is converted into a gas, at which it gives off heat back to the environment. Interaction with air goes through heat exchangers -...
The main causes of failure and repair options
The culprit for the fact that the air conditioner does not blow cold air can be ordinary pollution. After all, such equipment consists of two blocks. The purpose of the outer part is to cool freon, to drive air masses through the radiator grille. If it is clogged with dust and dirt, then the air does not pass. In this case, standard cleaning will help, which can be performed by specialists of any service organization.

In order to understand what a greenhouse is, you just need to get into the car on a hot day, after leaving it under direct sunbeams. Of course, this effect is familiar to every motorist. To solve the problem, some people buy a car with a light body, others apply tinting to the windows or use special devices to protect the interior from direct sunlight. But in fact it is difficult to call a real way out of the situation.
The only correct option is to install air conditioning or climate control in the car. Owners of cars with such equipment, as a rule, turn it on immediately after they get into the car. During the first seconds, the air conditioner blows warm air, but sometimes this time is delayed and you already understand that something is not working properly.
The disappointment can be quite serious. Of course, in such cases, you can go to the nearest service station and entrust the air conditioner repair to specialists. But...

Air conditioning devices are installed in order to create comfortable conditions in the room. Their main task is to cool the air. The heating function was considered secondary for a long time. But today, leading manufacturers have changed their approach to this issue. It turned out that the heating mode can be very useful when cold weather sets in, before turning on the central heating. But sometimes there are situations when the system starts to work incorrectly. Why is the air conditioner not blowing warm air? The reason may be an incorrect operating mode or a breakdown of one of the elements of the cooling structure.
Air heating
In order to find out why the air conditioner does not work properly, you should understand how it heats the air masses. After all, initially, the cooling mode was considered the main function. It turns out that the design of individual mobile systems includes heating ceramic elements. In this case, their operation is similar to that of a conventional heater. The disadvantage of such devices is the high consumption of electrical energy.
Modern models use a different principle of operation when heating air. The refrigerant inside the structure changes the direction of circulation. The condenser and evaporative element change their roles. The air conditioner starts to cool the outside air masses. At the same time, warm air enters the room.
Operation of the cooling device at low temperatures, possible consequences
If the air conditioner does not blow warm air, you should find out if it is capable of operating in this mode. Not all designs can heat the air in the room with the onset winter frosts. Standard cooling systems operate in heating mode only up to a certain negative temperature. Usually this value should not exceed -5 °C.
When using such devices in conditions of lower temperatures, the likelihood of problems increases significantly:
- the oil in the compressor becomes more viscous;
- the cooling substance changes its properties;
- dry start of the compressor can lead to its breakdown;
- work in extreme mode leads to rapid wear of parts and failure of the entire system.
An ice crust sometimes appears on the surface of the heat exchanger with the occurrence of frost. She melts periodically. Water flows into the tray. Ice forms in it. This may damage the fan. In addition, ice deforms the walls of the heat exchanger, leading to depressurization and leakage of the working substance.
Since heat enters the room from the external environment, when the temperature drops, the working conditions become more difficult. Air conditioner required large quantity energy to heat the air. When certain limits are reached, it can simply turn off and stop working.
Usually in technical specifications The device indicates the temperature range in which its optimal functioning is possible. These parameters should be taken into account and do not use the technique in extreme mode.
Causes of incorrect operation of the system in heat transfer mode, ways to solve the problem
The following reasons for the poor performance of the cooling device in the heat transfer mode may occur:
- ice plugs appeared in the connecting tubes. They impede the movement of the working substance. It is not possible to defrost during the winter period. You can not heat the main line. To solve the problem, switch modes of operation. This changes the direction of movement of the coolant. The external module heats up;
- the air conditioner does not have enough freon. This situation can occur in the event of a leak and leakage of a gaseous substance. Technicians are called in to fix the problem. After finding problem areas, he closes them and fills the system to the desired level;
- dirt appears on the surface of internal parts. It is necessary to periodically remove the decorative cover of the device and clean the main elements and filters;
- certain parts of the structure may break. Usually in this case, a fault code appears on the control panel. To restore the operation of the cooling device, a service wizard is called.
Sometimes immediately after turning on the device, it turns out that it does not work in heating mode. How to make the air conditioner blow heat? You don't have to panic right away. A similar mode of operation is associated with a change in the direction of movement of the coolant. This requires a certain amount of time. Also, if there is a negative temperature outside, the compressor must gain momentum. You have to be patient and wait.
The use of inverter designs
As mentioned above, classic air conditioning devices are not sufficiently adapted to operate in heating mode at low negative temperatures. They reduce efficiency, increase heat loss. The risk of compressor failure increases.
Inverter models can be used more efficiently for space heating even in fairly severe frosts. There is a way to increase the efficiency of work. The flow of external air masses mixes with the air in the room. In heating mode, a smaller temperature difference has to be compensated.
To improve the performance of air conditioners in winter period winter sets of equipment can be used. They consist of the following elements:
- a device that heats the drain system and external connecting pipes;
- Heating elements heating the fan and compressor;
- a device for automatically adjusting the engine speed when changing temperature parameters.
Installing a winter kit helps prevent damage to the outdoor unit when it is turned on in border conditions and prevents the formation of ice in the drain pipe.
Is it worth using an air conditioner to heat the room?
The use of a cooling structure for space heating has a number of advantages:
- enough moisture remains in the air;
- no carbon dioxide is released;
- heat output is greater than the amount of consumed electrical energy;
- microclimatic conditions in the room improve.
But along with the advantages, there are certain negative points:
- the service life of the air conditioner is significantly reduced;
- the oil thickens faster, its characteristics deteriorate;
- The efficiency of the device becomes less than the nominal value;
- increases the risk of failure of the cooling device.
The heat transfer of air conditioning equipment is quite high and economically justified. Modern models are able to work at low negative temperatures. But they are only an addition to the main heating system.
Although in modern models air conditioners and split systems provide for a heating mode, yet most users use equipment only in summer for cold. 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 external causes not related to hardware. 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. Additional influx of heat from outside or 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 freeze indoor unit conditioner. | (coarse 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 water. cold water and put the clean ones back in place. 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 the 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 the cooling is still weak or absent, then the problem is in the components and parts of the climate equipment. In this case, a full diagnosis by a specialist and service repair is required.
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 contamination of components 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. Besides, heavy pollution of the indoor unit may prevent the fan from rotating and cause the evaporator tubes to freeze. 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. |

| 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. Therefore, 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 difference 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 by the constant operation of the 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 particular difficult cases when it is not possible 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. AT high-rise buildings, with difficult access to the outdoor unit, you must 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). |

| 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.

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 outdoor unit), which is responsible for the thermal protection of the 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 briefly and turns off quickly when the room temperature is high 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. | It is necessary to replace defective sensors with 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. | A complete replacement of the fan or only its motor is required (if fan parts 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 a ventilation device and “drives” air without cooling. Communication often disappears in outdated models. Modern ones immediately signal an error code when the connection fails and will not work. |

Air conditioning in a car is an option that many take for granted. In the summer in the heat, it is indispensable for ensuring comfort in the cabin. However, regardless of the brand of the car, the quality and prestige of the brand, air conditioning systems fail from time to time. And this is where the question of repair arises. There are three main causes of failure: technological, external and operational.
Types of faults
Technological breakdowns depend primarily on the quality of materials and workmanship, and may include engineering errors. This kind of damage is almost impossible to influence, as this is a manufacturer's error. The main breakdowns include violation of the tightness of the system, jamming of the compressor, refrigerant leakage and many others.
External problems include exposure to an aggressive environment. The most common reason is pollution. To prevent damage of this kind, you must follow the rules of operation. Such problems are explained by the violation of the rules for the use and maintenance of the air conditioner, as well as its natural wear and tear.
Hot air from air conditioner
The most obvious sign of a problem that a driver can notice is warm air coming in instead of cool air. Most likely, the reasons may be the failure of the condenser, the failure of the fans or the lack of refrigerant. What to do if the car air conditioner blows warm air?
First you need to check the performance of the condenser, in the auto-conditioning system it is designed to cool the air. The condenser is located at the front of the machine, so over time, various foreign objects, for example, bags, candy wrappers and leaves. Just by inspecting this part of the car, and removing excess debris, it is often possible to restore the previous operation of the air conditioner.
Sometimes the capacitor is damaged by road gravel and other hard objects. In this case, most likely, it will need to be replaced. But, fortunately, it is easy to do it yourself and it is not necessary to go to a car service, since the capacitor is attached with several bolts in front of the car.
And the condenser needs to be flushed periodically. During operation, a lot of dust accumulates in it, which also subsequently worsens its performance. For service maintenance of the air conditioner, you can use the services of the company "Horizont". There, using special equipment, everything will be done quickly and efficiently.
The air conditioner does not cool the air
Another reason why the car air conditioner does not cool the air is the lack of refrigerant. To fix this problem, you need to check the amount of freon and, if necessary, fill it to the required level. With the constant operation of the air conditioner, approximately ten percent of the refrigerant leaks out in a year. Therefore, refueling the system should be regular. But first of all, you need to check if the system is tight and if there is a leak in it. If there is, it must be eliminated by replacing all hoses and fittings (tips) with new ones.
The air conditioner is idling
If, after checking the condenser and freon level, the car air conditioner works, but does not cool, most likely the fan is the problem. The auto-conditioning system works due to the uninterrupted blowing of the condenser. But, like any other part, over time, the fan fails. Faults can be detected by a simple visual inspection.
There are many problems, and not all of them can be diagnosed and fixed on your own. Therefore, experts recommend regularly undergoing preventive examinations in a specialized center, for example, in one such as Gorizont LLC. There, highly qualified personnel will check the level of freon and oil, carry out a complete cleaning of the system, including the condenser, and if a fan malfunction is detected, they will carry out a quality repair of the unit.
Air conditioning in your car working properly is an amazing thing. However, when it fails (which, of course, happens without fail on the hottest day of the year), it turns into a real mockery - warm, stale air begins to blow into the cabin. If your car's air conditioner is faulty, then you'd better not put off a visit to the service shop.
Automotive air conditioning systems have a rather complicated design, which predetermines the complexity of their repair without the necessary equipment and special knowledge. In addition, the refrigerant used in the system is subject to increased environmental requirements. We have identified the 3 most common air conditioning system malfunctions so that you have an idea of the reasons for its failure.
1.
The refrigerant leak itself is unique phenomenon, because when the pressure drops, it instantly turns into a gas. Closed air conditioning systems in cars are reliably sealed and do not require refueling. If there is not enough refrigerant in the system, it can be concluded that there is a leak that needs to be repaired.
Leaks from the air conditioning system do not lead to the formation of puddles under the bottom of the car, as happens with antifreeze. And only a professional mechanic is able to find almost imperceptible signs of leakage, such as oil deposits on pipe connections. Refrigerant leakage can also occur in the compressor, condenser and/or evaporator, that is, in almost all elements of the system. To detect them, as well as refueling, special equipment is used, including those using ultraviolet radiation, which allows you to diagnose and service your car with high quality.
2. Air conditioner compressor wear auto.
The compressor is the heart of the air conditioning system. Its function is to circulate the refrigerant to effectively remove heat from the passenger compartment. Like many other automotive parts, the A/C compressor wears out over time. Due to the complexity of the design, the compressor may fail if contaminants enter it or if other elements of the system break down.
How to prolong the life of your air conditioner compressor.
There are several ways to extend the life of an air conditioner compressor. First of all, at least once a month, turn on the compressor for about 10 minutes (even in the cold season), regardless of the ambient temperature. This is a very simple operation, since in most modern cars it is turned on together with the heater. Another way is the constant diagnosis of the air conditioning system, which should be carried out by professionals.
3. Air conditioning electrical system malfunction.
The air conditioning system includes many electrical wires, fuses, switches and pressure regulators, the coordinated work of which ensures safe and efficient work conditioner. In case of failure of any of these elements due to wear or defect, automatic shutdown of the entire system is provided for safety reasons. Without special equipment and, more importantly, the necessary knowledge and experience, diagnosing these problems is very difficult.
