Hot air is blowing from the condenser. Air conditioner blows warm air - problem solution

The main purpose of the air conditioner is to cool the air, but there are times when air conditioner blowing 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. Typically, warm air from an air conditioner is supplied 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 comfort temperature on the remote control.

2. The air conditioner requires refueling with freon

The second reason is that the compressor (condenser) of the air conditioner is not in good working order, or, which is more often the case, freon has "left" the system. Freon is the gas that is used to fill the air conditioning system. Through microcracks or in case of defects in the system, freon tends to evaporate and when the pressure of freon in the system drops, the air cannot cool to the desired temperature and, as a result, at the outlet air conditioner blows warm air... It is recommended to periodically, about once every 2-3 years, refuel the air conditioner with freon. This activity can be combined with cleaning the air conditioner and ordering service of the air conditioner.

3. Low voltage in the mains

The third reason is that the mains voltage is too low, which prevents the A / C compressor from starting. This usually applies to those houses where problems with electricity are traced at regular intervals. The problem may also lie in defects in the inter-unit wiring, which connects the outdoor and indoor units of the air conditioner.

4. Service required

The fourth reason may be the clogging of the heat exchanger and air filter in the indoor unit of the air conditioner. If you do not regularly clean the filters, then in just one and a half to two months, a layer of formed dust reduces the efficiency of the air conditioner by 2-2.5 times. As a result, the refrigerating capacity of the air conditioner is noticeably reduced, and freon is supplied to the compressor not in a gaseous state, as expected, but in a liquid state, which gradually leads to compressor breakdown.

It is better to entrust the solution of such problems to the specialists of the service center for the maintenance of air conditioners, who will qualitatively carry out the necessary diagnostics and eliminate the identified defects in the operation of the air conditioner, they will figure out why air conditioner blowing warm or stopped blowing the air conditioner.

Blowing from the air conditioner in winter

In winter, it happens that the air conditioner blows cold air. As you know, drainage from the indoor unit is discharged through a tube. If the drainage is diverted outside, it is quite possible that sometimes, in certain wind directions, you may feel that blowing from the air conditioner in winteralthough the air conditioner is off. This is not a malfunction.

The air conditioner blows weakly. Air conditioner blowing badly

There are situations that bad air conditioner... In this case, we can recommend that you service the air conditioner by contacting a specialized company. Most likely the filters are clogged and the air flow has decreased, so the air conditioner blows weakly or at all the air conditioner stopped blowing.

How to prevent the air conditioner from blowing?

How unpleasant it is for the owner of such a wonderful climatic technology as an air conditioner to find its breakdown! Especially if the air conditioner in the midst of summer not only stopped cooling the room, but began to blow warm or even hot air.

Unfortunately, this kind of malfunction is most often the result of improper air conditioning. You need it clean regularly from dust and dirt on your own, as well as invite a master for a deeper and more complete cleaning, preferably once a year.

Cleaning the air conditioner on time is not too time-consuming or expensive. But if this is not done, more complex and expensive repairs will be required.

Causes and types of breakdowns

The air conditioner blows warm air when the heat exchanger of the outdoor unit and the filters of the indoor unit are clogged with smoke, fluff, dirt, dust and other debris flying from the street and getting from the room. As a result, the air conditioning compressor overheatsand blowing warm. In the end, at one point, the compressor may jam.

Do not delay solving the problem of the air conditioner blowing with warm air, because the more difficult the repair, the more expensive it is.

Types of repair work in the case when the air conditioner blows with warm air:

• cleaning air conditioner,
• repairs compressor,
• replacement compressor.

To perform these works, order an air conditioner repair service from VseRemont24! An experienced and competent master will quickly and efficiently cope with any task.

In addition to the above problems, lead to breakdown of the air conditioner:

1. Problems with electricitylow voltage or defective outlet.
2. Failure control boards.
3. Disadvantage freon in system. This problem can also cause compressor failure. Until this happens, it is necessary to refuel the unit with freon. In addition, freon is a fairly toxic gas.

Unfortunately, quite often, even during incorrect or inaccurate installation of a new air conditioner, a breakdown occurs, leading to a gas leak. As a result, you may not have time to enjoy the coolness of the air conditioner, as you will have to repair it.

Undoubtedly, it is better not to wait until the problem of a lack of freon manifests itself in a particular malfunction, but to order service of charging the air conditioner with refrigerant at VseRemont24 approximately 1-3 times every three years.

As you can see, the problem that the air conditioner began to blow with warm air can only be solved by an experienced and qualified master. However, before contacting VseRemont24, check whether the force majeure was caused by ordinary inattention.

Is the air conditioner temperature set correctly? Is it worth the Heat mode? Also check all other parameters and settings. Re-read the instructions! Perhaps there you will find a solution to the problem if it lies on the surface and does not require special knowledge and skills. For example, it happens that because of the batteries sitting down in the control panel, you see some numbers and values \u200b\u200bon it, but in fact they are different.

In any case, you can rest assured. The VseRemont24 master who came to your home will find and quickly fix the malfunction of an air conditioner of any model and brand.

The exact cost of the repair is determined by the foreman after preliminary diagnostics.

For all types of work performed and installed components, you will be provided with a guarantee.

All climatic equipment is designed primarily to cool indoor air. But sometimes it does not work properly. Why does the air conditioner blow warm air in the apartment? Such a question can often be heard in the service center, where users contact after a malfunction. There are many reasons for the incorrect operation of a split system, but in this case there are no more than a dozen of them, which will be described in this article.

Before drawing conclusions and seeking help, it is recommended to independently analyze the performance of your split system. So, in addition to the equipment itself, the creation of coolness in the room is influenced by:

The period of operation of the air conditioner. Users often think that the air exchange in such devices is instantaneous and the coolness should come immediately after turning on the split system. But this is not the case. It takes 10 to 20 minutes to cool the room, depending on the performance of the device, the area of \u200b\u200bthe room and the outside temperature.

The ratio of the power of the air conditioner to external parameters. The air conditioner will blow warm air if its capacity is low. A low-power device, of course, will not be able to cool a spacious room, especially if it is hot outside. When choosing a device, buyers often take the device according to average external parameters, and lose sight of the fact that the load can be peak.

Isolation of the room. The split system will not cool enough the room if it has slightly open doors, windows or ventilation is on. This phenomenon is quite acceptable, since there is not sufficient forced air exchange created by the split system itself.

The appliance is blowing with heat due to the "blocked" inlet and outlet. Weak circulation and, accordingly, lack of coolness can be due to obstacles in the form of curtains, blinds or excess furniture.

If the performance of the air conditioner matches, the air passages are free, the doors and windows are closed, but anyway, the unit is blowing warm, then there is a failure in the equipment itself and it is necessary to diagnose it.

And you need to start by measuring the temperature at the inlet and outlet of the air conditioner. The initial temperature should be checked near the air intake grilles, and the final temperature should be checked in the air stream exiting the indoor unit.

Important! Do not check the degrees by installing the thermometer inside the device case, as it can break from the rotating fan impeller.

If, after measuring the indicators, the indicators do not correspond to the required values \u200b\u200bof 7-15 ° C, then there is some internal reason. Such a difference may be slightly different, depending on the manufacturer and brand of the air conditioner (you can check it in the passport of the device).

Why does the air conditioner blow warm air - frequent malfunctions

Sometimes it happens that the air conditioner blows with warm air, but some defects can be eliminated by yourself. The table below lists common flaws and how to fix them.

If the elimination of the listed problems did not help and the cooling situation did not improve, then most likely the problem is in the hardware device. And here a complete diagnostics is required, which can only be carried out by specialists in the service center.

Timely service is a guarantee of serviceability

When buying an air conditioner, many do not think seriously about carrying out regular maintenance of this equipment. Why hold it?

At first, this must be done in order for the split system to preserve its resource and to have to be repaired as rarely as possible.

Secondly, periodic maintenance of the equipment is necessary to preserve the power of the unit, since over time its losses are inevitable and as a result warm air will flow from the air conditioner.

Thirdly, if, due to poor inspection, the unit is out of order, then this will not be a warranty case and you will have to pay for repairs.

It is obvious that without systematic maintenance, the operating period decreases, and this is due to the fact that:

1. When the fans are running, dust is sucked into the air conditioner. And without regular cleaning of the split system, it will cover all the component parts of the air conditioner with a layer: a radiator, a heat exchanger, drainage taps and, first of all, air filters. When the condenser becomes dirty and, as a consequence, due to a decrease in the supply of refrigerant, the load on the compressor increases, which directly affects the service life of this unit.

2. Another important factor for regular maintenance is that warranty repairs exist only for factory defects or poor-quality installation of equipment. The consumer rights law clearly states that "defects caused by improper use of the product are not eligible for free repair." And the prevention of climatic equipment is a prerequisite for the operation of this equipment.

What should the specialists from the service center do when servicing? After all, it is common knowledge that the user is only allowed to clean or change the air filters.

Indoor module maintenance includes:

• Cleaning the heat exchanger.
• Cleaning the drainage system.
• Diagnostics and revision of electrical communications.
• Cleaning the fan.

The routine inspection and repair of the outdoor unit includes:

1. Cleaning the fan.
2. Topping up with refrigerant.
3. Cleansing the conditioner from dirt.
4. External inspection and control of electrical devices and connections.

In some service centers, HVAC equipment is serviced as scheduled twice a year: in spring before the onset of heat and in autumn after the end of the summer season. But even if they do not make detours, it is recommended that the user of the split-system himself call the specialists from the service department at least once a year. And then the climatic equipment will serve you for many years, maintaining comfort and coziness in the apartment.

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 has long been considered secondary. But today, leading manufacturers have changed their approach to this issue. It turned out that the heating mode can be very useful when the cold weather sets in, before the central heating is turned on. But sometimes situations arise when the system starts to malfunction. Why doesn't the air conditioner blow warm air? The reason may be incorrect operation or breakdown of one of the elements of the cooling structure.

Air heating

In order to find out why the air conditioner does not work correctly, 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 ceramic heating 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 operating principle when heating air. The coolant inside the structure changes the direction of circulation. Condenser and evaporative element change their roles. The air conditioner starts to cool the external air masses. In this case, warm air enters the room.

Cooling unit operation at low temperatures, possible consequences

If the air conditioner does not blow warm air, you should figure out whether it is capable of operating in this mode. Not all structures can heat the air in the room with the onset of winter frosts. Standard cooling systems operate in heating mode only up to a certain negative temperature. Typically this value should not exceed -5 ° C.

When using such devices at 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;
• operation 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 frost. It melts periodically. The water flows into the sump. Ice forms in it. This could 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, working conditions become more difficult. The air conditioner needs more energy to heat the air. When certain limits are reached, it can simply turn off and stop working.

Typically, the technical characteristics of the device indicate the temperature range in which its optimal functioning is possible. These parameters should be taken into account and the technique should not be used in an extreme mode.

Causes of system malfunction in heat transfer mode, solutions to the problem

The following reasons may arise for the poor-quality operation of the cooling device in heat transfer mode:

• ice plugs appeared in the connecting pipes. They impede the movement of the working substance. Defrosting is not possible during the winter period. You cannot 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;
• there is not enough freon in the air conditioner. This situation can arise in the event of a leakage and leakage of a gaseous substance. A wizard is invited to troubleshoot the problem. After finding problem areas, he seals them up and refills 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;
• breakage of certain parts of the structure may occur. Usually in this case, a malfunction code appears on the control panel. A service technician is called to restore the cooling unit.

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 warm? Don't panic right away. Such a mode of operation is associated with a change in the direction of movement of the coolant. This takes some time. Also, if there is a negative temperature outside, the compressor should pick up speed. You should be patient and wait.

Using inverter designs

As mentioned above, classic air conditioning devices are not well suited to operate in heating mode at low negative temperatures. Their efficiency decreases, heat losses increase. The risk of compressor breakdown increases.

Inverter models can be more efficiently used for heating a room, even with fairly severe frosts. There is a way to increase work efficiency. The external air stream mixes with the air in the room. In heating mode, it is necessary to compensate for the smaller temperature difference.

To improve the operation of air conditioners in winter, winter sets of equipment can be used. They consist of the following elements:

• devices for heating the drain system and external connecting pipes;
• Heating elements for fan and compressor;
• device for automatic adjustment of engine speed when temperature parameters change.

Installing the winter kit allows you to prevent damage to the outdoor unit when it is turned on in boundary conditions and prevents ice from forming in the drain pipe.

Should I use an air conditioner to heat the room?

The use of a cooling structure for space heating has several advantages:

• a sufficient amount of moisture remains in the air;
• no carbon dioxide is emitted;
• 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 aspects:

• 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;
• the risk of failure of the cooling device increases.

Heat transfer from air conditioning equipment turns out to be quite high and economically justified. Modern models are capable of operating at low negative temperatures. But they are just an addition to the main heating system.

When you turn on the air conditioner in your car, you expect to feel a breath of cool fresh air. However, this does not always happen. If there are some problems (major or minor), your car's air conditioner will not blow cold air.

Potential Causes of the Air Conditioner Blowing Warm Air

As already mentioned, the reasons for the lack of cold air can be different. Here are some of them:

• Lack of refrigerant. With a lack of refrigerant, the air conditioning system does not work (the clutch does not turn on, and the compressor does not work). In fact, this is the most common problem with no cold air supply. A lack of refrigerant in the system can be caused by a number of reasons, for example, leaks in the system circuit or malfunctioning of its components.
• A / C clutch switch malfunction. If the clutch switch is defective, the compressor solenoid valve will not operate. This means that no refrigerant is being charged and the system is not working.
• Damage or contamination of the radiator of the air conditioner. The radiator is where the magical transformation of the refrigerant takes place. If the radiator is dirty or damaged, then you will not be able to enjoy not only cold, but even slightly cool air.
• Plugging of highways. What happens if you pinch a garden hose? The water will not flow, will it? The same is true for the air conditioning system. If there is an obstruction in the system, it blocks the circulation of the refrigerant and the air conditioner does not blow cold air.

Although several possible causes of system malfunction have been described above, the most common is a lack of refrigerant. The amount of refrigerant in the air conditioning system naturally decreases over time, but this happens very slowly. However, the system may leak. If your car's air conditioner is not blowing cold air, you need to run system diagnostics. It should be carried out by a specialist certified to work with heating, ventilation and air conditioning systems.
