Hot air is blowing from the air conditioner. The air conditioner blows warm air - a solution to the problem

The main purpose of an air conditioner is to cool the air, but there are times when 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 comfort temperature on the controller.

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 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 1 time in 2-3 years, refuel the air conditioner with freon. This event can be combined with air conditioning cleaning and order air conditioning service.

3. Low voltage in the mains

The third reason is that the mains voltage is too low, which does not allow the air conditioning compressor to start. This usually applies to those houses where problems with electricity are traced with a certain frequency. The problem may also lie in defects in the inter-unit wiring that connects the outdoor and indoor units of the air conditioner.

4. Service required

The fourth reason may be the contamination 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 the layer of dust that forms reduces the efficiency of the air conditioner by 2-2.5 times. As a result, the cooling capacity of the air conditioner is noticeably reduced, and freon enters the compressor not in a gaseous state, as expected, but already in a liquid state, which gradually leads to a breakdown of the compressor.

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

Air conditioner blowing in winter

In winter, the air conditioner blows cold air. As you know, the drain from the indoor unit is drained through the tube. If the drainage is taken outside, then it is quite possible that sometimes, with certain wind directions, you may feel that blowing air conditioner in winter even though the air conditioner is off. This is not a malfunction.

The air conditioner blows weakly. Air conditioner blowing bad

There are situations that air conditioner blowing bad. 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 air conditioner stopped blowing.

How to make sure that the air conditioner does not blow?

How unpleasant it is for the owner of such a wonderful climate technology as an air conditioner to discover its breakdown! Especially if the air conditioner at the very height 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 maintenance of the air conditioner. Need it clean regularly from dust and dirt on their own, as well as invite the master to carry out a deeper and more complete cleaning, preferably once a year.

Timely cleaning of the air conditioner is not too costly either in time or in money. 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 fumes, fluff, dirt, dust and other debris flying from the street and falling from the room. As a result, the air conditioner compressor overheats and blowing warm. Eventually, at some point, the compressor may jam.

Do not delay the solution of the problem of the air conditioner blowing 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 warm air:

  • cleaning conditioner,
  • repair 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, The breakdown of the air conditioner is caused by:

  1. Problems with electricity, namely low voltage in the mains or a faulty outlet.
  2. Failure control boards.
  3. Flaw freon in system. This problem can also cause the compressor to fail. Until this happens, it is necessary to refuel the unit with freon. In addition, freon is a rather toxic gas.

Unfortunately, often even during incorrect or careless installation of a brand 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 have to repair it.

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

As you can see, the problem that the air conditioner began to blow 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 temperature on the air conditioner set correctly? Is it worth the heating mode (Heat)? Also check all other options and settings. Reread 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 that are sitting in the remote control, you see some numbers and values ​​​​on it, but in fact they are different.

In any case, you can be calm. The VseRemont24 master who came to your house will find and quickly fix the problem of an air conditioner of any model and brand.

The exact cost of repairs is determined by the master after a preliminary diagnosis.

For all types of work performed and installed components you will be given a guarantee.

Any climatic equipment is created, first of all, for cooling of air indoors. But sometimes she fails. Why is the air conditioner blowing warm air in the apartment? Such a question can often be heard in a service center where users contact after a malfunction has occurred. There are many reasons for the incorrect operation of the split system, but in this case there are no more than a dozen of them, which will be discussed in this article.

Before drawing conclusions and seeking help, it is recommended that you 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 of such devices is instantaneous and coolness should come immediately after turning on the split system. But it's not. It takes from 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 air conditioner power to external parameters. The air conditioner will blow warm air if it has a low capacity. A device of low power, 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.

Room insulation. A split system will not cool the room enough if doors, windows are ajar, or ventilation is turned on. This phenomenon is quite acceptable, since there is no sufficient forced air exchange created by the split system itself.

The appliance blows heat due to a “blocked” inlet and outlet. Poor circulation and, consequently, lack of coolness may be due to obstructions in the form of curtains, blinds or excess furniture.

If the performance of the air conditioner corresponds, the air passages are free, the doors and windows are closed, but still, the unit blows heat, then there is a malfunction in the equipment itself and it is necessary to diagnose it.

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

Important! You can 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\u200bin 7-15 ° C, then it means that the reason is some kind of internal. Such a difference may be slightly different, depending on the manufacturer and brand of the air conditioner (you can check in the device passport).

Why does the air conditioner blow warm air - common malfunctions

Sometimes it happens that the air conditioner blows warm air, but some defects can be fixed on your own. The table below lists common flaws and how to fix them.

Symptom Possible malfunction Solutions
The air conditioner blows heat (on appliances with heating settings) Wrong mode set Set the desired function
No coolness, cooling is weak The filters of the internal module are clogged with debris Clean or replace filter elements

Important! Do not use hot water when cleaning, as it can deform the filters.

Split system does not cool well High temperature set during settings Turn on the minimum, and then switch to a comfortable temperature
The air conditioner works but does not cool Fan mode enabled Adjust the correct mode
Weak blowing from the air conditioner, while the compressor turns off Clogged external radiator. A layer of dirt has formed on the heat exchanger, which reduces the cooling capacity of the air conditioner. Clean out the radiator
The air conditioner blows hot air. Compressor turns on for a short time Low mains voltage. Insufficient voltage often causes the rotor to overheat and shutdown the motor due to protection. It is recommended to turn on the device only through a voltage stabilizer

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 design. And here a complete diagnosis is needed, which can only be carried out by specialists in a service center.

Timely service - a guarantee of serviceability

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

First of all, this must be done in order for the split system to maintain its resource and have to be repaired as rarely as possible.

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

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

Obviously, without systematic maintenance, the operating period is reduced, 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 with a layer all the components of the air conditioner: radiator, heat exchanger, drainage outlets and, first of all, air filters. When the condenser is contaminated and, as a result, due to a decrease in the refrigerant supply, 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 law on consumer rights clearly states that "defects caused by improper use of the goods are not subject to free repair." And the prevention of climate equipment is a necessary condition for the operation of this equipment.

What should the specialists from the service center do during maintenance? After all, it is well known that the user is only allowed to clean or change air filters.

Maintenance of the indoor module includes:

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

Preventive inspection and repair of the outdoor unit includes:

  1. Fan cleaning.
  2. Refilling with refrigerant.
  3. Air conditioner cleaning.
  4. External inspection and control of electrical devices and connections.

In some service centers, maintenance of climate equipment is 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 rounds, it is recommended that the user of the split system call 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 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 for what reason 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 of 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. The air conditioner needs more energy to heat the air. When certain limits are reached, it can simply turn off and stop working.

Usually, 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 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, classical 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 operation of air conditioners in winter, 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.

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. With some problems (serious and not so) your car air conditioner will not blow cold air.

Potential Causes of an 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. If there is 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 cold air supply problem. The lack of refrigerant in the system can be caused by a number of reasons, such as the presence of leaks in the system circuit or the failure of its components.
  • A/C clutch switch failure. If the clutch switch is faulty, the compressor solenoid valve will not operate. This means that there is no refrigerant charge and the system is not working.
  • Damaged or dirty air conditioner radiator. 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.
  • Highway blockage. What happens if you pinch a garden hose? Water won't flow, right? 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 there are several possible causes of system failure described above, the most common is a lack of refrigerant. The amount of refrigerant in an air conditioning system naturally decreases over time, but this happens very slowly. However, there may be leaks in the system. If your car's air conditioner is not blowing cold air, you need to run a system diagnostic. It must be carried out by a person certified to work with heating, ventilation and air conditioning systems.
