Air conditioning in your carWorking properly - amazing thing. However, when dealing with (which, of course, it happens certainly on the hottest day of the year) it turns into a real mockery - a warm, fume air begins to the salon. If the air conditioner of your car is faulty, then you better not postpone the visit to the service workshop.
Automotive air conditioning systems Have a rather difficult design, which predetermines the complexity of their repair without the availability of the necessary equipment and special knowledge. In addition, increased environmental requirements for the refrigerant, which is used in the system. We have allocated 3 the most common faults of the air conditioning system so that you have an idea of \u200b\u200bthe reasons for its failure.
1.
The refrigerant leakage itself is a unique phenomenon, since when pressure drops, it instantly turns into gas. Closed air conditioning systems in cars are securely sealed and do not require refueling. With an insufficient refrigerant volume in the system, we can conclude about the presence of leakage that needs to be eliminated.
Leaks from the air conditioning system do not lead to the formation of the puddle under the bottom of the car, as it happens with antifreeze. And only a professional mechanic is able to find practically imperceptible signs of tightness impairment, such as oil deposits on tubes connections. The refrigerant leak can also occur in the compressor, condser and / or evaporator, that is, in almost all elements of the system. For their detection, and refueling uses special equipment, including use of ultraviolet radiation, which allows you to qualitatively diagnose and maintain your car.
2. Air conditioning car compressor wear.
The compressor is the heart of the air conditioning system. Its function is to ensure the circulation of refrigerant for an effective heat dissipation from the cabin. Like many other automotive spare parts, the air conditioner compressor is wearing over time. Due to the complexity of the design, the compressor may fail if contaminants come into it or when there is a breakdown of other system elements.
How to extend the life of the air conditioner compressor.
There are several ways to extend the life of the 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, as in most modern cars it is included in conjunction with the heater. Another way is the constant diagnosis of the air conditioning system that professionals must perform.
3. Air conditioning electrical system faults.
The air conditioning system includes many electrical wires, fuses, relays and pressure regulators, the coordinated job of which ensures the safe and efficient operation of the air conditioner. At the failure of any of these elements, due to wear or defect, an automatic shutdown of the entire system is provided for security reasons. Without special equipment and, more importantly, the necessary knowledge and experience to diagnose these problems is very difficult.
Air conditioning devices are installed in order to create comfortable conditions in the room. Their main task is air cooling. The heating function was considered secondary for a long time. But today the leading manufacturers have changed approach to this issue. It turned out that heating mode could be very useful when coldly occurred, until the main heating is turned on. But sometimes there are situations when the system begins to work incorrectly. Why does the air conditioner do not blow with warm air? The reason may be the wrong mode of operation or breakage of one of the cooling design elements.
Heating air
In order to find out for what reason the air conditioner works incorrectly, it should be understood how it carries out the heating of air masses. Indeed, initially, the main function was considered the cooling mode. It turns out that the design of individual mobile systems includes heating ceramic elements. In this case, their functioning is similar to the operation of a conventional heater. The disadvantage of such devices is the great consumption of electrical energy.
Modern models are used when heated air and another principle of operation. Inside design, the cooling substance changes the circulation direction. The condenser and evaporative element change their roles. Air conditioning begins to cool out external air masses. In this case, warm air enters the room.
Functioning of the cooling device at low temperatures, possible consequences
If the air conditioner does not blow with warm air, it should be understood whether it is capable of working in a similar mode. Not all designs can heat the air indoors with the onset of winter frosts. Standard cooling systems operate in heating mode only to a certain value of a negative temperature. Usually this value should not exceed -5 ° C.
When using such devices under conditions of lower temperatures, the probability of problems occurs significantly:
- the oil in the compressor becomes more viscous;
- the cooling substance changes its properties;
- dry launch of the compressor can lead to its breakdown;
- work in extreme mode leads to rapid wear of parts and failure of the entire system.
On the surface of the heat exchanger with the occurrence of frosts sometimes appears ice crust. She periodically melts. Water flows into the pallet. In it is formed to go out. This can lead to a fan breakdown. In addition, the ice deforms the walls of the heat exchanger, leading to the depressurization and leakage of the working substance.
Since heat enters the room from the external environment, then with a decrease in temperature, the working conditions are hampered. Air conditioner requires a greater amount of energy to heat the air. When a certain limit is reached, it can simply turn off and stop working.
Usually in the technical characteristics of the device, the temperature interval is indicated, 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 improper operation of the system in heat transfer mode, ways to solve the problem
The following reasons for the poor quality of the cooling device in heat transfer mode may occur:
- ice plugs appeared in the connecting tubes. They impede the movement of the working substance. Detergenting over the winter period is not possible. It is impossible to warm the main line. To solve the problem, switch operating modes. This changes the direction of movement of the cooling substance. The external module is heated;
- in the air conditioner lacks freon. Such a situation may arise in the case of a tightness and leakage of a gaseous substance. Wizards are invited to eliminate the fault. After finding distressed areas, he closes them and fills the system to the desired level;
- dirt appears on the surface of the internal details. It is necessary to periodically remove the decorative lid of the device and clean the main elements and filters;
- a breakdown of certain parts of the structure can occur. Usually in this case, a malfunction code occurs on the control panel. To restore the cooling device, the service wizard is called.
Sometimes immediately after turning on the instrument, it turns out that it does not work in heating mode. How to make the air conditioner blowing warm? Do not immediately fall into panic. Such a functioning mode is associated with a change in the direction of movement of the cooling substance. This requires a certain time. Also, if there is a negative temperature on the street, the compressor must gain momentum. Be patient and wait.
Use of inverter structures
As mentioned above, classical air conditioning devices are not sufficiently adapted to work in heating mode at low negative temperature. They decrease the efficiency, the heat loss increases. The risk of breakage of the compressor is increasing.
Inverter models can be more efficiently used for the heating of the room, even with sufficiently severe frosts. There is a way that increases the efficiency of work. The flow of external air masses is mixed with air in the room. In heating mode, it is necessary to compensate for a smaller temperature difference.
Winter sets of equipment can be used to improve the operation of air conditioners in the winter period. They consist of the following elements:
- devices heating the drain system and external connecting tubes;
- Teni, heating fan and compressor;
- a device for automatically adjusting the engine speed when the temperature parameters change.
The installation of the winter kit allows you to prevent the external module breakage, when it is turned on in boundary conditions and prevents ice in the drain tube.
Is it worth using air conditioning for heating room
The use of coolant for the heating of the room has a number of advantages:
- there remains enough moisture in the air;
- carbon dioxide does not stand out;
- thermal return is larger than the amount of electrical energy consumed;
- the room improves microclumatic conditions.
But along with advantages there are certain negative moments:
- significantly reduces the service life of the air conditioner;
- oil thick thick, its characteristics deteriorate;
- The efficiency of the device becomes less nominal value;
- the risk of failure of the cooling device increases.
The heat transfer equipment for air conditioning is quite high and economically justified. Modern models are able to operate at low negative temperatures. But they are only an addition to the system of basic heating.
How unpleasant to detect the owner of such wonderful climatic equipment as air conditioning his breakdown! Especially if the air conditioner in the midst of the summer did not just stop cooling the room, but began to blow warm or even hot air.
Unfortunately, this kind of malfunction is most often due to improper air conditioning care. Its necessary clean regularly From dust and dirt on their own, as well as invite the masters for holding a deeper and full cleaning, preferably once a year.
On time to clean the air conditioner is not too costly in time, nor for money occupation. But if this is not done, it will take more complex and expensive repairs.
Causes and types of breakdowns
The air conditioner blows with warm air when the heat exchanger of the external unit and the filters of the indoor unit are clogged by the accordion, octoch, dirt, dust and other things flying from the street and falling out of the room, trash. As a result, the air conditioner compressor overheatand blows warm. In the end, at one fine moment, the compressor can jam.
Do not delay with solving the problem of the air conditioner blowing the warm air, because the harder the repair, the more expensive it is.
Types of repair work in the case when air conditioning blows with warm air:
- cleaning air conditioner
- repairs compressor
- replacement compressor.
To perform these works, order the air conditioner repair service in the company SERVERMONT24! An experienced and competent master will quickly and efficiently cope with any task.
In addition to the problems described above, the air conditioner breaks:
- Problems with electricity, namely, low voltage in the power grid or a faulty socket.
- Out of system control boards.
- Disadvantage freona in system. This problem can also provoke the failure of the compressor. So far, it did not happen, refueling the unit by Freon. In addition, Freon is quite toxic gas.
Unfortunately, often even during the wrong or inaccier installation of a new air conditioner, a breakdown occurs, leading to a gas leakage. As a result, you may not have time to enjoy the cool air conditioner, as you have to repair it.
Undoubtedly, it is better not to wait when the problem of Freon's lack will manifest itself in one or another malfunction, and order Refueling air conditioner refrigerant In the company NEXTMONT24 in about 1-3 times every three years.
As can be seen, the problem is that the air conditioner has become a blowing air, only an experienced and qualified master can solve. However, before contacting the company SERVERMONT24, check if the cause of force majeure is common inattention.
Is the temperature on the air conditioner? Is it worth heating mode (heat)? 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 due to the battery controls in the remote control on it, you see some numbers and values, and in fact they are different.
In any case, you can be calm. The Master Demonstream, who came to you at home will find and quickly eliminate the fault of the air conditioner of any model and brand.
The exact cost of repair is determined by the wizard after the preliminary diagnosis.
All kinds of work performed and installed components will be provided with a guarantee.
Although in modern models of air conditioners and split systems, heating mode is provided, still most users use technique only in the summer to cold. Therefore, the equipment has a period of downtime. But the hot time began, you turned on the air conditioner after the winter and found that:
- split system does not cool, and blows warm air;
- the climate surmator started, worked and stopped cooling, now the air conditioner blows warm, and the room temperature does not fall.
We have prepared an article about the reasons because of which air conditioning blows, but does not cool the air to help you understand the situation and decide whether to call the masters.
Does the air conditioner really do not cool? We carry out diagnostics
Before looking for a problem in a split system, check the external causes that are not related to the equipment. In addition to the cooling capacity of the air conditioner itself, the room cooling affects:
- The time of operation of climate techniques.Customers often forget that when the air conditioner turns on, it does not cool the air indoors instantly. For a tangible decrease in temperature, you need 10, 15, 20 minutes. Depending on the size of the room, the temperature on the street and inside and the power of the split system.
- Compliance of the power of the split system by external parameters.Air conditioning of small power will naturally not be able to significantly cool the spacious room when it's hot on the street, and the room is greatly warmed. When choosing equipment, it is often overwhelmed that the load can be peak, and the air conditioner must be taken with the reserve "power".
- Isolation of the room.Air conditioning in the apartment will be bad, if there are "holes in tightness" of the room: open windows, doors operating a ventilation system. Additional influx of heat outside or forced outflow of cold air from the room are the reasons that lead to weak cooling.
- "Blocked" input or air output, another reason. Obstacles in the form of curtains, blinds, furniture interfere with normal air circulation and, as a result, cooling.
If the power is enough, the input and yield is free, the windows-doors are covered and enough time passed, but it did not become more cooler, it means that you need to diagnose the equipment. Simply put, measure the air temperature at the air conditioner and the outlet.
The inlet temperature is measured by air intake solutions. Put the thermometer on the housing or hold in your hand. The output is measured in the jet outside or slightly extinguishing the thermometer inward through the blinds.
Attention! Do not push the thermometer deep into the housing. It can get under the blades of the fan.
In a serviceable air conditioner, the temperature difference at the "input-outlet" is within 7-15 degrees. If you just turned on the air conditioner for maximum cooling, and the differential turns out less than these values, it means that your split system is badly calculating due to some internal reasons.
In addition, you can reflect the output flow temperature with passports. Usually in the passport of the equipment indicate the temperature of the cooling mode at the output, for example, 6-14 ° C in non-inverter systems. Inverters, when turned on, give the same parameters, and after reaching a given temperature in the room slightly raise the value at the output - up to 12-17 ° C of degrees. If the output stream temperature exceeds the passport, then you should look for a problem inside the air conditioner.
Air conditioning blows warm air, what problems can be eliminated yourself
With part of the reasons for bad cooling, you can handle yourself. The table contains the main ones, and recommendations on the elimination of the equipment failure are given.
| Sign | Possible reason | How to fix |
| Air conditioning well cools the room. | Installed high temperature in the settings. For quick cooling, it is recommended to choose the minimum. And then switch to comfortable. | Adjust the cooling mode. |
| Air conditioning is turned on, but does not show. | The fan mode is selected. And the air simply circulates without cooling. | Select the cooling mode. |
| Air conditioner blows with heat (for models with heating mode) | Enabled heating mode by mistake. | Set the cooling mode. |
| Cooling is weak. It may leak and / or freeze the internal unit of the air conditioner. | (coarse and fine cleaning). Dust, wool, hair clog filters and settled on heat exchanger plates. Because of which worsens the heat from the evaporator: the radiator does not give a cold in the air, which leads to weak cooling. With severe contaminatedness of the inner block, the evaporator tube can freeze. Dust can also clog the drainage hose, then condensate will remain in the pallet, and then drip from the inner block. |
Clean the filters. To get them open the block cover. How to do this, described in the instructions. Then pull the filters and rinse well under the rods of cold water and install clean in place. Attention! It is impossible to use hot water, filters can be deformed.If you are afraid of "climb" into the internal unit of the air conditioner, call the wizard. |
| Bad cool, shutters a compressor in the external block. | The radiator of the external block is dirty. On the heat exchanger, dust accumulated, fluff from plants, raising from the "exhaust" of vehicles, a fan rotation may be difficult. All this worsens the heat transfer 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. | You need to clean the external block. You can use a steam generator, a sink with pressure or mechanical means (brush, sponge). If the house is a multi-storey - industrial climber services may be required. |
| Blowing warm air. The split system compressor, which is in the external block, is silent or turn on for a short time (2-3 minutes) and turns off again. |
Low voltage in the network. The lack of voltage often leads to overheating of the rotor winding and the motor disconnection along the thermal relay. |
Set the voltage control relay. It can be put separately or paired to the stabilizer. |
If the elimination of these problems has not improved the situation and cooling, is still weak or absent, it means that the problem is in the nodes and parts of climatic equipment. In this case, complete diagnosis is required by a specialist and service repair.
Do not cool air conditioning in the apartment - the reasons that require professional service or repair
Signs of faults are similar, but they occur due to wear or malfunction of parts, damage, internal contamination of nodes and mechanisms. According to the experience of repairing air conditioners, the "Rembyttech" masters compiled a list of basic equipment breakdowns.
| Sign | Possible reason | Repair or replacement | Cost* (only work) |
| The air conditioner is poorly blowing and coolly cools. Water can drip from the inner unit of the air conditioner, and the vapor tubes can freeze. |
Internal block filters clogged (coarse and fine cleaning). Dust, wool, hair clog filters and settle on the heat exchanger. The heatsel from the evaporator is worsening, and the radiator does not transfer the cold flow through it through it. In addition, the strong pollution of the inner block may prevent the fan rotation and lead to the frost of the evaporator tubes. When clogged with drainage hose, condensate remains in the pallet, and then follows from the inner unit. |
Cleaning filters, after removal. When the evaporator and the fan is contaminated, the entire internal unit is disassembled, to clean the nodes. |
from 1900 rubles. |
| Air conditioning after the winter blows normally, but coolly cools. | In the air conditioner insufficiently freon. Even in a hermetic system, up to 7% refrigerant per year can evaporate. Therefore, climate equipment requires annual maintenance (cleaning, refueling). | Freon refueling is carried out. | from 2.300 rub. |
| By blowing there, but cooling is weak or not. The first time the compressor in the outer unit works without stopping, but the air conditioner, however, is badly cold. Then, the motor ceases to turn on, and the split-system is to chop. On models with error indication, a reduced pressure message appears. |
Freon leakage occurred from the system.At first, with a small leakage of the leakage, the air conditioner compressor, located in the external block, is increasingly turning off on vacation, despite the weak cooling. Then, as the refrigerant evaporates from the system, the equipment begins to blow a warm air of the room temperature, and the motor stops and does not turn on. Usually, the leakage occurs due to the collapse of the jacks of inter-block tubes or the destruction of the mounting seams. |
The master is looking for a refrigerant leakage. Then it seals the flow, the system evacuates (to remove moisture and air) and fills the system by Freon. | from 3400 rubles. |
| It blows fine, the compressor in the outer block is almost not turned off, but the air conditioner does not hide completely or cool the weak. It can also freeze the air conditioner tube to the evaporator. |
Castle of capillary pipelines. Due to the scored capillary tube, the pressure drop at the entrance and the output of the capillary increases, so part of the freon is boiling and gives the cold before the air conditioner evaporator. As a result, the cooling capacity of the split system falls, and the equipment is trying to compensate for its lack of a constant operation of the compressor. When the refrigerant does not circulate, the refrigerant does not circulate, the compressor works in good, the air remains warm. |
A partial blockage is removed by blowing air under pressure. This operation is also called a blockage. Hydraulic cleaning and solvents are used to remove a strong break. In particularly difficult cases, when removing a blockage fails, the capillary tube is falling and soldered a new one. |
from 3900 rubles. |
| Split system blows, but coolly cools. Compressor in the external block occasionally turns off. | The external air conditioner unit is dirty. Dust accumulated on the heat exchanger, fluff from plants, raising from the "exhaust" of vehicles. In addition, the fan is contaminated, and its rotation speed is reduced. All these factors worsen the normal heat from the capacitor, it is badly extinguishing the warmth of the street. Because of what the quality of the cooling of the split system is reduced. The lack of cooling the air conditioner is trying to compensate for the permanent operation of the motor in the external block. | The master is washing and cleans the radiator. In multi-storey buildings, with complex access to the external unit, it is necessary to additionally order an industrial climbing service. | from 2200 rubles. |
| Air conditioning blows hot air when the cooling mode is turned on (in heated models). |
Faulty switching four-way valve.It is in the external block and is responsible for changing heating and cooling modes. When damaged, the valve "encourages" in heating mode. | Repair or valve replacement is required. In some cases, if the heating mode is not needed, the valve is simply falling, and the equipment always operates on cooling. Usually it is done to reduce the cost of repair or in the absence of spare parts (valve). |
from 3500 rubles. |
| Blowing room temperature air. The compressor is silent or disconnected immediately after starting the air conditioner. |
Faulty compressor(in the external block) . Basic breakdowns - jamming, breakdown of windings, engine intervory closure or opening. | Replacing the compressor. In the case of a wedge, it is sometimes possible to repair (you can separate). In some cases, it is advisable to completely replace the external block to a new one. |
from 4200 rubles. |
| Faulty and / or working capacitor(in the external block). The starting capacitor is needed for the initial start of the compressor engine. Working - supports the engine in operating mode and increases efficiency. When the rated capacitance of the capacitor, discharge, the test engine may not start or disconnected shortly after the start. |
Replacing a defective condenser new. | from 1300 rubles. | |
| Breakdown of the compressor thermal(in the external block), which is responsible for the thermal protection of the motor. Because of this, the power supply does not come to the compressor, and it does not start. | You need to replace the thermaller to the new one. | from 1500 rubles. | |
| Blows cold, but it is badly cooled. The split system turns on for a while and quickly turns off at high temperatures in the room and the minimum temperature temperature. cooling. Modern models give the error code. |
Faulty temperature sensor or thermistor.It "monitors" behind the room in the room and is located in the internal block. If you fail, it may "read" the lowered indicators, which is why cooling is turned off ahead of time. | Replacing faulty sensors to new ones. | from 1400 rubles. |
| Faulty evaporator or condenser temperature sensors.According to their indicators, the pressure is regulated in the system for different cooling modes. If any of the sensors erroneously flashes that the required cooling parameters are already achieved, then the air conditioner turns off earlier and without cooling the room to the desired temperature. | |||
| Blowing, but cooling is weak. The compressor in the outer block can work without stopping and disconnecting the thermorel due to overheating. | The fan of the outdoor unit is faulty.Most often the engine is lit, due to dust. This leads to poor heat from the capacitor and weak cooling capacity, its lack of air conditioner is trying to compensate for the constant work of the compressor. This leads to overheating of the motor, and its disconnection by the thermal. | The full replacement of the fan or only its motor is required (if the spare parts for fans are sold separately). | from 1700 rubles. |
| When you turn on the air conditioner blows warm air. | Lost communication between blocks.As a result, external - does not work. Without circulation of freon, the inner block turns into a ventilation device and "chases" the air without cooling. Communication easily disappears in obsolete models. Modern immediately signal the error code when the connection fails and will not work. |
Restore the power of the external block (usually wiring, contact connections). | from 1500 rubles. |
| Faulty control board in the internal unit.The reason can be jammed, punched or burnt elements that run the compressor or the fan of the external block. For example, power relays, amplifying chips. In addition, a microprocessor can go out. | Repair or replacement of the control module is required. The relay can be cleaned if the contacts are connected. Damaged elements are falling and replaced with new ones. With a strong damage to the block, especially due to the burnt chips, the output of the microprocessor needs a complete replacement of the control module. |
from 1800 rubles. | |
| Faulty inverter module (in the external block). It is present only in the inverter air conditioner and is responsible for the power of the compressor. When the module fails, the current of the compressor does not arrive. | It is necessary to replace the faulty module new. | from 2300 rubles. |
* The cost is indicated Just for the work of the master. Spare parts and additional services are calculated separately and included in the total.
In addition to major faults, there are others. To determine exactly what breakdown occurred, the air conditioner is diagnosed. According to her, the master determines the volume of repair and calls the full cost of the service.

Your air conditioner blows warm air, because during the fan operation, something turns off the cooling mechanism. Reasons include simple things, such as thermostat settings and poor air flow, but there may also be problems that can cause large problems, such as electrical problems and refrigerant leaks.
We will start with simple problems that you can fix, and when you need a professional skills to diagnose and correct a greater problem.
1. Troubles with thermostat
If you are worried about your home or air conditioner, blowing warm air, the first thing to check is a thermostat. This is a fact: they are faked, children accidentally fall into it a flying object, or a colleague turns it off due to the fact that it is too cold.
Make sure the thermostat is installed on the Cool, and the fan is on Auto. And, of course, the set temperature is below the actual air temperature.
2. Potted filter
The reduced air flow is one of the most common problems that may prevent the cooling of your air conditioner. Oddly enough, your air conditioner really needs a warm air flow over coils to function normally. The air conditioner filter is designed to remove dust and contamination from the air passing through the equipment. However, the air filter clogged with dust and garbage can completely block air penetration into the system. When this happens, the coils cannot remove heat. Therefore, your system fan simply blows back into your space.
If you didn't have your system for some time, and your AC blows with warm air, the next step is to check the air filter and, if necessary, change it.
3.The autholes are closed or blocked
Here is another problem with an airflow, which can lead to the blowing out of warm air from the air conditioner. Is it possible that the ventilation grilles were closed in winter and never opened? Or (this is common in offices!), Perhaps you have furniture or other obstacles blocking them?
Make sure all registers and returns are open and allow air to flow freely.
4.Ontned or leakage channels
It is also possible that you have problems with an airflow that you do not see ... in your channels. If the channel has holes, cracks or they are completely disconnected, the air may not get to the device. Or the cooled trim air can be ripped in your walls, in the attic or at the bottom, and as a result, the air conditioner blows warm air.
If the channels are available, you can take a look at them. Of course, damage occurs during construction projects, or from birds or rodents ingress. In the second look ... It may be an area where you better get professional help to check the condition of your duct.
5. Potion power for outdoor unit
Many air conditioning systems have an internal evaporator / air cleaner and an external condensing unit. If the air cleaner works fine, the fan still blows the air into your space. But without the work of the condenser block, the cooling will not be; Consequently, your air conditioner blows with warm air.
This script may occur when your condenser block loses power, often due to a blown fuse or a steoted circuit breaker.
IMPORTANT: Never try to diagnose electrical problems yourself, if you are not a qualified electrician or OWK specialist. However, there is one thing you can check: your emergency switch. It may have been accidentally disconnected when the power of the condenser unit is turned off and this can also lead to the blowing of warm air.
6.gish condenser coils
One of the important functions of your condenser block is to highlight heat out from your room. The condenser coil is responsible for this work. Since it is exposed to elements, it can be loaded with dirt and dust, not to mention the leaves and trash. In the end, this prevents the work of coils, and your system cannot cool effectively, so the air conditioner blows warm air.
7. Read more refrigerant
The refrigerant (Freon) is a substance that flows through your air conditioning system, and provokes cooling. This is a closed contour, so you do not need to add a refrigerant if there is a leak in your refrigerant line or coil. When this happens, your system loses the charge of refrigerant and cooling power. Depending on the size of the cooling loss leakage, they can occur slowly or immediately, but ultimately your air conditioner blows with warm air.
