The air conditioner has no heating in winter, and there is no cool breeze in summer, what is going o

Check the sheet metal to see if there is any air leakage. If the warm air is not hot and the water temperature does not go up, it is possible that the water pump is broken, or the thermostat is broken. The air conditioner is not cold, check the pressure of the air conditioner, whether it is a lack of fluoride, you can consult the store where you buy the air conditioner.

Check the temperature, if the set temperature is too high, the ambient temperature is too low, the air conditioning compressor does not start, there is no cool breeze, and the most common reason is that the refrigerant leaks almost.

There is no warm air in the air conditioner in winter, and there is no cool breeze in summer, this may be a problem with your air conditioning program, generally speaking, there are cool breezes and warm air, this can be repaired.

The following points need to be checked when the air conditioner is not cooling:

1. Whether there is a refrigerant in the system, if not, it needs to be pressurized to check the leakage, and then add enough.

2. If there is refrigerant, check whether the compressor is working. If it is not working, you need to check whether there is any problem with the air conditioner pressure switch, temperature control switch and its wiring.

3. Check the heat dissipation of the air conditioner to see if the fan is working. Clean the condenser.

4. Replace the air conditioner filter, the filter element is too dirty, and it will also cause no refrigeration.

If the air conditioning compressor starts normally and exhausts normally, it is estimated that there is a problem with the refrigeration in the air conditioner, in other words, there should be little refrigerant left, contact the customer service of air conditioning maintenance, determine the reason, and replace the refrigerant in the future, and the problem should be solved.

Home air conditioner, what use do you still use it, it may be broken.

If an air conditioner does not have a warm air in winter and no cool breeze in summer, it means that the air conditioner is broken, and it is recommended to change the air conditioner.

It may be that the freon is not enough, you can ask a professional person to repair it!

1.Air conditioner leakage or lack of fluorine.

If the reason why the air conditioner is not cooling is because of the lack of fluorine, this situation will generally occur when the air conditioner has been used for three or four years or even longer, which is very normal because it is normal consumption. Even if you are deficient, it will not be completely uncool, and it will not be much worse than usual. At this time, it is good to add enough fluoride.

2.The air conditioner voltage is insufficient.

Sometimes we will encounter some tricky problems, such as the air conditioner is not cool, but it is normal when we check it, but we can't find the problem. Until the final inspection, it turned out to be a voltage problem, especially during peak electricity consumption periods. This phenomenon is even more pronounced.

3.The air conditioning was not powerful enough.

Insufficient power of the air conditioner is also a reason why the air conditioner does not refrigerate, but there are many reasons for this problem. For example, install a low-power air conditioner in a relatively large house. Sometimes the power of the air conditioner and the size of the room seem reasonable, but the house is too poorly sealed or there are some other heat sources, resulting in no cooling, etc.

Maintenance during general air conditioning.

1.Remove debris from the vents to ensure proper ventilation. Observe whether the outdoor rack is loose, and clean the outdoor ventilation grille for foreign objects. At the same time, keep the vents open.

2.Clean the surfaces of indoor and outdoor heat exchangers to improve the efficiency of heat exchangers. When cleaning the indoor heat exchanger, the panel should be carefully removed, scrubbed with a soft rag, and gently scrubbed with a small brush to remove dust and harmful deposits that can multiply germs.

However, because the heat sink is made of thin aluminum, it is easy to deform after being stressed, so it should be brushed carefully.

3.Remove dust from the filter. When cleaning the filter, cut off the power supply first, and then open the air intake grille; Remove the filter and clean it with water or a vacuum cleaner.

The water temperature should not exceed 40 degrees. Wash with a hot, damp cloth or mild detergent, then wipe with a dry cloth. At the same time, the filter should not be cleaned with pesticides or other chemical cleaners.

Then determine which part of the machine is not normal. For example, if the internal and external units are not working, whether the control part is normal, if the machine is operating normally but is not refrigerated, then suspect whether there is a refrigerant problem. Judging from what you said, there is no condensate discharged from the indoor unit, which may not be refrigerated.

The pipeline of the external unit has a low temperature, which means that there is still a refrigerant. If the power cord is not unplugged for a long time, it may damage the control circuit of the machine. 1. The air conditioning mode is set on ventilation.

2. The starting capacitor of the external compressor is broken. 3. The air-conditioning and refrigeration system lacks refrigerant (freon). 4. The tube temperature sensor of the evaporator of the internal machine is broken.

According to the above relevant information about how the air conditioner is not refrigerated, it is not possible to immediately determine the cause of the failure, or report to the maintenance department of the repair manufacturer for on-site inspection.

The temperature is set to 26 degrees, and the air mode is hot air.

The air conditioner without air conditioning will generally be: the power of the air conditioner is small, the refrigerant is not enough, the air conditioner is not cleaned for a long time, and the plug is loose.

1. The power of the air conditioner is small.

The reason why the inverter air conditioner is not refrigerated may be that the power of the air conditioner is not enough, which is also a common problem of the air conditioner not being cooled. There are many reasons for this, such as: using low-power air conditioners to cool large areas of the room; Although the power of the air conditioner matches the area of the room, in the process of using the air conditioner, the air conditioner will also be insufficient because of the lack of sealing of the room itself and the number of heat sources.

2. The refrigerant is not enough.

If the refrigerant in the air conditioner is insufficient, it will also cause the Gree air conditioner to not refrigerate. The refrigeration effect of the air conditioner will decline after a long period of use, and the refrigerant will also volatilize in the long-term use, and if the refrigerant leaks, it will also lead to insufficient refrigerant in the air conditioner.

3. The air conditioner is not cleaned for a long time.

If the air conditioner is not cleaned for a long time, thick dust will accumulate on the radiator of the outdoor unit and indoor unit of the air conditioner, resulting in the poor heat dissipation effect of the radiator of the air conditioner, thus causing the air conditioner to not refrigerate. If the air conditioner is not cleaned and maintained for a long time, it will also make people prone to air conditioning disease.

4. The plug is loose.

When the inverter air conditioner is not refrigerated, check whether the power plug of the air conditioner is not plugged in properly, the power plug of the air conditioner is not plugged in well or the power plug is loose, which will cause the air conditioner to not run, of course, it cannot be refrigerated.

For details, please call us or make an appointment for maintenance.

1. The set temperature is not lower than the actual temperature of the roomThis is due to the setting of the air conditioner itself, because the compressor will automatically shut down when the air conditioner reaches the set temperature.

2. Whether the compressor is running normally；This is because it is impossible to refrigerate the compressor if it is not running.

3. The compressor cannot be refrigerated after runningThis may be due to the drop in refrigerant (fluorine) pressure (fluoride leakage), if this situation occurs, it is recommended to find the relevant maintenance master to add it.

4. Whether the function setting of the remote control is wrongYou can select either the air supply mode or the dehumidification mode in the mode selection, so the air conditioner will not cool.

5. Ensure the stability of the voltage at home, especially during the peak period of electricity consumptionBuy a higher resistor and voltmeter to monitor the voltage at all times.

Related Notes:

There are many reasons why the air conditioner is not cold, such as insufficient freon, insufficient power supply, insufficient power of the air conditioner or the air conditioner is not cleaned and maintained for a long time, etc., which will cause the air conditioner to not be cool.

When the ambient temperature is about 35 degrees Celsius, the air conditioner has low pressure, high pressure or more, and the static pressure is the situation, which generally occurs in the old air conditioner that has been used for three to four years. The air conditioner did not completely stop cooling, but the effect of cooling decreased.

This is because old air conditioners use freon as a refrigerant, which will volatilize after long-term use. Therefore, users only need to add a little to the regular air conditioning maintenance point. In addition, it is not excluded that improper installation can cause freon leakage and problems with the machine itself.

The reasons why the air conditioner is windy but not cool are as follows:

Reason 1: Freon is not enough (commonly known as fluoride deficiency).

Most of the reasons for this non-refrigeration are the air conditioners that have been used for three or four years, and most of them are also a normal phenomenon, which belongs to the normal consumption of air conditioning refrigerant (that is, we often say freon or refrigerant) after long-term use, but this is only manifested in the fact that the air conditioner is not refrigerated enough compared with the previous normal situation, and it will not be completely uncooled.

Because it's just that the pressure is not enough, it won't be too far from the normal value, so you just need to make up for it; Of course, there are also refrigerant leaks due to installation reasons or the machine itself, which is a common and relatively easy to find reason, and this kind of problem is relatively easy to deal with. Use a pressure gauge to check the pressure, if it is not enough, just add it.

Reason 2: The voltage of the power supply is insufficient.

The power supply voltage is unstable, and it often fails to reach the normal voltage, especially during the peak of electricity consumption. The manifestation of this problem is: when the voltage is normal, the air conditioner is also normal, and when the voltage is unstable, it will affect the air conditioner when it is not cold.

Reason 3: The power of the air conditioner is not enough to not refrigerate.

This is also one of the reasons for a common non-refrigeration (poor refrigeration effect), but there are many reasons for this non-refrigeration, such as: small power air conditioning pipes in a large area of the room, and some although the air conditioning power and the room area seem to match, but because the room is relatively unsealed, or there is a heat source in the room (such as a computer), of course, the glass room is also one of the heat sources. This kind of situation is something that we tend to ignore.

Reason 4: The air conditioner is not refrigerated due to the high ambient temperature.

The outdoor unit is installed in a relatively closed space or the temperature around the outdoor unit is too high. For example, in order to look beautiful, some real estate units are installed in a hidden small space or even multiple outdoor units in a small space, so it is extremely easy to cause no air circulation in the small space where the outdoor unit is located.

There is a common saying that when the outdoor temperature exceeds 43 degrees, most air conditioners are difficult to transfer indoor heat to the outdoors through the radiator of the outdoor unit, and even cause high-voltage protection, which will also cause the air conditioner not to refrigerate.

Reason 5: The air conditioner is not cleaned and maintained for a long time.

Since the outdoor unit is installed outdoors, it is easier for everyone to ignore it, and the outdoor unit will absorb a lot of dust and garbage and other dirt on the radiator after a long time of use, so that the heat dissipation effect of the radiator is poor and the air conditioner is not refrigerated. In addition, ignoring the maintenance of the air conditioner for a long time will make the air in the room unhygienic, increase the power consumption, and shorten the service life of the air conditioner.

There are many reasons why the air conditioner is not cool:

1) Fluorine leakage at the connecting pipe joint.

2) There is a leakage point in the connecting pipe.

3) The wiring is incorrect.

4) Fuse burning.

5) The compressor is faulty and the starting capacitor is damaged.

6) The external environment temperature is high, and the indoor personnel are more than the United States, and the air conditioner is working at full load.

7) If the power supply voltage is too low, the air conditioner is not easy to start, and it will stop or the fuse will blow after starting, so it is recommended that the user install a power regulator.

8) The air outlet of the air outlet is not large if the temperature does not drop in the strong cold block room, which is the air filter has too much dust, clean the filter.

9) The thermostat is improperly adjusted.

10) The installation position of the air conditioner is not good, which will lead to uneven indoor temperature or poor refrigeration effect.

Maintenance of air conditioners during general hours:

1. Remove the debris from the vent to ensure normal ventilation. Observe whether the outdoor rack is loose, and clean the outdoor ventilation grille for foreign objects. At the same time, keep the vents unobstructed.

2. Clean the surface of indoor and outdoor heat exchangers to improve the efficiency of heat exchangers. When cleaning the indoor heat exchanger, you should carefully remove the panel, scrub it with a soft rag, and use a small brush to gently scrub the heat exchanger of the internal machine, so as to achieve the purpose of removing dust and harmful accumulation of multiplying germs. However, it should be noted that since the heat sink is a thin aluminum material, it is easy to deform after being stressed, so it should be carefully brushed.

3. Clean the dust on the filter screen. When cleaning the filter, first cut off the power supply, and then open the air inlet grille; Take out the filter, wash the filter with water or a vacuum cleaner, the water temperature should not exceed 40 degrees, wash it with a hot damp cloth or neutral detergent, and then wipe it with a dry cloth, and do not wash the filter with insecticides or other chemical detergents.

Here's why:

1. Insufficient refrigerant.

The common reason why an air conditioner doesn't blow cold is that the refrigerant is insufficient. When the air conditioner is in refrigeration mode, you can check the high and low pressure conduits in the compressor for condensation. If there is no condensation in the conduit, refrigerant needs to be replenished.

2. The voltage is not enough.

The lack of voltage is also one of the reasons why the air conditioner often does not blow cooling. The normal operation of air conditioners in China needs to keep the voltage constant. If it is lower than the rated voltage of the air conditioner, the air conditioner compressor cannot do more work, and the refrigeration effect of the air conditioner will be greatly affected.

3. Dust blockage.

If the air conditioner is not cleaned for a long time, a large amount of dust will accumulate inside the air conditioner, which may cause dust to block the air outlet of the air conditioner and the air conditioner cannot be cooled. The air conditioner needs to be cleaned regularly, especially the filter with the most dust at the air outlet.

Common treatments

The principle of refrigeration is to transfer the indoor heat to the outside with a radiator, if the radiator is not cleaned regularly, there will be a lot of dust on it, resulting in it not being able to dissipate heat normally, and the effect of refrigeration will be reduced.

Observe whether the outer rack is loose, and clean the ventilated grille for some foreign objects, and keep it ventilated. When cleaning the filter, first cut off the power supply, take out the filter, clean the filter with water, the water temperature should not exceed 40 degrees, clean it with a thermoneutral detergent, and then wipe it dry with a dry cloth. It is easy to accumulate dirt when draining, so be sure to disinfect it regularly to ensure smooth drainage and prevent bacteria from multiplying.
