Why is the air conditioner heating loud, and what is the reason for the loud heating sound of Gree a

The reason why the air conditioner is making a lot of heating noise is most likely due to the following two situations:

1. The wind speed of the air conditioner is too large.

The main noise of the air conditioner is the air outlet of the air conditioner, when the air conditioner is turned on, the greater the wind speed, the noise value of the air conditioner will gradually increase, which is one of the main noise values of the air conditioner.

2. The air conditioning panel is loose.

When the air conditioner is used for a long time, the panel of the air conditioner is easy to loosen due to various reasons, so that the vibration generated by the air conditioner during operation will make the panels rub against each other, resulting in noise.

The solutions to the problem of air conditioning heating noise are:

1. Clean the air conditioner filter regularly.

It is recommended to clean it once every half a month, because if the filter screen is not cleaned for a long time, the filter screen will be too dirty and the air inlet will be blocked, which will not only make the internal unit noisy and the wind speed cannot be raised, but also make the indoor unit evaporator when the outdoor ambient temperature is not too low.

Frequent standby due to overheating protection affects the use of air conditioners.

2. Check whether the inner cover is tightly covered.

Sometimes, after cleaning the filter or after cleaning, the inner unit is not tightly covered, resulting in the vibration and sound of the air conditioner when it is working, which only needs to be adjusted to prevent the sound of the air conditioner.

Here's why the air conditioner makes a lot of heat:

1. When the air conditioner is heating, the outside machine will work, and the air conditioning system will be in full operation, so the sound will be relatively loud. This is because the compressor itself is noisy, and the noise of different air conditioners is different, which cannot be avoided, but this possibility is relatively small.

2. It may be that when the air conditioner starts or stops, the sound generated by the collision of the plastic in the inner machine due to the change in temperature is a normal phenomenon.

3. It may be that some pipelines are deformed due to heat, expansion and contraction, and when they are attached to the compressor or metal shell, they will cause resonance, resulting in noise.

4. Check whether the internal and external units are fixed and strong on the wall, if the fixing screws are loose, it will also cause the air conditioner to vibrate and make loud noises when working.

5. Check whether the connecting pipes between the indoor and outdoor air-conditioning are fixed, and whether they have collided with the indoor and outdoor units or other objects.

6. It is also possible that the refrigerant in the air conditioner makes a louder sound before reaching the equilibrium, and the air conditioner cannot reach the balance when the air conditioner is turned on and stopped.

7. When the fan rotates, it may rub against the outer wall, causing the fan to wear out and make noise from the outer wall, so it is necessary to adjust the distance between the wind speed and the outer wall in time.

8. It may also be that the fan is stuck, and the fan operation is blocked, causing the fan to make a sound, and adding some lubricating oil to the wind speed shaft to maintain the free rotation of the wind speed.

9. It may also be that the rubber pad of the air conditioner compressor is aging and causes the rubber pad to harden and produce resonance.

The sound of the air conditioner when heating is mainly because its appearance is mainly composed of clinker, due to the reason of cold expansion and heat contraction, the body will be slightly deformed and will make a sound, which is a normal phenomenon, and it will disappear after a period of use.

Among the internal components of an air conditioner, the compressor is a key core component. The user finds that the air conditioner is not heating, if it is not an operation error, then it is very likely that the compressor is malfunctioning.

To judge the failure of the compressor, the user can judge whether it is a fault by listening to the sound of the compressor element rotation, if it is a humming sound, then it is normal. If it's a dissonant sound like a knock and a click, it's a malfunction.

The air conditioning heating process is:

First of all. The four-way valve of the external unit is opened to the heating side.

The compressor external fan works.

Run for a period of time (the length of time depends on the ambient temperature.

Adequacy of freon.

and the power magnitude is different.

There is no power on auxiliary heat.

There are differences) after the inner fan starts to supply air.

As the indoor temperature slowly rises.

When the indoor temperature reaches the set temperature, the external unit will be shut down.

The length of time depends on the ambient temperature.

Adequacy of freon.

and the power magnitude is different.

There is no power on auxiliary heat.

Room seals are not the same.

There are differences.

The indoor temperature slowly drops.

After the temperature is lower than the set temperature.

The machine is working again.

And so on, the process is similar to the work of a refrigerator), and when the outdoor unit frosts to a certain point, it will automatically frost.

The four-way valve of the external unit is the refrigeration mode.

The compressor works.

The external fan stops running.

After defrosting, the four-way valve switches to heating mode.

The external fan starts to do work.

The compressor stops for a while in the middle and then starts working again.

If the temperature is set high.

It's going to be warmer indoors.

It could be a problem with the compressor.

The power consumption of the air conditioner itself is large, because the outdoor temperature is low during heating, and the indoor evaporation needs to be used to generate heat through this process, and the air is compressed to a certain volume. So there will be noise.

It may be because the electrical appliances in the air conditioner, such as the motor, will produce some electromagnetic noise; Or if some parts of the internal machine are not well coordinated, the smoothness may resonate and cause a lot of noise.

Solution: You can try to check whether the bracket of the air conditioner is stable, and the position of the air conditioner can be adjusted and fixed to ensure that the outside unit is placed horizontally, and then the fixing bracket of the air conditioner can be tightened.

Extended information: The types of household air conditioners are divided into many kinds, including wall-mounted air conditioners, vertical cabinet air conditioners, window air conditioners and ceiling air conditioners, but these products have their own characteristics, and they are also different, so they should be selected according to their own needs.

The installation of the indoor unit of the air conditioner is connected with the outdoor unit, and the connection between them will also affect the use of the air conditioner and the operation of the outdoor unit of the air conditioner, and the installation of the indoor unit of the air conditioner is not stable enough, and the indoor unit connected by the copper pipe will be affected by the air conditioning compressor when the outdoor unit of the air conditioner is running, resulting in the resonance of the indoor unit.

Recently, some customers have reported that their Gree air conditioner is loud when heating, which affects the comfort of living. This is actually a common phenomenon, because the medium that needs to flow inside the air conditioner increases during heating, resulting in an increase in the noise of the air conditioner. But don't worry about cover leakage, this is a normal phenomenon and will not affect the service life and stability of the air conditioner.

If this is not acceptable, you can put the air conditioner close to the window or doorway to increase air circulation to reduce noise. You can also contact professional technicians for repair and adjustment.

The high heating sound of Gree air conditioner may be due to the following reasons:

1.The pipe connection between the outdoor unit and the indoor unit is not tight, or the pipe leaks, causing air to enter the pipe and form bubbles, resulting in noise.

2.The air conditioner's indoor unit filter is not cleaned, causing the fan to clog or the filter to block, causing noise.

3.Dust or dirt accumulates on the surface of the evaporator and condenser of the indoor unit of the air conditioner, resulting in poor air circulation and noise.

4.The air conditioner compressor is aging or damaged, resulting in louder noise during heating.

It is recommended that you check the above reasons, and clean and replace the corresponding parts in time to ensure the normal operation of the air conditioner and reduce noise. If the problem cannot be solved, it is recommended to contact a professional technical staff for maintenance.

When the Gree air conditioner is heating, both the indoor unit and the outdoor unit will produce noise. If the noise is too loud, it may be caused by damage or loosening of a closed part of the indoor unit or outdoor unit.

Indoor unit installation problems: If the indoor unit is installed in an incorrect position or unstable installation, it may also cause excessive noise cracking during air conditioner heating.

<> why is the heating of the air conditioner more noisy than the refrigeration: because when the air conditioner is heating, the outside will have a defrosting state. During the defrosting process, both the internal and external fans will stop running.

Only the compressor of the external unit is running. However, if the compressor does not run the fan, it will cause the unbalanced operation of the external unit, and the unbalanced operation will cause the noise to increase.

This answer is applicable to Midea KFR-26GW N8MJA3 &&& Gree KFR-35GW NHA1BAJ and other brands of air conditioner models.

The air conditioner makes an unusually loud noise when heating, which may have the following situations:

If the filter is dirty or the inside of the indoor machine is too dirty, it is recommended to clean it.

There is a foreign object or damage to the air seepage wheel or fan of the indoor unit, which needs to be repaired or replaced.

The connection pipe between the outdoor unit and the indoor unit is too high or too low due to aging, damage, fluorine leakage, etc., and needs to be repaired.

Heating pipes that are too long or bent too much lead to excessive resistance and need to be rearranged.

It is recommended that you check whether the filter and indoor unit of the air conditioner are clean, and whether the wind wheel or fan is stuck or damaged by foreign objects. If you can't solve the problem, you can contact the air conditioner maintenance personnel for inspection and repair.

If there is a lot of noise when the air conditioner is heating, it is most likely due to damaged or dirty parts inside the air conditioner. To clear the hole are some of the solutions:

1.Clean your aircon filter retarder: Dirty filters can block air circulation and cause increased noise, so they should be cleaned or replaced regularly.

2.Clean the inside of the air conditioner: Sometimes dust and dirt accumulate inside the air conditioner, which can also cause noise. You can ask a professional to clean it before accepting it.

3.Check the internal parts of the air conditioner: If the parts inside the air conditioner are damaged or loose, it will also cause noise. Damaged parts can be inspected and repaired or replaced by a professional.

4.Adjust the air conditioner hanger: If the air conditioner hanger is unbalanced, it will also cause noise, which can be adjusted.

If the above methods do not solve the problem, it is recommended to contact a professional for inspection and repair.

If the air conditioner makes a loud noise when heating, it may be caused by the following reasons:

There is too much dust inside the air conditioner, and dust or dirt is attached to the fan blades, radiators and other parts, so it is necessary to clean and maintain the limb luggage.

The compressor or motor in the air conditioning unit is faulty and needs to be repaired or replaced.

The pipeline connection between the indoor unit and the outdoor unit of the air conditioner is not firm and the branch is delayed, and the speed of the fan is too high, resulting in vibration and noise.

Solution: Clean the air conditioner regularly to remove the dust inside.

If the air conditioner is seriously faulty, you should seek professional repair and replacement.

The pipes and joints between the indoor unit and the outdoor unit should be adjusted to prevent vibration and noise.

What's going on with the loud external heating unit of the air conditioner? Hear what the repairman has to say.

2. The loosening of the air conditioning panel is also the main reason for the high noise of the air conditioner.

3. The installation of the indoor unit of the air conditioner and the connection of the outdoor unit also affect the timing, use and noise of the air conditioner.

The noise of Gree air conditioner during heating will be the reason for these two aspects:

1. It may be a normal wind sound. This is generally not a problem.

2. Other abnormal sounds:

Solution: It is easy to have problems with the electrical components of the internal machine, and the most is the motor, which produces some electromagnetic noise, which sounds very uncomfortable and squeaky.

If some parts of the internal machine do not fit well, resonance may occur.

It may be the noise caused by the flow of refrigerant in the pipeline. Because the indoor unit may have to intercept the flow, it is also auspicious to control the flow speed of the refrigerant, so that noise may be generated when the flow rate is fast.

There is no way to repair the air conditioner when compressing the noise of the outside unit itself. Recently the principle of the basic day air conditioning, and then complete other reasons.

3. Four-way valve failure, usually occurs during heating, four-way valve is not good suction, gas or stuck, resulting in poor heating performance, in the judgment of the four-way valve can be broken early to listen to whether the suction is good, in the maintenance can be repeatedly energized to the four-way valve or gently knocked on the four-way valve to reset.

4. Check valve failure, check valve is directly conducted during refrigeration, but the refrigerant should pass through the auxiliary capillary during heating, when the check valve is not tightly sealed or the auxiliary capillary is blocked, the heating is affected, so if the air conditioning refrigeration is normal but the heating is poor, the check valve should be checked after eliminating the problem of the four-way valve.
