There are many problems with the old air conditioner in my house, especially the noise is getting lo

Noise problem: (if it is an external machine).

1. The installation is not professional enough, the position is not level, or there is something stuck inside.

2. If an object is pressed on or inside the machine, it will resonate when it starts.

3. The walls of the room are hollow bricks, and the sound of the external machine starting is normal, but it can be transmitted to the room, so it naturally feels loud.

If it is the noise of the internal machine)

1. Each customer's feeling of the sound is different, the normal sound of the internal machine is of course the sound of the air supply, it must be smaller than the fan, of course, there is the sound of the air supply, and the fan is divided into three wind speeds, you can choose according to your preferences.

2. The installation position is not level, which may also cause noise problems, please find the seller.

Personally, I don't think there will be any sound from the internal machine.

You can find an after-sales service to check whether you need to clean and maintain.

If it's an old machine, it may be that the parts are aging. If it's convenient, see if there's something blocking the outdoor unit.

**Air conditioning fan, air outlet, air duct will produce noise, you can find a professional after-sales door-to-door look, if it still doesn't work, change it, the current **air conditioning power consumption, noise control is particularly good.

The noise of the indoor unit is mainly the fan, and the noise of the outdoor unit is not only the fan but also the compressor.

The noise problem of air conditioners is more complicated, including fans and compressors. Recommend to you LG's ** air conditioner, the fan motor adopts DC variable speed motor, stepless speed regulation to ensure the stable and efficient operation of the air conditioner, now out of the new fan, this belongs to LG's unique technology, the fan blade wing slightly vortex suppressor greatly reduces the noise level, with high external static pressure technology, so that the air flow through the shroud can be blown out stably in a straight line. The compressor motor, indoor fan motor, and outdoor fan motor all use DC motors, which are quiet and efficient.

When the air conditioner is turned on, there will generally be some sound, which will not cause noise under normal circumstances, if there is a buzzer sound or a creaking sound, it is generally a failureSo why are air conditioners getting louder? What's going on with the air conditioner vent creaking?Let's find out!

Why air conditioners are getting louder

When the air conditioner turns on 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.

1. Air conditioning outlet

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. Loosening of the air conditioning panel

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.

3. Installation of air conditioning indoor unit

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. If the installation of the indoor unit is not stable enough, when the outdoor unit is running, the copper pipe is connected to the indoor unit, and the indoor unit is not stable enough, it will be affected by the compressor, resulting in the resonance of the indoor unit.

What's going on with the air conditioner vent creaking

1. It may be the sound produced when the refrigerant in the air conditioner flows in the pipeline, because the internal unit of the air conditioner sometimes needs to control the flow rate of the refrigerant. If the flow rate is too fast, noise may be generated.

2. It may be that the sound generated by the electrical components of the internal unit of the air conditioner is easy to sound. Under normal circumstances, the motor will produce some electromagnetic noise when it is running, which sounds harsh.

3. If some parts inside the air conditioner are not well coordinated during operation, they may resonate and thus produce sound.

4. Foreign objects can be attached to the fan blades of the air conditioner, and when the air conditioner is turned on to sweep the air, it will collide with the air conditioner fan blade and make a sound.

5. It may be the normal wind sound when the air conditioner is turned on to sweep the wind. In this case, there is generally no problem.

Why air conditioners are getting louderWhat's going on with the air conditioner vent creaking

1. The sound of the compressor is normal, and the vibration of the air conditioner is mostly due to the compressor problem.

2. Loose screws may cause the shell and compressor to stick together, causing vibration and noise.

3. The fan blade of the fan is broken, the fan will be very loud, or the air conditioner heat sink is dusty, which causes poor heat dissipation of multiple heat pipes, which increases the power of the compressor and increases the vibration.

4. If the copper pipe of the air conditioner is compressed, the flow of freon will not be smooth, and it will also lead to the increase of compressor power and violent vibration.

1. Noise caused by non-standard installation: the common ones are loose feet, unstable bracket fixing parts and unlevel installation of external units. The noise caused by such factors is generally tightened to the external unit, and the noise can be discharged by leveling.

2. The loosening of the outer casing causes the joint to collide and vibrate during work to produce noise: the unstable parts can be tightened.

3. The vibration of the press during the operation causes the collision noise between the external machine pipelines: adjust the mutual protection distance between the external machine pipelines or install shock-absorbing cement to eliminate the fault.

4. Noise when the press is working: the performance of the press is poor, and low-frequency vibration hum is produced during work. It can be eliminated by adjusting and replacing the shock-absorbing rubber pad of the press foot, wrapping soundproof cotton, etc.

1. The air conditioner is very noisy, it is likely to be the sound of the compressor, because the compressor is abnormal, the vibration of the air conditioner will become larger, and a lot of noise will be produced when the air conditioner is turned on at this time.

2. It is also possible that some screws inside the air conditioner are loose, causing the shell and the compressor to stick together, and the shell and the compressor will cause vibration when they stick together, so that the shell will also make a lot of noise.

3. It is also possible that the fan blades in the air conditioner are broken, if the fan blades are broken, the fan will be very loud, thus creating a lot of noise.

4. The noise of the air conditioner is very loud, and it is also possible that the dust of the air conditioner heat sink caused by the dust accumulation of the air conditioner heat sink will cause the heat dissipation of many heat pipes to be poor, and the power of the compressor will increase at this time, resulting in very loud noise.

5. If the copper pipe of the air conditioner is compressed, it will cause the flow of freon to be unsmooth, and the unsmooth flow of freon will lead to an increase in the power of the compressor and a violent movement, so that the air conditioner will also make a lot of noise.

6. When the air conditioner makes a lot of noise, we must find the corresponding cause, and then seek the help of professionals, and try not to deal with it at home to prevent damage to the air conditioner.

Is your noise caused by engine shaking? Is it noticeable when idling? If so, then it is necessary to clean the throttle, if the throttle is dirty, it will cause the engine to shake and idle unstable, especially when the air conditioning compressor works to increase the engine load, the noise will be more obvious!

If the noise is not caused by engine shake

1. When heating in winter, the air conditioner will defrost regularly, and the running sound of the external unit will become louder at this time, and the sound will return to normal after the defrosting is over.

2. If the user lives on the ground floor, the user can check whether the fan of the external unit is involved in debris, because the air inlet may absorb some debris floating in the air when sucking air, such as plastic bags. In this case, if the user is outside, he can see the debris, and he can take it out after turning off the air conditioner, such as the debris in the machine, or the user lives 2

When it is upstairs, do not let the user dispose of it by himself. (It also includes small birds to make nests).

3. The noise during heating is greater than that during refrigeration. When heating in winter, the air conditioner needs to draw heat from the harsh outdoor environment, and the condenser needs to have a lower temperature than the outside temperature, which requires a lower evaporation pressure. Therefore, the pressure difference between condensation and evaporation increases, that is, the pressure difference between the compressor discharge and the suction air increases, and the compressor needs more power to overcome this pressure.

As a result, high power consumption is usually required during heating. The power consumption is large, and the noise is correspondingly increased.

The outdoor unit is noisy, and after eliminating the above reasons, you can register the service information and make an appointment for a technician to come to the door to deal with it.

4. Special circumstances: not caused by the air conditioner itself, other sound sources cause user misunderstanding.

What is the reason for the loud noise of the air conditioner? Look at how the master got it, I didn't spend a penny, just adjust it.

To distinguish various reasons, the new machine or the old machine, the installation gap will vibrate, the compressor distance will be close to the sound insulation, if the old machine needs to be maintained and replaced for a long time, if the new machine has three packs, you can contact the dealer to check! Hope it helps.

Saying that the noise is loud, it refers to the internal machine, generally the noise of the fan, or it caused resonance, you can press and hold different positions to check it, to see if it is the sound of the **, as long as it is not the sound of the motor, you can generally solve it yourself.

Check whether the connecting pipes between the indoor and outdoor parts of the air conditioner are fixed, and whether they have collided with the indoor and outdoor units or other objects.

It may be 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, and the internal refrigerant does not reach the balance at this time, and it is easy to make a large flow sound, which is a normal phenomenon.

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

It may be that the fan is stuck, and the fan operation is blocked, causing the fan to make a sound, and add some lubricating oil to the wind speed shaft to keep the wind speed rotating freely.

It may be that the rubber gasket of the air conditioner compressor has deteriorated, causing the rubber gasket to harden and cause resonance.

The outdoor unit contains a compressor, which is the main noise of the air conditioner, so when choosing the installation location of the outdoor unit, you should try to avoid the balcony of the bedroom, study and living room, because under normal circumstances, the insulation and sealing of the large glass door between the balcony and the room are difficult to do a good job, and the noise of the outdoor unit is easy to transmit to the room. At the same time, the outdoor unit should be kept away from the bedroom, study and other areas with high noise requirements. The installation and fixation of the outdoor unit needs to be equipped with shock-absorbing devices such as shock-absorbing gaskets to reduce the impact of air conditioning noise as low as possible.

Answer: Hello, 1. The air conditioner shell is not buckled. Start by reattaching the walling, or treat the wall to keep the panels flat. Check whether the indoor air conditioner shell is buckled properly, and the hood can be buckled.

2. When the air conditioner is started, there is a large temperature difference between it and the room. You can cool down the house first, when the air conditioner is just turned on, you can turn on the high wind speed gear, about 15 minutes of running, you feel cooler and comfortable, when the room temperature gradually drops, you can change to a low wind speed gear.

3. The air conditioner filter is too dirty. The filter screen should be cleaned regularly (should be cleaned once every half a month), if the filter screen is too dirty, the air inlet is blocked, not only will the internal machine be noisy, there is vibration, the wind sound is low, and the wind speed can not be raised, and when the outdoor ambient temperature is not too low, it will make the indoor unit evaporator overheating protection and frequent standby, generally about 10 minutes.

Due to the cost control of enterprises now, low-cost alternatives are used in some components, resulting in a reduction in the service life of electrical appliances, if your electrical appliances have been used for more than 8 years, it is recommended to replace them with new ones, hehe.

Is it an old air conditioner? If not, it may be that the air conditioning radiator is too dirty, and the air circulation of the internal unit is not smooth, which will also lead to the generation of air conditioning noise, it is recommended to buy a bottle of professional air conditioning disinfectant to clean the air conditioning radiator, my family is now using a home air conditioning disinfectant, which is very convenient to use! Just spray the air conditioner and turn on the cooling mode, and the dirt and bacteria will be discharged along the drain.

The cleaning effect is quite good, after washing, the heat sink is clean, and the noise is definitely gone. And as long as it is cleaned once a month, it does not need to be cleaned very often.

Just disassemble the fan and put some lubricating oil on it, and replace it with a new fan if it doesn't work.

2.possible noise from the casing and compressor sticking together;

3.It is also possible that the fan blades in the air conditioner are broken, if the fan blades are broken, the fan will be very loud;

4.It may be caused by the accumulation of dust on the air conditioner's radiator;

5.It may be that the flow of freon is not smooth.

Question: Buzz in the room.

What's going on.

Answer the reasons for the noise of the air conditioner: 1. The performance of the air conditioning compressor is poor, and the low-frequency vibration buzz sound is produced when working, and the press can be adjusted and replaced. 2. When the air conditioner is started or stopped, it is normal for the plastic parts of the internal unit to expand and contract due to temperature changes.

3. The outdoor unit of the air conditioner is too dirty, or there are foreign objects in the case, which rub against the fan and cause noise; Cleaning up foreign objects is fine. 4. Caused by parts, the common is that the compressor cylinder or compressor starting capacitor is damaged, and the damaged spare parts can be replaced. 5. When the fan is running, it rubs against the outer wall, and the distance between the fan and the outer wall should be adjusted in time.

In addition, it is also possible that the fan is stuck, add some lubricating oil to the fan shaft of the air conditioner to ensure that the fan rotates smoothly.

Question: The air conditioner is not on, and there is a humming sound in the room.

In order to enjoy the relevant rights and interests normally, you must ask the professionals of the air conditioning service department to move the machine to the door. 1. Installation of sound absorption, sound barrier in the sound chamber is to insert a facility between the sound source and the sound receiving point, and use it to truncate the direct sound waves from the sound source to the sound receiving point, so that some sound waves are blocked and reflected. The sound waves are absorbed and attenuated (small) and transmitted through the screen, and the additional attenuation form reaches the receiving point, thus reducing the influence of noise on the sound point and achieving the effect of noise reduction.

2. In order to meet the cooling and ventilation volume of the heat pump unit to the greatest extent, and to meet the fresh air requirements and noise reduction requirements of the unit during operation, the installation and exhaust muffler are installed. An impedance composite exhaust muffler is installed on the exhaust port at the top of each heat pump unit to absorb the noise from the exhaust airflow. The exhaust muffler and the exhaust vent of the heat pump unit are connected by an air duct, and a service door is provided on the air duct.

If it's not turned on, there is noise, which shouldn't be the reason for the air conditioning.

Ask what that sound would be.

Buzzing. Answer: Because I don't know what is in your room, can you provide some possible information, ask if there are no electrical appliances in the room, except for the refrigerator, and then the refrigerator listens to no sound, and also asks upstairs, upstairs does not turn on the air conditioner, I don't know what's going on.

If you can't hear it.

Could it be tinnitus.
