Extraneous sounds during the operation of the air conditioner may be regular or indicate a problem. All climatic equipment operates with a certain noise level. However, the noise of the air conditioner compressor may vary.
Sources of hum
- power;
- operating mode;
- technical parameters of the equipment.
So, inverter systems work quieter and extraneous noise, hum from the air conditioner, practically do not emit cod. The more powerful the model, the louder the noise.
When operating in rapid cooling mode, the air conditioner will hum more than in sleep mode.
The air moving through the radiator creates the same hum, which can be more intense or weaker. This is a homogeneous sound, the power of which is determined in laboratories. Its value is indicated in the annotation to the air conditioner.
Against the background of this noise of the air conditioning compressor, others arise. It is they who disturb the owners and sometimes signal problems. These are clicks, hiss, crackling, buzzing. The reasons for these sounds are varied:
- Clicks are typical for the operation of the relay that turns off and off the compressor, fans and other components;
- The crackle in the air conditioner occurs when heating or cooling the plastic parts of the indoor unit. Plastic deforms and emits a quiet crackle;
- Hissing sounds can be heard when the compressor is starting up or shutting down. When freon changes direction, a hiss is heard;
- The sound of pouring liquid is heard when the heat exchanger is defrosting or the equipment is stopped. It indicates the movement of the refrigerant through the pipes.
As a rule, a hum from an air conditioner of this kind does not indicate a malfunction and accompanies normal operation.
What does it mean: the air conditioner is loud?
The fact that the air conditioner is working loudly can be said if the noise level of the indoor unit exceeds 35 decibels. This is the level of a conversation in an undertone, and such a loudness of the air conditioner can already interfere with sleep.
Crackle from the air conditioner
A crackle in the air conditioner is a reason to urgently diagnose and clean the equipment.
If a crackling sound is detected in the outdoor unit, a specialist will need to check the condition of the compressor. This is the most difficult and costly breakdown. Maybe the problem is in the debris that interferes with the rotation of the fan of the outdoor unit. You can clean the outdoor unit yourself if it is located in an accessible place.
But professionals will handle the procedure better.
If you are worried about crackling in the air conditioner (indoor unit), you should also clean the fan impeller. The blades could get clogged with dust. If the impeller is broken, it is replaced.
Everything that is written here from advice is like from an anecdote; “Did you knock on the wheels? did you wipe the headlights? " All extraneous noises are determined by a simple man at the moment: "to derench something in the tubes" and is never confused with the clicks of the relay, the creak of the bearings, etc. crap. 90% of complaints - gurgling, hissing, clicks - inside the pipes! (I have x-k SAMSUNG from the first day so noisy, bought, did not believe the reviews on the Web - but in vain). Here? split ELENBERG 07, after another service grunted, hissed, began to click like a cockatoo. I wanted to find out the reason on the network, but on all sites the same crap about relays, bearings, wind noise and other electrical mechanics - sites were copied from one source - some textbook or reference and are far from real life: they say that 2x2 = 4 , but do not dig deeper. Around the continuous amateurism!

Hello. Answer the question: I have an air conditioner with a heating function, it worked quietly in the summer, but now it got cold and began to turn on no heat. The first 4 days it worked quietly, and then it began to hum during operation. What is the reason?
Hello Svetlana!
Tell me, what kind of hum?
Perhaps your air conditioner is simply not able to equalize the temperature difference, it is not designed for operation in this mode. First of all, check the documentation.
If the reason is not clear, we can only advise you to call the master, because these problems can only be dealt with on the spot.
In our catalog you can find a list of companies in your city and contact them with this question.
Best regards, Valery.
The air conditioner is designed for heating up to -5 degrees. On the street +11 and at home +16. buzzing as if something prevents him from working at full installed capacity. Thank you.
Call the master, there may be a problem with the filters and it is not possible to take the required volume of air, or maybe there is a problem on the technical side.
Always happy to help!
Can you please tell me why there is a crackling (as if something “shoots”) in the outdoor unit of the split system in heating mode (30 degrees, average speed)? Split system Panasonic CS / CU-YW12MKD.
Hello Sergey!
The most likely reasons are as follows:
- clogging with dust and dirt if it has been operated for a long time without cleaning;
- damage to the fan and it touches something;
- an electrical problem that causes short circuits.
In any case, it is recommended to call a specialist, because using a defective air conditioner can be dangerous. If in the first two cases it can simply break down, then in the case of electronics and a short circuit, there can be dire consequences.
Best regards, Valery!
Hello. Please tell me what could be. The split system works for 1 minute and does not respond to control. At the same time, the outdoor unit buzzes strongly, it seems that the compressor works with both working and starting windings at once. Panasonic nine system. Thank you.
Hello Ivan. In order to avoid damage and risk, we recommend that you contact your local air conditioner installation and service company. You can find these using our service for the selection of contractors on the map. Most likely this is really a compressor, but a breakdown can only be established on the spot.
Thank you so much.
The buzz does not always happen, the specialist called him said the voltage is not enough, but on the stabilizer it shows 220 and still buzzes explain what the matter can be a more powerful stabilizer to buy
There are several options:
-the stabilizer is lying;
-the master is lying;
-you do not catch a specific moment of voltage drop or you find yourself at the moment when the input to the stabilizer is 220, but there is a shortage at the output.
Hello, my air conditioner is cracking, as if the engine touches something, the sound of a helicopter. What is the reason? Maybe it needs to be cleaned? Because of this, the lid has come loose and it also knocks.
Most likely, the impeller is simply clogged with dust, a common problem in any electrical engineering. Try cleaning or blowing with a vacuum cleaner. If the hum persists, we recommend calling a specialist.
Hello, please tell me whether it is necessary to cover the outdoor unit of the air conditioner with a cover against dust and poplar fluff or is this nonsense?
They are equipped with filters that need to be cleaned periodically.If you cover it with a cover on top, you will need to clean it in any case. It can also prevent sufficient air from being drawn in. Therefore, it is not recommended to do this.

Hello. Tell me what to see. Inverter zanussi, external unit, vibrates very strongly when operating on "heat". Cold work is perfect!
Good evening, tell me the reason for the crackling, new split-system, the first day of work, LG smart inverter, I turn on any mode, the first 3 minutes works perfectly, and then a crackle appears, not loud, but like a quiet rattle, unpleasant annoying gradually, and so every time, annoyingly, tell me if anyone has encountered such a problem.
I will add that this crackle is in cooling mode, in fan and heating mode it is not.
Hello. Fuji electronic air conditioner model with a cover that rises upward. The crux of the problem is that in auto modes the air conditioner cooled the room and when it switched to normal operation (quiet), I heard a sound as if a butterfly were beating its wings against glass, a very irritating sound. As I understand it, the impeller does not work well. In general, can an air conditioner work with such an impeller, because Fujitsu is expensive, but I don’t want to suffer with a guarantee, because the air conditioner is located abroad.
Hello.
We have Toyotomi Hiro Inverter air conditioner. The outdoor unit began to make a "cricket" sound. The sound can come and go on its own, but it remains for a long time and especially at night is very annoying. If you just touch the casing with a jar, the sound disappears, but very quickly returns. The master had already been summoned, he came, turned on, there was no sound ... shrugged his shoulders and left.
What to do, the situation is dead end.
Good afternoon, I have a split system Electrolux07. Operated for 2-3 months. In cooling mode, everything is super Noisy outdoor unit, but when the window is closed, I can not hear it. But when heated, the outdoor unit makes a lot of noise, and a crackling sound is heard. This is normal?

Hello. The air conditioner is off. There is a bubbling sound with increasing frequency in the split system unit. True, there is a strong wind outside. Could the reason be that the wind spins the fan and it drives the coolant?
What to put and how rubber gaskets on the cover of the external unit, so that it does not rattle. When the cover is removed, the external unit works perfectly, almost silently.
Please tell me. The air conditioner samsung turned on, there were clicks in the compressor. The condender itself does not cool. There is no condensate. It works for 5 minutes and turns off by itself. What can it be?
Good day. After how many years of operation is it necessary to refill the air conditioner with refrigerant and in what amount? The distance between the indoor and outdoor unit is 2-3 meters.Operation in summer and early autumn, moreover, for a short time and not every day. Toshiba inventory.
