Reasons for split ac unit noise

The sound of the air conditioner can indicate the correct or incorrect operation of this system. Undoubtedly, the abnormal sounds that come out of your air conditioner indicate a problem in the system that should be investigated quickly.

Why does the air conditioner work with a lot of noise?

If you hear a howling sound from your air conditioner that easily distracts you, probably a part in this system is not working properly. So it is better to control the following:

Internal panel ventilation fan

If the ventilation fan of the internal panel of your split air conditioner is not balanced or does not work properly, especially if the bearing on its sides has a problem or is even out of place, you will naturally encounter the sound of the internal part of the split air conditioner.

Error in the compressor

The compressor in the air conditioner is one of the most important parts of this device, which is responsible for compressing the refrigerant gas in the system. The buzzing sound in the device means that the compressor is not working properly or the amount of electric current in the circuit is not suitable.

The base is detached or damaged

The compressor in the air conditioner is on a small rubber base. With continuous use of this system, this plastic support cracks, falls apart, and eventually causes the balance of the air conditioner to be lost and creates noise when the system is working.
On the other hand, the nuts and bases of the device's external unit may be loose. In this case, solve the problem of the sound of the air conditioner by pulling a wrench.

Frozen split ac unit

Even if your air conditioning system is used during the hottest time of the year, you may see ice on the system. Freezing is the result of refrigerant gas leakage and can become one of the reasons for the noise of the air conditioner.

The presence of loose parts

There are various parts in the air conditioner, the damage of each of them or their loosening causes the parts to wear on each other and finally the noise of the air conditioner.

The presence of a foreign body in the condenser of the air conditioner

It may be that the air conditioner is working when you suddenly hear a sound from it. If the external unit of the system is installed in outer space, the probability of the presence of a foreign body in it increases.
In this case, you should turn off the device and disconnect its power. Then look inside the unit and if there is any foreign object or animal or bird, remove it from the unit.

The device is not level

During the installation of the air conditioner, you should pay a lot of attention to its alignment, because if the device is not aligned, it will cause the system to make noise over time. In this case, you should contact the air conditioner installer to solve the problem.

Lack of machine lubrication

Lack of lubrication of the device is one of the reasons for the sound of the air conditioner. To solve this problem, you must turn off the device to prevent damage to it. Then call an HVAC professional to lubricate the system.

Breaking fan blades

A foreign object can damage the fan blades. The presence of curvature and warping of the fan blades disrupts its efficiency and ultimately causes the noise of the air conditioner.

The front frame of the system

If the front door of the air conditioner panel is not closed properly or is loose, a rattling sound will be heard while the air conditioner is working. To fix this problem, close the front panel frame gently.

Other sounds that may be heard from the air conditioner

Just because your air conditioner is making noises doesn't mean your system has a problem. But it's a good idea to call an HVAC professional when you hear these sounds:

Clicking sound: When the system is turned on or off, this sound is completely normal, but if it becomes a continuous sound, it will be a warning that the relay is faulty.
Noise: hearing noise from the system means that the capacitor has a problem and the motor of the system may even need repair.
