In summer or winter everyone needs an air conditioner in their house, to make the most of your «air conditioning», it is all year long! However, in order to keep your air conditioning for long-term use, it is necessary to follow some tips.


Operating principle

Air conditioners operate on the simple principle of heat transfer. It is therefore responsible for transferring the heat contained in the room outside or to another place where this heat will be reused.

For heat transfer, air conditioners use a “cooling” liquid, called liquid or freon refrigerant, which absorbs heat by evaporating and returning it by condensation to a private circuit.


There are 2 types of air conditioners

The monobloc (monolithic) air conditioners suck the calories contained in the room where it is placed to extract them, through a heat pipe, towards the outside. Relatively quiet (looks a bit like a refrigerator), it only allows the air conditioning of a small room and only requires an electrical outlet and a window ajar to operate.

There are two types of monoblock air conditioners: fixed monoblock air conditioners, which are installed directly in the room near doors or windows and electrical outlets; portable air conditioner, equipped with casters requires no special installation and follows you wherever you go. The main advantage of this type of air conditioner is obviously the simplicity of installation. There is no need for an expert to install it, so there is no additional cost.

In addition, when using the wheel, the part is quickly and easily refreshed. Prices are affordable and maintenance is easy. The major drawback is its limited power. Large rooms will not benefit from optimal air conditioning.

The split air conditioner consists of two separate but yet interconnected units: the evaporator located in the room to be cooled and the condenser located outside. However, the wall must be drilled to pass through the pipe. So-called reversible air conditioners can also produce efficient and economical heating in winter.

There are two types of air conditioners: the Portable Splitter usually equipped with wheels and the Fixed Splitter. Because of its complex installation this model usually costs a little more but its most valuable advantage is undoubtedly the much lower noise compared to the case of monoblock air conditioners. It also allows you to refresh several rooms at the same time.

The air conditioner noise is mainly generated by the compressor and air flow. In fact, the air conditioning compressor is located in the outer block, outside the house. Its role is to vacuum, compress and then pump the refrigerant back to the condenser.

The noise it produces is related to the action of the pistons and the circulation of air in the pipe. The condenser cooling fan also emits noticeable noise and, to a lesser extent, small drops of condensate strike it during operation, causing the characteristic slight cracking.

In general Cracking noise is caused by the contraction of the material at the start of the compressor and is related to the production of your air conditioner.


Dust filter

Air conditioners move air, so it is normal for dust to build up on the air conditioner filter over time. This accumulation of dust has the potential to create abnormal noises.


Damaged turbine

Does the noise from the turbine persist despite the inspection of the previous step? Most likely, the fan is deformed or damaged, creating a loud vibration noise. You will probably have to change a room. To do this, disassemble the housing of your air conditioner (don’t forget to unplug the unit), then remove the turbine, usually accessible from below.


Pipe expansion

Can you hear a slight squeaking in the pipe? This noise is caused by the expansion or contraction of the tubes due to the change in temperature. If these noises happen occasionally, there’s nothing to worry about. If not, you’ll need an electrician.


The pipes are too close

Do you hear vibrations or clicks? Your air conditioner works by circulating refrigerant. This liquid circulates in closed pipes. If the pipes are too close together, they may start to vibrate or even make a rattling noise.

After removing the air conditioner cover, you can follow the pipes to verify this hypothesis. Otherwise, you can try to gently spread the space between the tubes.


Pipe noise

Do you hear a hum in the pipes of your air conditioner? Sometimes the coolant circulation produces a hiss, a whisper or a wave. These sound effects are quite normal and indicate fluid circulation in your pipes. However, if you hear them frequently and become increasingly noisy, you need to contact a professional to have them repaired.

It is important to note that noise is subjective and therefore its interpretation may vary from person to person.

If your air conditioner makes a noise that seems unusual to you, it may mean that there is a problem with your installation. Therefore, noise can come from equipment (indoor and outdoor units) or electrical installations.

To determine its origin, first try to determine its origin, namely on the inner unit or on the outer unit.

Also check under what conditions this noise occurs (for example, the indoor unit is on or off but the outdoor unit is on or off). Once you have identified the source, we will ask you to contact your specialist so that an inspection of your equipment and installation can be carried out.
