Air conditioners often have a bad image. They use a lot of electricity, are relatively expensive and are usually uncomfortably loud, it is said.
But there are also some exceptions. Therefore, in this article we will look at how you can find the quietest possible air conditioner that suits you.
Why you should buy an air conditioner sooner rather than later
Let’s just say what it is like: When it’s really hot outside in summer, all you need is an air conditioner to lower the temperature in the apartment quickly and significantly.
There are some helpful tricks on how you can cool your apartment in summer even without air conditioning , but these tips will no longer help to the desired extent in extreme heat.
So an air conditioner has to be found, and now.
Unfortunately, however, it is often the case that during periods of extreme heat, most air conditioners are sold out. We have already experienced this several times ourselves.
If you want to have it nice and cool in your apartment in summer, you should therefore already have money in hand before the heat gets up and buy a mobile air conditioner.
Before the summer you still have a large selection, during the summer mostly not anymore.
Quiet mobile air conditioners in comparison
In the following we take a look at some particularly quiet mobile air conditioners that are still powerful.
At this point we are deliberately concentrating on quiet monoblock air conditioning units . In other words, devices that consist of a single unit and where all components are built into one housing.
Split air conditioning systems, which consist of an indoor and an outdoor unit, are usually significantly quieter in the interior, but unfortunately structural changes have to be made for installation of such systems.
You don’t usually do that on the side.
A monoblock air conditioner, on the other hand, can be put into operation immediately after purchase. It is only important that you lay the exhaust hose out of the window and seal it off a little.
Let’s get started, now it’s getting nice and cool:
De’Longhi PAC AN112 Silent
With the De’Longhi PAC AN112 Silent, you can tell from the name that it is an air conditioner that is as quiet as possible.
The manufacturer specifies a noise level of at least 47 and a maximum of 50 dB (A) . These are excellent values.
In fact, we have not yet found a device that could undercut these low values again.
Despite this low noise emission, the PAC AN112 Silent offers a maximum cooling capacity of 2.9 kW / 11000 BTU / h and, according to the manufacturer, is suitable for rooms up to 110 m³.
The other properties are also impressive. The device scores with simple operation, an LED display, De’Longhi Real Feel technology and energy efficiency class A +.
In addition, the Pinguino PAC AN 112 works with the natural coolant R290, which has no influence on the greenhouse effect.

De’Longhi Pinguino PAC EX120 Silent
The De’Longhi Pinguino PAC EX120 Silent also has the magic word “Silent” in its name, which indicates that the manufacturer has tried to reduce operating noise.
De’Longhi specifies a sound pressure level of at least 49 and a maximum of 53 for this device . Again, these are excellent values that are only slightly above the previous model.
This compact air conditioner is designed for rooms up to 110 m³ and has a cooling capacity of 3 kW / 11500 BTU / h. So here you could add a little shovel again.
The elegant look of the device is already apparent at first glance. The clear control panel including the LED display also makes this model quite impressive. Those who love it a little stylish in their own four walls are well served with this device.
The features and functions of the device also make you sit up and take notice.
The Pinguino PAC EX120 Silent offers a fan and dehumidifier function, a 24-hour timer, a Bio Silver air filtration system, Real Feel technology, a reduced ventilation speed for particularly quiet operation and of course the aforementioned strong cooling capacity of 3 kW.

How is the volume of air conditioners measured?
As with other devices, the volume of air conditioners is measured in decibels (dB).
Our article on sound level meters has a handy table that lists typical sound levels for various events .
Using this table, you can compare the sound levels given by the manufacturers with known events in order to get a better feeling for the volume to be expected.
As an example: 60 decibels corresponds roughly to the volume of a television at room volume.
Air conditioner measuring the volume
We wanted to know how loud our De’Longhi Pinguino PAC N82 Eco air conditioner is.
To do this, we let the device run on medium level and measured the volume with a sound level meter at a distance of approx.
As you can see in the photo above, we measure a value of 56.5 dB (A) in this constellation.
In this situation the air conditioner measured a room temperature of 26 degrees and a desired target temperature of 24 degrees was set. The fan was still running at full speed because the device still had some work to do.
What should you look out for when buying a quiet air conditioner?
If you are looking for a quiet air conditioner and you have already looked at some models, then you have surely noticed some common properties of such devices.
Below you will find a summary of the most important properties that you should look out for when buying.
Functions
Sure, an air conditioner should be able to cool naturally. But many models can do a lot more. For example, heating, ventilating and dehumidifying.
On particularly humid days, for example, it is very pleasant when the device dehumidifies the air. You no longer feel like you are in a hot laundry room.
Cooling capacity
The cooling capacity of air conditioners is usually given in BTU or BTU / h. This abbreviation stands for “British thermal unit” and is a unit of energy.
It is defined as the thermal energy required to heat a pound of water by 1 degree Fahrenheit.
1,000 BTU / h corresponds to 293,071 watts.
It is also common to specify the cooling capacity in kilowatts (kW).
The following applies to both units: the higher the value, the higher the cooling capacity. Using these values, you can easily compare the cooling performance of different devices with one another.
volume
Based on the specification of the sound pressure level, you can see how loud the device is likely to be in operation. So this is the most important value to identify a quiet air conditioner.
You can also use this value to compare the volume of different devices with one another.
The following applies here: the lower the value, the quieter the air conditioner works.
mobility
An air conditioner is of course particularly practical when it is as mobile as possible. Because this way you can always operate the device in the room in which you need it.
For example, alternately in the living room, in the study and in the bedroom. Therefore, make sure that the air conditioner is equipped with practical castors so that you can easily and quickly roll it into any room.
service
Since air conditioning units usually have very manageable setting options, operation is usually relatively easy.
However, we would make sure that the device has an easy-to-read display and also comes with a practical remote control.
Timer / time control
If you want to switch your air conditioning on or off automatically at a certain time, you should pay attention to the timer function or the time control.
Because there are actually devices with 24-hour and 12-hour timers.
Room size
In order for the air conditioner to work efficiently and to really cool your room down as desired, the device must match the size of the room.
For example, if the device is designed for a room size of 30 square meters, but you operate it in a room that is twice as large, then the air conditioner can of course not cool the room properly.
But be careful: sometimes square meters (㎡) and sometimes cubic meters (m³) are given for the room size. You shouldn’t confuse that.
We have repeatedly read reviews in customer reviews complaining that the air conditioner cannot cool the stated room size at all.
On closer inspection, however, it is noticeable that the manufacturer had specified cubic meters (volume), but the customer was referring to square meters (surface area).
In this regard, misunderstandings can easily arise if one is not careful. And that quickly leads to an unsuitable device being bought.
Length of exhaust hose
If you buy a mobile air conditioner, you usually have to lead an exhaust hose to the outside during operation. This is usually done through the window.
These exhaust hoses are relatively thick and not particularly long, which is why the device must always be located very close to the window.
Before buying, make sure that the exhaust hose is long enough so that you can set up the device properly.
Refrigerant
The refrigerant R290 in particular has recently become very popular for use in mobile air conditioning units.
This is specially purified and optimized propane, which is considered environmentally friendly and has no significant direct greenhouse effect.
You can find more information about propane in mobile air conditioners in this article from Kälte Klima Aktuell .
R290 is used as a refrigerant in all of the air conditioning units presented here.
Who is a mobile air conditioner suitable for?
A mobile air conditioner is suitable for all those who want to cool their home easily and without great effort and who want to operate the device flexibly in different rooms.
No structural changes are necessary to operate such a mobile monoblock. Only the exhaust hose has to be hung out of the window.
It is also practical that such a device can simply be placed in the basement, in the attic or at another location after the season, so that it does not take up any space in the living room.
Conclusion
Unfortunately, mobile air conditioners for the home cannot work silently. The technology simply does not allow that.
If you want to cool your apartment in midsummer, you have to accept a certain level of noise.
However, there are quite a few differences in volume between the various devices.
In this article we have presented mobile air conditioners that have addressed this problem and try to work particularly quietly.
And that actually makes a difference in practice.
