The type of technology used by the manufacturer can help you in your choice. Manufacturers are constantly innovating and offering more and more advanced, environmentally friendly units. Check the type of technology and favor models with low energy consumption. For your comfort, choose quiet units. Your air conditioner should be able to act as a heater during the cold season, generating warm air to heat the rooms.
The choice of an air conditioner that can cool and dehumidify the air can be interesting, especially if you live in a hot and humid region. Brand-name models offer a variety of features. The best air conditioners with an ionizer mode can purify the air in the room, thanks to the action of negative ions.
Some models have electrostatic air filters to remove dust and bacteria. Units equipped with an activated carbon filter have the advantage of eliminating bad odors. Check the features offered by the manufacturer: depending on the climate and the ambient temperature, it may be wise to choose an air conditioner that can be used in ventilation mode.
The cooling capacity of the air conditioner determines the unit's ability to cool your home. If the wattage is underrated, the unit must run much longer to achieve cool air in the rooms. If you choose a unit that is too powerful for the size of your home, it will have a significant impact on your electricity costs. In order to properly evaluate the necessary power, it is recommended to carry out a thermal assessment, which will take into account various parameters: the number of occupants, the dimensions of the rooms, the insulation, the sunshine, the height of the ceiling...
To
ensure the longevity of your wall-mounted air conditioner, regular maintenance is essential. Before you buy, ask about the availability of replacement parts. The quality of the after-sales service is also a factor to consider. Major brands usually have a strong service team and can take care of your operating problems quickly.
Thenoise emitted by an air conditioner is an important parameter, on which the comfort of use will depend. Be aware that the packaged air conditioner will be noisier than a wall-mounted air conditioner, with a sound level between 50 and 70 dB. The split air conditioner has a sound level between 45 and 55 dB. If the unit is to be installed in a bedroom, choose a model with the silent option. With this feature, the noise level is gradually reduced to below 20 dB.
Air conditioning should be serviced regularly to ensure proper operation. Failure to do so can result in increased energy consumption.
Cleaning the air filters is one of the most important steps in maintaining an air conditioner. It should be done every 2 weeks. During the maintenance, you may be able to change air filters that are in poor condition.
Before servicing the air filters, remember to turn off the air conditioner's indoor unit and unplug it.
Wall-mounted air conditioners with extra modes can keep your space comfortable year-round. In addition to cooling, the most common additional mode that customers look for is "heating" mode. Many wall air conditioners offer extra heat during the winter months and typically use electric heat or a heat pump to provide heat.
Electric heat uses an internal coil to produce heat and a fan to disperse it throughout your space. A heat pump is the opposite of an air conditioner: it transfers heat from a cooler area using mechanical energy. Because heat pumps move heat instead of creating it, they are generally more efficient than electric heating systems. Electric heaters tend to be more reliable and are popular in areas of greater climate change.
The heating mode is not intended to heat your entire home and should be considered as supplemental heating for specific rooms. The other most sought after modes in a wall air conditioner are :
Wall-mounted packaged air conditioners are an attractive solution for older buildings where planning does not allow for the installation of an external condenser. The wall-mounted packaged air conditioner attaches high on the wall and two air pipes are routed from the back directly through the wall.
The disadvantage of all types of packaged air conditioners The disadvantage of all types of wall-mounted split units is that they are slightly deeper than wall-mounted splits, because the condenser is contained within the wall unit. They usually have a heat pump so that the air can be heated in winter and cooled in summer. The best cheap air conditioners Are often one-piece wall-mounted air conditioners
Thistype of wall-mounted air conditioner does not have quick-connect interconnecting pipes supplied with the air conditioner, which means that the installation of the wall-mounted unit and outdoor condenser is custom-made for the building, making it necessary to hire a professional .
Although the installation of these air conditioners is quite costly, the advantage is that the installation is neat and fits the building perfectly which inevitably increases the resale value of the building. There is a wide variety of engineered wall-mounted air conditioners on the market, so there is a wider choice of capacities, features and aesthetics.
In contrast toengineered air conditioners, so-called "easy-mount" air conditioners come with the piping and interconnecting cable in a plastic sheath or "umbilical cord" that has a quick-connect end. The system, including the tubing, is pre-charged with refrigerant and is designed so that the unit can be installed by you even if you're a bit handy with DIY.
However, recent regulatory changes require that these now require installation by a qualified refrigeration engineer. This change has meant that the choice of this type of split air conditioner has decreased, mainly because if it has to be installed by a refrigeration engineer, it is actually more expensive than an engineered model.
The electricity required for its operation is generated by photovoltaic solar panels. The device is then connected to the solar cables. One of the main advantages of using a solar device is, of course, that the energy source is free. Another advantage is that the solar air conditioner is environmentally friendly and does not pollute the atmosphere. It uses refrigerants, which are present in cold production systems.
It combines the functions of heating and cooling. Better known as an air-to-air heat pump, the device allows for significant energy savings. It can be used all year round, in winter and summer. During the cold season, the calories in the air are captured by the outdoor unit. The warm air is then distributed through the rooms. In summer, the indoor unit expels the warm air into the house.
The choice of a wall-mounted air conditioner can be quite difficult, given the various technologies embedded in the most recent models. However, for the more eco-friendly, solar-powered units are to be preferred. On the other hand, if you want both heating and air conditioning, the reversible one is ideal.
Quickly controlled temperature
Because it is positioned close to the ceiling where heat and moisture wander, a wall-mounted air conditioner works efficiently. In no time at all, it can cool or heat any room to the temperature you want. It then maintains that temperature throughout the day.
Easy to install
A wall-mounted air conditioner can be installed as part of a new build or as part of a renovation to replace your heating system. There is no need to call in an engineer or a specialist in the field to set it up. Moreover, it does not require major structural work. In addition, an installation manual is included with the unit.
Small footprint
Today's wall-mounted air conditioners are increasingly compact and discreet, taking up little space. It is available in several shapes that come in neutral or coloured designs. It will be easy for you to find a model that will blend in perfectly with your interior decoration.
Silencer
Thanks to advances in technology, wall-mounted air conditioners are also getting quieter. Long gone are the ranges that emitted very high levels of decibels. In order to optimize acoustic comfort, today's air conditioners run almost inaudibly. This allows you to work well during the day and sleep better at night.
Adjustable air flow
Do you want to send the air through the whole room or directly to you? Thanks to the horizontal and vertical slats, the air flow can be controlled. You can regulate the air direction with the remote control according to your wishes.
Economical
A wall-mounted air conditioner consumes little electricity thanks to its coefficient of performance of between 4 and 5. You can control the power of your unit with other well thought out features to reduce energy expenditure, while optimizing comfort and having well sanitized air.
In our opinion, the best brands of wall-mounted air conditioners (stationary air conditioners) in 2022 are :

The diagram below will help you to get an idea of the typical prices for each price range (entry-level, mid-range and high-end).
However, more expensive does not necessarily mean better.
We therefore advise you to always consult our ranking before deciding, rather than blindly relying on price ranges.
Do not use your wall-mounted air conditioner too frequently
When you constantly run your wall air conditioner, your body will start to get used to the coolness of the air. As a result, you will feel a big difference in temperature between your indoor and outdoor environment, and this may affect your health. Because of this, it would be better to limit the use of the air conditioner.
Save on the consumption of your wall air conditioner
The air conditioner is only useful when you are at home. If you're out running an errand or going to work, it's out of the question to leave it running. This will save you money on your electric bill.
Remember to maintain your air conditioner by calling a professional
It is true that some maintenance of your air conditioner is your responsibility, such as regular cleaning of the air filters and the outside of the unit. However, it is necessary to have it checked by a certified professional at least once a year. The indoor unit of your wall-mounted air conditioner should be placed at a minimum height of 2 meters, on a sturdy support. Also, the air diffusion should not be hindered or directly directed to people for their own health. As for the outdoor unit, it should be installed vertically in a place protected from wind and heat.
How to position your wall-mounted air conditioner
There are various ways to cool your home without using air conditioning. First, be sure to open the windows in the early morning and at night when the wind is cool. You can also use blinds to prevent the sun from heating your windows. Having green plants in your home is also a great way to lower the temperature.
Cool your home even without air conditioning
The best wall air conditioner depends on your needs and budget. Read our buying guide to find out which products are the best at the moment.
A wall-mounted air conditioner works by drawing warm air from the room into the unit. The warm air that enters the unit is led over the air conditioning evaporator and will be cooled. The cooled air is blown back into the room. The air conditioner pushes the warm air from the condenser through the vents on the back of the unit so that it does not heat the room.
Overall, wall-mounted air conditioners are quiet comfort solutions. Designed to be installed in bedrooms, hotel rooms, dorm rooms, assisted living facilities and more, they are designed for situations where noise levels are important. Some wall-mounted units are as quiet as 50 dB, which is about as loud as the refrigerator in your kitchen.
A wall-mounted air conditioner is a good choice for cooling a room if you don't want to board up the window or if a particular room has no window. They are reasonably energy efficient and have a wide range of capacities. If you don't have an existing hole in the wall, the unit may require professional installation.
Installation involves drilling a hole in a wall to mount the air conditioner. Brackets or sleeves are used to support the weight of the unit. Once the air conditioner is installed in the wall, it is plugged into the nearest electrical outlet and a weatherproof stripping is placed around the air conditioner to prevent outside air and water from entering the building.
