Why the wall-mounted format is the most common

Of all the types available, the wall-mounted air conditioner is by far the most popular format in homes. The indoor unit is fixed high on the wall, above a door or a window, and spreads air evenly from top to bottom. Compared with cassette, ducted or floor models, the wall-mounted unit requires simpler installation, takes up very little space and suits almost any room. If you want to compare the whole range, you can start from the air conditioners page and then narrow your choice down to the wall-mounted format.

Wall-mounted mono and multisplit: which to choose

The wall-mounted format comes in two main families. The wall-mounted monosplit connects a single indoor unit to a single outdoor unit and is the ideal solution for cooling one room, such as the bedroom or the living room. When instead you want to cool and heat several rooms with a single outdoor motor, choose a multisplit system with two or more wall-mounted units.

Looks and quietness of wall-mounted units

Modern wall-mounted units are designed to blend into the décor: slim lines, white or matte finishes and compact profiles that go almost unnoticed, even above a cabinet or a bookcase. Acoustically, high-end inverter models work at very low noise levels, often around twenty decibels at minimum speed, an ideal value for the bedroom and for night-time. Brands such as Daikin and Mitsubishi Electric are valued precisely for their quietness and attention to design.

Where to install the wall-mounted unit

The position of the indoor unit makes the difference to comfort. The best wall is one free of obstacles, high up, so that air can spread without hitting people directly. Here are some practical criteria:

  • Avoid placing it above the bed or the desk, so you do not get the airflow blowing straight at you.
  • Choose a wall near the outside, to reduce the length of the piping to the motor.
  • Leave clear space above and to the sides of the unit, so as not to obstruct air circulation.
  • Favour a perimeter wall, which is simpler to connect to the outdoor unit.

How many BTU you need for your room

The power of the wall-mounted unit is chosen based on the square metres and the insulation of the room. In the catalogue you mainly find these sizes:

  • 9000 BTU: rooms up to about 25 m², such as bedrooms and studies.
  • 12000 BTU: rooms from 25 to 35 m², such as medium-sized living rooms.
  • 18000 BTU: rooms from 35 to 50 m² and open-plan spaces.
  • 24000 BTU: very large rooms and big floor areas.

If you prefer a more discreet look on the ceiling, consider instead the cassette monosplit units, while for those who cannot install a fixed unit there remain the portable air conditioners.

The best brands available in wall-mounted format

You find the leading manufacturers in the sector in wall-mounted format, with official warranty and available spare parts: Samsung, Hisense and Midea, besides the already mentioned Daikin and Mitsubishi Electric. Prices for wall-mounted units start at around 220 euros and reach the highest-performing solutions, for every budget need.

Smart comfort and related solutions

Many wall-mounted units are compatible with voice and remote control. If you are looking for a system manageable with a voice assistant, look at the smart air conditioners with Alexa and Google Home. To integrate hot water production with a heat pump, you can consider the heat pump water heaters, while for current prices check all the offers.

Frequently asked questions

Why is the wall-mounted unit the most popular format?
Because it combines simple installation, moderate cost and minimal footprint. The indoor unit is fixed high on the wall, leaves floor and furniture free and suits almost any room, from the bedroom to the living room.
What is the difference between wall-mounted monosplit and multisplit?
The wall-mounted monosplit connects a single indoor unit to one outdoor motor and is perfect for one room. The multisplit connects several wall-mounted units to a single outdoor motor, so you cool two or three rooms with one outdoor unit.
How quiet is a wall-mounted unit?
High-end inverter models work at very low noise levels, often around twenty decibels at minimum speed. That is an ideal value for the bedroom and for night-time use.
Where is it best to install the indoor wall-mounted unit?
On a clear wall and high up, away from the bed or the desk to avoid the direct airflow. Better a perimeter wall near the outside, to reduce the length of the piping to the motor.
How many BTU do you need for a 25 m² room?
For a well-insulated room of about 25 m², 9000 BTU are usually enough. For larger rooms, poorly insulated or very exposed to the sun, it is best to go up to 12000 BTU.
Can wall-mounted units be controlled by voice?
Yes, many models are compatible with Alexa and Google Home or with dedicated apps. You can turn them on and off and adjust the temperature from your smartphone or with a voice command, even when you are not at home.
