Wall-mounted air conditioning (or a wall-mounted split) is the most common solution for homes. The indoor unit is fixed high on the wall and connected to an outdoor unit.
Advantages of a wall-mounted split
Which rooms is it for?
Bedrooms, living rooms, home offices, small shops. For several rooms, a multi-split system connects several wall units to a single outdoor unit.

Placing a wall unit well
- High on the wall, with clear space below the ceiling for air intake.
- Without blowing directly onto a bed, sofa or workstation.
- As close as possible to the outdoor unit, for short and discreet pipework.
- With condensate drainage planned from the start.
Single-split or multi-split?
A single-split connects one indoor unit to one outdoor unit: the simplest solution for one room. A multi-split connects several indoor units to a single outdoor unit, which means fewer units on the façade.

Frequently asked questions
Where should a wall-mounted air conditioner go?
High up on a clear wall, so that air circulates through the whole room without blowing directly on people.
Is a wall-mounted air conditioner noisy?
Modern models are very quiet, with sound levels close to a whisper in night mode.
What capacity for a bedroom or living room?
It depends on the floor area, insulation, orientation and glazing. A bedroom often needs only a small unit, while an open-plan living room needs more. We size the unit when preparing the quote.
Can several wall units share one outdoor unit?
Yes, with a multi-split system: several wall units are connected to a single outdoor unit, each controlled independently.
Does a wall-mounted air conditioner dry the air?
It removes some moisture, which improves comfort in summer. A moderate temperature setting and regular servicing avoid the dry-air feeling.
