Wall mounted air conditioning units are placed at a high-level on a wall and are ideal for smaller areas such as bedrooms, living rooms, offices, server rooms and shops. They are installed in a position that can supply the room with an even air flow. Wall units are exceptionally quiet and most people can sleep quite easily with the unit turned on.

Larger rooms may require multiple units spread evenly throughout the room to ensure that no areas are left out as this can create ‘hotspots’. Some installers will try to cut costs by suggesting that they install only one very powerful wall mounted unit, however, these more powerful wall units are usually intended for industrial or large commercial applications and can be too gusty and noisy for a domestic or office environment.

Using multiple smaller units will get the balance ‘just right’ eliminating gusts and reducing noise to provide the correct amount of cooling.
